[ZFS] Unable to migrate to ZOL

Aloha

I have a ZFS pool on ~~freebsd~~ FreeBSD and want to migrate to ZOL but I have some problems.

This is my pool:

Code:

 zpool status

I can export and import the pool by GPT or gptid but not from diskid.

Code:

 zpool import -d /dev/gpt
 pool: data
 id: 6443248701440510437
 state: ONLINE
 action: The pool can be imported using its name or numeric identifier.
 config:
  data ONLINE
 gpt/disk1 ONLINE
 gpt/disk2 ONLINE

gptid:

Code:

 zpool import -d /dev/gptid
 pool: data
 id: 6443248701440510437
 state: ONLINE
 action: The pool can be imported using its name or numeric identifier.
 config:
  data ONLINE

 gptid/7bf1c36b-e9ba-11e2-a573-3cd92b0b000e ONLINE

And from diskid:

Code:

zpool import -d /dev/diskid/
 pool: data
 id: 6443248701440510437
 state: ONLINE
 status: One or more devices contains corrupted data.
 action: The pool can be imported using its name or numeric identifier.

I try also zdb -e which was running for about 20[]hours and got no error from it. When I try from ZOL I get corrupted data from both disks.

Thanks in advance
