As you see I have ada{0-2}p3 labeled as disk{0-2}
All labeled partitions have valid gpt id but zfs partitions don't have
accesible gpt label in /dev/gpt:

As you see labels was firstly seen, but removed at the end. I tried to
set blank label and then correct one again, but no luck.
Any ideas what's possibly wrong here?
Problem appeared after my pool was broken and I imported it from some
boot CD to fix this by "import -F".
Now I have unreadable output from zpool commands, like this:
