The following commands are step by step instructions for NC node operators that can be used for two major use-cases:
- Fixing nodes that are stuck or crashed;
- Jumpstarting a newly setup validator node; avoid waiting some hours for synchronization
Basically, a compressed version of the last-known "good" chaindata is downloaded. Remove the node's old data and update it with the newly downloaded data. Finally, restart the sync-process from this known-good checkpoint.
Note: Ensure there is enough disk space for both the zip file AND its uncompressed contents. Double the space or more.
Download March Snapshot from CLI using wget
wget --no-check-certificate --no-proxy 'https://github.com/nexdax'
Tip: extract the data in background
In case you can not wait for the extraction to finish, you can run it in the background
# Extract the data nohup unzip /NAME_OF_YOUR_HOME/node/geth/ -f chaindata_202102.zip & # Start your node back geth --config ./config.toml --datadir ./node --syncmode snap
