It appears to be using 512 sector size to calculate the number of sectors to allocate even when the sector size is not 512. >How-To-Repeat: gnop create -S 4k <disk or partition> gpart create -s GPT <gnop'd disk or partition> gpart add -s 512M -t freebsd-swap <gnop'd disk or partition> gpart will create a 4GB partition instead of a 512M partition >Fix: >Release-Note: >Audit-Trail: >Unformatted:
