I don't think so.  Unless it's been added recently,
p9p doesn't have prep.  But even if it did, the
subpartitions it creates wouldn't be visible to
Linux, so I wouldn't have any way to name them
for mirrorarenas.  At least that's the way I
understand it.  It's certainly possible I'm
mistaken, however.

BTW the reason it's p9p on Linux instead of an
actual Plan 9 install is that the particular
hardware I scrounged has one of those SCSI
controllers that can do RAID but has no driver
in Plan 9.  I did set it up before 9vx, though.
So maybe I could rethink some things and build
it all around that.  It'd be a little weird
because it's an archive server for UNIX machines
using vbackup.  So it runs vnfs to serve the
dumps.  But I suppose I could run venti in 9vx
and vnfs in Linux and, in principle, I think
it would work.  Or I could probably compile
vnfs under Plan 9 and run both under 9vx.
Sorry to ramble.  I'm brainstorming as I
write...
