Hi Ben
Thanks a ton for below information. But I have doubt on cluster.conf
file snippet below -
Here for "node1
Thanks for responding, Joel. It turned out to be a VLAN change which required a
change with the bonded NIC. Immediately after issuing
ifenslave -c bond-hb eth2
on the problem node, it joined the cluster and the OCFS volumes could be
mounted.

So I just started setting up a RHEL6 box for use in a load balanced
cluster and have run across a problem. The way you set up a virtual IP
on the back end realhost side is to add an interface alias to the
loopback device (such as lo:0). Well the ifup-eth script in RHEL6
refuses to add aliases t

You certainly should be able to. You should not need a reboot
either if you just want to rejoin.

We'd need to know how your storage is configured.
Everything from how storage is connected to the system (if it's
external) or if you're using an internal RAID controller. What sort of
mirroring are you using, how many locally connected HDD drives do you
have, how are the clustered file system

I apologize now for being blunt;
None of that matters. Wha
It is not only data, it is like the system were booting from a 4 years
time configuration as everything that we have done, included other kind
of configuration files, just disappeared!!!

Luis,
You still haven't provided the relevant details of your configuration.
The df output you provided isn't relevant in terms of the data recovery.
You haven't even mentioned what file system the lost data was on.
You mention mirroring - what was doing the mirroring? Hardware RAID?

Well, there are not backups of that valuable lost data but the cluster
was using disk mirroring but no one has a clue of how to take advantage
of that. Nobody here is a cluster expert and that has been the problem I
guess.
We haven't really "touch" any important system file, after physically

In fact, it's a benefit because, last I checked, snapshot'ing of

and it still isn't. i tried to slapshot a gfs2 volume and it refused,

This is my method. However, note that stopping GFS unmounts the volumes,
so you can skip the manual unmount.

What is the current recommendation concerning shutting down a cluster node?
Is it acceptable to use shutdown or init to reboot an active/running cluster
node?
I have reviewed the RHCS admin guide and it does not state to *not* use
shutdown or init.
RHCS RH436 training manual (page 305) says th
Q: Can I reboot one node in a two-node cluster and have it rejoin the cluster?
I've a two-node cluster which recently had HBAs replaced on both cluster nodes.
Node 1 was ejected sometime after its latest reboot, and now won't mount its
OCFS volumes. The volumes' headers are verified from n1, i.e.

The reason I am asking is, as a part of RHCS there are various
