Hi, tonight is the second time I face a huge problem when trying to add a node to my existing cluster.
My cluster contains approximately 15 nodes, I use CEPH as storage and everything is working pretty good.
All our nodes and "future" nodes FQDN are contained in /etc/hosts like :
I have a problem with my Qdevice. If I type "pvemc status", my first node give the following result:
root@pve1:~# pvecm status
Config Version: 7
Secure auth: on
I am currently dealing with a problem in a hyperconverged (ceph) where the whole cluster reboots seemingly at random. Every single one (of the total of seven) node resets at the same time. I am suspecting corosync to not be able to communicate properly. This problem has only popped up...
I'm looking to update the networking setup for Proxmox VE now that the switches have been swapped out for more capable models.
At the moment, each host has 1x NIC connected, which is serving VMs (WAN) and PVE (Web GUI, SSH, Corosync, etc). Static addressing for PVE is set against...
May be someone can help, how to add second PVE cluster (as observer) in already exist PVE Cluster.
How i can add here second separate CLUSTER-2?
# cat /etc/pve/corosync.conf
i have up to 16 nodes in a proxmox cluster and corosync is constantly showing retransmit in logs:
Jan 05 13:38:15 node2 corosync: [TOTEM ] Retransmit List: 66a9
Jan 05 13:38:23 node2 corosync: [TOTEM ] Retransmit List: 6708
Jan 05 13:38:30 node2 corosync...
Before I had a cluster of 13 nodes. I added 3 other nodes and within 5 minutes I lost the whole cluster. After restarting corosync 1 by 1 but when I start a 15th node I have this message:
corosync: [TOTEM ] Token has not been received in 380 ms
then after a few minutes the cluster...
I have four servers in a cluster. The last night, we faced to a big network flapping on 'srva' (private network and public network) with an impact to the private network '10.50.255.0/24'. The expected behavior was to get the three nodes (srvb, srvc, srvd) working together and the node...
I have a problem getting a QDevice to work on proxmox 6.2-12
First I install the QDevice package on the 3rd witness (Raspberry Pi OS 20-08-2020) box:
# apt install corosync-qnetd
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following NEW...
I have (had) a 3 node Proxmox VE 6.2-11 and Ceph cluster. I'm modifying my config after install and some light use. Ceph is now on its own 10Gx2 LAN. I decided to dedicate a 1Gb interface and create a VLAN for corosync and attempted to modify corosync.conf before understanding exactly what...
I currently have a 4 node HCI cluster that's working quite well. It will be expanding to 8 nodes total and be used for critical services. All of the testing was satisfactory and management was duly impressed. I am reinstalling the cluster from scratch in order to ensure none of the testing bits...
Hello. I recently installed Proxmox in 1 one physical server (node). I was browsing around the node's settings when I noticed that under System, it is saying that the status of the Corosync Cluster Engine is dead. I did some Googling and learned that the Corosync Cluster Engine is how physical...
I'm sitting with an issue, we replaced some of our servers in our cluster... And somewhere we made a mistake..Can someone please help me. We would like the public IP range to be the 129.232.156.xx range, and the ceph data sync ip range 10.161.0.xx
The reason obviously being that...
Ich möchte nun mein Corosync-Netzwerk auf eine andere Netzwerkschnittstelle legen mit folgendem Wikiartikel. Zurzeit befinden sich nur 2 Nodes im Cluster.
Meine bedenken sind nun das wenn ich die Datei gemäß der Anleitung ändere zur neuen Netzwerkkarte, as ich dies nur auf dem einem Node über...
Hi to All,
I'm writing here since i can't find enough information about the issue I'm facing.
I have decided to test 4 nodes cluster with proxmox . Everything was running just fine for the last 4 weeks.Ceph running good.Vm's running well no issues.
Yesterday I have decided to update /upgrade...
I have two proxmox ve 6.2 servers, one in France and one in Germany.
I have setup a layer 2 vpn between the two sites (germany site beeing the server by itself [dedicated server hosting solution]).
The two servers can contact each other through the vpn lan on all ports.
I am about to manually change the corosync config on my PVE cluster to introduce a 2ng Ring-Interface. I have read up on how to do that and although I am pretty sure, I got the config right, I was wondering if I could somehow prevent my nodes to be fenced, should I have messed up the new...
A couple of daya ago, we experienced an issue with a switch, which carried the corosync traffic for two of the 6 PVE hosts in our cluster. I can understand that PVE fenced those two hosts, but why did the other 4 ones rebooted as well? How can I fin out, what caused all my nodes to reboot...
Last night we tried to add a new node to the cluster, it stuck on joining showing the below messages:
can't create shared ssh key database '/etc/pve/priv/authorized_keys'
(re)generate node files
generate new node certificate
unable to create directory '/etc/pve/priv' - Permission denied
Hi all ,joined a new node(4th) to my existing proxmox cluster(3- node cluster) and it joined after 15 min showing waiting for quorum, after that it joined but after restart it is not joining the cluster. after 30 in or so it is joining again .
