I've been using bonnie++ off and on for a long time. Suddenly, it has
started failing when run against an XFS filesystem situated on a SATA
drive. Here's the output of a run:
$ bench/sbin/bonnie++ -m "Luther 2.6.17-rc1 XFS SATA" \
> -d /archive/bench \
> -s 3008 \
> -n 1024 >> bonnie.out 2>> bonnie.err
Version: 1.03

Delete files in sequential order...Bonnie: drastic I/O error (rmdir):
Directory not empty
Cleaning up test directory after error.
This is on a 2.6.17-rc1 Linux kernel. The interesting thing
is that not even root cannot delete the directory in which
bonnie++ is working:
[~]$ ls -ld /archive/bench/Bonnie.8426/
drwx------ 2 kwall users 4096 2006-04-05 09:06 /archive/bench/Bonnie.8426/
[~]$ ls -al /archive/bench/Bonnie.8426/
total 24
drwx------ 2 kwall users 4096 2006-04-05 09:06 ./
drwxr-xr-x 4 kwall users 42 2006-04-05 06:24 ../
[~]$ sudo rm -rf /archive/bench/Bonnie.8426
rm: cannot remove directory `/archive/bench/Bonnie.8426': Directory not
empty
As you can see, the directory is empty, but a "rm" fails (as does
"rmdir"). I'm retesting with a 2.6.16 kernel as I type. It isn't
clear if the problems is XFS, some other piece of the kernel, or
bonnie++. Neither dmesg nor syslog shows anything amiss. I suppose
I could strace the run, but I'm not especially eager to deal with
a multi-gigabyte output file if there is a more focused method to
isolate the problem.
I've also written to bonnie++'s author.
Thanks for the help.
Best regards,
Kurt

See if 2.6.16.1 fails too for starters then we'll take it from there.
cheers.

Lemme answer that for you - "no". I've reproduced the problem,
I'll get back to you once I've nutted out whats gone wrong.
Thanks for reporting it.
cheers.

Me too.
2.6.16
I had filesystem corruption and needed ran xfs_repair.
After I finished I removed most of the lost and found bits but was left
with:
haze:/scratch/lost+found# ll
total 28
drwxr-xr-x 4 root root 38 2006-04-02 08:29 ./

Obviously I had an fs corruption (due to raid failure due to some bogus
libata errors) so this may not be the same thing.
