Here is my configuration.

pacemaker == 1.1
corosync == 2.4.5

Hi,

Based on the error messages "Agent 'ocf:linbit:drbd' is not installed or does not provide valid metadata" and "status=Not installed", it looks like you are missing the DRBD resource agent and you need to install it.

Thank you so much for your assistance Tomas！
When I try to search DRBD resource agent I found this instruction yum install -y drbd-pacemaker .
Again thanks for your help.

Best Regards,
