[Ocfs2-users] can't mount device

[Christophe BOUDER]

Hello,
i'm running ocfs2 on 27 nodes
with 2 devices ( 2 fiber channel disk array  storage)
on debian system
vanilla kernel 2.6.38.2
ocfs2-tools    1.6.3-1

sometimes when i want to mount the device1
after a reboot i can't :

 (mount.ocfs2,9543,2):dlm_join_domain:1857 Timed out joining dlm domain
EA9679D689F64044BFBCDF0D2F7BCDF0 after 94000 msecs


the other nodes have already mounted device1
and have heavy I/O access on it.
The node which want to mount device1 have already mounted device2.

any help welcome.
thank you.

see the file o2cb.

cat /etc/default/o2cb
