Hi everyone, I'm trying to add a node to a cluster, but it keeps getting stuck at "waiting for quorum..." I can get past it by doing "pvecm expected 1" on the node, but it doesn't actually add it to the cluster. journalctl -f shows this over and over again: Jun 29 01:33:40 waifu-pve...

Hello, One of our swichs is currently the IGMP snooping querier. We plan to remove this switch which is an old Cisco 2960. Few days ago I decided to turn this switch off. All my V5 clusters lost quorum and many nodes rebooted. Is it possible to configure a second switch to be the IGMP...

I am having a hard time adding SOME nodes to an existing cluster. all nodes are freshly updated and running same version of proxmox-ve, as follows: # pveversion -v proxmox-ve: 5.1-42 (running kernel: 4.15.15-1-pve) pve-manager: 5.1-51 (running version: 5.1-51/96be5354) pve-kernel-4.13: 5.1-44...

Hi! I have 4 nodes cluster. I want to have a quorum when two of them are offline. I tried setting auto_tie_breaker in corosync.conf and corosync-quorumtool -e 2 but both methods didin't work. How to configure that? And another question, why changing corosync.conf after creating cluster with...

Ihave tried to add a node2 to newly created cluster on node1 which failed: [root@node2]# pvecm add node1 The authenticity of host 'node1 (10.0.0.1)' can't be established. ECDSA key fingerprint is SHA256:aRIk8xO64eUL5RVX7uxy5BlIeg6EjtqKc7KWnKLruQE. Are you sure you want to continue connecting...

Hi there, I'm currently trying to setup a 3-host cluster in a datacenter where multicasting isn't possible (Hetzner) so after I read about UDPU in https://pve.proxmox.com/wiki/Multicast_notes and some tests locally I was fairly positive that this is going to work. However I only was possible to...

So, I have a node that dropped off the network last week. Turns out the switch port went bad. I got it plugged into a different 10 gig port, and brought it back up. But, corasync kept restarting, and the node kept joining and leaving the quorum. I am guessing that perhaps the NIC is also...

I am having an issue with proxmox on using Ceph. Ceph itself is working great. But when I add a new proxmox unit with ceph, specifically adding a monitor it will show up as a monitor, but will show under the quorum tab quorum no. See attached screenshot. As you can see mon.3 and mon.4 have no...

Hello everybody, I'm writing this short article because I spend myself a lot of time by finding the right configuration to get this working. First of all: A 2 Node Cluster is not a very good way to create High-Availability or even Fail-over scenarios because corosync is not able to create a...

Hello, I have just setup a cluster, and the node was added successfully. However, the new node isn't communicating with the master node. and vice versa, even though it was able to establish a connection to eachother. I had to open another SSH shell to the new node and set the expected quorum to...

Hi is it a problem having an even node number (4,6,8,....) for quorum? we have a 4 node cluster where nodes are rebooting erratic (when very high load I guess...) if yes, is incrementing quorum_votes: 1 to quorum_votes: 2 on one node the solution? regards Peter

After updating a two node cluster to 4.3, I have rebooted the nodes one by one (not at the same time). After reboot none of the VM's were running, trying to start them on any node gave a cluster error: root@proxmox2:~# qm start 111 cluster not ready - no quorum? Checking the cluster showed...

Hi Guys, Need help setting up VM to start at boot but after quorum is reached. I often find VM does not start at boot due to quorum is not reached yet. I run 3 PVE 4.3 nodes in cluster with HA enabled for some VMs on top of GlusterFS, and non-HA VMs on top of ZFS RAID10, and 4x 10GbE LACP...

Hi all, Firstly, a little background so you know where I am: I used to run two physical CentOS servers at home as active/standby for a few personal projects. The active server ran mail, ownCloud, databases etc etc, and each night the active server sent a WoL to the standby and rsync'd...
