I did that exact upgrade about 6 months ago....
I had to use the old mdadd/mdrun commands from the old raidtools...
Do not use the new raidtools if you value your old data
in upgrading from redhat-5.x to redhat-6.0.....
( lost my backup disks during my upgrade tests... not a big issue )
- note redhat-6.x also does additional reverse dns checks
and needs ver=2 for talking/mounting the older sun boxes too
am currently upgrading to redhat-6.1..... and so far... those older superblocks
still seems to be okay with the new redhat-6.1 (2.2.10) /etc/raidtab format/tools...
- am using hardware raid ( three 64Gb boxes ) + raid0 for mirroring/backups
w/ many 15Gb ide drives spanning a few servers ( daily, weekly, monthly )...
have fun "raiding"
