When i attempt to run Bonnie on my xfs filesystem, it crashes 3/4's way
thru on writing the 100MB benchmarking
The fs driver/process would stop at the "Writing intelligently..."
process. At this point, trying to 'kill <process>' wouldn't work and
niether would umounting the drive would work...resulting in an unclean
reboot & me loosing more of my .configrc files :-( ... very bad.
I'm also seeing similar activity when writing agressively to a XFS
partition and then having another process also try writing at the same
time. results a hang in the process (again) and unable to umount the
drive.
I believe not even the 'kernel hacking' keys work.
Here's the process i use on a system hang:
alt+sysreq+s = sync all drives now!
alt+sysreq+u = umount all mount points now!
alt+sysreq+b = reboot system now!
Bonnie++ == Supposedly a better benchmarking utility then hdparm -tT
http://sourceforge.net/projects/bonnie/
Although, I was able to successfully use bonnie on a ext3 partition tho
on the same computer:
$ bonnie -d /extra1/
File '/extra1//Bonnie.2698', size: 104857600
