Don't see my node running

  1. I followed tutorial. Running this cmd on my remote VPS
fuel-core run \
--service-name={my_svc_name} \
--keypair {my_secret} \
--relayer {my_relayer} \
--ip=0.0.0.0 --port=4000 --peering-port=30333 \
--db-path=~/.fuel-sepolia-testnet \
--snapshot ./fuel/chain-configuration/ignition/ \
--utxo-validation --poa-instant false --enable-p2p \
--reserved-nodes /dns4/p2p-testnet.fuel.network/tcp/30333/p2p/16Uiu2HAmDxoChB7AheKNvCVpD4PHJwuDGn8rifMBEHmEynGHvHrf \
--sync-header-batch-size 100 \
--enable-relayer \
--relayer-v2-listening-contracts=0x01855B78C1f8868DE70e84507ec735983bf262dA \
--relayer-da-deploy-height=5827607 \
--relayer-log-page-size=500 \
--sync-block-stream-buffer-size 30

It started syncing the chain for a while. Then wanting the process to run in the background so trying a few running-background cmd and kill the ssh connection a few times. Eventually when I reconnect to my vps using the same cmd “fuel-core run…” above, got this result:

3 - So the question is:
a. How to get the node up running?
b. How to get this process running in background properly? Tried to google, would be nice if you can list down details commands with expected response
c. How to test the result (by accessing from browser or any command from my local terminal)

Hi @KhaTruong123 ,

Can you try setting the ulimit on your system higher? And try again?

I’ll speak with the client team about the Height error, but the ulimit is something to try first.

Yo, seems like found the problem.
You need to run systemd to let the process running in the background. Seems like our official tutorial didn’t mention that and most likely your low-tech node operators (folks like me :smiley: ) are not aware of that command, especially when running the node through VPS, killing the session will bring down the process also.
Problem solved!
