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... Thanks, BLS
