I have an interesting problem on my test server. While attempting to
add a mailbox using cyradm as user cyrus the process hung. The
partition that the mailboxes are on is an lvm volume with mount point
/var/spool/imap. When I try and check the volume I am told that
their is no entry in /proc and that lvm-mod is not loaded.
The system will not shutdown via #shutdown -r now
Uptime shows a system load of 27+ but ssh response time is
unaffected.
Top gives this:

Questions:
1. How do I force a reboot remotely via ssh?
2. Why is the system behaving so strangely?
3. Why did the lvm drop off the map?
Suggetions welcome. Please address replys to me directly in addition
to the list as I subscribe to the digest version.
Regards,
Jim
