I did a check on Disk5 such as suggested in the link by running the check with repair (option -nd). Below the xfs_repair_status :
Phase 1 - find and verify superblock...
- block cache size set to 738272 entries
Phase 2 - using internal log
- zero log...
zero_log: head block 16739 tail block 16733
ALERT: The filesystem has valuable metadata changes in a log which is being
ignored because the -n option was used. Expect spurious inconsistencies
which may be resolved by first mounting the filesystem to replay the log.
- scan filesystem freespace and inode maps...

No modify flag set, skipping phase 5
Inode allocation btrees are too corrupted, skipping phases 6 and 7
Maximum metadata LSN (2130140933:-29345724) is ahead of log (1:16739).
Would format log to cycle 2130140936.
No modify flag set, skipping filesystem flush and exiting.
