Hi
We have a mission critical Dell rackmount server.
I tried to reboot it via an ssh session and it just kept running!
The command I used was:
[root@vle tmp]# shutdown -r now
Broadcast message from root (pts/0) (Tue Oct 10 08:28:44 2006):
The system is going down for reboot NOW!
Looking at /var/log/messages it says:
Oct 10 08:28:44 vle shutdown: shutting down for system reboot
But the server just keeps on running!!!
I have an identical hot backup box and it happily rebooted this morning.
Any suggestions most welcome...
Thanks
Clive

Did you try the reboot command?
Failing that, does the shutdown -h work?
There's always the "kill power" option, but that's not recommended for the health of your disks...

Check the running processes with either "ps -efl" or "ps auxww", look for references to shutdown/init and try to figure out what's going on.
I'd guess there's an uninterruptible process running, init's trying to stop it but can't. You need to find it and try killing it, possibly a "kill -9" though be careful you know what it is you're killing.
You could also try "init 6" or "reboot -f" to see if either of those will successfully restart your system.

Hi everyone
Thanks for the suggestions :-)
There was a problem with the Clamscan AV process that was taking 100% CPU time.
I killed the offending process, but the system would still not reboot.
On visting the server room we found the vle server terminal session frozen.
On rebooting the kvm switch in the server room the VLE server automatically rebooted!
Presumably there was a running process preventing the reboot command from taking effect and unfreezing the terminal session somehow freed things up.
The server is running fine again now :-)
Most strange...
Best wishes
Clive
