Storage Pool - Add Physical Disk Window Empty

I have a storage space configured with 5 physical drives on a clustered pair of servers. The drives themselves are MPIO iSCSI targets that are attached to each server. When I try to add an additional drive to the pool, the window to add the drives is blank.
I know the drives will work in a storage pool because I've tested creating the pool with all drives from scratch.
Any idea why this window would be blank? (FYI, the error isn't related to the pool, its a server I need to remove from the all servers list)

Hi Delocx,
Please check whether the new added disk can display in disk management. If so, is there any volume created on the disk? It should be an unallowcated disk.
In addition, you can also run the windows powershell cmdlet Get-PhysicalDisk
to check the status of "can pool" is ture or false.
I hope this helps.

Storage Spaces - Remove Physical Disk from Simple layout

I am running Server 2012 RTM with a single storage pool containing 4 drives - 2.73TB, 1.36TB, 465GB and 148GB. There is a single virtual disk created, with thin provisioning, using the Simple layout, with a current maximum size of 2.73TB, and with 1.32TB
allocated. I want to remove the 148GB drive and replace it with a 465GB drive. When I right-click the 148GB disk and select Remove, I get a warning that Windows will attempt to rebuild any virtual disks that store data on the disk I'm trying to remove, and
that in order to succeed, the storage pool must have enough free space to accommodate the data from the disk I'm trying to remove. There is more than enough space in the virtual disk to accommodate whatever files may be stored on the 148GB disk - over 1TB
unallocated. However, when I confirm that I want to remove the disk from the pool, I get the following message:
This physical disk is used by one or more virtual disks that use the Simple (no resiliency) layout. To remove this physical disk, delete the following virtual disks: Simple
Surely the fact that it's a simple volume (rather than mirrored/parity) shouldn't affect the ability to move the data off the disk? It appears that disk removal is implemented as a simulated drive failure, forcing a rebuild of the resiliency data, rather
than by simply moving the data off the disk onto other available disks.
Additionally, after I've attempted to remove the disk, it's now been marked as 'Retired'.
Is there any simple way to remove this disk?

Same problem here, but I have some workaround for the problem.
But, even in Windows Home Server with its awesome disk extender (predecessor of Storage Spaces) you had to take the shares (meaning volumes in our case) offline so you could take out the disk from the pool.
Agree that it would make more sense to be able to remove disk from the pool online and the technology is most likely is already there: online cluster moves with defragmentation API was there for years and ReFS moves clusters online when it detects disk errors.
Anyway here is the process that may work for you if taking volume offline is an option in your case:
Try to remove physical disk in Server Manager - it will fail with abovementioned error, but the disk will go into "Retired" state.
Now provision a new Virtual Disk and a volume of your choice. Most likely you will pick the same disk and volume type as you already had, but this is the chance to change the topology. You should be able to do this since you have a lot of physical disk
space, especially if you used Thin provisioning.
It looks like at this point retired physical disk is not included into the new Virtual Disk provisioning, but it is still accessible via existing virtual disk.
Copy over all files from your old volume to a new volume.
Now delete old Virtual Disk.
If you want - change disk name and volume letter of new virtual disk that you created and new volume to what you had before.
Now in Disk Manager take failing physical disk offline.
Replace failing disk, initialize new disk and add it to the pool.
Note: for me sometimes removing disk in via Storage Pool management GUI does not mark it as "Retired". In this case you can open PowerShell as Admin and assuming you want to remove PhysicalDisk2 - run the following command:
Set-PhysicalDisk -FriendlyName PhysicalDisk2 -Usage Retired

Add Physical Disk to VM

Hyper-V 2012 R2. We have a SE3016 JBOD devices that hooked up to the physical server via SAS 6mbps HBA. On the physical server (2012 r2 core), diskpart lists the disk as offline. In hyper-v manager in the settings of the VM, i have added the hard drive via
scsi:
As you can see, the physical drive shows up in the settings. However, when i go into computer management of the VM, the drive is not listed there. The lights for the drive in the JBOD device is light-up and does not show any erros. I have rebooted the server
and JBOD device. Still no drive in computer management of the VM.
Am i doing this process right to get the VM to see the drive?

Hi Sir,
Unfortunately there is no JBOD at hand in my lab for reproduce this .
As I know , to take full advantage of JBOD you may try to use storage pool to create virtual disk then pass-through to VMs or store VM's vhd file :

How to create a local, non-clustered storage pool

Hello,
I have setup a two-node Failover Cluster, with a shared SAS DAS. So far so good.
One of the nodes also has internal disks that I wish to use for system backups.
This storage pool should not be clustered, as the disks cannot be seen from the other node. The trouble is that as soon as I create the pool it gets added to the cluster (in failed state).
In fact, the "Storage Pools" window in the server manager will only show me the "clustered storage spaces", with my internal disks in the Primordial pool.
Get-StorageSubSystem will show me both subsystems (Clustered Storage Space on ... + Storage Spaces on node-1) but fails to create a storage pool on the "local" subsystem.
How can I create a local, non clustered storage pool on internal disks ?
Cheers
alex

Hi,
SpackTime_ is right, the DA storage usually for the localdata backup, but if you want to use for remote computer backup, you can share a floder then you can storage your backup, but also that backup won't work the shared computer crash.

File CRC error on Read/Copy on NTFS on Parity Storage Pool

I can not figure out a way to resolve a CRC error while trying to Read/Copy a file that resides on NTFS on a Parity Storage Pool over 10 disks.
I would have figured that the Parity Pool would have caught the disk CRC error and healed the data with the Parity data. It doesn't.
XCopy does not work.
Robocopy does not work.
Cacls does not work.
Chkdsk /f does not find any errors.
Chkdsk /r /x does not find any errors.
fsutil repair file does not find any errors.
What am I missing? I thought Parity was supposed to protect me from a drive failure. In this case it isn't a complete drive failure, but the drive is reporting a failure.
Thanks,
Scott

I suspect it could be a drive problem.Can you run your hardware diagnostic tool and see if it reports any errors? There could be a predictive failure of one of the disk. Do you see any error event logs?
Thanks,
Umesh.S.K
Storage Space hides drives from any S.M.A.R.T. tools I have. The health status reported by the disk in the storage pool states Healthy. I would have to take down my server to do any disk specific diagnostics. Isn't this what Storage Spaces, Pools and Parity
was supposed to prevent.
No Disk errors in my event logs.
Do have any suggestions of hardware diagnostics that will not require me to take down the server, and also bypass the Windows Storage Pool Drive Hiding "feature?"

How to move a virtual disk's physical allocation within a Storage Pool

I have a pool of 3x500GB where one the physical drives is having intermittent issues. Currently, there is only one parity Virtual Disk of 300GB Fixed across 3 columns. I want to replace the bad drive with a good one. The old way (pre-2012) was replace the
disk, repair the RAID 5, resync and done. These basic steps are not working.
So far I have added a 4th 500GB drive to the pool. After searching and failing to find a way to move the data non-destructively, I decided to just pull the data cable on the disk I wanted to replace. After refresh/rescan, the disconnected drive shows "lost
communication" and the virtual disk (after trying to repair) shows "unknown" (but the volume on that disk is accessible in Explorer). When I try to remove the physical disk in Server Manager, I get "The selected physical disk cannot
be removed". Reading the error message, I see that the replacement disk cannot contain any part of a virtual disk. The replacement disk that I just added appears to have some space allocated (possibly because I have tried this same procedure a couple
of times already?). When I look at the parity disk properties/health, it shows all four physical disks under "physical disks in use".
I have deleted and recreated a lot of storage pools lately while trying to understand how they work but I would like to avoid that this time. The data on the virtual disk in question is highly deduplicated and it took quite a while to get it that way. Since
I can't find a way to copy/mirror the disk while keeping it fully deduplicated, I would need 3x the space to copy it all off, or a lot of time to load up and deduplicate a new virtual disk.
I have several questions:
1. How can a 3 column parity disk use parts of four physical disks? And can that be fixed without recreating the virtual disk?
2. When creating a virtual disk (for example a 3 column disk in a pool that has four or more physical drives), is there a way to specify which physical disks to use?
3. I understand that after a physical disk failure, the recovery process will move a virtual disk's allocation to a replacement disk, but can a virtual disk's allocation be moved manually among physical disks within the same storage pool
using a PS script?
4. Can a deduplicated virtual disk be moved/mirrored/backed up without expanding the data?
Any help is appreciated.

Im still fighting with storage pools and need more tests to be done and have a lot of questions my self but ther goes what I understood so far.
You may define physical disks used for virtual disk by Powershell ,
for list of all commands follow this:

specific command defining physical disks to be used on already existing virtual disk:

This example gets two physical disks that have already been added to the storage pool and designated as ManualSelect disks,
PhysicalDisk3 and PhysicalDisk4, and assigns them to the virtual disk

is there any thing do i have to do to make it work ??Check to see if the physical disk appears under the default volume group for your san. If not, refresh the san and wait until it does. Also, make sure you have an admin server configured for that san and that your Oracle VM servers are in the default access group.

Disks not avialable and cannot add new disks to existing pools

I have a few disks that are RAW and I want to add them to existing pools. However, only 1 disk shows up as a Primordial disk and the others do not. I cannot add these drives to a new volume and when I try to add any drive to an existing
pool, the add disk option is greyed out. I have search everywhere to resolve this but no luck.
What is interesting is one of the drives that shows available for a volume is the drive I have associated to backing up the OS on the server itself and is initialized, i.e. not RAW.

Hi,
Please try to run the following commands in PowerShell to obtain the information about disks:
Get-physicaldisk
Get-disk
In additional, the physical disk added to a storage pool must be 4GB or larger. If the space is less 4GB, the disk will not appear in the storage pool window.
For more information, please refer to the thread below:

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

Win 8.1 Storage Pool not allowing "add drive" nor allow expand capacity

Have one Storage Space within one Storage Pool (Parity mode) containing 4 identical hard drives.
Used for data storage, it appears to be functioning normally
and
has filled 88% of capacity
(ie. 88% x 2/3 of physical capacity (parity mode))
The only other storage on this new PC is an SSD used for OS (win 8.1 pro) and application software.
In "Manage Storage Spaces"
displays this warning message to add drives:
< Warning >
< Low capacity; add 3 drives >
After clicking "add drives", it displays:
"No drives that work with Storage Spaces are available. Make sure that the drives that you want to use are connected.".
However I had connected another two identical hard drives via SATA cables and "Disk Management" displays these two drives available.
in summary:
"Manage Storage Spaces" does not find these drives as available although they show correctly in Disk Management.
btw - I removed the pre-existing partitioning on the 'new' drives so now they show only as "unallocated" in "Disk Management". (I did
likewise before Storage Pool found the 4 original drives)
Perhaps the problem is to increase the total nominal capacity of the Storage Space, before can add more drives?
Microsoft says that the capacity of Storage Pools can be increased but cannot be decreased -
but computer displays no Change "button" by which this can be done. There is supposed to be a "Change" button but that is
not displaying for me. So "Manage Storage Spaces" offer me no option to manage the "size" of the pool.
only five options are displayed:
Create a storage space (ie. from the small amount remaining unused in the Pool)
Add drives (.... as explained already)
Rename pool (only renames the storage space)
Format (ie. re-format and so lose all current data)
Delete (ie. delete the storage space and so lose all current data)
using Google, find nothing bearing on this problem
except the most basic instructions to set up a storage space!
Can you help?
The problem is that the Storage Pool is not displaying a "button" to increase capacity, and when click "add drives" finds no hard drives available.

Hi,
I would suggest you launch Device Manager, then expand
Disk drives. Right-click the disk listed as "Disk drive", and select
Uninstall. On the Action menu, click Scan for hardware changes to reinstall the disk.
Please also take a look of this link:
see this part: How do I increase pool capacity?
http://social.technet.microsoft.com/wiki/contents/articles/11382.storage-spaces-frequently-asked-questions-faq.aspx#How_do_I_increase_pool_capacity
According to the link, to extend a parity space, the pool would need the appropriate number of columns available to accommodate the layout of the disk.

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 Storage Pool on Windows Server 2012R2 iSCSI target Storage Spaces - supported?

Hi,
for migration purpose we need more space for one of our DPM 2012R2 Servers.
And we cannot buy more space for our NetAPPs..
So our idea was to use an Windows Server 2012R2 as an iSCSI target and use Storage Spaces.
I remember something that using an iSCSI target on Windows 2008 was not supported.
Is this configuration supported when usinf DPM 2012R2 on Win 2012R2 and the target is Win2012R2 aswell?
Thanks in advance

Cannot add cluster disk on windows 2012

I have 2 servers connected to a shared storage array using Fibre Channel. Currently there are 2 luns on the storage device.
From the Failover Cluster Manager, when I select “Add Disk” from Storage – Disks, both luns show up and I can add them without problems. But if I choose to only
add one of them first (it doesn't make a difference which one is added first), then it will not allow adding the second one later. I get a message: "No disks suitable for cluster disks were found. For diagnostic information about disks available to the
cluster, use Validate a Configuration Wizard to run Storage tests."
When I do add one (or both disks at the same time), they work just fine for failover clustering.
I can’t imagine this is by design. Is this a known/unknown issue, or is there something special that needs to be done?
Thanks

Ok, no problem. I run the validation tests (Validate Cluster - Storage only) and I received the details shown below. I can clearly see that Cluster Validation tool does not find any disk suitable for 2012 cluster, and even I can see why (it is plain English).
Unfortunately this still does not explain how to fix the problem. Recommendations like "run Clear-ClusterDiskReservation PowerShell cmdlet to remove the Persistent Reservation from the disk" do not work - this discussion is available in another thread where
people having the same issue and no luck so far. I guess that I'm using old SAN (and I know that) that simply does not support SCSI-3 persistent reservation so those disks cannot be used in 2012 cluster. Oh well, will have to wait fro new SAN and then I can
play again...
Validation test results:
Physical disk with identifier {95059d50-a173-49bd-b029-fec326acd78c} has an existing Persistent Reservation placed on it, and will be removed from the validation set. This disk may already be clustered, on a different cluster or in use by another system.

No disks were found on which to perform cluster validation tests. To correct this, review the following possible causes:
* The disks are already clustered and currently Online in the cluster. When testing a working cluster, ensure that the disks that you want to test are Offline in the cluster.
* The disks are unsuitable for clustering. Boot volumes, system volumes, disks used for paging or dump files, etc., are examples of disks unsuitable for clustering.
* Review the "List Disks" test. Ensure that the disks you want to test are unmasked, that is, your masking or zoning does not prevent access to the disks. If the disks seem to be unmasked or zoned correctly but could not be tested, try restarting the servers
before running the validation tests again.
* The cluster does not use shared storage. A cluster must use a hardware solution based either on shared storage or on replication between nodes. If your solution is based on replication between nodes, you do not need to rerun Storage tests. Instead, work
with the provider of your replication solution to ensure that replicated copies of the cluster configuration database can be maintained across the nodes.
* The disks are Online in the cluster and are in maintenance mode. No disks were found on which to perform cluster validation tests.

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
