Re: need help how to debug xfs crash issue xfs_iunlink_remove: xfs_inotobp() returned error 22

[符永涛 <yongtaofu@xxxxxxxxx>]

The servers are back to service now and It's hard to run xfs_repair. It always happen bellow is the xfs_repair log when it happens on another server several days ago.
 -sh-4.1$ sudo xfs_repair -n /dev/glustervg/glusterlv
Phase 1 - find and verify superblock…
Phase 2 - using internal log
        - scan filesystem freespace and inode maps…

So this happens reliably, but infrequently? (only every 2 weeks or so?)

Can you provoke it any more often?

That's a RHEL6 kernel; I'm assuming that this is a RHEL clone w/o RH support?

I agree with Ben that I'd like to see xfs_repair output.

Since the fs has shut down, you should unmount, remount, and unmount
again to replay the dirty log.  Then do xfs_repair -n, and provide the output
if it discovers any errors.

Thanks,
