Well, first I'd like a problem report. The information I need is described both in the man page and at http://www.vinumvm.org/vinum/how-to-debug.html. In particular I'd like to see what the panic is. > I have no possibility to get new large disk now. > Should I try to remove plex usr.p1 ? Can you get two smaller ones? It's possible to mirror to plexes of different sizes, but obviously if something goes wrong beyond the end of the smaller plex, you're no longer resilient.
