Edward, If you were thinking that RAID-0 would give you anything other than a larger single file system (like ANY redundancy), you were wrong. There are still reasons for using RAID-0, but you apparently did not have a reason. Sorry you had to learn about the reasons for various RAID levels.

The device has a 1T of disk space. I decided to create a directory /DataVolume/var, use rsync to fill it up with what was in /var, mv /var to /var.orig, then symbolically link /var to /DataVolume/var. The system rebooted so I didn't break anything. I moved /var.orig to /DataVolume. MyBookLive:~# d

I've got a WD MyBook at work. I am surprised that /DataVolume is not RAID, but based on my experience, MyBook uses Busybox. I added some software from optware. In any case, you will need to manually drill down the root files system /dev/md1 and try to find out where the larger files are and manuall
