[PVE-User] Missing node in ha-manager

It looks like the PVE cluster filesystem is out of sync or has a
problematic connection to corosync.
From corosyncs stand point the node addition worked, and is consistent
on all nodes, which is good.
Now, some log from `proxmox03`- the problematic node - would be nice:
# journalctl -u corosync -u pve-cluster
As I may not get back to you until Tuesday I give you a quite possible
I'd suggest restarting pve-cluster *but* as the pve-ha-lrm and its
watchdog is active on node proxmox03,
it could result in a node reset *if* pve-cluster cannot connect back to
corosync or fails in another way.
This is not likely but if you can not schedule a maintenance window it
should be taken care of.
First restartthe pve-ha-crm so that another mode takes up the master role.
Then either move all HA-Services from this node or remove them
temporarily and stop the pve-ha-lrm and pve-ha-crm services:
# systemctl stop pve-ha-lrm pve-ha-crm
now restart the pve-cluster and corosync (just to be sure) service:
systemctl restart pve-cluster corosync
# cat /etc/pve/.members
It should show all members and the same version number as the other
members. If thats the case start pve-ha-lrm and crm again,
all should be clear now again.
Oh and sorry for getting back a bit late :)
