After latest startup, Disk 4 of my 6 drive array (5 x 8TB ironwolf and 1 x 4 TB ironwolf) was shown to be Unmountable: Unsupported or no file system.  I thought it might be a bad cable so I changed the cable out with no change.  At that point I was at a loss so I tried moving to another slot to see if I could ascertain if the drive might be bad.  At some point, I also received a Red X on one of my two parity drives ( 2 x 12 TB).

 

I am at a loss where to go or what to do.  I have attached the diagnostics file and thank you in advance for any advice/help.

Check filesystem for disk4, run it without -n

Ran the check and got this:

 

Phase 1 - find and verify superblock... Phase 2 - using internal log - zero log... ERROR: The filesystem has valuable metadata changes in a log which needs to be replayed. Mount the filesystem to replay the log, and unmount it before re-running xfs_repair. If you are unable to mount the filesystem, then use the -L option to destroy the log and attempt a repair. Note that destroying the log may cause corruption -- please attempt a mount of the filesystem before doing this.

 

I retried to mount Disk 4 by stopping the array in Maintenance mode and restarting the array but Disk 4 still was unmountable.

 

I assume I should run the Disk check with -L now.

Yes (and without -n).    After that the drive should mount when you restart in normal mode.

OK.  Assuming all goes well with Disk 4, what should I do about the parity drive ( i have two) that has the red x.  To be clear only one of the parity drives has the red x.

All went well.  Do I do anything about the Parity drive with red x?

 

Hey I found your instructions for another user about this and used the following:

thanks for the help and I will mark this as solved in about 24 hours after the parity drive rebuild.
