The "bioctl: BIOCCREATERAID: Invalid argument" and "softraid0: invalid
metadata format" messages are a result of having a metadata mismatch with the
chunks that you are trying to assemble - this can happen for a range of
reasons (e.g. you try to bring a RAID 1 volume up as a RAID 0 volume).
Since you mentioned that one of your chunks is "offline" (since you
disconnected it), the two chunks will now have different on-disk metadata
versions - the metadata version will have been increased on the "online"
chunk as soon as a problem was noticed. This obviously prevents you from
bringing up two devices that are out of sync with each other.
The solution to this problem (assuming you want to start from scratch) is to
either zero the first 1MB or so of the device, or use the '-C force' option
with bioctl. Alternatively you should be able to rebuild onto the offline
device by using bioctl's -R option.
