PowerEdge T420 - After power outage-cant access a Raid 5 disk - Volumerepaire was not succesful

Hi,

Sorry to hear that. The PERC you having doesn't have battery-backed cache, so filesystem corruption after a power outage isn't surprising. Please take a look Logs or alerts tab. Is there any informational ones? You can do consistency check like inthis article  But I think your disks and Virtual Disk morelikely okay. But on OS side you may need to check somethings. For example you can check CheckDisk on the Windows And a backup link for CHKDSK

Hope that helps!

Dear Erman, I have already done consistency check yesterday, which succeeded, then rebooted but it did not help. 

I tried Checkdisk as follows 

chkdsk /F /R E:

I got the following response

The type of the file system is REFS.
The ReFS file system does not need to be checked.

and from explorer I get

Thank you for your feedback. I think you need to do something on the OS side. I mean I have limited access to OS regarding issues but I would do try reassign a Drive letter if it possible on Disk Management. And try to that

• Open PowerShell as Administrator.
• Try: Repair-Volume -DriveLetter E -OfflineScanAndFix

I tried but it is failing as follows

PS C:\Users\salam> Repair-Volume -DriveLetter E -OfflineScanAndFix
Repair-Volume : The repair failed

sorry to hear that then unfortunately I'm stucked at this point. I think If the volume is badly corrupted, Repair-Volume might not be able to fix it. That error usually means the damage is beyond what Windows can handle on its own you’ll likely need to use third-party recovery tools or take a more manual approach to get the data back.

@DELL-Erman O​ OK, can you please suggest a tool please as this is the 1st time I see this issue.

@DELL-Erman O​ Also, I would like to mention that I have backups for all data on the raid 5 volume, if I do reconfigure or rebuild, might this help? Does this operation delete the data? and should I do it in OpenManage or at boot?

Hello,

I am limited too, as Erman, on the OS repair tools. Maybe a Microsoft forum could help.

Since you have a backup then you may be able to do the following:

You could delete the array

Swap the drives around to other slots :   [2 to 3],   [ 3 to 4],   [4 to 2]

Recreate the RAID5 and do Full Initialization

Restore data from backup.

You can do that at the controller BIOS level or with OpenManager Server Administrator if you have that installed.

Thanks for all, I ended by deleting the array, recreating it and restoring the data.

Thanks for your feedback. I hope everything goes well.
