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...
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...
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...
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)

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.
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...
have a problem:
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...
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...
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...
I corrected this issue but wanted to share my experience with setting up a cluster following the Proxmox Wiki after I had already changed the IP address of vmbr0 on both Proxmox hosts. I installed Proxmox on two platforms with hostnames: proxmox1 and proxmox2. Both of the...
I found some issue with corosync after node restart. When you reboot machine corosync is failing to start on one of nodes. Not sure why this is happening. Can somebody help me out with narrowing down where problem is?

I had cluster with two nodes and it was damaged. Now I can't make backup and others.
I know, I also can stop pve-cluster and run it in local mode (pmxcfs -l), make backup and re-install all, but maybe someone could help me...
