Just how big is /opt? "df -h" will tell you. You can find out what is using /opt with "lsof | grep /opt". Usually, just going down to runlevel 1 "telinit 1" will let you unmount all your non-root file systems. -snip- > OK.

Even though putting the system into single user mode (runlevel 1) stops all your system services, it's good practice to try to figure out how to do things without rebooting. Once the copy is done, and /etc/fstab has been updated, "mount -a" will tell you if things are all working.
