Hi,
i am kind of new to pacemaker. I am trying to configure a active/passive
pacemaker/drbd/mysql cluster. Preferably all resources should run on node1 if
available, if not they should migrate to node2. I already read all the howtos,
guides and now i reached the point were i hope to get some help from you
experts. My problem is, that if i try to test the cluster with a manual
migration like
crm resource migrate grp_MySQL pinguin01-node2 nothing happens. If i manually
reboot the active node it does a nice and clean failover. It is frustrating ;-)
Thats the syslog output right after issued the command:
...
Jan 26 18:30:21 prolog01-node1 crm_resource: [12802]: info: Invoked:
crm_resource -M -r grp_MySQL -H prolog01-node2
Jan 26 18:30:21 prolog01-node1 cib: [2585]: info: cib_process_request:
Operation complete: op cib_delete for section constraints
(origin=local/crm_resource/3, version=0.795.3): ok (rc=0)
Jan 26 18:30:21 prolog01-node1 cib: [2585]: info: cib_process_request:
Operation complete: op cib_modify for section constraints
(origin=local/crm_resource/4, version=0.795.3): ok (rc=0)
...
Here you can see some debugging output (i will contribute the small script i am
using for these dumps later if i finished the whole installation, i will write
a comprehensive step-by-step howto as soon is gt everything up and working,
cause it seems to me that most oft he howtos do not face every issue):
