For the archives, from a private exchange: Zdb(1M) is complicated and in-flux, so asking on zfs-discuss or calling Oracle isn't a very onerous request IMHO. As for recovery, see zpool(1M): > zpool import [-o mntopts] [ -o property=value] ... [-d dir | -c > cachefile] [-D] [-f] [-R root] [-F [-n]] pool | id [newpool] [...] > -F > Recovery mode for a non-importable pool.
