Yesterday it crashed on one of machines (running 4.8.11)

-------------------------
I have scheduled repair on today, all these blocks were repaired using xfsprogs 4.9.0
Kernel is now 4.8.15
-------------------------
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

- process newly discovered inodes...
Phase 4 - check for duplicate blocks...
- setting up duplicate extent list...
- check for inodes claiming duplicate blocks...
- agno = 0
- agno = 1
bad attribute format 1 in inode 1074268922, resetting value
bad attribute format 1 in inode 1077334032, resetting value
bad attribute format 1 in inode 1093437859, resetting value
- agno = 2
bad attribute format 1 in inode 2147673775, resetting value
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
-------------------------
Thank you very much for patch, it has done it's work
