I have run up a 6 X 4.1Gb RAID5 box with raidtools 0.9 on a NCR53C810a
controller.
Looking at the mdstat and resyncing all works fine. Moved some data onto Raid.
Then I moved the box to a Server running NCR53C860 controller.
It claimed that md0 was/had an Invalid argument.
I cannot raidstart (see below) or even force a mkraid...
"raidstart"
/dev/md0: Invalid argument
"mkraid"

mkraid: aborted, see the syslog and /proc/mdstat for potential clues.
"mdstat"
Personalities : [4 raid5]
read_ahead not set
md0 : inactive
md1 : inactive
md2 : inactive
md3 : inactive
I can see the /dev/sda ... /dev/sdf and even run fdisk or mke2fs on them.
When I try to mkraid it aborts!
HELP
