Okay so:
1. I have booted to single user and made zfs read-write.
2. I tried to rollback a snapshot of zfs/usr/home that did not help.
3. I have exported zfs/usr/home to /var/bkp/home.zfs.
4. Then imported home.zfs to zfs/usr/home2.
5. Removed zfs/usr/home.
6. zpool status -v resulted in permanent error in <0x4b>:<0x0> :-(
7. Tried zpool scrub zfs... but after some time machine hanged unresponsive.
8. Hard power off.
9. Power on -> single user.
10. zpool status did not show any problems on zfs now.
11. zpool scrub completed with no problems and no problems are reported.
12. I have renamed zfs/usr/home2 to zfs/usr/home.

smartcl cannot query /dev/nda0 so I have to find iso with disk vendor
tools just to make sure disk is fine.

So far so good :-P
