Run a New Archive Node

[timolson]

I am trying to start up a new Nitro archive node (classic not required) Or do you call that a "full" node? I need the full blockchain history back to the start of Nitro.

Nitro fails with any init option I try other than --init.latest=pruned but my understanding is that pruned nodes do not contain enough history for my use case.

When I try starting with --init.latest=archive or --init.latest=genesis there are failures related to the unavailability of snapshots.

When I try starting with --init.url="https://snapshot.arbitrum.foundation/arb1/nitro-archive.tar" it fails to find the manifest txt.

I do not have an existing archive node from which to take a snapshot, and have had no success trying to start from genesis either.

I have found no up-to-date documentation on how to run a full node. Only pruned nodes seem to work.

Could you please point me in the direction of how to start & run a new node that can serve the entire history since Nitro?

Although there is definitely a Pebble database for genesis, it does not find it. However, using --init.url=https://snapshot.arbitrum.io/arb1/nitro-genesis-pebble.tar seems to work.

Hey @timolson thanks for flagging the issue. I think I have fixed it, started up a new nitro node with the --init.latest=archive flag and saw this log line

Could you give it a go and let us know if this works for you now?
