Zpool import - one or more devices is currently unavailable

When attempting to import a zpool with -m (also -F and -f and combinations thereof), I receive: "cannot import 'tank2': one or more devices is currently unavailable"

I believe the missing devices (below) were a log and a cache vdev. The mirrored log device files are available and for other pools that did not have an additional vdev missing, an import with -m worked.

Is there a way to recover/import?

sudo zdb -e tank2 results in:
