[Linux-cluster] kernel panic - help!

[German Staltari]

Hi, we have a 6 node cluster with FC4, kernel 2.6.16 and the last stable 
cluster tarball. The cluster was OK until we had a little SAN failure, 
since then, the cluster (entirely) is getting kernel panic. This is the 
dump:

qmail-be-04 kernel: ------------[ cut here ]------------
qmail-be-04 kernel: kernel BUG at 
/soft/kernel/cluster-1.02.00/gfs-kernel/src/dlm/lock.c:357!

All nodes dies at the same time with this kernel panic.
Thanks
