[plug] Good RAID Howto

[Kai Jones]

Running RAID1 as far as I can tell, but are there any commands I can use 
or any way to actually check that other than knowing we've got 3 x 36 
gig SCSI disks which are synced and all showing as being one disk with 
three logical mount points ?

Thanks for the info on GAM, I'll check it out.
Cheers
