[ubuntu-uk] Ubuntu Server Upgrade -- how long should I wait for server to restart?

Hi John and Tyler,
The situation is that the server was moved to a virtual platform a few months ago.  Since then I only have remote access if the server has fully restarted.  If a problem such as this develops, then I have to rely on our IT department (where linux skills are thin on the ground) who in turn rely on the providers of the virtual platform.

1.  The providers of the virtual platform report that they have restarted the server, but this has not restored my access.
2.  I do not get a response from pinging the server -- however, I have heard that ping has been disabled by our network administrators.
3.  This is what the monitor was displaying:
"Gave up waiting for root device.  Common problems:
 -- Boot args (cat /proc/cmdline)
  -- Check rootdelay= (did the system wait long enough?)
  -- Check root= (did the system wait for the right device?)
 -- Missing modules (cat /proc/modules: ls /dev)
 Alert! /dev/mapper/eprints.mdx.ac.uk-root does not exist.  Dropping to a shell!
 BusyBox v1.13.3 (Ubuntu 1:1.13.3-1ubuntu11) built-in shell (ash)
 Enter 'help' for a list of built-in commands.
 (initramfs) _"
Many thanks for you assistance!

I have just gone through the procedure of upgrading from Ubuntu server Hardy Heron 8.04 to the latest version (10.04 LTS), using the upgrade manager.  The procedure took a couple of hours to complete, and then I was asked to restart the server.  This I did, but that was half an hour ago.  How long should I wait for the server to return to life?
Many thanks.

Hello Alex,
How long you should wait probably depends on what the server is doing now.  You request does not state what state the server is currenty in, so it is difficult to advise.

Has the server actually rebooted or is it still thinking about it?
Did you select reboot or shutdown ?
How far in the boot process did the server get after the reboot?  
Did you see the the bios screen?
Is there anything showing on the monitor, such as a little white flashing cursor?
Do you get a response if you ping the server?

If there is no disk activity and you cant ping the server and there is nothing on the screen, then it sounds like a manual reboot is in order.  If so, then try Ctrl-Alt-Del keyboard combination as a more elegant way to shut down the server (compared to the reset button).

The more information you can give us then the better chance we have of giving you something other than general information.

Thank you
