Re: Raid 5: Lossless music archive server recommendations

you can setup mdadm in the monitor mode and configure
it to send email alerts.

I'm aiming at a very similar setup as what you're
talking about. Whether or
not you put your root on the raid is up to you.
Personally, I don't, and I
have my raid mounted as /home. Anyways, your mobo
should support two drives,
and each additional controller should support two
drives. Thus, with one
addon controller, you can have 4 drives. With 200GB
drives, that's 600GB of
space doing RAID 5. In my experience, adding more
drives to an array is
extremely easy, but it is dangerous. It is possible
to lose data even if you
do follow the steps verbatim, although I've done it
3-4 times myself with no
trouble. First, you must use raidreconf to grow the
array onto the new disk,
then you must use resize2fs to expand the filesystem
to fill the array.
Backing up during this process is highly
recommended!

I personally don't use a hot spare, and I haven't
had any trouble with drive
failure since I got rid of all my IBM drives. I did
have a run in with a WD
drive that needed a firmware update else it dropped
out of the array
periodically, though. A hot spare is something to
take into consideration.
Also, you might look into some sort of monitoring
script. If you don't
monitor the array, you could lose one disk and go
months without ever
knowing. Something that would email you would be
ideal.
