well, I am not sure if what I did is right or not, but:
# vim /etc/ha.d/ha.cf
crm on
// now crm_mon displays things as usual !!
# crm_mon -i5

Current DC: node2.mydomain.com (8e8ca99f-ff34-45c7-814b-d73d69889441) -
partition with quorum
Version: 1.0.6-f709c638237cdff7556cb6ab615f32826c0f8c06
2 Nodes configured, unknown expected votes
0 Resources configured.

Online: [ node1.mydomain.com node2.mydomain.com ]
Now, I 'll configure my resources under pacemaker as I always did and let
you know of any progress / problems.
Thank you Dejan for keeping up with me on this issue :)
