Yes.

Well, to 'fail' the drive, you'ld have to physically pull the drive
from the chassis which will involve a power cycle unless you've got
hot-swap drives.  Of course, you should confirm that your system will
boot with the RAID in a degraded state and that rebuilding the RAID will
continue even if interrupted by a reboot.  gmirror(8) passes those
tests.  You do have to type some commands to get a mirror to rebuild
(examples are shown in the man page) unlike some hardware RAIDs where
simply inserting an unused disk is sufficient.
