I've hit that one a lot. I am not aware of any way to fix it without reboot. In fact, in all of my experience, you don't even have a choice. You wait long enough (a few hours) and the system will become totally unresponsive, and you'll have no alternative but power cycle. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
