I agree.  I had to go through hell with a Debian mdadm system to install
the boot loader on both drives.  I know this is a problem with a few
software raid solutions.


Anyone know if this has been fixed in any OS + Filesystem/Software Raid?
One of the things that killed me was if the bootloader was corrupted on one
disk, or the disk was partially corrupted or something, in a software raid
scenario, the bios has to know to move to the next disk, but when does that
ever happen?

This was a big failing with software raid.  I am sure it could be hacked
around by placing the bootloader somewhere else...or something.
