Thanks Justin. If that's the only risk, I'll go with full devices. This
will ultimately be a headless system with a separate boot drive and
only administered by me and used internally, so I'll be careful. :-)
Many thanks!

Hi all,
I have a simple question:
Is there any problem using the full hard drive (/dev/sdb, /dev/sdc,
etc) as
opposed to partitions (/dev/sdb1, /dev/sdc1, etc) when creating
software
RAIDs? I'd rather commit the full device to the RAID since I am
certain I
won't use it for anything else, and I am scripting this so I don't
want to
have to fdisk every drive before creating a RAID...that would take
far too
much time. Most mdadm documentation always refers to partitions
rather than
full devices, so I wanted to make sure it was indeed OK to use full
devices.
Please let me know. Thank you all!
Thanks!
Thomas

Best to use partitions, so if you over-write the MBR of the drive it
won't mess up the RAID (e.g., run LILO on a raid volume => oops! but if
its a partition, no problems)..
