I have a two-node, six resource cluster configured.
Two VIP addresses w/link monitoring, and a DRBD master/slave set configured
exactly as in the Clusters from Scratch documentation.
I want to make the DRBD master always be on the same node as the ExternalVIP in
my configuration.
To do this, I run:
# pcs constraint colocation add WebDataClone with ExternalVIP
This causes the secondary DRBD node to stop.
Is this expected behavior for the pcs constraint command that I showed? If so,
what is the proper procedure for making the Master node always be running on the
same node as my ExternalVIP?
Can you try 'pcs constraint colocation add master WebDataClone with ExternalVIP'
Thanks,
Chris
