Public bug reported:
When trying to delete an empty directory on a btrfs partition I'm
getting the following error:
r...@ceph-mds:~# rm -rf /data/old/
rm: cannot remove `/data/old/broken': Directory not empty
However:
r...@ceph-mds:~# ls -la /data/old/broken/
total 0
drwxr-xr-x 1 root root 0 2010-08-26 07:29 .
drwxr-xr-x 1 root root 12 2010-08-26 22:10 ..
Also, I don't fully understand why rm -rf would care about non-empty
directories.
I've since upgraded the kernel twice with the maverick updates, so I
also rebooted twice, no change. So it's not some file that was deleted
but is still opened by some process. I've tried btrfsck, but that didn't
complain either.
Currently trying if I can reproduce this on another machine.
Unfortunately /data simply is part of the / partition, so reformatting
would be a bit annoying. Can do if needed, of course.
