The author of that thread replied that "zdb -bcsvL -e poolname" is unrelated to being able to import it read-only and in the OP he meant that he couldn't import it as read-write. I think the zdb docs basically say that that command just verifies the checksums on all the blocks. Now it says:
> 316G completed ( 19MB/s) estimated time remaining: 125hr 45min 14sec
if that zdb command doesn't check metaslabs I guess it would complete no-problem if there's no checksum mismatches.

I'm using a Lubuntu ISO from years ago, and if I can, it's probably better to use Debian because that's more up-to-date. When I SSH in it says "Welcome to Ubuntu 14.04 LTS (GNU/Linux 3.13.0-24-generic i686)".
