This can occur if the location of the end of the partition has
changed locations. This could be due to the partition actually
shrinking or if more than one partition references the same
starting block, but different ending locations. Check your
partition configuration in format and debug with "zdb -l"
When you can see all 4 labels, then you should be able to
import.
