quorum

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...

Hi, There is now some week, I have a problem with 2 nodes cluster (Proxmox 4.4-5) When I reboot node 2, the cluster stop and say 'Quorum not ready' on node 1. I think I have a unicast problem: omping node1 node2 node1 : waiting for response msg I have see that sometime, Node1 reboot too...

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, we have cluster configuration which consists in a 2 nodes - unicast udpu (multicast not available). The cluster is up and running, I added and removed a test machine from HA. The question is, we have the following output for "ha-manager status", on this cluster, two node up and running...

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...

Hello all, I've just upgraded our 3-server cluster from last 3.x version to latest 4.x (Community Subscription) without any problems (almost). As we're running our primary firewall virtualized as well in Proxmox we changed the clusters nodes gateways (vmbr0 => eth4) to a physical firewall in...

Following the guides to remove a node from a cluster, i shutdown and deleted the node that was to be shutdown as per the instructions in the wiki (following the WARNING) that it should NOT ever go online again because that would mess upp the cluster. Now i can't write to /etc/pve at all and if...
