i have an existing old-style glabel gmirror. a drive, ada0 failed. we
inserted a new drive as ada0. as the old drive is a teensie 80g drive
and the new is a 500g, we figured to create gm1, dump/restore to it, and
then swap out the old working 80g for another 500 and mirror away.
so i went to the handbook. 20.4.3 Creating a Mirror with an Existing
Drive does not seem appropriate as it assumes no source mirror and equal
sized drives.
so i figured to do the dance of 20.4.2 Creating a Mirror with Two New
Disks, but with one disk and then mirror back. but ...
# gmirror label -v gm1 /dev/ada0
Metadata value stored on /dev/ada0.
Done.
# gpart create -s MBR mirror/gm1
mirror/gm1 created
# gpart show mirror/gm1
=> 63 976773104 mirror/gm1 MBR (465G)
63 976773104 - free - (465G)
# gpart create -s BSD mirror/gm1s1
gpart: arg0 'mirror/gm1s1': Invalid argument
whoopsie.
clue?
