  3. [SOLVED] Prevent node fencing while updating corosync config

    Hi, 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...
  4. Why did PVE reboot all nodes im my cluster, when only 2 needed to be fenced?

    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...

  8. Trennung Netzwerkinterfaces Corosync/HA

    Guten Abend zusammen, wir setzen bei uns grade ein neues PVE-Cluster mit 3 Nodes auf (mit ZFS und Storage Replication). Netzwerkkonfigurationsmäßig würden wir gerne folgendes machen: 1G-Port: Corosync (10.0.11.x) (damit das sich nicht mit anderen Paketen in die Quere kommt) 10G-Port: Storage...

    corosync 3.0.2-pve4 memory leak

    I have a (possibly unrelated) problem where one cluster member's TOTEM keep generateing retransmits from other nodes or local timeouts. When I checked nodeC kept joining and leaving the cluster, about 50 per seconds. Restarting corosync resulted the same. It turned out however that on other...
  11. Moving cluster nodes to a different network - missing ':' after key 'interface' (500)

    So, I was following the directions to separate the cluster network, and things started to seem like they were going alright with the first node. However, when I rebooted the node, Datacenter view\Cluster says, missing ':' after key 'interface' (500). I then check the /etc/pve/corosync.conf file...
  12. Quorum Activity blocked

    Hi there, We have a proxmox cluster, with each node in the same subnet. The cluster contained 3 hosts and everything worked as it should in the last years. Recently we wanted to add a new host to the cluster. This host is also in the same subnet, nothing changed in the network confugration...

  14. [SOLVED] PVE 6.0/corosync over WAN (high latency) - looses sync

    I am running PVE cluster over WAN (different datacenters across the globe). It worked all the time flawlessly and best suited my needs (of course no shared storage, LM or HA but still central management, easy offline migrations etc). Some time ago I've upgraded to PVE 6.0 and was able to run the...
  15. Corosync & variable number of nodes in a cluster

    Hello, I currently have a cluster of 2 promox with "two_node : 1" in corosync quorum setting. This cluster will grow to 6 servers. However, for reasons of maintenance it is possible that only 1 node is active on the 6. Because of the qorum vote, it is impossible to make a 2 node cluster work...
  16. [SOLVED] cluster network and storage network

    hi everyone! We are migrating our server to a different cloud provider. While reading a documentation, i read this: "Storage communication should never be on the same network as corosync!". Our server must have HA and data redundancy/ data high availability (using ceph). The problem is, our...

  19. PVE6.0-5: Corosync3 segvaults randomly on nodes

    Hey guys, we updated from PVE5 to PVE6 recently and noticed that nodes on our 4-node cluster leave randomly. Checking pvecm status states that CMAP cannot be initialized, so I had a look at corosync on the failed node only to learn that it obviously segfaulted. This happened on 3 of 4 cluster...

    Corosync 3

    Hi, Corosync 3 doesn't use multicast anymore. It uses unicast. Ok, so I guess the cluster traffic should grow a lot for clusters involving more than 3 nodes ? Thanks in advanced, Antoine
