Hi all,

Not sure if this is the appropriate forum to reports xfs_repair bugs? If wrong, please point me in the appropriate direction?

I have a corrupted XFS volume which mounts fine, but xfs_repair is unable to repair it and volume eventually shuts down due to metadata corruption if writes are performed.

Originally I used xfs_repair from CentOS 8.1.1911, but cloned latest xfs_repair from git://git.kernel.org/pub/scm/fs/xfs/xfsprogs-dev.git (Today, Feb 9th, reports as version 5.4.0)

releasing dirty buffer (bulk) to free list!

 

Does not matter how many times, I've lost count, I re-run xfs_repair, with, or without -d, it never does repair the volume.
Volume is a ~12GB LV build using 4x 4TB disks in RAID 5 using a 3Ware 9690SA controller. 


Any suggestions or additional data I can provide?
