Hi Guys

Please help me. I am running proxmox v1.9 (I think) Linux MYSRV.starbright.co.za 2.6.32-6-pve #1 SMP Mon Sep 26 06:32:53 CEST 2011 x86_64 GNU/Linux

One of the virtual machines (there are only two) is a CentOS release 6.3 (Final) server. For some strange reason the dump seems to hang up. It is backing up to an NFS share hosted on another machine on the same physical network.

On the proxmox server I see the following output for the command ps aux |grep dump:

root 43973 0.0 0.1 49048 14308 ? Ss Nov17 0:00 /usr/bin/perl -w /usr/sbin/vzdump --quiet --snapshot --compress --storage gaddafi_backup --maxfiles 1 --mailto admin@starbright.co.za --all

So I can see the dump is running, and on the NFS server there is a .tmp folder and stuff.

So for some reason the dump of the machine seems to be hanging up. Its been like that for 5 days now and does not complete. Also when the server starts up, that specific VM doesn't start due to it being "locked" by the dump that the server still thinks is running.

Please help guys.

Thanks a mil.
 
first,1.9 is out of support, plan the upgrade to latest 2.x.
see http://pve.proxmox.com/wiki/Upgrade_from_1.9_to_2.0

to your issue:

seems the LVM snapshot space runs out of space. reboot your physical server and unlock the VM with "qm unlock VMID".

note: in V2.2, backup just stops with an error in such a case.
 
Well I red somewhere to change the NFS to CIFS and now it works fine.

There seems to be a serious issue with NFS.
