I hit this corruption again today with 4.10-rc2 kernel & latest master
branch of xfsprogs, still ppc64le host.
*** xfs_repair -n output ***
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 (but don't clear) agi unlinked lists...
- process known inodes and perform inode discovery...
- agno = 0
attribute entry #0 in attr block 0, inode 10236 is INCOMPLETE
problem with attribute contents in inode 10236
would clear attr fork
bad nblocks 10 for inode 10236, would reset to 0
bad anextents 1 for inode 10236, would reset to 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
- agno = 2
- agno = 3
- agno = 1
No modify flag set, skipping phase 5
Phase 6 - check inode connectivity...
- traversing filesystem ...
- traversal finished ...
- moving disconnected inodes to lost+found ...
Phase 7 - verify link counts...
No modify flag set, skipping filesystem flush and exiting.

I attached compressed xfs-181.full file, in case someone has interest to
look into it.
Thanks,
