[Cluster-devel] when do I need to start cpglockd



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?
