[Ocfs2-users] Big load and many error with ocfs2 1.3.3

[Cyril FERAUDET]

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
