Hi, all!
I set up the latest clustering sftware versions from CentOS 6.5 repo
(pacemaker 1.1.10 + pcs + drbd 8.4.4) on a two-node cluster.
pcs constraint show
Location Constraints:
Ordering Constraints:
promote ms_u01 then start u01_fs
Colocation Constraints:
u01_fs with ms_u01 (with-rsc-role:Master)
Now, when I reboot or shut down 'active' server - filesystem gets promoted
on the secondry, and filesystem gets mounted - all as expected. However,
when I move resource group with pcs resource move - resources are stopped
(correct) and FS unmounted, but DRBD resource stays Primary, after some
timeout I get failed action "monitor with role:Master" on the "target"
server and eventually resource is kept out of the target server.
I tried to add additional ordering constraint, like this:
pcs constraint show
Location Constraints:
Resource: OraGroup
Enabled on: server2 (role: Started)
Ordering Constraints:
promote ms_u01 then start u01_fs
stop u01_fs then demote ms_u01
Colocation Constraints:
u01_fs with ms_u01 (with-rsc-role:Master)
This did not change anything...
Am I missing somethig?
The previous OS (it was OpenSuSE) and software (pacemaker 1.1.8 + crmsh)
worked as expected:
