Issue Description

I have been trying to deploy an OP stack rollup. I have succeeded in the past, but today when I try to restart my rollup, something wrong happens with starting the proposer(something is wrong with the l2oo I suppose, as I haven't restarted the rollup for about two weeks), so I try to go over the whole tutorials again and redeploy another rollup. But it seems that the op-geth is always linking to the main net which the chain ID is 1, I have no idea where to change this. The op-node genesis file only have the option to change the L2 chain ID I suppose? And this causes the problem of starting op-node, because the log says incorrect L2 RPC chain ID.

Links to the tutorial： https://docs.optimism.io/builders/chain-operators/tutorials/create-l2-rollup

Additional Information

When I create the genesis file following the tutorials, it says head block is not reachable. And there is also something wrong with this error:sers\86186\op-geth\datadir\geth\chaindata\ancient\chain readonly=false
Fatal: Failed to register the Ethereum service: incompatible state scheme, stored: path, provided: hash
So I just deleted the chain data folder. I think my database must have been spoiled, but I have no idea how to totally get rid of the old one. I deleted the whole op-geth and reinstall it, but it still says INFO [08-11|19:27:16.075] Opened ancient database database=C:\Users\86186\op-geth\datadir\geth\lightchaindata\ancient\state readonly=false. How can I clear all the ancient database and restart?

Hello!

To help clarify your situation, could you please specify:

1. Which L1 chain are you trying to deploy your rollup on? (Ethereum mainnet or Sepolia testnet?)
2. What chain ID are you aiming to use for your L2 rollup?

[zhaozaao]

Hello！ I am trying to deploy on the sepolia testnet. The L2 chain Id is the default 42069.

[Chomtana]

It should be about the genesis file generation where it says head block is not reachable

Do you have a full log on this?

[zhaozaao]

If I delete the datadir/geth folder, op-geth can start normally, but op-node still can not because of the chain ID

[zhaozaao]

I have used a alchemy RPC linked to the Sepolia, why would the op-geth connected to the mainnet?

[sbvegan]

Hey @zhaozaao, can you please edit the original post with the following information:

• op-node version and runtime configuration
• op-geth version and runtime configuration
• link to the tutorial section you followed to generate the genesis.json

[zhaozaao]

Hi @sbvegan , I have edited the original post.

[zhaozaao]

I solve this problem by using state schema as hash when creating the genesis file.
$ ./build/bin/geth init --datadir=datadir --state.scheme hash genesis.json
