Dominik,
Does option 3 cause HB to recycle the resources when you re-attach
them?
nope - that would defeat the point :-)
If not this approach would be better than what I'm doing using a
rolling upgrade with one fail-over - if the resource can stay up
throughout upgrade process.
Thanks...
Phil Pinto

Me again,
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)
* detach and reattach (all nodes at once with resources still
running)
* other?
I'm interested to know how popular the various methods are.
Andrew
I prefer no. 3 (detach and reattach).
Works quite nicely.
Regards
Dominik
