Hi Sunil,
Below you will find the result of the command "$ ps -e -o
pid,stat,comm,wchan=WIDE-WCHAN-COLUMN" ran 6 times with more or less 10
sec. delay.
Now, from my point of view, I have a load of 8.00 and nfsd is running 8
instances witch are all in the "D" state. I am kind of making links here
;) What does the "ocfs2_wait_for_mask" means? Is there some problems
with OCFS2 and NFS? (NFS is somehow not a perfect FS)
Thanks
