Re: [HEADSUP] zfs root pool mounting

    Going back in time a until the start of November didn't help. This
zpool get version for both of the pools is quite interesting -- in
particular, why is the value unset ("-")? I've provided the zdb -C
info as well (just in case) (interesting why things are ordered the
way they are in the zdb output -- not sure if it matters or not). I
unset cachefile on the zpool (set it to `none` before according to the
documentation's list of accepted values).
    I rebooted the box and still ran into mounting issues... Going to
try to keep on working on this for a couple more iterations before I
give up and move one of the drives to UFS or reformat with ZFS using
gjb's livecd.
Thanks,
