Thanks for the explanation. I would strongly prefer not having to reboot the nodes as I have live services running on those. I have tried pvecm expected 1 to reduce the quorom but /etc/pve is still read-only after that command. I suspect a network problem between my nodes. Unicast seems to...

I am not familiar with this quorum concept, can you point me to some good resources? How can I know if the quorum is reached or not?

Apparetly not on node3. Do you have to make it run before joining the cluster? Anyway it doesn't explain why my /etc/pve is read only on node1. Any idea about that ?

Here is my setup: I have 2 nodes (let's call them node1 and node2) on ip addresses 10.19.82.1 and 10.19.82.2. It used to work nicely. I now want to add a third node (with ip address 10.19.82.3) but it fails : root@node3:~# pvecm add 10.19.82.1 unable to copy ssh ID root@node3:~#...

Yes the 2 servers are located on 2 different data centers / network. I had finally rebooted my server to get things back to normal :( Thanks everybody for your help

Yes i have 2 nodes. Even after changing the expected quorum I can't remove the node. I also tried to restart services : # service cman restart Stopping cluster: Stopping dlm_controld... [FAILED] I think I'm good for a server reboot... Thanks for your help.

Unfortunately I can't remove the node because the cluster is kind of broken : # pvecm delnode server2 cluster not ready - no quorum? Maybe I can try to re-assign the server its old IP, delete the node, change IP again and re-add the node.

Yes I am using OpenVPN with bridging/tap. Actually the 10.0.0.11 address is the address the server got when it first booted. Later I updated OpenVPN to give it a fixed IP (not from the dynamic pool) which is 10.0.0.2. But now my cluster is broken, probably because of that. So is there any way...

No one knows ? I have to reboot my server ?

I had set up a VPN between 2 servers to make a cluster. pvecm status says: Version: 6.2.0 Config Version: 8 Cluster Name: ponytech Cluster Id: 28530 Cluster Member: Yes Cluster Generation: 4784 Membership state: Cluster-Member Nodes: 2 Expected votes: 2 Total votes: 2 Node votes: 1 Quorum: 2...

Hello, I recently installed a conatainer baser on the ubuntu-12.04-standard_12.04-1_i386 template. I was surprised to find pre-installed packages such as apache2 (and configured to start at boot), bind9 and samba. What if I want to use nginx / lighttpdd / ... ? What if the server is not...
