Hi all, Some customers are asking for desktop virtualization features. As far as I understand, it is possible to run client OSs under Proxmox (I have used it with Windows XP) and then let the user access them through console, which is not optimal for a client environment. Now I see SPICE...

We have finally managed to make it work following other approach. We directly modified the sqlite database managing all that stuff and things are ok now... too complex perhaps ! Thanks.1

That's it, I did not know the "bonding" name ! thanks.

This command complains about that cman is not running... because there is no quorum... any more choices?

Hi all, It seems we did a mistake and broke the cluster conf. Now, quorum is never reached and the cluster does not start. We have tried to manually create a cluster.conf.new file and apply changes, but nothing works. We are even unable to write on /etc/pve. We have tried stopping the...

Hello, Does anybody know how to configure a multipath for pinging between the nodes of a cluster?. This way, if a network connection fails, I would have an alternative path... Thanks in advance.

Hi, I am writing the wiki that explains how to create a simple two-node HA-enabled proxmox cluster without the need of external shared storage nor quorum disk partition. See it how at: http://pve.proxmox.com/wiki/Two-Node_High_Availability_Cluster and please, let me know how to improve it. Jose.

Hi, I have just applied for access to the Wiki. I will be delighted to help on documenting the Wiki and support this way the open source community. I suppose I will get a response from admins but if not, I have registered with username jrbcast@iXXXXa.com Bests.

It worked !!. We had a problem with the fencing manager. We were using fence_ilo_mp instead of fence_ilo and we did not have an "action" label on the config.log. Hope this helps !!

Does that mean that HA is not going to work under proxmox in the event of a power outage?. It has also failed when disconnecting the ethernet interface for data (the fencing one is connected). It has been detected the other node is offline, but no fencing appears on the log then.

But corosync seems to be working. In fact, if I stop RGManager on one server, machines are migrated as expected to the other machine. In any other case they won't be migrated. I desperately need to get HA working :-(.... We would be delighted to help writing the Wiki regarding this if we get it...

And... what about multicast?. Is it needed or not in a two-node environment?

But wait a moment... If I pull the cable (or power goes offline), the fencing is going to fail always... iLo has no power to answer....

Thanks, those are good news. Here is the log from the "alive" machine: Jan 18 08:32:33 almerimar corosync[1974]: [QUORUM] Members[1]: 2 Jan 18 08:32:33 almerimar corosync[1974]: [CLM ] CLM CONFIGURATION CHANGE Jan 18 08:32:33 almerimar corosync[1974]: [CLM ] New Configuration: Jan 18...

Dear Tom, As Dietmar stated on the last post from this thread: http://forum.proxmox.com/threads/7786-Cluster-and-quorum?highlight=qdisk it is possible to give two votes to one of the nodes. Does this mean no qdisk should be needed then?. We have enough redundancy on our interconnection...

Yes we do. Here you are the conf: <?xml version="1.0"?> <cluster config_version="38" name="murgiHA"> <cman expected_votes="1" keyfile="/var/lib/pve-cluster/corosync.authkey" two_node="1"/> <fencedevices> <fencedevice agent="fence_ilo_mp" ipaddr="192.168.0.102" login="userilo"...

For example, we are using hp's ilo as a fencing method. it seems to work !.

Dear proxmox developers, We have correctly configured HA following your demo video (thnaks a lot !). It does migrate an HA managed machine as soon as we stop the RGManager service. So far so good. Nevertheless, if we try the "classical" approach for testing HA it does nothing: - Pull power...

I self-reply: - Install "fence-agents-pve" - The agent is called "fence_ilo_mp" instead of just "fence_ilo". Hope this helps !. jose.

Hi, We are trying to configure HA using fence_ilo but we keep on getting a 500 error. It seems to complain on the cluster.conf where we define the fencing devices. We realized also that fence_ilo was not included in the CMAN packaged shipping with Proxmox (we made a Debian+PVE installation) so...
