/dev/mirror/gm0s1e on /var (ufs, local, soft-updates)



i want to upgrade consumer ada1 to the same size/geometry as ada0 and
to extend /dev/mirror/gm0s1f to use all rest available unused space ...

so, how can i do that correct way, please?

am i correct to think it can be done such way?

1. to remove small ada1 and install new hdd (equal to ada0)

2. gmirror remove gm0 ada1
   gmirror forget ada1

   growfs /dev/mirror/gm0s1f
   
   gmirror insert gm0 ada1


thanks in advance
