Archive Node
This guide will cover setting up an archive node for the Oasis Network. Node started in archive mode only serves existing consensus and runtime states. The node has all unneeded consensus and P2P functionality disabled, therefore it will not participate in the network. Archive nodes can be used to access historic state which is pruned in dump-restore network upgrades.
Prerequisites
Archive node requires a pre-existing oasis-node state.
Configuration
Archive mode can be enabled by using the mode setting.
This will configure the given node to act as an archive node.
# other settings omitted ...
mode: archive
Keep other settings unchanged from the full-node. For example in order to serve archived runtime state, the node needs to have the runtime configured and have the state present.
Starting the Oasis Node
You can start the node by running the following command:
oasis-node --config /node/etc/config.yml
Archive node status
The mode field is currently unavailable in the control status output. It will be included in an upcoming release.
To ensure the node is running in archive mode, run the following command:
oasis-node control status -a unix:/node/data/internal.sock
Output should report archive consensus mode status:
{
// other fields omitted ...
"mode": "archive",
// ...
}
