raid 5 my file server (read all 4 entries…)
Did this at work 4 years ago

I’ve just set up a new departmental server at work— A Linux box with SATA RAID-5.

Some lessons-learned if you’re thinking of doing this:

  1. The 3Ware 8504 is perfect for Linux. Gentoo’s LiveCD recognised it on boot-up, so I didn’t have to lift a finger to configure it!
  2. We used 4×160Gb drives. Two for storage, one for parity, and one for live failover, giving us a little room to breathe should something go awry.
  3. Get a good hot-swappable enclosure. We got one that fits in 3 5.25 external bays and it should make life a lot simpler if we do have a drive failure.

keep an eye on it...

Dont forget to monitor the health of your array, or have it tell you if it gets sick. We’ve had two disk failures on one of our RAID servers (not at the same time, otherwise we’d have been stuffed) over the past 18 months. Both have been swapped out and replaced with no downtime, just like it oughta be.

Our 3ware system has a web-based monitor and can also email when it gets ill, make sure that email gets to you!

Appreciate the tip

I’ve moved my “install 3dm” TODO up the list—It’s now after “Compile the kernel module for the onboard network adapter”, but before “install SVN”.
