Fehler:
############
Die Disk c1t0d0 brachte Fehler und sollte proaktiv getauscht werden.
Beim Tausch verabschiedete sich dann auch der Slice 3 (/var) der zweiten Spiegelhaelfte.
Der Sync brach einfach ab:

# metattach d30 d31
d30: submirror d31 is attached
# while true; do metastat | grep %; echo; sleep 10; done
    Resync in progress: 3 % done

    Resync in progress: 5 % done

    Resync in progress: 6 % done

    Resync in progress: 8 % done

--> Dat wars dann ...:-(

Beide Spiegelhaelften stehen nun im Maintenance Mode:
(Ausgabe leider nicht mehr verfuegbar)
