I currently have several machines I'm about to cluster using RHCS,
utilizing shared storage (XRAID w/ GFS). I currently have another
existing XRAID which is mounted on one machine. I need to move all
this data from this existing XRAID to the new GFS XRAID. Right now, I

Hi everyone!
How about this RedHat ClusterSuite 5.1 configuration, if i have example 2 nodes
test1 and test2:

test2 ip=10.10.10.6
Private Heartbeat network

yeah iozone -a is pretty easy. For anyone who's interested: some graphs from
results I got a couple weeks ago while running it on 5 nodes at once:

Update for anyone watching :).
I've eliminated GFS as being the slowdown at least. No ideas on the DLM
problems but I'll get back to that after I figure out the slowdown.
Seems that the storage controller has problems so I'll either change out the
chassis or controllers if I can. Once I nuke th

I'm still getting very long delays before access. Is there some way of testing
this to see if it's the storage or the GFS setup? Like a test I could run with
the storage connected raw then with GFS?
Perhaps I just kill the partition, run some test, format it as GFS again,
mount it, test?

Respected Users
I have a problem in cluster. One user of this cluster needs huge
amount of space. In this cluster one big partition(size 1TB) is
mounted on /data . So I provide this amount of space for his program
execution. At 1.30 PM he occupied 200GB of this storage(which is
