Hello,
I am aiming for upgrading one of the cluster node to OLE8 (current version
OLE7) and test if postfix is working fine.
If yes then upgrade the second node to OLE8.
My questions:
Will Pacemaker configuration works after the upgrade?
Do I need to make any changes before or after the upgrade to OLE8?
So server3 will be done first and then server4. Is that the right order?
Do I need to stop any services before the upgrade?
[root@server3 ~]# pacemakerd --version
Pacemaker 1.1.23-1.0.1.el7_9.1
