Two disks dropped offline

Featured Replies

I had two drives fall offline recently. Disk 1 is showing up after a reboot, disk two must be rebuilt (which I'm doing now) disk 1 extended smart test showed no errors. I had one spare sata cable and replaced the for for disk 1 just in case that was the issue, I'm going to replace the one for disk 2 ASAP. just seeing if anyone has any insight. 

 

Thanks in advance!

Emulated disk2 is not mounting, before rebuilding check filesystem, run it without -n

xfs_repair status:

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.

Should be resolved, see if it mounts now and contents look correct.
