But I'm confused about the gpart thing I did on the original disks.
$ gpart show
=> 34 156301421 ad4 GPT (75G)
34 128 1 freebsd-boot (64K)
162 8388608 2 freebsd-swap (4.0G)
8388770 147912685 3 freebsd-zfs (71G)
=> 34 156301421 ad6 GPT (75G)
34 128 1 freebsd-boot (64K)
162 8388608 2 freebsd-swap (4.0G)
8388770 147912685 3 freebsd-zfs (71G)
Do I repeat this gpart section on the new disk(s) before putting them in
the rpool (one at a time). Is it compatrible to putting the solaris
bootcode on disk before attaching them to a rootpool and resilvering? I
want to expand my rootpool but am a little confused about the right
procedure.
