I think that is unlikely. If you type status at this point, does it show all of your drives ONLINE? > ZFS: i/o error - all block copies unavailable > ZFS: can't read MOS > ZFS: unexpected object set type lld > ZFS: unexpected object set type lld I'm trying to find the "can't read MOS" issue now. This is pretty much the first thing that we try to get once all of the drives are online. I can't produce this issue locally, so I'm trying to get enough debugging to see what is going on with the root block pointer. Basically, if we can't read the MOS, we aren't going to read anything. Thanks to ps@, we have a wrapper program that lets us debug this from userland which helps a lot. I just wish that I could figure out how to replicate the problem, but I guess if I could do that... we could figure out how to fix it. robert. > FreeBSD/i386 boot > Default: z:/boot/kernel/kernel > boot: > ZFS: unexpected object set type lld > > FreeBSD/i386 boot > Default: tank:/boot/kernel/kernel > boot: > > FreeBSD/i386 boot > Default: tank:/boot/kernel/kernel > boot: > _______________________________________________ > freebsd-current@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-current > To unsubscribe, send any mail to "freebsd-current-unsubscribe@freebsd.org" -- Robert Noland <rnoland@FreeBSD.org> FreeBSD
