I have successfully survived a hdd crash in raid1 since the system was set to boot up from second disk as well. We copied all partitions in disk one to disk two (including root) and then setup some grub magic. so that the second disk was also bootable. And this off a software raid.

Before I started using 3Ware, I had a Lilo script that did this on the second drive with a redundant /boot[.1] filesystem.

Of course, it wasn't true failover. I had to disable the other disk for it to work, or the controller board had to fail so it didn't appear.
