Selecting VHDx as storage for File Server Role (Failover Cluster 2012 R2)

Is it possible to select an already existing (offline) VHD or VHDX as storage when creating the "File Server" role? Reason I want to do that is because I already have a file server setup as a virtual machine and causing issues so my company
decided to make the change towards a File Server role.
Thank you
David

Hi David,
Do you mean you configured it to file server failover cluster via "High Availability Wizard" ?
I think you need to choose a shared volume between two nodes to achieve high availability .
Please refer to following link :
http://technet.microsoft.com/en-us/library/cc731844(v=WS.10).aspx
If you do not select a shared volume , I think there is no difference than sharing a mounted VHDX file on a standalone file server .
I would suggest to copy these files to CSV and share them .
Hope it helps

Error while adding file share for File Server role

I'm getting this error when trying to add a file share on a Server 2012 R2 failover cluster:
"Unable to retrieve all data needed to run the wizard. Error details: Cannot retrieve information from server. Error occurred during enumeration of SMB shares: WinRM cannot complete the operation. Verify that the specified computer name is valid, that
the computer is accessible over the network, and that a firewall exception for the WinRM service is enabled and allows access from this computer. By default, the WinRM firewall exception for public profiles limits access to remote comptuers within the same
local subnet."
Despite the message, I can still create the share and it seems to work, but I'm concerned there may be an issue and I'd like to resolve it before putting the service into production. TIA!

Hi,
Your error often caused by the WinRM can’t communication to the others node, please confirm all the node “Windows Remote Management” service is running or try to disable your
firewall and AV soft then monitor it again.

Migrating single file server to failover cluster file server

Hi,
Currently we have one file server which is our Domain controller also. File Server data stored in SAN storage lun. Users home folders also resides at file server.Now we want to create 2 node failover cluster file server.
Questions:
1)Can we assign same storage lun to failover cluster?
2)Do we need to assign all permissions and storage quota again?
What is the best option to achieve this goal.

Hi,
if you attach the same LUN to the failover cluster the NTFS permission (security tab) are retained because they are stored in the LUN itself
Share permission are lost because they are stored in the registry of the file server. If you have few share with a simple share permission structure, simply recreate them in the cluster. If you have a lot of shares and complex permission tree, you have to
export registry hives related to lanmanserver\shares

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.

Windows 2012 Failover Cluster - File server role (vCO)

Hi,
I wonder if anybody can shed some light on a query i have.
A windows 2012 failover cluster will be built in AD domain example.uk. Cluster File server roles will be created and will reside in this domain also.
We also have a requirement to run a cluster file server role in the child domain off secure.example.uk. Is this possible? or do the file server roles and related vCO's have to reside in the same domain as the cluster (CNO).
I know the CNO can be used to create the VCO but could a prestage a VCO in the child domain of secure.example.uk.
Mark

Hi Mark,
By default CNO will create
VCO automatically in default domain computer OU, we generally use the
KISS principle to place the CNO and VCO to the same OU, and as far as I know there no known design document indicate the VCO can be placed in different domain, therefore I suggest you place the CNO and V CO at same OU.

High availability for file server and exchange with 2 physical servers

Dear Experts,
I have 2 physical server with local disks only. I want to setup below on same with high availability, please advise best prossible options. We will be using windows 2012 R2 Server..
1. Domain controller
2. Exchange 2013
As of now I am thinking of setting up below:
1. Install Hyper-v on both and create 3 VM on each as
-On Host A- 1 VM for DC, 1 VM for File server with DFS namespace and replication for file server HA and 1 VM for Exchange 2013 with CAS/MBX with DAG and DNS RR for Exchange HA
-On Host B - 1 VM for ADC, 1 VM for File server DFS member for above and 1 VM for Exchange 2013 CAS/MBX with DAG member
I have read on internet about new features called scale out file server (SoFS) in Windows 2012 Server but not sure that will be preferred for file sharing.
Any advise will be highly appreciated..
Thanks for the help in advance..

Best regards,
DFS is by far the best way to implement any sort of file server. Because a) failover is not fully transparent and does not happen always (say not on copy ) b) DFS cannot replicate open files so if you edit a big file and have node rebooted you're going to
lose ALL transactions/updates you've applied c) actually slows down the config. See:
DFS for failover

(check "open files" point here)
DFS Performance
http://blogs.technet.com/b/filecab/archive/2009/08/22/windows-server-dfs-namespaces-performance-and-scalability.aspx
SoFS a) requires shared storage to run and you don't have one b) does not support generic workloads
(only Hyper-V and SQL Server) and c) technically makes sense to expand SAS JBOD or existing FC SAN to numerous Hyper-V clients over 10 GbE w/o need to invest money into SAS switches and HBAs and FC HBAs and new licenses FC ports. Making long story short:
SoFS is NOT YOUR CASE.

http://www.aidanfinn.com/?p=12786
http://www.aidanfinn.com/?p=12786
For now you need to find some shared storage to be a back end for your hypevisor config (SAS JBOD from supported list, virtual SAN from multiple vendors like for example StarWind see below, make sure you review ALL the vendors) and then you create a failover
SMB 3.0 share for your file server workload. See:

HT204053 best storage for filies deleted but used frequently wd drop box flash drive

best storage for filies deleted but used frequently wd drop box flash drive

Thanks LowLuster! With that info I have another questions if that's ok. First, I'm sure it's formatted to fat32. I have learned I can't transfer movies over 4gb. I use an external hard drive for those. The files are ones I've downloaded from YouTube in the mp4 format and are never over 1gb. They're all mb in size.
I didn't realize flash drives had limited writes. Is there any way to confirm I've reached the limit? Both times I reformatted it I was able to add back the videos I previously had on it. I would say there were a hundred or so. Both times I left some "growing room" on the flash drive so I could add more files. And, both times I was able to continuing adding until I had reached the max capacity. The problem occured after I tried deleting files to free up space. Does this make sense with "the amount you have used it" theory? Does it start to become buggy at that point, or does it just make writes to the drive impossible?
Thanks

File Server Role: Slow access for "opened files" and slow Explorer browsing

Since we migrated our fileserver from Windows Server 2008 R2 to Windows Server 2012 we are facing two major problems:
1. Opening files which are already opened by other users takes about 1 minute before the file actually opens. This is not only for Office files such as Excel and Word, but also for other (not office) files. Again, this problem only rises when the file(s)
is/are already opened by another user. There seems to be a sort of "Lock" check time which is about 45 to 60 seconds.
2. The other problem is browsing via Explorer through the network drive (all clients are Windows 7 clients). Half of the time there is some kind of "hick up" with displaying the results of the folder. I cannot figure out a patern, but if there
is no "hick up" then browsing is very fast (also in the busiest times of the working day)... If there is a "hick up" the result can take about 50 seconds to display the content of a folder.
I suspect the SMB implementation / settings of Windows Server 2012 which are causing the problems...
Things I tried:
1. Changed the Oplocks wait time to 10 seconds (which is the minimum). The result is that openening files does indeed go some faster (still taking about 45 seconds).
2. Disabled SMB2: the result is that browsing is fast... Opening files does go faster. BUT: we are then facing other problems like some files are not able to open... This setting was, after getting a lot of complaints from the users, changed back to enabled
SMB2.
3. Within the NIC card properties I disabled "QoS packet Scheduler", "Link-Layer Topology Discovery Mapper I/O Driver", "Link-Layer Topology Discovery Responder" and IPv6 (as we only use IPv4).
All above with not the promising results.
The server is a dedicated (virtual machine on vSphere 5.1) fileserver.
Please Advice since this is not workable, and we have postponed the migration of the fileserver for our aother location.

Hi Dave,
I suggest you disable all third party applications like Anti-Virus application to test if it could reduce the waiting time when accessing a file.

Failover cluster server - File Server role is clustered - Shadow copies do not seem to travel to other node when failing over

Hi,
New to 2012 and implementing a clustered environment for our File Services role. Have got to a point where I have successfully configured the Shadow copy settings.
Have a large (15tb) disk. S:
Have a VSS drive (volume shadow copy drive) V:
Have successfully configured through Windows Explorer the Shadow copy settings.
Created dependencies in Failcover Cluster Server console whereby S: depends on V:
However, when I failover the resource and browse the Client Access Point share there are no entries under the "Previous Versions" tab.
When I visit the S: drive in windows explorer and open the Shadow copy dialogue box, there are entries showing the times and dates of the shadow copies ran when on the original node. So the disk knows about the shadow copies that were ran on the
original node but the "previous versions" tab has no entries to display.
This is in a 2012 server (NOT R2 version).
Can anyone explain what might be the reason? Do I have an "issue" or is this by design?
All help apprecieated!

Hi,
Please first check the requirements in following article:
Using Shadow Copies of Shared Folders in a server cluster
http://technet.microsoft.com/en-us/library/cc779378(v=ws.10).aspx
Cluster-managed shadow copies can only be created in a single quorum device cluster on a disk with a Physical Disk resource. In a single node cluster or majority node set cluster without a shared cluster disk, shadow copies can only be created and managed
locally.
You cannot enable Shadow Copies of Shared Folders for the quorum resource, although you can enable Shadow Copies of Shared Folders for a File Share resource.
The recurring scheduled task that generates volume shadow copies must run on the same node that currently owns the storage volume.
The cluster resource that manages the scheduled task must be able to fail over with the Physical Disk resource that manages the storage volume.
If you have any feedback on our support, please send to [email protected]

Best Practice for General User File Server HA/Failover

Hi All,
Looking for some general advice or documentation on recommend approaches to file storage. If you were in our position how would you approach adding more rubustness into our setup?
We currently run a single 2012 R2 VM with around 6TB of user files and data. We deduplicate the volume and use quota's.
We need a solution that provides better redundancy that a single VM. If that VM goes offline how do we maintain user access to the files.
We use DFS to publish file shares to users and machines.
Solutions I have researched with potential draw backs:
Create a guest VM cluster and use a Continuosly Available File Share (not SOFS)
- This would leave us without support for de-duplication. (we get around 50% savings atm and space is tight)
Create a second VM and add it as secondary DFS folder targets, configure replication between the two servers
- Is this the prefered enterprise approach to share avialability? How will hosting user shares (documents etc...) cope in a replication environment.
Note: we have run a physical clustered file server in the past with great results except for the ~5 mins downtime when failover occurs.
Any thoughts on where I should be focusing my efforts?
Thanks

If you care about performance and real failover transparency then guest VM cluster is a way to go (compared to DFS of course). I don't get your point about "no deduplication". You can still use dedupe inside your VM just will have sure you "shrink" the VHDX
from time to time to give away space to host file system. See:

HI Chris,
Sharing files using Bluetooth
To share files using Bluetooth, you first need to make sure Bluetooth is turned on, and then use Bluetooth File Exchange to send a file.
To turn on Bluetooth:
Choose Apple menu > System Preferences and click Bluetooth.
Select the On checkbox. To allow other Bluetooth enabled devices to “discover” your computer and send files, also select the Discoverable checkbox.
Select “Show Bluetooth status in the menu bar” so you can quickly send files and perform other actions using the Bluetooth status menu in the menu bar.
To send files using Bluetooth:
Choose Send File from the Bluetooth status menu in the menu bar.
If the Bluetooth menu isn’t visible, choose Apple menu > System Preferences, click Bluetooth, and select “Show Bluetooth status in the menu bar.”
In the window that appears, select the file you want to send and click Send.
Select the device you want to send the file to and click Send.
If you don’t see the device you want to send the file to, make sure the device has Bluetooth turned on and is discoverable.
You do not need File Sharing turned on for Bluetooth technology.

IMac freezes at login screen for file server

The machine: iMac (lampshade), OS 10.3.9
The symptom: During the boot/login sequence, the machine locks up at the login screen to the file server.
If I disconnect the network cable during the boot sequence, it will error but not freeze; I can later reconnect the cable and login without a problem.
Any ideas?
James

You may want to look at this similar post:

Heres what Mac Help said.
Open System Preferences and click Startup Disk.
If necessary, click the lock icon and type the name and password for an administrator user.
Click the icon of the system folder or system volume that you want to use, then click Restart.
IMPORTANT: When selecting a network startup volume, be sure you select a valid network startup volume and not a network install image. Choosing a network install image reinstalls your system software and may erase the contents of your hard disk. A standard network volume icon appears as a globe and Mac OS X system folder. When you select a network volume icon, a message appears in the Startup pane describing the volume. A network install icon appears as a globe with downward pointing green arrow.
Another way to select a startup disk is to hold down the Option key as you restart your computer. You'll see the available startup disks and can select one.
If your computer is on a network and a network startup volume is available, you can start up from the network startup volume by holding down the N key as you restart your computer.

No more connections available to this remote computer...Urgent Help for File server...

Hi Guys,
I need urgent help regards to our school File server which is having "No more connection to this remote computer error"
on SMB Shares where I usually authenticate with a domain username it used to work fine since till 3 weeks ago.
Now I can browse the SMB shares with only IP... Netbios gets straight away this error message from non-domain joined pc's where the computer needs to connect to the SCCM distribution point on this file server.
Strangely, Domain joined pc's does not have this problem at all they can use Netbios or IP no problem at all. But someone from a standalone laptop or desktop who needs to access shares through netbios gets this message.
Can someone help me please?
I did check DNS yet there is no problem on DNS I checked PTR record for the server to make sure it is not turned in to multihome accidently but nothing at all.
I also did a NETMON where I captured the data from server and the client I get these errors:

Solution has been found,
After doing bit of a backtrack, site DC's were out of sync with PDC with time.
Also Time service was shutdown on PDC which has been enabled and pointed to the Australian pool ntp IP address.
Everything is back on track now.

Mini vs iMac vs MacPro for file server?

I need a machine to serve as a home server and do some video encoding on the side (my dvd collection). As this machine would remain running 24x7, would the mini be the best choice because of low power consumption? Maybe the imac for more internal staorage available? I have a MacPro as my main machine but not sure I want to a server and client running on the same machine?

I agree.
You don't need to buy the Server version of the Mini, adding external hard drives is far more cost effective, so unless there are features of OS X Server that you actually need stick with the normal version. Plus you probably want the DVD drive.
Far more cost effective?
2.66 GHz Mac Mini with 8GB of RAM (since you'll want to max out the RAM for your video work), a 500GB internal HDD @ 5400 RPM, and an internal SuperDrive: $1449 from Apple's online store
2.66 GHz Mac Mini Server with 8GB of RAM, 2x500GB internal HDD storage @ 7200 RPM (which will speed things up further; the extra RPM isn't just for show), and an external SuperDrive: $1498 from Apple's online store
Even if you were to get the normal Mini's 320GB HDD and make up the difference with a 1TB external HDD, you'd basically still arrive at the price of a Mac Mini Server with the above listed options (and this is assuming you'd even NEED an external DVD drive for the Server; I've been doing fine without so far, using my MBP as my Server's SuperDrive when needed), and with 320GB of your storage at a slower access speed than what you'd get with the Server. Not to mention that this is not even including the price difference of Snow Leopard Server vs. Snow Leopard Client + bundled iLife.
So not only is this certainly not far more cost effective, one could argue it is, in the end, *more expensive*!
