Last night, I created my first RAID array from the commandline. It was quite
simple, I discovered.
- Create your partitions using fstab. Remember, primary partitions must be
created before extended partitions.
- Look in /proc/partions and note the new partition IDs.
- Edit /etc/raidtab and create a new RAID array. If unsure of
the syntax, look up the Linux Software
RAID HOWTO for more details.
- Type mkraid /dev/md?, where ? is the id of the
RAID device you just entered in /etc/raidtab.
- Format the new RAID device with your favorite filesystem, assign it a
mount point, and start using it!
I was impressed with how easy it was; the choices that the Anaconda
installer present for creating a RAID array made it seem like the underlying
process must be difficult, when in fact it may have been almost the same
complexity if not easier.
