Hi!
Have a 5.4 currently installed in sd0 and want to build a softraid1 to
use
the disk in conjunction with a secondary sd1.
I know a way to build the raid at installation point, but not sure how
to
do it after the installation without reinstalling. Is possible?
You cannot "convert" an existing FFS filesystem into a softraid(4) array
without backup and restore steps, because the array stores its metadata
in the leading sectors. The FFS filesystem within a RAID virtual sd(4)
device has a different LBA starting sector on the backing storage.
