Am new to serverfault, hoping to see the experts answers for my query.

I have done a Active/passive setup for 1 cell vCloud Director. Below are the setup details.

  • OS : CentOS 7.10
  • vCloud Director : 9.5
  • DRBD9.0 : For data replication between 2 nodes
  • Corosync & Pacemaker : For heartbeat and resource creation.

Below is the cluster details : After creating resource VCD-SERVICE for service vmware-vcd, am getting below failed action and cluster goes into no responsive mode even if i restart pacemaker.

Resource created with this command:

pcs resource create VCD-SERVICE lsb:vmware-vcd op monitor interval=15s

Experts valuable input is highly appreciated & thanks in advance.

I believe you want to define the VCD-SERVICE with the systemd class instead of lsb.

LSB init scripts must be located in /etc/init.d, and must comply with LSB exit codes to be used with Pacemaker. In CentOS 7, most services are controlled by systemd.

EDIT 1: Here is a link to LSB spec: http://refspecs.linuxbase.org/LSB_3.0.0/LSB-PDA/LSB-PDA/iniscrptact.html

and another link to the Linux-HA.org wiki to check for compliance: http://www.linux-ha.org/wiki/LSB_Resource_Agents

It's usually pretty easy to edit an init script to make it LSB compliant, but you can also write an OCF resource agent for Pacemaker. A quick Google for, "OCF Pacemaker resource agent development" should bring up some good resources.

  • Dear Matt, thank you for your input, yes i have tried using systemd class but pacemaker is not identifying that as service, do you know how to create the resource for service using pcs. – Mohammed Suhail Jan 12 '19 at 12:22
