Most likely, at some point you tried to import both pools at once like
this:

    # zpool import vf2zpool1 vf2zpool2

What this actually does is rename vf2zpool1 to vf2zpool2 and then import
it.

The fix is to import vf2zpool1 under its correct name:

    # zpool import 15782797086784599572 vf2zpool1

then import vf2zpool2 as usual:

    # zpool import vf2zpool2

and everything will be back to normal.
