Before you go slapping redhat around I think you should start checking what
being done and why. If you are running a cluster, it's your responsebility to

To answer your question about clustering, the newer clusterring and GFS
packages use the
same underlying subsystems. It's that simple.
It's done that way to ensure a constant view of "clustered" parts, get
etc. Then RHEL 3 way of doing clusters is no more and with good reason. If
don't talk to each other, they tend to step on each other.
That all said, it would be nice if GFS/Cluster updates did come out at or
around the same
time as kernel updates. I do not use up2date and cannot in my situation so
do it for me. That's ok tho cuz I like to know whats happening on my

of much less

Just my 01 cents...

I just ran an up2date on some servers in a RHEL 4 ES cluster, and the kernel
was updated. Now, I tried rebooting one of the nodes in the cluster, and at
least one of the cluster management software daemons didn't properly start,
seemingly due to kernel module mismatches.
Reverting to the older kernel made the cluster node join the cluster again.
This is not impressive; it's actually very disappointing. Red Hat, please
By the way: Why are special kernel modules even needed by the cluster
software if GFS isn't used?
