Hi,
The two files in the root directory of a 500GB external USB HDD
became corrupt,
probably due to a power failure.
dave@K-Matrix $ ls -l /media/Galaxy/
ls: cannot access /media/Galaxy/ChnSchld_pre_4-14.tgz: No such file
or directory
ls: cannot access /media/Galaxy/dhr820xu.ext: No such file or
directory
total 24
?????????? ? ? ? ? ?
ChnSchld_pre_4-14.tgz
?????????? ? ? ? ? ? dhr820xu.ext

xfs_repair didn't help much; it just removed the two filenames.
At minimum, I expected two entries in L+F but the L+F directory was
not created.
dave@K-Matrix $ sudo xfs_repair /dev/sdc1
Phase 1 - find and verify superblock...
Phase 2 - using internal log
- zero log...
- scan filesystem freespace and inode maps...
- found root inode chunk
Phase 3 - for each AG...
- scan and clear agi unlinked lists...
- process known inodes and perform inode discovery...
- agno = 0
- agno = 1
- agno = 2
- agno = 3
- process newly discovered inodes...
Phase 4 - check for duplicate blocks...
- setting up duplicate extent list...
- check for inodes claiming duplicate blocks...
- agno = 0
entry "ChnSchld_pre_4-14.tgz" in shortform directory 128 references
free inode 48145461
junking entry "ChnSchld_pre_4-14.tgz" in directory inode 128
entry "dhr820xu.ext" in shortform directory 128 references free
inode 48145451
junking entry "dhr820xu.ext" in directory inode 128
- agno = 1
- agno = 2
- agno = 3
Phase 5 - rebuild AG headers and trees...
- reset superblock...
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...
done
