I have installed FreeBSD 11 on a spare disk. I can mount my old pool
with "-o altroot=/mnt" without any trouble. But for some reason,
/dev/diskid is gone. I wonder why it is so and I want it back.
In the following output the spare disk I have installed FreeBSD 11 on
is "ada0" and "zroot" is a new pool. "tank" is my old pool, which is
mirrored on "ada1" and "ada2". I plan to move my data to the new pool
and then remove the disks one by one from the old pool to add them to
the new. The freebsd-boot partitions on these disk are too small
nowadays anyway. Thus, repartitioning them sounds like a good idea.
Thanks,
Erwan
