I personally think this use case is a bit ... odd, anyway.
I have only request to those that manage GPT/GEOM/etc -- as I'm used to
doing multiple mdadm RAID components on Linux for maximum flexibility,
using gmirror upon multiple GPT partitions upon the same physical device
is OK with me. My only complaint is that recovery is very, very stupid. We
should by default detect and only rebuild ONE gmirror device at a time on
the same physical provider. You get nothing but a smokin' angry head if
you allow multiple to rebuild at the same time because it's fighting over
sequential writes all the way across the platters. It would also be nice
if gmirror rebuild could also be detected by fsck and fsck could either
hold off or gmirror could be paused until a consistent filesystem state
exists. It's probably best for the background fsck to go first so you can
get the system up and running, but then when it's finished gmirror should
continue.
Otherwise I have no issues with gmirror -- it does exactly the job I need
it to.
