You will need to stop Geth, [perform a manual process to prune its database](https://gist.github.com/yorickdowne/3323759b4cbf2022e191ab058a4276b2), and restart it to remove this junk. During this time, your node will be offline, and staking penalties will start accruing. [The rescue node project](https://rescuenode.com/docs/) can be a good solution for stakers to prevent or lower downtime and penalties. Pruning Geth also needs around 80 GB of free space to begin with on Mainnet. If you don't have that free space, you could try to delete your consensus client database to make enough room for it and resync your consensus client using [a checkpoint sync endpoint](https://eth-clients.github.io/checkpoint-sync-endpoints/). The new [path state scheme (PBSS)](#resyncing-with-a-different-configuration) is an interesting configuration alternative for long-term low disk usage. -With **Nethermind**, you have [different configurations that enable online pruning](https://docs.nethermind.io/fundamentals/pruning) where your client is still able to serve its normal operation and clean its database at the same time. There is a manual process where you can trigger the pruning process. There is one based on a database size threshold. There is one based on a remaining storage space threshold. In any case, you are going to need around 220 GB of free space to begin that pruning process on Mainnet. A good strategy is to set the automatic pruning configuration to trigger when you are slightly above that 220 GB of remaining free space. This implies that you are effectively reserving that space exclusively for pruning. +With **Nethermind**, you have [different configurations that enable online pruning](https://docs.nethermind.io/fundamentals/pruning) where your client is still able to serve its normal operation and clean its database at the same time.
