No I do not but if you elaborate on the tests performed or have atest 
script I would be glad run some bench marks.

It would also be helpful to know the hardware you are running on.

Hi Dan,
 
Have you got any performance figures on the OCFS2 ? 
 
My GFS is currently delivering the following performance:
(2 nodes, 2gbit FC HBAs multipath'ed + 1 Fujitsu SAN (SX60) 7x250gb raid 
5.)
 
Writes: average 100mb/sec, 200 files/sec (with simple cp/rm)
Writes: max 150mb/sec, 250files/sec (with simple cp/rm)
Reads: average 160mb/sec (cat > dev/null - uncached)
Reads: average 1150mb/sec (cat > dev/null - cached)
Anybody have a feeling about this performance level?
 
Regards
Kristoffer

Ok Here is what I did to get it working: 

used RHCS to manage the cluster services 
used CLVM  to manage the LVM metadata across cluster 
        Coded a "locking_type = 3" in the LVM.CONF file 

Used OCFS2 to cluster and manage the filesystems across cluster. 

Configuration is 

2 node cluster runing nfs 

vitural IPAddr service to allow clients to mount the drives via NFS 

All appears to be working fine. I can fail over the services manually or 
even boot a server and the failover works great. 

Now the big question....is this supported by redhat and oracle ...hmmmm 


Thanks to all who helped get this working...
