I had previously been using fdisk/bsdlabel and setting up special= ly configured partition tables that would work with gmirror. This involved = faking the size of the c partition to make sure there was space for gmirror= to store its metadata. Now that I'm using gpart I'm wondering if any of th= is trickery is needed? Can I simply create my partitions with gpart then cr= eate mirrored partitions using these partitions? I've tried this and it see= ms to work fine but I'm just being cautious.
