rw — Fri, 26 Mar 2010 16:34:10 -0400

set up RAID0

Create a full-disk partition on each of two drives to be RAID0 combined. Set each full-disk partition as type fd - Linux RAID Auto-detect. Use fdisk or your favourite partitioning tool.

Then:
mdadm --create /dev/md0 --level=0 --raid-devices=2 /dev/sda1 /dev/sdb1 sudo /usr/share/mdadm/mkconf force-generate /etc/mdadm/mdadm.conf sudo mkfs.ext3 /dev/md0 mkdir /raid sudo mount /dev/md0 /raid

Everything okay to this point? Add the raid to fstab to mount raid automatically after reboot. read more »
