I'm running Redhat Linux AS V4 on a DELL 6850. The server has 2 RAID arrays - a RAID1 with 70GB and a RAID5 with 145GB. I've installed the OS onto the RAID1 array (/dev/sda) - sda1 is boot and sda2 is LVM - and the RAID5 is /dev/sdb (nothing devices defined yet).
What I'm trying to do is move /opt from /dev/sda2 to the /dev/sdb disk. What's the easiest way to do this?
