[ClusterLabs] Fwd: Rebuild of failed node

[Fabrizio Ermini]

Hi all! Freshmen here, just joined.

I'm currently in the need to rebuild a failed node on a
pacemaker2.1/corosync3.1 2-node cluster with drbd storage.
I've searched in Pacemaker docs and in the list archives, but I haven't
found a clear guide on how to proceed in this task. So far, I've
reinstalled a new server, configured the same IPs (it's a 3-ring cluster)
and hostname of the failed one, and installed all the software. I've also
fixed DRBD layer and started the resync of the volumes. But it's not clear
to me how to proceed - I've found some hints online pointing to the need of
manually copying corosync config, but they were quite old and probably
obsolete. I'm using pcs as a shell and I haven't found a command designed
to replace a node, only to add or remove them.
It seems really strange to me that there isn't a guide, since this should
be a very basic operation and it's quite important to know how to do it -
HW breaks, as a matter of fact :D
So I'll be very grateful if anyone can point me in the right direction.
Thanks in advance, and best regards

Fabrizio
