both got the disklabel RAID part,
shall i do further checks ?
# bioctl -c 1 -l /dev/sd0a,/dev/sd1a softraid0
softraid0: trying to bring up sd2 degraded
softraid0: sd2 was not shutdown properly
softraid0: sd2 is offline, will not be brought online
softraid0: trying to bring up sd2 degraded
softraid0: sd2 was not shutdown properly
softraid0: sd2 is offline, will not be brought online
I wouldnt like to blow the whole array ! sd0a should be in perfect
condition but unsure about sd1a, i probably need to bioctl -R sd1
