Hello all, Some time ago I set up Storage Spaces in Windows 8.1 x64 in a parity setup. Originally I had six 3TB drives and was running low on space so I decided to add an additional two 3TB drives I had laying around. One of the drives added successfully, but the other one refuses to add to the storage space. The error windows gives me is a 0x0000002 "The system cannot find the file specified." I am connecting the drives via a RocketRaid 2760a RAID card, and all drives are the same model. Some troubleshooting I've already attempted:

• sfc /scannow returns no errors
• chkdsk came back clean on the storage pool as well
• Reordering the drives on the raid card
  • I've noticed that if the drive that is not part of the pool is in a higher channel than the drives that are, it causes windows to think that there is no storage space configured.
• Adding the drive connected to the motherboard via SATA (this succeeds without issue) and then reconnecting it via the RAID card (it doesn't recognize it as the same drive and doesn't include it in the storage space)
• Trying to add the drive via powershell
  • The 7 disks already in the pool are listed correctly when using the "get-physicaldisk" command, but the disk I am trying to add is not, but it is listed when using the "get-disk" command

Does anyone have any ideas, or suggestions for further troubleshooting steps? Thanks!

Hello BetterWithBacon,

Based on my test, I create 8 5GB VHDs.
I create a storage space with 5 VHDs, and then I can normally add the rest of the VHDs one by one.

I suggest you to contact the manufacturer of RAID card to confirm if there are misconfiguration in the RAID.

Fangzhou,

Is there anything specific that could be misconfigured that would cause this issue?  I ask because the OS sees the drive normally and can format and use it as it's own drive without issue, which seems like the RAID card doing it's job.  It's hard to ask HighPoint support for help when I can't give them anything the RAID card is doing wrong.

Hello BetterWithBacon

Please correct me if I have misunderstanding.

As you mentioned, you can normally connect the drive to the motherboard, but the RAID card doesnt recognize it as the same drive.

So I think the drive is OK, and you need to check the RAID.

Fangzhou,

Not quite. If I connect the drive to the RAID card and then format the drive, I can use the drive normally within windows as any other disk.  The problem is that I cannot add the drive to the storage space when it is connected to the RAID card.

Hello BetterWithBacon,

The Windows can recognize all the drivers in the RAID cards, but the storage space wizard cant add  one of them?

I still suggest you to contact the RAID card support, because based on my test without a RAID, the storage space works normally.

Best regards,
Fangzho

Fangzhou,

That is correct.  Windows recognizes all the drives on the RAID card but the storage space wizard will not add the 8th drive to the parity space.  

Perhaps you can answer me as to why the 8th disk is not listed when using the "Get-PhysicalDisk" command in powershell, but the other 7 disks are.
