Rollback and Recovery Guide

If an upgrade fails or a node crashes, rolling back to a previous stable state is necessary. You can follow these steps which provide steps for safe rollback and recovery. First, stop the Node, using the following command:

docker stop "$CONTAINER_NAME"

Now you are required to restore the Last Working Snapshot.

If the latest snapshot is corrupted, restore the snapshot using the following command:

./manage_supra_nodes.sh sync validator <host_supra_home> <network>

For RPC nodes, use the following command:

./manage_supra_nodes.sh sync rpc <host_supra_home> <network>

Now you can restart and start monitoring the Logs using the following command, to make sure the rollback was successful:

./manage_supra_nodes.sh start validator <container_name> <host_supra_home> tail -f <logs_root>/supra.log
