[Linux-cluster] really reliable?

[Ryan Golhar]

Hi all,

Is redhat cluster suite really reliable?  I've been having so much 
trouble getting a cluster up and running, I'm beginning to second guess 
my decision to use this software stack.

I have 3 nodes (eventually 10) running and set up.  The fencing method 
is by a brocade fibre switch.  The ultimate goal of this cluster is to 
shared a SAN connected by fibre.

I've installed just the bare minimum (before even getting to GFS) to 
test the cluster software.  Just starting cman cluster services fails on 
two of the nodes.

Even when I try to reboot the nodes, I can't because the whole system 
hangs on various processes that don't ever shut down.  I have to 
physically reboot these boxes.

The logs fill up with errors about not being able to connect to cman, etc.

I've been at it for awhile now and am not sure this is the best route 
anymore.
