[ClusterLabs] Error observed while starting cluster

[Roshni Chatterjee]

Hi ,

Error observed in pacemaker and pcs status
Error: cluster is not currently running on this node

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I have built the source  code of corosync (2.4.2) and pacemaker (1.1.16)  and  have followed the below steps for building a 2 node cluster .


1.       Download source  code of corosync and pacemaker (versions as mentioned above ) and compile .

2.       Install pcsd using “yum install pcs”

3.       Allow cluster services through firewall using #firewall-cmd --permanent --add-service=high-availability

4.       Start and enable pcsd #systemctl start pcsd and #systemctl enable pcsd

5.       Change password for user hacluster

6.       pcs cluster auth pcmk3 node2

7.       pcs cluster setup --name mycluster pcmk3 node2

8.       pcs cluster start -all

9.       pcs status


It is observed that the no error is received till step 8 . At step 9 when pcs status is checked error is received (highlighted below)
[root at node2 ~]# pacemakerd --features

[root at node2 ~]# pcs cluster start --all

[root at node2 ~]# pcs status

On checking pacemaker status the following issue is found -
[root at pcmk3 ~]# systemctl pacemaker status -l
Unknown operation 'pacemaker'.
[root at pcmk3 ~]# systemctl status pacemaker -l
