I'd like to get a sense of how people upgrade their clusters...
* rolling upgrade (node-by-node)
* big-bang (all nodes at once with all resources stopped)

* other?
I'm interested to know how popular the various methods are.

I prefer no. 3 (detach and reattach).
Works quite nicely.
Do you do that node-by-node or cluster-wide?
Cluster wide.
Backup cib.xml
Stop all monitor operations
Set all resources unmanaged
Stop heartbeat on all nodes
Upgrade heartbeat / install pacemaker on all nodes
Start heartbeat on all nodes
See what the cluster would do when re-activating it
<beekhof> before you turn back on is-managed...
<beekhof> cibadmin -Ql > tmp.xml
<beekhof> vi tmp.xml (change is-managed)
<beekhof> ptest -VVVVV -X tmp.xml -D tmp.dot
<beekhof> look in tmp.dot and see what we'd do
If that's to my linking:
Set all resources managed
Start all monitor operations
Otherwise: not happened yet, but at this point, I guess I could revert
to the older version with no harm.

Dominik
