[PVE-User] 2node cluster

[Dean Mumby]

just create a proxmox vm within each node and join them to the cluster , then you should be able to have each node run independently.

Subject: [PVE-User] 2node cluster

Hello to all

I'm testing pve-storage-zsync and it works pretty well on my 3node 
cluster .   One VM from origin node is replicating to other two nodes 
and when I shutdown origin node , I can start VM from it's replicated 
image on one of the other nodes w/o any issues/problems. If I make some 
changes to this replicated image , after starting "dead" node back 
again, replication overrides those changes and so on ...

So this is possible because we still have quorum .  However real 
scenario will have only two nodes in cluster and the problem arises when 
one node shuts down and there is no quorum any more.

Then we have to lower "votes" on the surviving node.

Since I want to make zfs-sync (disaster recovery) test with 2node 
cluster ,  the question would be: Is it possible to start "dead" node 
back again and restore "votes" value on the surviving node ?      Will 
the cluster accept this "dead" node back ?

I have never done this before  and just want to be prepared for 
reinstalling dead node if it cannot get back into the cluster again ....

Thank you very much in advance

and

BR
