A shot in the sky: try "format", select the disk, enter "type".
It is possible that the old and new disks were auto-detected as
different types (i.e. I had two identical drives, one attached
and formatted in LegacyIDE mode, then another attached as native
SATA, which were recognized as different types with different
cylinder size - 16065 "blocks" vs. 12048 or something like that).
Selecting a disk type same as the existing drive allowed me to
partition the new one identically to the older one and mirror
the rpool. Perhaps this would help you too :)
