Can anyone provide a tutorial or advice on how to configure a software RAID 5 from the command-line (since I did not install Gnome)?
I have 8 x 1.5tb Drives.
mdadm --create /dev/md0 --level=5 --raid-devices=7 /dev/sd[abcdefg]1
The above will create a level 5 RAID named /dev/md0 of /dev/sda1 /dev/sdb1 /dev/sda1 /dev/sdc1 /dev/sdd1 /dev/sde1 /dev/sdf1, with hot-spare /dev/sdg1
Note: RAID5 is not really recomended for such large disks. You run the risk of a complete data loss if one disk fails and the another disk fails during the rebuild.

Robert,
Why is the size a factor here? Why would this be OK with smaller disks? How would you partition this instead?
Thanks.
Boris.
