The -c flag creates a volume - if these are chunks have no metadata then it
will create new metadata, otherwise it will reassemble the volume from the
existing metadata.
DO NOT use -C force unless you want to completely reinitialise the metadata
for the volume - in the case of a crypto volume you will generate new
metadata with new disk keys, rendering your existing data unreadable.
The error message you are getting is telling you that sd1a is already in use -
bioctl softraid0 will probably tell you where it is being used (your volume
is either already assembled, or it is part of another volume).
