[Pacemaker] Change Hostname

[Thorsten Rehm]

Hi everyone,

I have a cluster with three nodes (stack: heartbeat) and I need to
change the hostname of all systems (only the hostname, not the ip
address or other network configuration). I have already made several
attempts, but so far I have not managed that resources are available
without interruption, after I changed the hostname. Is there a
procedure that allows me to change the hostname, without loss of
resources? If so, how would this look like? Is there a best case?


Cheers,
Thorsten
