It turns out that a linux raid1 mirror looks just like the non-raid

I'd prefer not to have to deal with the "break a mirror/fail the drive/swap it out/remirror" routine. My idea is to simply bring the server down, swap out the one disk, reboot and walk away.
One is that a drive failure will mean missed backups.
That's true, but need to set up an auto-notification of the server going down to handle all the other possible failure causes anyway, and the B drive is right there on the shelf ready to go. In fact having it NOT inside the server eliminates the chance that it would be damaged by one of those other causes - I've had a failed PSU fry almost all the components in a machine. . .
