Can someone give pointers to integrating ocfs2 with heartbeat? The idea
is to run ocfs2 as the cluster file system on the real servers running
on an iscsi failover backend cluster. Apparently some userspace patches
are required to ocfs2 to let hb manage it, but I think things have
changed much since most of the information I've found with google was
published.
ocfs2 seems to be the best available cluster file system to run with
hb. The gfs file system is perhaps the most complete, but it is all
entangled with the redhat clvm and cluster management, and I do not want
to manage that. Does anyone have a better suggestion than ocfs2?
as noted by other ppl, we too experienced a major performance hit when
using ocfs2 over ext3/xfs. moreover, we too experienced those strange
issues with creating/deleting files and/or folders. unmount/mount
usually makes those issues go away.
the problem with ocfs2 is, that it has its own "heartbeat". so if node1
goes down unexpectedly, ocfs2 fences node2 thus crashing the whole
cluster.
to my knowledge, the folks from suse made some heavy modification
to ocfs2 to remove this behavior. i once tried to incorporate their
patches into the then current vanilla kernel, but failed mainly because
of my lack of time.
if any1 is interessted in helping me, i would go back to this issue
and retry to patch ocfs2. otherwise, i think the better way would be to
use drbd+ext3/xfs+nfs server.
any opinions?
cheers,
raoul
