Join new node (temp disable HA?)

[sander93]

Hello,

We want to ad 2 new nodes to our cluster (9 nodes existing), but in the past we had a few times that all existing nodes going to reboot while adding a new node.
We don't know exactly what was going wrong because it was going like:

- join 6 node > all nodes reboot, after reboot working correctly
- join 7 node > not a problem
- join 8 node > not a problem
- join 9 node > alle nodes reboot, after reboot working correctly

Is there a way to prevent this? for example disable HA?
If so, can i do:
1. systemctl stop pve-ha-lrm
2. systemctl stop pve-ha-crm
3. Join new nodes
4. systemctl start pve-ha-lrm
5. systemctl start pve-ha-crm

Or do i need to delete all vm's from HA? it are around 200 VM's so that is a lot of work.

Kind regards,

Sander

I read in other topics that you also have on each node pvelocalhost in /etc/hosts
We don't have it on all nodes, can this be a problem to?
