Whether I then detach and attach again doesn't matter, fsck will think /dev/vtbd1.eli is read-only until reboot. I recall there was some hack that allowed to fsck device even if it was open already, but only once. Maybe this is somehow related. You could try setting kern.geom.debugflags to 4 and see where g_access(9) is failing. -- Pawel Jakub Dawidek http://www.wheelsystems.com FreeBSD committer http://www.FreeBSD.org Am I Evil?
