Hi team,
Thanks for this great job on those library.
I would like to know if it was possible to get some help on the mariadb
resource.
After the configuration of my cluster pcs command shows me:
root@node1:~# pcs status
Cluster name: clusterserver
Stack: corosync
Current DC: node1 (version 2.0.1-9e909a5bdd) - partition with quorum
Last updated: Thu Apr 8 15:45:35 2021
Last change: Thu Apr 8 15:45:25 2021 by root via cibadmin on node1
2 nodes configured
2 resources configured
Online: [ node1 node2 ]
Full list of resources:

Masters: [ node1 ]
Slaves: [ node2 ]
Daemon Status:
corosync: active/disabled
pacemaker: active/disabled
pcsd: active/enabled
But when I go to mysql on server2 I see my slave statys off:

Did I miss something on my configuration ? Or do I need more than two
servers ?
