What is Zpool export?
The manpage for “zpool export” states: Exports the given pools from the system. All devices are marked as exported, but are still considered in use by other subsystems. The devices can be moved between systems (even those of different endianness) and imported as long as a sufficient number of devices are present.
What does Zpool Import do?
ZFS enables you to export the pool from one machine and import it on the destination machine, even if the machines are of different endianness. For information about replicating or migrating file systems between different storage pools, which might reside on different machines, see Saving and Restoring ZFS Data.
When do you need to use zpool export F?
It’s meant for situations when you know you are moving a zpool somewhere by moving its physical media. If you need to import a pool that wasn’t properly exported, for instance because the server it was in died, you can simply use zpool import -f. Thanks for contributing an answer to Server Fault!
How to import a dozer pool in ZFS?

Attach the missing devices and try again.
How to import a pool with a missing log device?
By default, a pool with a missing log device cannot be imported. You can use zpool import –m command to force a pool to be imported with a missing log device. For example: # zpool import dozer pool: dozer id: 16216589278751424645 state: UNAVAIL status: One or more devices are missing from the system. action: The pool cannot be imported.
Can a ZFS pool be imported under an alternate root?
ZFS is not a native cluster, distributed, or parallel file system and cannot provide concurrent access from multiple, different hosts. Pools can also be imported under an alternate root by using the –R option. For more information on alternate root pools, see Using a ZFS Pool With an Alternate Root Location.
