Hello,

We have installed a fresh 3.2 version on server few days ago. We have restored VMs from backup and everything work fine for couple of days.
Web GUI worked fine but after hiting Ctrl-F5 (refresh) in browser everything broke down. Blank page. Can't access from any computer and browser.

Here is page source code:

Also, we can't execute pveversion -v, vzdump... commands
Code: 
-bash: pveversion: command not found
-bash: /usr/sbin/vzdump: No such file or directory

Code: 
Linux proxmox1 2.6.32-29-pve #1 SMP Thu Apr 24 10:03:02 CEST 2014 x86_64 GNU/Linux

VMs still working and we have SSH access.
Any idea how to fix this?

We can't execute command pveversion -v

-bash: pveversion: command not found

Finally we have found what couse the problem. We have tried to uninstall SNMP, and didn't notice that this action will remove some core components (fence-agents-pve proxmox-ve-2.6.32 pve-manager snmp).
Code: 
root@proxmoxtest:~# apt-get remove snmp

Our new question is how to revert this in safe way. This is our plan:


To added to file /etc/apt/sources.list pve-no-subscription repository:
Code: 
deb http://ftp.debian.org/debian wheezy main contrib

# PVE pve-no-subscription repository provided by proxmox.com, NOT recommended for production use
deb http://download.proxmox.com/debian wheezy pve-no-subscription

# security updates
deb http://security.debian.org/ wheezy/updates main contrib
Then to instal proxmox-ve-2.6.32
Code: 
apt-get install proxmox-ve-2.6.32


Then to remove pve-no-subscription repository from /etc/apt/sources.list and apt-get update and apt-get dist-upgrade

Are we on right path?
