oh? what happens if you dont?
Recount from memory of 2.0.7-2.0.8 upgrade so apologies for greyness
in details...
Basically the ugraded node was taken off line, upgraded (Debian so
dpkg -i packages) then restarted. At this point the upgraded node
would attempt to start but failed to join the cluster. Regrettably no
longer have logs for this, hence I can't recall the precise reason
for this [apologies for the, therefore, somewhat anecdotal info].
Pretty much following the previously outlined process and restarting
the system the nodes would achieve a cluster status and DC etc went
fine BUT no resources were starting up on the upgraded node.
Repeating the flush and removing the contents of /var/lib/heartbeat/
pengine allowed all to come back to life and the resources restarted
as expected.
Apols again for the lack of logs, but this took place a while back
and I now perform my testing on clean vmware snapshots and hence none
of the above now applies :-)
