I had this problem on OmniOS where zdb couldn't open my rpool. The problem was caused by guid mismatch in zfs metadata versus actual guids of my disks. I guess this is a result of replacing broken hardware and shuffling disks between zpools...
The solution was to zfs detach one device of the mirror and zfs attach it back.

For whatever reason, the cache path is different on FreeNAS. They haven't patched zdb to know where to look by default.
Add -U /data/zfs/zpool.cache <POOLNAME> to all uses of zdb to get it to work.
For your example, the command would be: zdb -U /data/zfs/zpool.cache -b data
