I encountered some problems too in my LVM resize saga.
I wanted to resize my root filesystem.
The "umount /" was reported as successful, even though it didn't 
unmounted the filesystem.
"mount / -o remount,ro" was equally successful: it didn't remount the 
filesystem, but reported success.
This is a CentOS4. I remeber with older Mandrake Linuxes I was able to 
remount the root filesystem as read-only in single mode.

Solution: hook up a keyboard and monitor to the server and boot a live cd.
A question still remains: how to un-mount the root filesystem or at 
least mount it read-only?
