Scenario
opensuse 15.5, the fs was originally created on an earlier opensuse
release. The failed file system is on top of a mdadm raid 5, where
other xfs file systems were also created, but only this one is having
issues. The others are doing fine.
xfs_repair and xfs_repair -L both fail:
Phase 6 - check inode connectivity...
- resetting contents of realtime bitmap and summary inodes
- traversing filesystem ...
- traversal finished ...
- moving disconnected inodes to lost+found ...
Phase 7 - verify and correct link counts...
- 16:15:34: verify and correct link counts - 42 of 42

fatal error -- File system metadata writeout failed, err=117. Re-run
xfs_repair.
I ran xfs_repair multiple times, but I always get the same error.
Is there any way to fix the above?
I tried xfs_db on an image file I created from the file system, and I
can see individual paths and file "good":
xfs_db> path /certainpath
xfs_db> ls
10 1550204032 directory 0x0000002e 1 . (good)
12 1024 directory 0x0000172e 2 .. (good)
25 1613125696 directory 0x99994f93 13 .AfterShotPro (good)
Is there a way to extract files from the file system image without
mounting the fs ? Or is there a way to mount the file system
regardless of its state?
Trying a regular mount, with or withour -o norecovery, I get:
mount: /mnt: mount(2) system call failed: Structure needs cleaning.
Regards.
