Some simple tests showed, that loading geom_label as a module before or after geom_mirror does not trigger the problem here. >How-To-Repeat: I found the problem mentioned on the current mailing-list at http://unix.derkeiler.com/Mailing-Lists/FreeBSD/current/2007-06/msg00448.html where Kazuaki ODA shows the follwing example: # dd if=/dev/zero of=/var/tmp/disk1.img bs=1k count=1k # mdconfig -a -t vnode -f /var/tmp/disk1.img md0 # glabel create <LABEL_NAME_ENCODED_OTHER_THAN_UTF8> md0 # glabel list glabel: Cannot get GEOM tree: Unknown error: -1 >Fix: As a work around you can avoid non-ascii characters in volume labels or do not use geom_label at all. >Release-Note: >Audit-Trail: >Unformatted:
