zroot is the system pool, m0 is the secondary data pool, v0 is a pool of virtual disks that I created for testing. When executing the order zpool import to see what pools i can import i get this output:

ZFS WARNING: Unable to attach da0
ZFS WARNING: Unable to attach da2
ZFS WARNING: Unable to attach da1
no pools available to import

I can understand that you can't attach those three disks since they belong to the m0 pool, but why are these warnings appearing about those three disks?

I don't get it, is it a normal output from zfs import?

Thanks.
