Solved. gmirror had been set up with -h specifying the device, and
although the newer server used the same device names for its disks
(ad[46]) it assigned them to different hot swap bays. Once I switched
the disks everything came up fine.

Wouldn't it be more feasible in this situation to just glabel the disks
and mount them from /dev/<fstype>/<label> instead. Might make your life
easier in the future for swapping disks.
Example:
/dev/ufs/tmp on /tmp (ufs, asynchronous, local, gjournal)
/dev/ufs/usr on /usr (ufs, local, soft-updates)
/dev/ufs/var on /var (ufs, local, soft-updates)
