So I have a
validator_count of 2, and 1 as
minimum_validator_count. My validator is always online. I had my friend make another validator, had it enter the active validator set, and then join in as a validator, but they had to shut down their machine. To my surprise, I see that now my chain has stopped finalizing blocks but it goes on producing blocks normally. All functions work.
I have 2 questions:
- why does this happen?
- And how can we fix this?
Edit: Looking around I've found this : https://polkadot.js.org/docs/substrate/extrinsics/#grandpa as a way to reinitialize the grandpa authority set (if I understand correctly), which might have been corrupted by 1/2 validators leaving.
I've also noted that the
roundState() rpc call errors out with :
GRANDPA RPC endpoint not ready. An explanation for this would be welcome.
Edit #2 : I've already fixed this using the tx.noteStalled. However I'd still like an answer to the first question. i.e why does this happen? Is it because of BFT and 1/2 validators turning out faulty?
