What is the output of "gpart show" as well as "zpool status" I am
guessing that part of the disk is used for swap outside of zfs. gpart
show will list the gpart partitions that were created and zpool status
will show the devices that the zfs is created on giving a better picture
as to why you are only seeing 95G instead of the 128.
