Please do not remove the cc-s.
Hard for me to comment without knowing anything about the panic.
However, assuming that the panic message indicated that the volume
needs to be fsck-ed. In that case, the best course is to umount the
volume on all nodes and running fsck on one node.

But initially the system had devices in /etf/fstab with _netdev

sometimes after few minuts.
The only way that I could start the system was mounting all
devices one by one, with a previups fsck.
I don't know if it is the better way, but is the only that I've
used succesfully.

Hello,
Is it possible to fsck a mounted filesystem. When one of
the cluster nodes reboots because a kernel panic, the
device requires fsck.ocfs2 because in mounted.ocfs2 -f
rebooted node is shown.
If mounted.ocfs2 -f shows the rebooted node, that means the
slotmap
has not been cleaned up as yet. That cleanup happens during node
recovery. If the volume is still mounted on another node, it
will get
cleaned up momentarily.
If however it does not get cleaned up, that means that the
volume is
not mounted on any node. In that case, the next mount will clean
up slotmap.
Either way one does not need to fsck just to cleanup the slotmap.
