Hm... good feedback. Were you also running OCFS2 in dual master
mode, or master/slave?
Dual master. However, as I recall it, the performance issues were
present even when the other node was down.
ext3 is not a cluster file system such that a single network mount
can be safely accessible from multiple computers at once (cache
coherency, locking.) I've not used xfs, but I did not recall that
it is a cluster file system. Has that changed?
In our current setup, the filesystem is only used by a single active
node at a time.

I tried this configuration. I found that the active/active
configuration worked but had strange issues. These may have been
related to the stability of OCFS2 itself or it might have had to do
with running on a non supported OS (Fedora Core 5). I had strange
issues. Folders that would not delete, system would not reboot after
OCFS2 hang. I spoke with someone else who had similar issues getting
this type of system into production.
I would suggest having with the active/passive replicated disk
formatted with ext3 as a backup plan.

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?
