[Pacemaker] Which Linux to use for cluster

[Dominik Klein]

Hi Norbert

I don't know what you did in 11.2, but I'll try to tell you what I do.

I'm mostly still on 11.1 and use the clusterlabs repo. After installing
the operating system from scratch, pretty much all I do is following the
install page from the wiki http://clusterlabs.org/wiki/Install

ie
 zypper ar http://clusterlabs.org/rpm/opensuse-11.1/clusterlabs.repo
 zypper refresh
 zypper in pacemaker corosync heartbeat

then use corosync-keygen, after that copy the /etc/corosync/authkey to
the other node and head over to the page referred to at the bottom of
the install page:

http://clusterlabs.org/wiki/Initial_Configuration

then copy/paste /etc/corosync/corosync.conf, adjust to my network
configuration and then start corosync on both nodes.

That's a matter of minutes actually.

Then, from there, I'd suggest you start with simple resources (agent
"Dummy") and play around with the cluster. Play with it and learn what
the cluster does in which situation.

It's proven not to work too great if people _start_ with clusters and
instantly try to build complex setups (as you're seeming to). From what
you've written so far, I think you'll either need some time to learn or
some money to get someone to do it for you.

The documentation is really, really good by now. People have put a
tremendous amount of work into that (especially Andrew, Dejan and
Florian as far as I can tell) and it surely paid out.

I'd suggest you read
http://www.clusterlabs.org/doc/en-US/Pacemaker/1.0/pdf/Pacemaker_Explained/Pacemaker-1.0-Pacemaker_Explained-en-US.pdf
and http://www.drbd.org/users-guide/

That should get you started.

Regards
Dominik
