Hello Sunil,
Just back of holidays, I tested the 2.6.22 with all of your patches.
No problem instead of without patches, put aside that I suspect a
locking problem.
Indeed, I've a script who replace a file with an flock (LOCK_EX) on
the shared volume and
an other script who acces to the shared volume by NFS to copy this
file to a local volume.
This file is copied each minutes and regulary I've an empty or
truncated file.
Do you now a restriction about locking or something like that ?
Thanks for all.
Cyril

Sorry I don't track the debian kernel. But typically they take
the source for kernel.org and use it as is. But don't take my
word for it.

There is actualy only one node who export the ocfs2 volume via NFS

I've got no problem until I leave it alone. When I add an other
node I got the error below.
So if I understand the 2.6.22 provided by Debian haven't all
patches listed below and
would be the cause of the truncated file of my ( a bad day to fix
it ;-) ) ?
Can I apply the missing patches to the debian package or I need to
use a fresh sources ?
Thanks in advance.

It should be fixed in 2.6.22.
Use 2.6.22 + patches as listed in the following link:

A response to my self ...
Thanks Sunil Mushran, I haven't see your response in the
thousand of mail at my return of holidays ...
This patch seems to be in the 2.6.20.
Can this error cause my big load average ?
No other patch was included till the 2.6.22. Some one have the
same problem than me with the 2.6.22 (file truncated) ?
Thanks,
Cyril

Hi all,
I've one 3.5T Xserve with one LUN shared between 7 debian nodes :

some minute of utilization I get these error :

Then all node have a huge load more than 100 with more than 50%
of iowait.
I've tested the kernel 2.6.22 (don't remember the ocfs
version), there are no ocfs2 error, but all opened to write
file are truncated to zero size !
Have you an idea, do you know a stable version of ocfs2 build
into a debian kernel ?
Thanks,
Cyril
