Hi,
I second the never use Hardware RAID for anything important.
Especially when nobody has bothered to back stuff up because its an
ancient system that nobody understands but managed to clone onto newer
hardware.
I had a very bad 2 weeks doing post death data recovery on a high end
controller that decided the array didn't exist any more, then decided it
was actually 2 arrays not 1 and corrupted everything.
Thankfully I was testing Riv at the time as a replacement and had it in
place as an emergency backup. Riv had a successful trial by fire and
we've been running it full time since early 2013.
Weirdly after recovering the data (I managed to use linux to manually
rebuild a raid 5 by guessing controller settings and further guessing
which disk had all the corruption) controller and all disks are still
working to this day. Every data recovery quote I had was in the region
of £10,000+ to recover files which were useless without the database and
everything else working along side it.
Regards,
Wayne

For Option 2, this would be pretty straight forward. Install Linux
(the
broadcast appliance) as a mirrored / RAID setup, install Rivendell
then
restore your /var/snd and your database. And as long as you use the
same machine name and IP address you'll be back up and running in no
time. While you might not learn as much about the inner workings
of
Linux, in some ways this may be more valuable to you as you will
learn
how to restore a Rivendell database and audio files from a backup
and
get the system back up and running.
Since he mentioned an LPFM, this is the option I would recommend.
One can learn on their own time.
When a station is down, and your audience is ( permanently )
leaving,
is not the time to learn the quickest best way back on the air.
I will mention unless you're using a system with a high-end RAID
controller card, I'd recommend going with the Linux software-based
RAID
setup as opposed to some of the RAID setups they have on some
motherboards.
HEAR ! HEAR !
The reason? Aside from the fact that a lot of the
onboard RAID's only seem to work with Windows, if something happens
to
fry your system's motherboard, if you've used the Linux software
RAID
then you can install your hard disks in another system and it'll
still
see your RAID array.
Not to mention that should you lose hardware and one disk, the
remaining disk
can most often be read on/by most any modern linux.
If you use an onboard / hardware based RAID then
you're stuck looking for something with an identical chipset.
Often worse !
I've seen ( too often ) where even identical chipsets identical
controllers
will not read ( or even recognize ) disks created by another.
Hardware RAID is strictly for performance, not data security.
Linux software RAID can be set to e-mail or otherwise notify you
when
something goes worng. Most hardware RAID, you know nothing, until
all is catastrophically lost.
