Here is the setup:
It's a JBOD with Volume size 20 GB. The directories are empty and this
is basically continuous copy of the file on all thirty directories.
surprisingly none of the copy succeeds. All the copy processes are in

With the prep. As mentioned it is with 2.6.24 Fedora kernel.
It would probably be best to try a 2.6.26 kernel from rawhide to be sure
you're closest to the bleeding edge.
<Sagar> Sure Eric but I reran the test and I got similar errors with
2.6.24 kernel on x86. I am still confused with the results that I see on
2.6.24 kernel on x86 machine. I see that the used size shown by ls is
way too huge than the actual size. Here is the log of the system
[root@lab00 ~/test_partition]# ls -lSah

It'd be great if you provided these actual scripts so we don't have to
guess at what you're doing or work backwards from the repair output :)
Attaching the scripts with this mail.
Not really. That's why it was surprising. Even after setting the
error_level to 11
dmesg log doesn't give any information. Here is XFS related
XFS mounting filesystem loop0
Ending clean XFS mount for filesystem: loop0
Which is basically for mounting XFS cleanly. But there is no exception
and nothing else of interest either?
There was no failure. Only the processes were stalled. System was
Filesystem has become completely sluggish and response time is increased
3-4 minutes for every command. Not a single copy is complete and all
the copy processes are sleeping continuously.
And how did you recover from this; did you power-cycle the box?
