Lotus: Upgrades

This guide will show you how to safely upgrade a Lotus node to a newer version.

Installing an update

Usually, if you are updating Lotus, it as simple as rebuilding and re-installing the software after pulling the latest state for the chosen branch and repository. You can do that with:

git pull
git checkout <branch or tag>

Once the new version is checked-out, rebuild and re-installas explained in the installation guidein the guide.

You can verify your current version with:

lotus --version # for the lotus binary
lotus version   # for the currently running daemon

You will need to stop and start the daemon again after installing the new version.

Nuking the Lotus data

In some occasions, for example in the case of a network reset (where an existing chain is rebooted from scratch), you will need to delete the lotus configuration folder located at ~/.lotus (or, if manually set, at $LOTUS_PATH):

rm -rf ~/.lotus # or $LOTUS_PATH

WARNING

This will delete all chain data and wallets! Be very careful with this on mainnet if you have FIL in your wallets!
