Thank you all for your input. The "set autoconfig, poweroff, move disks (or
replace
mainboard, which is quicker), power-up, dump labels, adjust raidN.conf" is more
or
less what I had in mind once I read those portions of raid(4) and raidctl(8).
I still plan to map mainboard SATA connectors to device names on both the
current
and stopgap systems. It may be warm enough today to get the machine to behave
long
enough to make sure the system (10.1_STABLE) is up to date and has my minimally-
tweaked GENERIC_R5RS kernel in place (the machine rebooted before it could copy
that kernel the last time I tried).
I have only the one RAID set. The components have an ordinary disklabel with
one
slice of type RAID covering the entire disk. The RAID is configured as RAID-R
(RAID-5
w/rotated sparing). The blocking configuration is suboptimal as I was quite
naive when
I set it up long ago. The configured raid uses a GPT and shows up as {,r}dk0.
The whole thing needs replaced and I've been grooming a system, but haven't been
able to get new disks...
