Managed to partially lift the pool.

# zpool status tank
   pool: tank
  state: FAULTED
status: One or more devices could not be opened.  There are insufficient
         replicas for the pool to continue functioning.
action: Attach the missing device and online it using 'zpool online'.

I put a new HDD to 2 terabytes, but the pool does not see gpt/disk3 :(

What else recommend to restore the pool?
