Hi Mark, AFAIK (and people will correct me if I'm wrong), there is no ZFS support whatsoever at boot unless you've asked zfs_load="YES" in your loader.conf and installed the zfs bootcode. You say you have a raidz2 so I take it your server was working before ? The question I'm asking here is: before what ? Did you upgrade from 8.0 to 8.1 ? It may not be the best piece of advice you'll receive but I would try the following: 1/ a verbose boot, you never know. 2/ unplug a disk, try to boot, rinse/repeat until it works, to identify a potentially *very* faulty drive. _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[email protected]"
