XFS internal error xfs_iformat(realtime) even after xfs_repair.

[Ajeet Yadav <ajeet.yadav.77@xxxxxxxxx>]

Kernel: 2.6.30.9, XFS backported from 2.6.34, xfsprogs-3.0.5

 

I used a script

1. create some file, directories, symlinks

2. unmount the file system

3. run xfs_bd with blocktrash

4. xfs_xfsrepair -L

5. list "ls -lR"

6. remove all file and directory "rm -rf *

 

Often during testing I get the below backtrace from kernel during ls, rm even though I already run xfs_repair on it.

Is it related to xfsrepair or xfs ?. I think xfs_repair must have detected this problem and corrected it.

 

There is similar problem already reported by

xfs_repair log

-------------------

xfs_repair -L /dev/sda1
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
        - 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
