If you create a BSD scheme partition inside a geli encrypted provider like so: geli init -b -v -a hmac/sha512 -e aes-cbc -l 256 -s 4096 /dev/ad0p1 geli attach /dev/ad0p1 gpart create -s BSD ad0p1.eli gpart add -s 1g -t freebsd-ufs ad0p1.eli then you try to newfs, you get an error: # newfs -U /dev/ad0p1.elia newfs: can't read old UFS1 superblock: read error from block device: Invalid argument >How-To-Repeat: geli init -b -v -a hmac/sha512 -e aes-cbc -l 256 -s 4096 /dev/ad0p1 geli attach /dev/ad0p1 gpart create -s BSD ad0p1.eli gpart add -s 1g -t freebsd-ufs ad0p1.eli newfs -U /dev/ad0p1.elia >Fix: The workaround for this bug is to dd data to the provider before using newfs: dd if=/dev/random of=/dev/ad0p1.elia bs=8m After that, newfs works as it should. >Release-Note: >Audit-Trail: >Unformatted:
