Looks interesting (this page has a slightly more in-depth description of what beadm tries to achieve for the layman like me that doesn't use *Solaris: http://www.linuxquestions.org/questions/*bsd-17/howto-zfs-madness-beadm-on-freebsd-4175412036/ ). > Proper zdb -l usage was described in the "HEADSUP" posting. > It's also available in zdb(8). zdb -l should be used with > disks/partitions/etc, > not with pool names.

Ok. That's sort of what I'm trying. Given that I didn't do a *ton* of customizations, I might just tar up the root pool's contents and basic configuration, wipe it out, and try creating a new one from scratch and restore the contents after the fact. However, thinking back I could turn on terse debugging in ZFS after building it with that (I've done it once before -- forgot about it until now). That would probably be the best way to get the official "story" from ZFS as to what it thinks is going south when importing the pool.
