If you see almost simultaneous kernel panic on all cluster nodes, then you probably hit the same bug (or feature? ;) ). I tried GFS2 as well, it also had one grave bug (under high load) but that one is fixed in all fedoras after 13 I hope and hopefully in el6 too. You can search redhat bugzilla for bug I opened about that. Right now I do not use any of them, but plan to return to GFS2 after some time. >From what I saw, OCFS2 is (was) much faster (up to 10 times) then GFS2 in almost all use cases. But when it comes to stability, it is absolutely unusable (for me). For other filesystems - I do not know any competing to that two above (non-distributed clustered fs on a shared/mirrored block device). You may look at lustre, GPFS, pvfs, ceph, but they are completely different (distributed) and wont probably fit your storage design. Also they all have drawbacks: lustre is available only for el5 (afaik), GPFS is not free, ceph is still alpha-quality and not recommended for production.
