Server 2012 R2 Storage Pool Disk Identification Method

Hi all,
I'm currently using Server 2012 R2 Essentials with a Storage Space consisting of 7 3TB disks. The disks are connected to an LSI MegaRAID controller which does not support JBOD so each disk is configured as a single disk RAID0. The disks are connected to
the controller using SAS Breakout Cables (SATA to SFF-8087).
I am considering moving my server into a new chassis. The new chassis has a SAS Backplane for drive attachment which means I would be re-cabling to use SFF-8087 to SFF-8087 cables instead and in doing so, the channel and port assignment on the LSI MegaRAID
will change.
I know that the LSI card will have no problem identifying the disk as the same disk when it's connected to a different port or channel on the controller, but is the same true for the Storage Space?
How does Storage Spaces track the identity of the individual disks?
Just to be clear, the hardware configuration otherwise will not be changing. Motherboard, CPU, RAID controller etc will all be the same, it will just be moving everything into a new chassis.

Hi,
If the disks are still recognized as the same, the storage space should be recognized as well.
You could test to do the replacement and see if the storage pools are being recognized. If not you can still change them back with original devices and storage pools will back to work. Then we may need to find a way to migrate your data. Personally I think
it will work directly.
Note: backup important files is always recommended.

VirtualDisk on Windows Server 2012 R2 Storage Pool stuck in "Warning: In Service" state and all file transfers to and from is awfully slow

Greetings,
I'm having some trouble with my Windows Storage Pool and my VirtualDisk running on a Windows Server 2012 R2 installation. It consists of 8x Western Digital RE-4 2TB drives + 2x Western Digital Black Edition 2TB drives and have been configured in a single-disk
parity setup and the virtual disk is running fixed provisioning (max size) and is formatted with ReFS.
It's been running solid for months besides some awful write-speeds at times, it seems like the write performance running ReFS compared to NTFS is not that good.
I was recommended to add SSD's for journalling in order to boost write-performance. Sadly I seemed to screw up this part, you need to due this through PowerShell and it needs to be done before creating the virtualdisk. I managed to add my SSD to the Storage
Pool and then remove it.
This seem to have caused some awkward issues, I'm not quite sure of why as the virtualdisk is "fixed" so adding the SSD to the Storage Pool shouldn't really do anything, right? But after I did this my virtual disk have been stuck in "Warning:
In Service" and it seems to be stuck? It's been 4-5 days and it's still the same and the performance is currently horrible. Moving 40GB of data off the virtual disk took me about 20 hours or so. Launching files under 1mb of the virtual disk takes several
minutes etc.. It's pretty much useless.
The GUI is not providing any useful information about what's going on. What does "Warning: In Service" actually imply? How am I supposed to know how long this is supposed to take? Running Get-Virtualdisk in PowerShell does not provide any useful
information either. I did try to do a repair through the Server Manager GUI but it goes to about 21% within 2-3 hours but drops back down to 10%. I have had the repair running for days but it wont go past 21% without dropping back down again.
Running repair through PowerShell yields the same results, but if I detach the virtual disk and then try to repair through PowerShell (the GUI wont let me do repair on detached virtual disks) it will just run for a split second and then close.
After doing some "Googeling" I've seen people mentioning that the repair is not able to finish unless I have at least the same amount of free space in the Storage Pool as the largest drive in my Storage Pool is housing so I added a 4TB drive as
due to me running fixed provisioning I had used all the space in the pool but the repair is still not able to go past 21%.
As am running "fixed provisioning" I guess adding a extra drive to the pool doesn't do much difference as it's not available for the virtual disk? So I went ahead and deleted 3 TB of data on the virtual disk so now I've got about 4 TB free space
on the virtual disk so there should be plenty of room for Windows Server 2012 R2 to re-build the parity or whatever it's trying to do but it's still the same, the repair wont move past 21% and the virtual disk is still stuck in "Warning: In Service"
mode and the performance keeps being horrible so taking a backup will take forever at these speeds...
Am I missing something here? All the drives in the pool is working fine. I have verified using various bootable tools so why is this happening and what can I do to get the virtual disk running at full state again? Why doesn't the GUI prompt you with any
kind of usable information?
Best regards, Thomas Andre

Hi,
Please run chkdsk /f /r command on the virtual disk to have a try. In the meantime, run the following commands in PowerShell to share the output.
get-virtualdisk -friendlyname <name> | get-physicaldisk | fl
get-virtualdisk -friendlyname <name> |fl

First cluster - Server 2012 r2 - storage spaces issues

Hi Everyone
   We just purchased two new servers (Lenovo RD640's) and an external SAS JBOD enclosure (the Lenovo SA120), and we would like to set up a 2012 r2 failover cluster with clustered storage spaces as the shared storage. Currently they are
on their own domain with the virtual active directory server residing locally on one of the servers.
   Preface: I've created and destroyed the cluster and storage spaces multiple times trying to solve this issue, so I don't know if I may have "leftovers" from those attempts now causing issues for me.
I can create the cluster, and it passes validation, and can create a clustered storage pool, but every time I try to create a virtual disk (either through the Failover cluster manager, the server manager, or powershell), it won't attach. If
I try to manually attach it I get the message: "Error attaching or detaching virtual disk: Failed to attach virtual disk to <node name>. Access denied"
Finally (and I don't know if this is related or not), when in storage spaces on the server manager, there is a gold banner at the top that says "Incomplete communication with cluster <cluster name>. The following cluster nodes or clustered roles
might be offline or have connectivity issues: <cluster name>"
I'm logged in with full domain administrator credentials, and have been running my head against this wall for a few days now. Any help would be appreciated!

Thanks for your responses. Here is what I have to report:
When I destroy the cluster, and create the storage spaces on just one of the two servers (with the other server powered down), I'm able to create the storage pool - using all the HDDs and SSDs - and virtual disks (both tiered and non-tiered) without issue.
As soon as I create the cluster again, the virtual disks become "detached", and I'm back to the situation described initially.
@Apamnapat, here's the output of the powershell commandlets you suggested:

Server 2012 Failover Cluster No Disks available / iSCSI

Hi All,
I am testing out the Failover Clustering on Windows Server 2012 with hopes of winding up with a clustered File Server once I am done.
I am starting with a single node in the cluster for testing purposes; I have connected to this cluster a single iSCSI LUN that is 100GB in size.
When I right click on Storage -> Disks and then click 'Add Disk', I get No disks suitable for cluster disks were found.
I get this, even if I add a second server to the cluster, and connect it to the iSCSI drive as well.
Any ideas?

For testing purpose you'd better spawn a set of VMs on a single physical Hyper-V host and use shared VHDX as a back clusterd storage. That would be both much easier and much faster then what you do. + it would be trivial move one of the VMs to another physical
host, shared VHDX to CSV on a shared storage and go from Test & Development to production :) See:
Shared VHDX

For a pure iSCSI scenario you may try this step-by-step guide (just skip StarWind config as you do have a shared storage already with your SAN). See:
Configuring HA File Server on Windows Server 2012 for SMB NAS

Hope this helped a bit :)
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.

Server 2012 RDS - User Profile Disks

Hello,
I'm implementing Server 2012 RDS session-based.
Can I increase the limit of User Profile Disk after it is initially set?
Is it ok that my Admin user has a User Profile Disk i.e. no local profile on the server as they did previously.
Are PSTs supported on User Profile Disks - previously PSTs were unsupported on network share - User Profile Disks are on network share.
I had an issue where a UPD was created for a user - I then delete the UPD. I then logged in as the user (a domain admin) and expected a local profile to be created - this didn't happen. A temporary profile was created instead. This was unexpected.

Hi Gary,
You can try to change the size of User Profile Disk by mounting .Vhdx file. Please refer below thread for information.
Resize User Profile Disks
As per my research, i can suggest you to use admin local user profile on server.You can get more information for UPD on below listed article.
1. Easier User Data Management with User Profile Disks in Windows Server 2012
2. Using User Profile Disks (UPD) in combination with predefining the Modern UI Start Screen on RDS 2012 (appsfolder.itemdata-ms)
Hope it helps!
Thanks,
Dharmesh

Server 2012 RDS - User Profile Disks - Errors during Logoff

I have set up a test Server 2012 RDS collection (Single Server for now) and implemented User Profile disks.
I have two problems.
First: My generic test user can connect and does successfully use the user profile disk as expected. However, at
logoff, the system event log contains these errors:
The error (NTFS 137) is: The default transaction resource manager on volume C:\Users\ts3.test encountered a non-retryable error and could not start. The data contains the error code.
The warning (NTFS 50) that concerns me is:
It appears that the user profile disk is being "disabled" or "disconnected"
before the profile data is completely written at logoff. What can I do to troubleshoot this?
Second:
Update: A post from Mike Connor on the following page: -LINK- solved
the problem described below.
My administrative user always logs on now with a temporary profile. At the beginning, the UPD was working and mounting. That stopped working. In attempting to troubleshoot, I logged the admin user off and deleted the UPD disk
file from the share. I remember it working again after generating a new UPD disk file in the share. Soon, it quit working again. I deleted the UPD disk file again from the share and ever since, it has never regenerated a new UPD and
always logs on with a temporary profile.

We experience less to zero problems after an outage with our User Profile Disks when we use the option: "Store all user settings and data on the user profile disk". Other then when we use the other checkbox (even though all checkboxes
underneath are checked).
Our test setup was, an RDSH 2012 r2 server(s), with an 2012r2 server holding the share.
We first tried the "store all user settings" for the User Profile Disk, we logged several accounts onto our RDSH Server we then disconnected our server which holds the share to simulate an outage. After about 5 minutes we connected the
server again holding the share. When the share comes back online, we logged off the users and logged them back in. The result was a valid profile for all the accounts including their last changes from before the share got disconnected.
The exact same test was done with the option: "Store only the following folders on the user profile disk" with all checkboxes underneath checked, which gave us corrupt profiles.. We also did these tests by giving the server holding the share a reboot instead
of an disconnect from network. This gave us the same result. Each test was done at least 2 to 3 times..
I hope others can confirm this as well in their situation, as it seems to be a bug within that specific checkbox.
Looking at the above tests, the best way in my test cases were to exclude the default folders (f.e.: \Documents) if you would like to redirect them instead of using them inside your User Profile Disk. Redirects can be done through GPO Folder redirection
options or GPO registry combined with Environment Variables.
Even after several attemps to simulate an outage, i get left with consistent profiles. I've now also included an hard reset of my virtual machine (that gave the same results as a disconnect of the network card). This was all done through using the: "Store
all user settings in the user profile disk". The other option left us with inconsistent profiles. I hope others can confirm this as well..
Looks to me that the type of connection towards the User profile happens different. You can see this when looking at the C:\users\<username> and subfolders if you use user profile disks. The 2 options show different symbols as well.

Server 2012 R2 user profile disks and outlook search not working

Hi,
I`m having a problem with my setup for quite some time now with Windows Search and indexing the outlook OST files.
I`m using user profile disks in my setup but it seems that Windows Search can`t index the user profile disks, hence when i`m searching in outlook (the OST file is located in the user profile disk) with windows search enabled i`m not getting any results because
it can`t index the OST file.
If I don`t use the disks then windows search works fine but because i`m using clustered TS servers I need the profile disks and I don`t want to go back to redirects if possible..
At the moment I`ve disabled Windows Search which forces outlook to search online, it works but is slow..

Next issue that popped up, after the user logs off it will deleted the indexed data and start over the next time the user logs on..
Any fix for that?
There are three other Technet threads describing the same exact problem about indexing data being deleted when a user logs off from RDS. I'm experiencing this bug also and haven't found anything to fix it yet.

Can't find the all disks in storage pool

Hello
I have Windows server 2012 R2 installed in KVM. I would like to create storage pool on 2 virtual disks.
I use whole new two virtio type disk.
I could see that there's two attached disks.virtio is recognized SCSI bus type.
But I can't find all the disks in storage pool.
No matter how many virtio disks I add, I could only see the first disk I mounted.
Could tell me why? Are multiple virtio type disks not allowed in server 2012 R2 storage pool?

After I initialized the 2 disks as GPT, it is still only recognized the first mounted disk.
Does it might be related to the virtio disk type?
Have you ever tried this situation?

DPM 2010; migrated DPM protection group to new storage pool ; data on source disk is not expiring

I am running DPM 2010 with 4 storage pool disks. 2 are iSCSI; 1 is SAS; the fourth, also iSCSI, was recently deployed to replace the SAS storage pool disk.
(1) iSCSI
(2) iSCSI
(3) SAS - Source
(4) iSCSI - Destination
Initially we tried to migrate the entire data source (3) to the new iSCSI storage pool disk destination (4). This failed
Set-ProtectionGroup: The allocation of disk space for storage pool volume failed because there is not enough unallocated disk space in the storage pool (ID: 358). (Sorry, I was not allowed to attach an image).
We believe the source disk previously created dynamic links to the long-term retention device (tape) which resulted in exceeding the available space on the new destination iSCSI storage pool disk. The source storage pool disk was totaling ~2.5TB, but needed
~9TB for the destination.
Instead I've tried to migrate the DPM protection group. The migration was successful. I followed the procedure outlined here
"Microsoft DPM 2012 Sp1 – How To Migrate Data Source using MigrateDatasourceDataFromDPM by ICTtechie" (Sorry, I was not allowed to include a link).
My understanding / expectation was that the data on the source disk would expire within 5 days (as this is our retention time set for disk replication); instead data started to expire from the other 2 iSCSI (1), (2) storage pool disks.
What am I missing here?
Thanks

Ok - you may have bumped into this.

Windows storage server 2012 share not connecting by share name but connecting thru IP address from windows XP machines

We have a windows storage server 2012 (HP storage server) in our domain. All of sudden We had a issue, connecting the server shares using the share name only from XP machines, but it is connecting through IP address with a delayed response. We are getting
the below error message from all the windows XP SP2 machines in our domain.
"\\<share name> is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have a access permissions.
Login Failure: The target account name is incorrect."
But it is connecting while we are trying from windows 7 machines. Also the other server shares (Windows 2003 server) are connecting without any issues using the share name. In addition to this we gave everyone permission for this share. And it worked
well before but not now. Could you please suggest any solution for this complex issue?
Thanks,

Cluster Quorum Disk failing inside Guest cluster VMs in Hyper-V Cluster using Virtual Disk Sharing Windows Server 2012 R2

Hi, I'm having a problem in a VM Guest cluster using Windows Server 2012 R2 and virtual disk sharing enabled.
It's a SQL 2012 cluster, which has around 10 vhdx disks shared this way. all the VHDX files are inside LUNs on a SAN. These LUNs are presented to all clustered members of the Windows Server 2012 R2 Hyper-V cluster, via Cluster Shared Volumes.
Yesterday happened a very strange problem, both the Quorum Disk and the DTC disks got the information completetly erased. The vhdx disks themselves where there, but the info inside was gone.
The SQL admin had to recreated both disks, but now we don't know if this issue was related to the virtualization platform or another event inside the cluster itself.
Right now I'm seen this errors on one of the VM Guest:

We don't know if this can happen again, what if this happens on disk with data?! We don't know if this is related to the virtual disk sharing technology or anything related to virtualization, but I'm asking here to find out if it is a possibility.
Any ideas are appreciated.
Thanks.

System Center 2012R2 Storage Pool Deduplication?

I am trying to find out if it is possible to deduplicate data on a System Center 2012R2 Storage Pool on Server 2012R2. I am aware that DPM will back up deduplicated data in a deduplicated state, but this is about deduplicating data backed
up from multiple sources. Searching shows me that deduplicating System Center 2012 Storage Pools on Server 2012 was not supported, but the threads I found that showed this either had screenshots or quotes of the information instead of links to the documentation.
Is it possible/supported to deduplicate data within a System Center 2012R2 Storage Pool on Server 2012R2?

Hi,
Yes, if you virtualize your DPM server, it is possible to enable deduplication of DPM storage pool disks.
Please see the following white paper:
Deduplicating DPM storage
We are working on a better solution long term.

Setting Up Storage Pool - Invalid Parameter

Hey all,
I've run in to an issue when trying to create a Storage Pool in Windows Server 2012 R2. I have two 4TB drives and I'm trying to create a pool out of them (intent is to Mirror), but when I've gone through the pool creation wizard I simply get the following
error:
"Could not create storage pool. Invalid Parameter"
Does anyone have any hints on where to start diagnosing this? Both drives are wiped, both drives can be pooled, and both have different uniqueIDs.
Thanks in advance!

Hi,
Which type of the physical disks are added to the Storage Pool? Are the virtual hard drives (VHDs) created by Windows Azure? If so, the physical disk size advertised by Azure VHDs is not compatible with Windows Server 2012 R2 Storage Spaces.
For more detailed information, you could refer to the thread below:
Error creating new Storage Pool in 2012R2 "invalid parameter"
If the Windws Server 2012 R2 is a virtual machine on Windows Azure, please also check if there is any error message in the Event Log.
Best Regards,
Mandy

Thanks for the reply,
The Windows Server 2012 R2 is on my own physical server and isn't virtualized. I'm simply trying to create a new storage pool from two physical HDD:s, the disks are Seagate 4TB disks. Both the disks are listed in the storage pool creation wizard. I checked
the Event Log also but there's nothing, the lack of proper error information is making this a bit challenging to figure out.
I've also tried using PowerShell to do the work:
New-StoragePool -FriendlyName POOL1 -StorageSubSystemFriendlyName (Get-StorageSubSystem).FriendlyName -PhysicalDisks (Get-PhysicalDisk -CanPool $true)

Can I set 10 GB memory to NTFS read cache like CSV cache, or Stroage Space SSD Tier on Windows Server 2012 R2 ?

Can I set 10 GB memory to NTFS read cache like CSV cache, or Stroage Space SSD Tier on Windows Server 2012 R2 ?
I want to use 10 GB memory to NTFS file system read cache for random read speed up.
CSV Volume have CSV Cache function,
Windows Server 2012 R2 Storage Space have SSD Tier function.

Hi Yoshihiro,
There is no build-in system function which support to setup memory as disk cache. I know some third party software support this so you could have a search with related keywords (memory, hard disk cache).
