Backup File Server Cluster

I have a windows 2008 file server cluster. We have an issue with our backups in backupexec where the jobs were decreasing performance on our network. We have our backup server configured for a new separate network. The file server
cluster is configured for our data network. Is there a way to make the file server cluster configured for both data network and backup network? I am trying to get out backup job of the file cluster to not degrade performance of our data network.
Sure! You can make your file server "listen" and respond to multiple networks. See all options listed here:

Good luck :)

Can anyone help me?Creating the shadow copies in the file server cluster ,there are some errors occured, OS version is WSS 2012

I construct a failover cluster(file server,AP module) for sharing files by WSS 2012,and I want to use the shadow copies to backup my data,but when making a shadow copies on the volume which is added to the cluster(not the CSV,just add
it to the cluster and use it to share files,it plays the role of file server),there are some errors occured, these errors result in the shadow copies failed,error likes the following pictures:
1: the disk F is added to the cluster,first I make the shadow copies by click the right key of mouse on the disk F,and chouse the configeration shadow copies,and click the settings, then click the schedule , and I wait just a few seconds, the error is appeared,like
this picture 1, the wait operation timed out,and then ,
I click the schedule button once again,a different error occured,like the following picture," the object already exists",if i don't set the schedule at first ,use the default shedule,and click the enable button also the same error must
accure
but the only diffrence is that, a shadow copy time point is created, also ,you can make the shadow copies by click " create now", that is creating the shadow copies manually. Although it can succesfully make the shadow copies, but when I select
a time point to revert, error occured, "A volume that contains operating system files or resides on a cluster shared disk cannot be reverted"
In a word,all the errors above make the shadow copies by schedulling failed,except making the shadow copies manually,but what makes me confused is that I have ever maked the shadow copies succesfully by schedul a policy,I don't know what makes it succesful,
it's small probability, most of time ,it's failed.No matter what kind of situation, revert must be failed.
I'm sorry for my pool english , it's the first time for me getting help in forum by english ,I don't know if I descripe my question clearly, also ,other method like the link
http://technet.microsoft.com/en-us/library/cc784118(v=ws.10).aspx I have tried,but the same errors occured.Can anyone tell me How can I make the shadow copies in File Server
cluster（AP module）？And I make a mistake in operating？ Looking forward for your reply.Thanks!

Hi,
Please check the following 2 places:
HKEY_LOCAL_MACHINE\Cluster\Tasks
C:\Windows\System32\Tasks
First please compare permission settings of the folder C:\Windows\System32\Tasks with a working computer. Correct permission settings if anything wrong. Specifically, confirm you current account do have permission on this folder.
As it said "object already exists", find the schedules you created before, backup and delete all these schedules in both registry key and folder.
Then test to create a new schedule to see if issue still exists.
Meanwhile what kind of storage device you are using? The issue could occur on specific storage device, so test to enable shadow copy on a local disk to see if that will work.

Thank you for you reply.On the local volume,all of these errors will not occur, but the volume in the file server cluser.There is no value in HKEY_LOCAL_MACHINE\Cluster\Tasks. On local volume, everything goes well about the shadow copy, so I do not
think something is wrong about the permission settings of the folder C:\Windows\System32\Tasks.Storage device is a SAN,we use RAID6 and provide the LUNs to the NAS engine, and the make the volume on these LUNs, Is Angthing wrong? Hope for you

Shadow Copies on 2012 R2 File Server Cluster

Hello all!
I've inherited a two node physical 2012 R2 file server cluster that contains a few SMB shares on a single clustered disk. I'd like to enable shadow copies for this shared disk but want to store the shadow copy data on its own shared disk
as per shadow copy best practices (at least on non-clustered file servers).
I created a second cluster disk, assigned it to the same resources as the SMB clustered disk.
Now historically I've enabled shadow copies through computer management but I want to ensure the shadow copies are cluster aware so in the Failover Cluster Manager I open Storage | Disks and right click the SMB cluster disk and click the Shadow Copies tab.
From the tab I can Enable shadow copies, this sounds like what I'm looking for, unfortunately it does not give me an option to choose a disk/volume to store my shadow copy data, so this can't be right.
My next step was to connect computer management to the cluster virtual server name (NOCFS4) and through the System Tools | Shared Folders | All Tasks | Configure Shadow Copies it shows me the correct number of shares on the SMB cluster disk plus
I can see the Settings button for configuring the location and size limit for shadow copies, however once I tweak the shadow copy location and size settings, click Ok and click Enable to turn on the shadow copies I get a long pause and an error about
not being able to create a schedule. So it seems connecting to the cluster virtual object is not the answer either.
That leaves using computer management to connect to one of the physical server nodes of the cluster. When I open the shadow copy interface on the physical node I note that it shows a 0 for the number of shares it detects on the SMB clustered disk.
This doesn't surprise me since this interface isn't cluster resource aware.
So I'm stuck. Does anyone know the "Microsoft way" to enable shadow copies on a clustered disk while storing the shadow copy data on a second cluster disk both attached to the same cluster resource?

Hi guys
I spotted exactly same problem right now on Windows 2012 R2 with latest updates.
Enabling Shadow Copy via Cluster Manager on disk will enable schedule and snapshots but schedule is not-cluster aware (is created locally on node) and "Previous Versions" are visible only locally but not via shared folders (UNC path accesible by
clients)
When I spotted this behavior I tried different way going via Computer Management and cluster resource name but console always hangs for me when using "Configure Shadow Copies". After many minutes configuration window is opened (Hurray!) but any
action there will hang whole console again. Enabling Shadow Copies will fail with "0x80004005: Unspecified
error" for creating scheduled task but "Next Run Time" column still shows "Disabled". Checking disk resource via Cluster Manager shows it is enabled and ?local? scheduled task is created.
Computer management console still shows DISABLED and any action freezes whole console (only when cluster resource name is used).
This fix I found, unfortunately, is not applicable to 2012 R2 OS: https://support.microsoft.com/en-us/kb/2894464
To sum up there is a major bug in MS implementation in Shadow Copies for Shared Folders when clustering is used or it is still not supported in 2012 R2? Doing it outside cluster works as it should (without freezes and Previous Versions are available via
UNC)
There is no documentation about FileServer Clustering on 2012(R2) unfortunately.
Could someone from MS clarify it?
Many thanks
Filip
EDIT:
Ok, one correction:
Scheduled task is not created in "Failover Clustering" hive of Scheduled tasks as user may expect but failover of fileshare to other node will unregister/reregister it on active node only.

File Server Cluster along with SQL Cluster

Hello There,
I have got SQL 2008 R2 cluster running on Windows 2008 R2 Ent OS.
Can i use the same cluster to host file server cluster? If yes is it advisable to do so.

1) Upgrade to Windows Server 2012 R2
2) Virtualize all of your workload (SQL Server, File Server etc)
After you'll be done it would be much easier to handle isolation inside your VMs and with a decent level of hardware resources allocated you'll have no issues running SQL Server and File Server @ the same time. If you don't virtualize I agree with Tim -
doable but not desirable :)

Windows Server 2012 R2 Scale out file server cluster using server disks as CSV

Hi,
My question is if I can create a Scale Out File Server Cluster with CSV using the disks that comes with the servers, we have 2 servers with 2 arrays each one, 1 array for the OS files and 1 array that we could use for the CSV.
Regards.

Hi,
a SoFS needs some kind of shared Storage, this could be in the old days ISCSI or FC SAN and now also a Shared SAS JBOD with Clustered Storage Spaces.
If you have 2 Servers with "local" Disks you need some sort of Software to create a Shared Disk Layer out of that local Disks, like Starwind or DataCore.

oh i forgot the normal 4th Option, some Kind of Clustered Raid Controller like HP or Dell offer in some Solutions.

Udo, clustered RAID controllers still require SAS disks mounted into external enclosure *OR* everything mounted into single chassis for Cluster-In-A-Box scenario (but that's for OEMs). The only two benefits somebody would have with them are a) ability to
privide RAID LUs to Clustered Storage Spaces (non-clustered RAID controllers would be used as a SAS controllers only in pass-thru mode) and b) abillity to have caches synchronized so VM moved from one physical host to another would not start from the "cold"
state. Please see LSI Syncro reference manual for details:

Server 2012 File Server Cluster Shadow Copies Disappear Some Time After Failover

Hello,
I've seen similar questions posted on here before however I have yet to find a solution that worked for us so I'm adding my process in hopes someone can point out where I went wrong.
The problem: After failover, shadow copies are only available for a short time on the secondary server. Before the task to create new shadow copies happens the shadow copies are deleted. Failing back shows them missing on the primary server as
well when this happens.
We have a 2 node (hereafter server1 and server2) cluster with a quorum disk. There are 8 disk resources which are mapped to the cluster via iScsi. 4 of these disks are setup as storage and the other 4 are currently set up as shadow copy volumes
for their respective storage volume.
Previously we weren't using separate shadow copy volumes and seeing the same issue described in the topic title. I followed two other topics on here that seemed close and then setup the separate shadow copy volumes however it has yet to alleviate the
issue. These are the two other topics :
Topic 1: https://social.technet.microsoft.com/Forums/windowsserver/en-US/ba0d2568-53ac-4523-a49e-4e453d14627f/failover-cluster-server-file-server-role-is-clustered-shadow-copies-do-not-seem-to-travel-to?forum=winserverClustering
Topic 2: https://social.technet.microsoft.com/Forums/windowsserver/en-US/c884c31b-a50e-4c9d-96f3-119e347a61e8/shadow-copies-missing-after-failover-on-2008-r2-cluster
After reading both of those topics I did the following:
1) Add the 4 new volumes to the cluster for shadow copies
2) Made each storage volume dependent on it's shadow copy volume in FCM
3) Went to the currently active node directly and opened up "My Computer", I then went to the properties of each storage volume and set up shadow copies to go to the respective shadow copy volume drive letter with correct size for spacing, etc.
4) I then went back to FCM and right clicked on the corresponding storage volume and choose "Configure Shadow Copy" and set the schedule for 12:00 noon and 5:00 PM.
5) I noticed that on the nodes the task was created and that the task would failover between the nodes and appeared correct.
6) Everything appears to failover correctly, all volumes come up, drive letters are same, shadow copy storage settings are the same, and 4 scheduled tasks for shadow copy appear on the current node after failover.
Thinking everything was setup according to best practice I did some testing by changing file contents throughout the day making sure that previous versions were created as scheduled on server1. I then rebooted Server1 to simulate failure. Server2
picked up the role within about 10 seconds and files were avaiable. I checked and I could still see previous versions for the files after failover that were created on server1. Unfortunately that didn't last as the next day before noon I was going
to make more changes to files to ensure that not only could we see the shadow copies that were created when Server1 owned the file server role but also that the copies created on Server2 would be seen on failback. I was disappointed to discover that
the shadow copies were all gone and failing back didn't produce them either.
Does anyone have any insight into this issue? I must be missing a switch somewhere or perhaps this isn't even possible with our cluster type based on this: http://technet.microsoft.com/en-us/library/cc779378%28v=ws.10%29.aspx
Now here's an interesting part, shadow copies on 1 of our 4 volumes have been retained from both nodes through the testing, but I can't figure out what makes it different though I do suspect that perhaps the "Disk#s" in computer management / disk
management perhaps need to be the same between servers? For example, on server 1 the disk #s for cluster volume 1 might be "Disk4" but on server 2 the same volume might be called "Disk7", however I think that operations like this
and shadow copy are based on the disk GUID and perhaps this shouldn't matter.
Edit, checked on the disk numbers, I see no correlation between what I'm seeing in shadow copy and what is happening to the numbers. All other items, quotas, etc fail and work correctly despite these diffs:
Disk Numbers on Server 1:
Format: "shadow/storerelation volume = Disk Number"
aHome storage1 = 16
aShared storage2 = 09
sHome storage3 = 01
sShared storage4 = 04
aHome shadow1 = 10
aShared shadow2 = 11
sHome shadow3 = 02
sShared shadow4 = 05
Disk numbers on Server 2:
aHome storage1 = 16 (SAME)
aShared storage2 = 04 (DIFF)
sHome storage3 = 05 (DIFF)
sShared storage4 = 08 (DIFF)
aHome shadow1 = 10 (SAME)
aShared shadow2 = 11 (SAME)
sHome shadow3 = 06 (DIFF)
sShared shadow4 = 09 (DIFF)
Thanks in advance for your assistance/guidance on this matter!

Hello Alex,
Thank you for your reply. I will go through your questions in order as best I can, though I'm not the backup expert here.
1) "Did you see any event ID when the VSS fail?
please offer us more information about your environment, such as what type backup you are using the soft ware based or hard ware VSS device."
I saw a number of events on inspection. Interestingly enough, the event ID 60 issues did not occur on the drive where shadow copies did remain after the two reboots. I'm putting my event notes in a code block to try to preserve formatting/readability.
I've written down events from both server 1 and 2 in this code block, documenting the first reboot causing the role to move to server 2 and then the second reboot going back to server 1:

We are using Symantec NetBackup. The client agent is installed on both server1 and 2. We're backing them up based on the complete drive letter for each storage volume (this makes recovery easier). I believe this is what you would call "software
based VSS". We don't have the infrastructure/setup to do hardware based snapshots. The drives reside on a compellent san mapped to the cluster via iScsi.
2) "Confirm the following registry is exist:
- HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VSS\Settings"
The key is there, however the DWORD value is not, would that mean that the
default value is being used at this point?

I've assigned the letter to the drive to which DPM was backing up, found the last file (the size was 0) and copied this file from the source without any problem.
This problem occurred several times with different storages for replica. Unfortunately previous logs went away so I cannot say that it stopped on the same file, but the error "Data corruption near MTF DBLK" was the same.
When the file server was on Windows 2008 R2 and DPM was 2012 SP1 there were no problems with backup.

Hi,
This is a known issue and is actively being investigated for a fix.

Backup / File Serving Plan - Your comments?

A local business would like to have a daily off-site backup, with incremental backups, and do file sharing from a single server across several users. Web based backup is probably not realistic as some files are 250 megs a pop. We have ordered an XSserve with three 750gig drives which we will use as a file server. My plan is to use Drive 1 for system files, with Drive 2 and 3 setup in Raid 1 for data files that will be mirrored. This will allow the owner to simply pull a drive out, put it in a case, and take it home with him each evening, while providing redundancy and up-time if a drive goes down.
It doesn't, however, ensure that if somebody deletes 200 pages from a document and mistakenly saves it, there will be any archived copy, so we will continue to use our current Retrospect backup plan, with some changes to frequency.
My current thinking with regard to the System files is to connect an external Hard Drive after the intitial setup has been finalized with the users added and use SuperDuper to clone the System hard drive and then disconnect it (after a verfifying boot from it). Backing up of that drive would be done manually when needed after adding users or doing updates that are verified to be "good" while not automatically backing up corrupted prefs or other problems that can tend to creep into a system.
Any thoughts or comments ?

My plan is to use Drive 1 for system files, with Drive 2
and 3 setup in Raid 1 for data files that will be mirrored.
This will allow the owner to simply pull a drive out, put it
in a case, and take it home with him each evening, while
providing redundancy and up-time if a drive goes down.
I'll be the contrarian on this one. Yes, it will work. Just fine (but see below). That's standard practice for many servers if you need them to be kept up 24/7, and a RAID 1 mirror split is the ONLY way to do an instantaneous clone of a drive. Other solutions (SuperDuper!, CCC, etc.) scan the disk, build a list, and copy files, such that any files that change/disappear/appear during or after the scan and before the copy will be missed. We do exactly that (well, not quite) with our Xserve G5 before doing any software update.
However, the approach we use is to add a spare drive to the mirror, allow the mirror to rebuild, then split the spare drive from the mirror. We use SoftRAID, and it has worked flawlessly for this (again, see below), and there is even a write-up on the SoftRAID web site (http://www.softraid.com) about this approach.
Realize, though, that such a mirror split has two issues. First, it is not a backup and it should not be confused with such. No archiving is done for old files, and it's not possible to go back weeks/months to get an inadvertently deleted file. A proper backup strategy (we use Retrospect to tape in an autoloader) is necessary for that.
Second, even though the mirror split is instantaneous, it still might not give a proper bootable image. Some programs, such as database programs (e.g., cyrus for email) maintain sets of files on disk that need to be consistent, and there needs to be (and is not) coordination between the instant of mirror split and all running services. For this reason, we shut down essential services (this can be scripted) such as email service, prior to the instant of mirror split, do the mirror split, then restart the services. Doing that avoids, for example, cyrus database corruption.
As mentioned above, we only do this for our OS volume, which is RAID 1 (SoftRAID) with mirror secondary being a RAID 5 LUN on an Apple Hardware RAID card and with mirror primary being a Seagate Cheetah attached to an ATTO UL4D. We add another mirror secondary (a Firewire drive) to the RAID 1 mirror, allow the mirror to rebuild, shut services by scripting, split the Firewire drive from the SoftRAID mirror, restart the services. Takes only an instant, gives a good bootable OS copy. Note that we only use this approach prior to any software change on the Xserve, allows us to roll back if the software change/update goes badly, as happened once. But that's all we use it for. We count on the RAID 5 LUN for our user data, plus our daily tape backups, to handle failures and accidental deletions, and we count on the RAID 1 mirror of the OS volume to handle failure of the Apple Hardware RAID card (which MUST have the write cache turned off - there is a bug in the card - fails to fully flush write cache on graceful power down - doubt Apple will ever fix this bug) and also to improve performance of the OS volume.
SoftRAID 3.5 is not scriptable, so this has to be done manually. I understand that scriptability is in the works, which would allow us to automate the process. SoftRAID 3.5.1 also has some issues with intel processors, the SoftRAID 3.6 beta just released resolves those issues (general release of SoftRAID 3.6 is expected shortly before MacWorld).
One thing for you to think about is all the handling/removal/insertion of the drive, and transporting the drive home each night. That will reduce the life of the drive and of the ADM connector into which the drive plugs.
I note upon re-reading your post that you use Retrospect, as do we. Be sure, before doing the mirror split (if you use this technique for your OS volume) that you disable Retrospect's schedule prior to the mirror split and then re-enable the schedule after the split. Otherwise, if you later try to boot from the earlier mirror split drive, all scripts with intervening scheduled times will be runnable and, just at the instant you are in a moment of crisis, trying to boot your precious backup copy, Retrospect will be firing off backups, etc. Been there, done that.
Good luck.

Windows 2012 R2 File Server Cluster Storage best practice

Hi Team,
I am designing Solution for 1700 VDi user's . I will use Microsoft Windows 2012 R2 Fileserver Cluster to host their Profile data by using Group Policy for Folder redirection.
I am looking best practice to define Storage disk size for User profile data . I am looking to have Single disk size of 30 TB to host user Profile data .Single disk which will spread across two Disk enclosure .
Please let me know if if single disk of 30 Tb can become any bottle neck to hold user active profile data .
I have SSD Writable disk in storage with FC connectivity.
Thanks
Ravi

Check this
TechEd session,
the
Windows Server 2012 VDI deployment Guide (pages 8,9), and
this article
General considerations during volume size planning:
Consider how long it will take if you ever have to run chkdsk. Chkdsk has gone significant improvements in 2012 R2, but it will still take a long time to run against a 30TB volume. That's down time..
Consider how will volume size affect your RPO, RTO, DR, and SLA. It will take a long time to backup/restore a 30 TB volume.
Any operation on a 30TB volume like snapshot will pose performance and additional disk space challenges.
For these reasons many IT pros choose to keep volume size under 2TB. In your case, you can use 15x 2TB volumes instead of a single 30 TB volume.

2012 R2 Standard File Server Cluster Confusion

Hi All:
I have 2 VMware 5.5 VMs running 2012 R2 Standard that have the Failover Cluster Manager role installed. I was having trouble validating the cluster before creating it & received this error:
Failed to find or allocate arbitration sectors for physical disk {fbf0422f-6844-4a3d-9ad9-542e8eebfec1} from node <SERVER>. These sectors are used to test reads
and writes to the disk. On a GPT disk, these sectors are located within the Cluster Metadata Partition, and this partition may need to be created from the Microsoft Reserved Partition so that the storage will validate. Please ensure that all GPT disks have
a Microsoft Reserved Partition (MSR) present. Error: 0x80070022.
I've been working w/Dell's VMware & SAN Support Teams & they sent me a link
https://social.technet.microsoft.com/Forums/windowsserver/en-US/d1524238-a891-4c7d-84ae-e885a9f59861/server-2012-clustering that says "you need to create an MSR partition on the drives", which I did on both my RDMs (1 for quorum; 1 for shared
storage). I ran the command after I selected the disk and now the disks look completely blank in Disk Management (I'd have to send a screenshot).
After that, cluster validation has no issues & I create the cluster. Now I cannot add either of the disks b/c:
Error Code: 0x8007174c
The disk is not configured in a way to be used with CSV. CSV disks must have a t least one partition that is formatted with NTFS or REFS.
So what did I do incorrectly? I had to use MSR to format the RDMs to validate the cluster, but now it wants another format. If anyone can find an actual MS document that goes into detail on where I went wrong, please include it,
as I've found nothing.
Thanks.

Just as the error say - you need to format the disks.
There are two steps to preparing a raw disk for use in a cluster. The first is to initialize it. That is what you did to get the cluster to actually see there were disks there to be used. The second is to put a file system on it by formatting
it. I recommend you use NFTS. Perform the format on just one of the nodes of the cluster.
Once you have an NTFS file system on the disk, you should be good to go.

Backup file server permissions?

Hello,
We have some file servers on Windows 2008 R2 and 2012 R2 and we have had times when admins have messed up the users folder permissions and shares, is there a way to back these up?
One admin recently reset permissions on 700 user folders!
Thanks

Hi,
This should help, use the built in reg and icacls command line utilities...

Failover cluster File Server role best practices

We recently implemented a Hyper-V Server Core 2012 R2 cluster with the sole purpose to run our server environment. I started with our file servers and decided to create multiple file servers and put them in a cluster for high
availability. So now I have a cluster of VMs, which I have now learned is called a guest cluster, and I added the File Server role to this cluster. It then struck me that I could have just as easily created the File Server role under my Hyper-V
Server cluster and removed this extra virtual layer.
I'm reaching out to this community to see if there are any best practices on using the File Server role. Are there any benefits to having a guest cluster provide file shares? Or am I making things overly complicated for no reason?
Just to be clear, I'm just trying to make a simple Windows file server with folder shares that have security enabled on them for users to access internally. I'm using Hyper-V Core server 2012 R2 on my physical servers and right now I have Windows
Server Standard 2012 R2 on the VMs in the guest cluster.
Thanks for any information you can provide.

Hi,
Generally with Hyper-V VMs available, we will install all roles into virtual machines as that will be easy for management purpose.
In your situation the host system is a server core, so it seems that manage file shares with a GUI is much better.
I cannot find an article specifically regarding "best practices of setting up failover cluster". Here are 2 articles regarding build guest cluster (you have already done) and steps to create a file server cluster.

File Server Failover Cluster without shared disks

i have two servers that i wish to cluster as my Hyper V hosts and also two file servers each with 10 4TB SATA disks, all i have read about implementing high availability at the storage level involves clustering the file servers (e.g SOFS) which require external
shared storage that the servers in the cluster can access directly. i do not have external storage and do not have budget for it.
Is it possible to implement some for of HA with windows server 2012 R2 file servers without shared storage? for example is it possible to cluster the servers and have data on one server mirrored real-time to the other server such that if one server goes
down, the other server will take over processing storage request using the mirrored data?
i intend to use the storage to host VMs for Hyper V fail-over cluster and an SQL server cluster. they will access the shared on the file server through SMB
each file server also has 144GB SSD, how can i use it to improve performance?

There are two ways for you to go:
1) Build a cluster w/o shared storage using MSFT upcoming version of Windows (yes, finally they have that feature and tons of other cool stuff). We've recently build both Scale-Out File Server serving Hyper-V cluster and standard general-purpose File Server
cluster with this version. I'll blog next week edited content (you can drop me a message to get drafts right now) or you can use Dave's blog who was the first one I know who build it and posted, see :
Windows Server Technical Preview (Storage Replica)
http://clusteringformeremortals.com
Feature you should be interested in it Storage Replica. Official guide is here:
Storage Replica Guide
http://blogs.technet.com/b/filecab/archive/2014/10/07/storage-replica-guide-released-for-windows-server-technical-preview.aspx
Will do things like on the picture below:
Just be aware: feature is new, build is preview (not even beta) so failover does not happen transparently (even with CA feature of SMB 3.0 enabled). However I think tuning timeout and improving I/O performance will fix that. SoFS failover is transparent
even right away.
2) If you cannot wait 9-12 months from now (hope MSFT is not going to delay their release) and you're not happy with a very basic functionality MSFT had put there (active-passive design, no RAM cache, requirement for separated storage, system/boot and dedicated
log disks where SSD is assumed) you can get advanced stuff with a third-party software doing things similar to the picture below:
So it will basically "mirror" some part of your storage (can be even directly-accessed file on your only system/boot disk) between hypervisor or just Windows hosts creating fault-tolerant and distributed SAN volume with optimal SMB3/NFS shares.
For more details see:
StarWind Virtual SAN
http://www.starwindsoftware.com/starwind-virtual-san/
There are other guys who do similar things but as you want file server (no virtualization?) most of them who are Linux/FreeBSD/Solaris-based and VM-running are out and you need to check for native Windows implementations. Guess SteelEye DataKeeper (that's
Dave who blogged about Storage Replica File Server) and DataCore.
Good luck :)
StarWind VSAN [Virtual SAN] clusters Hyper-V without SAS, Fibre Channel, SMB 3.0 or iSCSI, uses Ethernet to mirror internally mounted SATA disks between hosts.

File server on cluster

Hi
I have failover cluster on win server 2008 R2 that host file service fro 2 nodes (File1 , File2)
I make failover with no issues but once i failover to file server1 some users cannot access the shared volumes
some users when they make logoff and login they also cannot access the shared volumes
what was this issue ?
need help and how can i monitoring ?

Hi Yasser Mohamed Abdel Moneim,
In file server cluster if we need to create the share folder we need to use the failover clsuster manager, did you create the share folder with clsuter manager?
The related KB:
Create a Shared Folder in a Clustered File Server
https://technet.microsoft.com/en-us/library/cc732302.aspx?f=255&MSPPError=-2147217396
I’m glad to be of help to you!
Please remember to mark the replies as answers if they help and unmark them if they provide no help. If you have feedback for TechNet Support, contact [email protected]
This is not the issue at all
It is working since 1 week the issue when we make failover the shared volume become not accessible
