I just read Proxmox's wiki article about deleting node from cluster, have you read this note? I ever delete a node using delnode command. After deletion, I kill pve-cluster, rgmanager (if you use HA), and cman on deleted node. About forcing quorum to be one, is command "pvecm expected 1"...

Ok, I'll make my own script to do my scenario.

Yes, right, my cluster communication use first NIC. But is it really no way to trigger fencing when the second and the third NIC disconnected? Or should I make a script to check if the network is up or down?

Hai, sherminator Have you check your data when you do a manual migration (when the node 1 die, and you turn on VMs in node 2) ? I do success (I think) on doing your scenario, but I haven't check if no data is missing. Have you check it?

Have you try to change the quorum to 1?

Hi, all.. I have 3 NIC up and configured. First NIC for Proxmox bridging, second NIC for DRBD, and third NIC for another bridging (dedicated to one VM). When I plug off the first NIC, fencing is triggered and the server is rebooted ( I choose reboot as fencing action ). But when I plug off the...

Helo TiME, I just install Proxmox 3.4 and use option menu to manage my partition. I did perfectly when install Proxmox 3.3 using boot prompt execution. But using this way, my partition not configured, and it use all my disk as lvm. Then my boot use fat32. What's wrong with my installation?

Sorry for always asking everything in this forum. I just fix my problem. I forget to start pve-cluster again after deleting cluster.

Hi all, I have two development server that running cluster before. And I try to delete cluster by stopping pve-cluster, cman services on each server. Then I remove /etc/cluster/cluster.conf and /var/lib/pve-cluster/*. I think everything looks good. And then I try to change IP address on each...

Yeah I know Manu, but unfortunately there are only two server available in my office. Besides, is there any way to do what I want?

Hello again everyone, I successfully install two nodes HA using Proxmox 3.x and use DRBD to create shared storage. All was done well. I use 3 NIC on every node, the first for iLO, the second for Proxmox network cluster, the third for DRBD's syncer. HA works amazing when a node is shutdown or...

I think you use proxmox 4.x. Do HA work properly using two node?

Hi LnxBil, Hope you can share your experience on running two nodes. I have watch a video about this two nodes HA and he show a condition when the two nodes down. Let's call the first node as node A, and the second as node B. The last time before two nodes down, all VM located in node B. But only...

Finally i create a drbd in two nodes, and downgrade my Proxmox to v3. I use direct connection from node 1 to node 2 for drbd's syncer. How about that? Do it still need a 10Gbit connection?

Do proxmox need high bandwidth when using shared storage over a network?

Hope I have one more machine to be an NSF. So, when I create a DRBD, I will have two proxmox with redundant storage and VM, right? There will be 2 identic VM on different machine and manually I choose which one will be running, is it right? Or there is another way managing this two redundant...

Hi everyone, I'm new in High Availability world and I choose proxmox as my first try. I only have 2 nodes and no shared storage. I just install this 2 nodes with Proxmox 4.x and successfully create a cluster for those. My next plan is making a High Availability. I read every documentation and...
