I've been trying to use software RAID with one partition on
internal IDE, the other on external firewire and it is not
reliable.  I suppose the fact that RHEL4 dropped firewire
support completely might be a hint.  It worked OK with
FC1 and the 2.4 kernel. The drive would not be detected
automatically, but with the right set of commands to
find it and add to the raid it would run fine.  FC2
did not work with firewire.  FC3 autodetects the drive
but crashes within a day or less if the RAID is active.
I've been unmounting the raid and adding the firewire drive
just long enough to re-sync, then removing it and it usually
works, but starting over, SATA might be a better choice.
