Restore snapshot with full state history

Goal

This procedure restores an existing snapshot with full history, so the node can become active in the blockchain.

Before you begin

• Make sure Wire core is installed.
• Learn about Using Nodeop.
• Get familiar with state_history_plugin.

Steps

1. Get the following:

   • A portable snapshot (data/snapshots/snapshot-xxxxxxx.bin)
   • The contents of data/state-history
   • Optional: a block log which includes the block the snapshot was taken at. Do not include data/blocks/reversible.

2. Make sure data/state does not exist

3. Start nodeop with the --snapshot option, and the options listed in the state_history_plugin.

4. Do not stop nodeop until it has received at least 1 block from the network, or it won't be able to restart.

Notes

If nodeop fails to receive blocks from the network, then try the above using net_api_plugin. Use clio net disconnect and clio net connect to reconnect nodes which timed out.

[[caution | Caution when using net_api_plugin]] | Either use a firewall to block access to http-server-address, or change it to localhost:8888 to disable remote access.
