I am trying to add replication support for my software.
I installed drbd, pacemaker and corosoft. OS used: Ubuntu 12.04.4 server
edition.
DRBD: 8.4.4 installed from source.
Pacemaker, corosoft installed using apt-get
I tried to add the drbd resource agent to the crm configure command:
crm configure primitive drbd_pg ocf:linbit:drbd params drbd_resource="pg"
op monitor interval="29s" role="Master" op monitor interval="31s"
role="Slave"
crm configure ms ms_drbd_pg drbd_pg meta master-max="1" master-node-max="1"
clone-max="2" clone-node-max="1" notify="true"
The crm_mon shows the following status:
