Hello Everyone,

I am trying to configure an active/active cluster. Built from source are:

Pacemaker 1.1.6
Cluster3
Corosync 1.4.2

Starting corosync instead of cman, crm works (RA fire up),
however when starting cman, I am not even able to attach
to the running cluster using crm (crm_mon, _config etc..).
This is on a VM prototype:

/etc/init.d/cman status
cluster is running.

/usr/etc/init.d/corosync status
corosync (pid 3736) is running...

/usr/etc/init.d/cman start
Starting cluster:
  Checking if cluster has been disabled at boot... [  OK  ]
  Checking Network Manager... [  OK  ]
  Global setup... [  OK  ]

  Starting cman... [  OK  ]
  Waiting for quorum... [  OK  ]
  Starting fenced... [  OK  ]
  Starting dlm_controld... [  OK  ]
  Unfencing self... [  OK  ]
  Joining fence domain... [  OK  ]

crm_mon -1
Connection to cluster failed: connection failed

Is it possbile the new installation of cman is not able to get the existing
CIB configuration running? If so, can I just delete the existing CIB, if so
what do I have to delete?

Thanks in Advance,

Nick.
