I have a RAID set that autoconfigures as raid4, and my root partition
is raid4a. I want to renumber it to raid0 insetad of raid4. I could
use a hex editor on the raw disk, but I would prefer a less dangerous
I tried the obvious, like:
# boot to a non-raid root partition.
# autoconfig finds and confuigures raid4.
# mark raid4 as not autoconfigurable, and unconfigure it now
raidctl -A no raid4
raidctl -u raid4
# configure a raid0 device, using a config file that
# refers to the same underlying devices that were used
# for the unwanted raid4 device.
raidctl -c /etc/raid0.conf raid0
# mark raid0 as autoconfigurable and a root candidate
raidctl -A root raid0
# see if it worked
raidctl -s raid0 | grep "Last"
but after all that "raidctl -s raid0" still reports "Last configured as:
raid4", and on the next boot the device is again configured as raid4.
