Hi. I'm trying to create a new container in my Proxmox 3.1-3 environment, but I'm continuously having the following error: Error: can't lock container 1002 The id of the new container is 1002, of course, but I tried with other numbers too (110 for example), and I got the same error. The...

Hi. I have some Proxmox VMs which are not connected in a LAN, and I wish them to communicate together through a VPN made with OpenVPN. I with to use the VPN to insert hosts in a cluster and let VMs to communicate each others not using the public network. So I'm thinking about the future OpenVPN...

Thank you very much for your answer. Could you explain me how that device could help me for fencing features, please?

Hi. I configured a two-nodes cluster using DRDB taking the cue from http://www.nedproductions.biz/wiki/configuring-a-proxmox-ve-2.x-cluster-running-over-an-openvpn-intranet/configuring-a-proxmox-ve-2.x-cluster-running-over-an-openvpn-intranet-part-3. That articles does not tell anything about...

I understand what you're telling. I'm interested in activate drbd, which can have a file system on it (a drbd resource can be formatted as a LVM physical volume or a "true" file system), so this shouldn't be a problem for the raw files... I was asking if a configuration like this could be bad...

Thank you very much for your answer! Now the question is: the drbd howto for Proxmox tells about LVM based storage for virtual machines, but could I use drbd with .raw images too? This should permits me to avoid the conversion of all virtual machines! Thank you very much!

Hi. I wish to begin using LVM for the storage of my virtual machine to install and configure drbd, but now I have virtual machines all with the storage as raw images in /var/lib/vz. Is there a way to convert the virtual machines from image to LVM? Thank you very much! Bye.

Thank you very much! I have some questions: I have a three node cluster, but I cannot sync all VMs to all three nodes, only two, so I wish to have all VMs synced to a node of one of another two... Should the datastore have the same name on both nodes, right? How I can configure HA on Proxmox...

Hi. Is it possible with Proxmox 2.1 to have High Availability for some virtual machines without using a SAN for the storage, but local storage of both nodes? Thank you very much! Bye.

Hi. I need to change the hostname of a running Proxmox 2.1 environment with some virtual machine installed. I simply tried changing the hostname with the typical Linux way but I lost all virtual machine references in the web interface. I tried repairing the problem but after some minutes I...

Yes: root@vetest1:~# date Tue Jun 12 14:29:34 CEST 2012 root@vetest2:~# date Tue Jun 12 14:29:34 CEST 2012

Now I have a different behaviour: root@vetest1:~# pvecm nodes Node Sts Inc Joined Name 1 M 37896 2012-06-12 01:29:13 vetest1 2 M 37908 2012-06-12 01:29:16 vetest2 root@vetest2:~# pvecm nodes Node Sts Inc Joined Name 1 M 37908...

I cannot do that, because the server are hosted in a webfarm from Hetzner, so they are connected with the Internet.

Yes. Now another strange behavior. I see the second node at the master node: root@vetest1:~# pvecm nodes Node Sts Inc Joined Name 1 M 2160 2012-06-11 17:07:09 vetest1 2 X 0 vetest2 And I see it in the vetest1 web interface, but...

I reinstalled and retried, this time using the IP address instead of the DNS name: root@vetest2:~# pvecm add 123.123.123.2 Generating public/private rsa key pair. Your identification has been saved in /root/.ssh/id_rsa. Your public key has been saved in /root/.ssh/id_rsa.pub. The key...

This not... But now how I can retry?

Hi. I'm doing some tests with a PVE 2.1 cluster to learn it. I create a new cluster configuration on the master server: root@vetest1:/var/lib/vz/template/iso# pvecm create testcluster Generating public/private rsa key pair. Your identification has been saved in /root/.ssh/id_rsa. Your public...

Thank you very much. Does this happen even if I use unicast instead of multicast?

Hi. What are the operations to do when the master node in a cluster failed and it is not accessible? How is it possible to configured all other nodes without the master server? Thank you very much! Bye.

Hi. I am planning a new installation of Proxmox VE 2 as replacement for the physical environment on the same server, this for the HA features of Proxmox 2. Even if I am an hard supporter of the virtualization environments, I would like to make some benchmarking to know how much the virtual...
