I only have 2 nodes ( as mentioned above ) and since I don't have a dedicated shared storage I need drbd to provide that along with redundancy. Did I get this wrong?

I would like to know why is it recommended to have CLVM on top of drbd and then gfs2? Is there something that I miss here? I am about to start this system in production and I imagined that the simpler the config the better.. but everywhere online I see the standard setup using CLVM in the middle.

Beaware of the fact that ksm is eating up CPU so depends what resource is more important to you.. ram or cpu..

You can do that but then issue: qm rescan -vmid xx where xx is the id you assigned for this vm.

Maybe I got this HA wrong? Is this normal behaviour? on node failure the VM gets restarted on another node?

I guess he is talking about the disk device not the network one. You can edit the .conf file of the VM and change idex to virtiox for the disk you want ( after a total shutdown of the VM changes takes effect ) However you should note that this will change from /dev/sda to /dev/vda so any...

I have read this in a previous thread: http://forum.proxmox.com/threads/6400-KSM-not-working maybe you are in the same situation? Not using at least half of the physical memory yet and not having what to dedup for the moment?

The reason I defined 2 domains and 2 services is because it's the only way I found to mount the gfs2 on both nodes simultaneously. Without the 2 service definitions it only gets mounted on one node: Member Status: Quorate Member Name ID...

Hello, I am trying to make a setup of Two-Node HA ( https://pve.proxmox.com/wiki/Two-Node_High_Availability_Cluster ). I have 2 identical machines (Dell R720 with idrac7) and I have setup a PVE Cluster with these 2 and a quorum disk via an iscsi target from a third-machine. Although everything...

On the cloned server check: /etc/udev/rules.d/70-persistent-net.rules Because you have different mac-addresses for the NICs you may need to adjust that setup or maybe even delete the file and reboot. To check if you really have operational NICs just issue "ifconfig -a" to see the list, they...
