So, I am reorganizing my servers and such...

2 servers have raid built in and run raid1.
1 has no raid, and originally I ran raid1 software.

that non-raid server is going to be the web server, but I was thinking of something.

If raid1 fails, of course you are supposed to be able to have 1 disk fail, and the other keeps on truckin while you swap the bad drive.
I dont want to test that, but i will assume thats the case with this raid.

In software however, I am not sure if it ACTUALLY works that way.
I also could not get the ubuntu installer to actually set up the raid, because of some stupid flags that already existed on the drives and it wouldnt let me nuke em. (waste of 2 hours...)

SO.....
My thought is this. I have 2 drives. I wonder if running 1 drive, and then rsync to the other drive on a regular basis. That would provide me a "warm" backup. My thought is that if the main drive fails, i can quickly run down and get up and running on the alt drive.
OR. can I set both as bootable, and the machine will boot from the "first" drive, but when the drive dies, then upon reboot, it will boot from the second?

Not sure how that boot flagging works, and what happens if there are two drives flagged as bootable. But overall, is that a viable option you think? Either auto recover by way of 2 boot drives, or warm recover by way of pulling the bad drive and setting the alt drive's boot flag.
