Now I'm having an issue with adding extra drives into the RAID6 array. I
was using Disk Utility but it doesn't seem to want to do it with the
array up and running, and when I take the array down I'm denied access
to the array controls so I can't tell it to add drives. Frustrating and
makes me feel as thick as a brick. I guess I will have to do it the
old-fashioned command line way directly accessing mdadm, at a reduced
system run-level of 1.

Thanks. I'll make a one-off pitch here for anyone reading this. Go to my
bandmate Mike Dickson's site and d/l band and solo MP3s for free:
