corosync cluster

Hello all, I am running into a seemingly unique issue where my cluster will splitbrain on its own. This happened on last reboot and seemed to start because the /etc/hosts file no longer defined the correct member ips and host names. I fixed that and the cluster will work for about 3 minutes...

I am putting together a 3x node cluster for my own education (before doing this for real at work!) and I have the following plan for subnets for the cluster. This setup is based on all the tutorials I've been able to find online, but I wanted to make sure I'm doing this right. I have enough...

Pve1 was running pvecm e 1. pve2 and pve3 were shutdown and brought up together. How do check logs PVE1 reloaded due to losing quorum ? I brought up pve2 and pve3 15:57:15 -- pve2 started 15:57:24 -- pve3 started 16:09:07 -- Pve1 lost watchdog and reloaded(Losing 3 HA VM) PVE1 Aug 31...

Hello, I just upgraded from 7.4 to 8, everything went ok until now. I have 2 nodes at home, which I use in a cluster. The node I am having trouble with is the one I upgraded (both are, but the other one I had to do a fresh install). I followed every step on the wiki and it all went fine, just a...

Hello together! Maybe you can give me some tips? I am planning a PVE cluster with 4 HPE servers following network cards per node: 4x onboard NICs (total 4x 1Gb) 4x Intel X520-DA2 PCIe (total 8x 10Gb) Network: 2x switch with 28x 10Gb and 4x 25Gb (LACP 802.3ad is supported but unfortunately no...

Hello we had a very serious problem with the Proxmox cluster on OVH, our vRack stopped working. We tried to solve the situation by hot adding a new corosync configuration with a redundancy link in it. The configuration worked and corosync saw all members, we then restarted the proxmox cluster...

Dear Members, I have a ceph cluster with the followed details: Cluster works on separated NIC, active-backup bonding, separated DELL 10G switch, and separated IP range on 10Gbit. My problem: On all of nodes there are some KNET link down entries when there is heavy load on some of node. I don't...

Hello, i just replaced the NIC's on all my 3 nodes and i upgraded to 10 Gbit's SFP+. All nodes can access each other over ssh without any problems. But since i replaced the NIC's im not able to access the nodes at the web GUI or at least node1 cannot access node 3 or node 2 anymore. I only see...

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...

I have created a five node cluster and configurations are as follows bond0 created using two physical interfaces on each node bond1 created using two physical interfaces on each node Created Linux bridge as follows Create vmbr0 using bond0 and vmbr1 using bond1. Each node primary ip ( cluster...

Hello, I have got 3x proxmox nodes in a cluster. This cluster worked fine up until some 4 hours ago, when the bond between them broke. I have pinned the issue down to the 3rd node that is causing havoc on the corosync level. If I stop corosync, the two other nodes join together just...

Hey Everyone, We recently had a network failure in one of our data centers. The network failure caused all of the proxmox nodes in our customer to fence themselves. They're back up an running, and the cluster shows all nodes in, but we're having the following issues: 1. HA no longer works...

Hallo Zusammen, ausgangspunkt ist ein Cluster bestehend aus drei Knoten fertig konfiguriert ceph und erkennung der nodes alles einwandfrei. Jetzt haben wir diesen Cluster testweise in ein Serverzentrum verfrachtet und die IP Adressen aller Knoten mussten geändert werden. Habe die IPs einfach...

We had a critical server power failure taking down the entire cluster (inverter on ups failed, knocking out mains breakers and killing all servers before maintenance staff could reach power room) 6 server cluster (vwk-prox01 to vwk-prox06) Shared storage folder mounts properly on all servers...

I have created a new cluster with 4 nodes, the problem is that when I reboot them all of them are working, but after some minutes some of them says that are disconnected. When this happens I execute in the shell node: service corosync restart After execute this command the node is online...

I am trying to create a 3 node cluster initially with the latest Proxmox 5.0-30. I created the first node and then added the 2nd and 3rd nodes and had full quorum for like 3 minutes, then 2 machines exited. See below, this is a newly installed cluster so this isn't making much sense. 1st node...

I have a cluster running, and I am trying to add a new node but receive the following error root@vhost05:/etc/pve# pvecm add vhost13 detected the following error(s): * authentication key '/etc/corosync/authkey' already exists * cluster config '/etc/pve/corosync.conf' already exists * this host...

Hi guys, have a problem: Master server: Slave server config: I'm trying to execute on slave # pvecm add 172.16.0.3 -ring0_addr 172.16.0.2 -f I have subscription for slave server too but at this stage it shouldn't care, right? I have tested completely the same configuration on 2 pm...

Hello, Two days ago, the proxmox cluster we are testing, rebooted completely :( Cluster components: 2 physical servers and 1 VM server as quorum member - 2x ProLiant DL585 G6 with ilo - 1x VMWare VM on another physical server as Quorum VM All 5 OS (3 proxmox and 2 ilo) are NTP syncronized...

Hi, I'm having a strange issue on my proxmox4.3 cluster: from time to time all nodes appears red in web GUI. Gui also sometimes is not reachable at all and I have to restart nodes.. I figured out that the logs always shows these lines, even if all is marked green: Reading the forum have lead...
