I just tried to upgrade my packages form STABEL31 to STABLE32, and noticed that there is a new daemon ‘cpglockd’
That daemon is always started with the default init script. Is that really necessary?
I just wonder why rgmanager needs 2 different locking mechanism – dlm and cpglockd?
The manual page says:
-C Explicitly disable or enable CPG-based locking. The default is
to enable this when RRP is turned on (which requires a cluster
outage). This option MUST be the same on all hosts in the clus\u2010
ter and must only be enabled or disabled with all instances of
rgmanager turned off.
But why do I want to enable CPG-based locking, or why not?
