'zfs upgrade' unmounts file system first, which makes it hard to upgrade for example root file system. The only work-around I found is to clone root file system (clone is created with most recent version), change root file system to newly created clone, reboot, upgrade original root file system, change root file system back, reboot, destroy clone. -- Pawel Jakub Dawidek http://www.wheelsystems.com p...@freebsd.org http://www.FreeBSD.org FreeBSD committer Am I Evil?
