Ocfs2 users - Aug 2006 - re: question on adding a node to RAC cluster and o2cb

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Folks,
	I'm trying to find information about how to dynamically add
	a 2nd node to a 1 node RAC cluster.  I'm posting this only after not
getting the
	details from my oracle tar via metalink.

	My installation is Suse Enterprise 9 x86_64 (kernel 267).

	Installing the single node was not a problem, what is not clear is how to
prepare
	the cluster.conf file and the ocr stuff to add a 2nd or additional node.
Obviously the
	2nd node has to have all the ip configurations in place and ssh has to be
working, but
	at some point, the /etc/ocfs2/cluster.conf file has to be modified and
propagated and the
	ocfs2 mount point has to be mounted on the additional nodes ..this is where we
had problems.

	Here is what we did.
		1. setup the 2nd node with all the proper network configuration, and ssh
equivalence.
		2. we "added" a 2nd node to cluster.conf via ocfs2console and
propagated that to the new node.
		3. We tried to mount the ocfs2 mount point, but could not .. it said something
like
		"transpoint end point not found ...".

		4. We then restarted the cluster on node1 and were able to mount the ocfs2
mount point and go
		   on to add the 2nd node.

	We are trying to identify the sequence of actions/procedures to add a 2nd node
at the o2cb/ocfs2 level.

	Oracle support didn't have this level of detail, so I'm hoping someone
knows how to do this without
	shutting down the cluster on node1

	thanks

When you added the new node using ocfs2console, did it show up in:
# ls /config/cluster/<clustername>/node/

I am assuming that it was added in /etc/ocfs2/cluster.conf.

Yes, the docs does not cover this as of now. I will update the 
FAQ/user's guide
with the info.
