Storage Spaces Issue

rojones · 4 Jan 2018 at 12:09

After some advice.

I had a windows storage space setup with 4 x 2TB drives in Parity mode. For some reason the other day it went offline and simply says "Error Offline due to critical write failures; add drives"

Now i tried to 1st simply bring it back online (which basically does nothing, just fails) so then i added another drive to it which again hasn't resulted in any ability to bring back online. I have ran a tool from the Western Digital site "Data Lifeguard Diagnostics" and ran the advanced check on all 4 drives that were originally in the storage space setup and all come back healthy.

I guess i am simply thinking at this point, is there anyway i can force this online to simply read and backup the data and nuke the setup and rebuild if necessary. Bit of a loss as to what to do next.

Cheers

What are you running this storage space from? NAS? SERVER? OS?

Have you tried booting with a linux live USB and see if you can mount the hdd's in that?

Remove it, remake it, restore from your backup.

Windows 10 OS in a HP microServer. Yeh had a bad feeling about the from backup. Ive got a backup of the important stuff but kinda hopefully i could get the rest back. Bloody storage space a load of pap then. It would supposed to support a disk failure (which none have apparently) yet its toast. I did just run the free get data back and it managed to scan the virtual volume and i could see my directory structure. So maybe some hope there. Will have to purchase a copy that allows restore.

Wont be going back to Storage Spaces in a hurry after this experience. I had 2 External NAS bays before and were rock solid for years and years.

A post on Microsoft's forums suggests you can bring it back online read-only with the following Powershell command (run as admin). You'll need to get your virtual disk ID either from the event viewer or maybe running the Get-VirtualDisk command.

Code:

Source: StorageSpaces-Driver
Event ID: 312
Virtual disk {353523d0-ee91-11e2-be7c-bc5ff4b0cdb7} has failed a write operation to all its copies.                
                
You can online the disk by using the following commands in PowerShell:                
                
Get-VirtualDisk | ?{ $_.ObjectId -Match "{353523d0-ee91-11e2-be7c-bc5ff4b0cdb7}" } | Get-Disk | Set-Disk -IsReadOnly $false
Get-VirtualDisk | ?{ $_.ObjectId -Match "{353523d0-ee91-11e2-be7c-bc5ff4b0cdb7}" } | Get-Disk | Set-Disk -IsOffline  $false

Thanks Andshrew yeh i managed to get it online last night with a different command in read only mode. So gonna buy another External drive tonight to back it all up and then nuke it. Really has killed all confidence in storage spaces for me. Going to have to think of another way to run this setup. My HP Gen8 obviously doesn't support a hardware version of Raid 5 (without a £200 addon card) which is what i was kind of aiming for (despite the poor performance in storage spaces, which wasn't an issue for me)
