[Discuss] MyBookLive disk space issues

[gaf at blu.org (Jerry Feldman)]

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 manually delete them. After you locate the culprits, you
might want to check out optware for some of the commands that BusyBox is
missing (or brain dead). You might find that MyBook Live is not rotating
the logs.
