i'm trying to encrypt my external hard drive and am following the guide at https://www.freebsd.org/doc/handbook/disks-encrypting.html
with UFS, i have no problems creating the filesystem. all works as expected.
however, i wanted to use ZFS instead: when i type "zpool create backup /dev/da0p1.bde" the CPU usage goes through the roof (system CPU according to top), and eventually the whole computer becomes unresponsive and locks up. i've tried it multiple times with the same results.
# gpart show da0
=> 40 7814037088 da0 GPT (3.6T)
40 7814037080 1 freebsd-zfs (3.6T)
7814037120 8 - free - (4.0K)
# dmesg | grep da0
da0 at umass-sim0 bus 0 scbus9 target 0 lun 0
da0: <TOSHIBA MD04ACA400 0> Fixed Direct Access SCSI-6 device
da0: Serial Number X4RGK50ZFSBA

but that seems to be my mistake. i hadn't done a "gdbe detach /dev/da0" :)
