hi sonia..
I built a new rh-6.0 box too with latest raid stuff..
I had an old rh-5.x box with mdadd/mdcreate ...
To make it so that the original /home ( /dev/md0 ) worked with
the new rh-6.0 homeserver.. I had to use linux-2.2.10
and the older raidtools-0.41.* toolset
- could NOT get teh newer raidtools to read the superblock
of the old /dev/md0 ( /home ) which had to remain intact
have fun
