Hello,
I'm getting the Error: Contract not deployed after cloning private geth network from one server to another.
Steps to reproduce:

Private geth network is running on server1.

Deploy contract using truffle and make a few transactions.

Stop geth n/w of server1 and copy its entire directory (accounts.txt, boot.key, genesis.json, node's password.txt along with its directories keystore and geth) and paste to server2

Change in the geth configuration --rpcaddr 'xx.xx.xx.xx' with private IP of the server2.

Bring up this geth network clone of server1 on server2 (it is able to successfully seal new block, mine potential block, and commit new mining work)

Interact with contract on server2.

Error: contract not deployed

Restart the stopped geth n/w server1 (it is able to successfully seal new block, mine potential block, and commit new mining work)

Interact with contract on server1.

Error: contract not deployed
Expectation:
Restarting the geth n/w on server1 should not cause any data loss.
Should be able to interact (get the transactions performed on server1 as the data should be present in chaindata) with the contract on server2.

Note: I was able to migrate a test geth n/w successfully for a n/w running from past 2 days. After this successful operation, I was migrating this geth n/w which was running from past 7 months which is failing now with error contract not deployed. Will it sync/heal itself if its up for a long time? What are the correct ways to restart and migrate the n/w with huge chaindata. Any documentation would be much appreciated.

Thanks

Hello Everyone,
I just set up an eth node on my new rpi4
and im running bitvise on my HP for ssh
So everything was up and running last night, but after i booted my personal pc this morning im having a hard time getting back into the terminal and checking the status of the mine, does anyone have any tips on checking progress in a new terminal?
i can’t even use the jobs command to make sure the node is running (but i know its running bc htop)

Hi! I tried to use www.ethercluster.com/etc to test my dapp and initiate a transaction. But it fails with http-400 errors. Does anyone know if ethercluster.com is a READ-ONLY API that does not allow to issue transactions? Thank you in advance!

hi - I'm running a multi-chain test with 2 embedded geth instances (seperate chain ids, no peering, functionaly equivelant to --dev. Memory only store, etc). I'm running into some issues around getStateObject being nil in tx pool for an address that returns the correct balance w/ BalanceAt() over in proc rpc. I'm just wondering if there's a global I'm not seeing where 2 Node's in the same instance would use the same global variable

@BlockXXebu

i have a question on pendingTransactions API in the core code
This line on the geth code

https://github.com/ethereum/go-ethereum/blob/13bc9c0c6e74f36f6f8039d0041fb93740d25a4a/internal/ethapi/api.go#L1805

Why is this API only display the pending transactions of the accounts local to the node? Whats the reasoning behind this?

I'm having trouble getting my Ethereum Classic "core-geth" Full Node running on a Raspberry Pi4 64bit. Using the latest ETCLabs core-geth build compiled on the RasPi4.

Is there a genesis.json file to init the node for Ethereum Classic?

Anyone know how to fix this issue with geth, looks like some kinda data coruption.

The original problem was this:

But I saw on another forum where someone used removedb to delete the ancients folder.

How do I rebouild the ancient folder?

Here is the correct difrectory:

I think I have to resync geth again, is there an image of the db I can download. Otherwise its going to be a week of downtime/slahing. or is it possible to pause staking in that time while I fix this error.
