Theres a file /boot/zfs/zpool.cache which is, I think, the equivalent

You can do a forced export - as long as the system doesnt think
the pool is imported then an import will go looking. I made a
similar mess of my drives the first time I changed discs oover, and I
also didnt know about the import/export trick. But since then I
have used iit every time I have got into trouble and it has always
worked for me.
