# Contributing Storage

If your host machine can be reasonably sure of being online most, if not all, of
the time, and has 100GB or more of unused drive space you'd like to contribute
to the network, then this document is for you.

## Create daemon.yml

First, if you haven't already, [create a `daemon.yml`
file](../user/creating-a-daemonyml-file.md). This will be used to
configure your `cryptic-net daemon` process with the storage locations and
capacities you want to contribute.

## Edit daemon.yml

Open your `daemon.yml` file  in a text editor, and find the
`storage.allocations` section.

Each allocation in the allocations list describes the space being contributed
from a single physical drive. If you only have one drive then you will only need
one allocation listed.

The comments in the file should be self-explanatory, but ask your admin if you
need any clarification.

Here are an example set of allocations for a host which is contributing space
from two separate drives:

```
storage:
  allocations:

    # 1.2 TB are being shared from drive1
    - data_path: /mnt/drive1/cryptic-net/data
      meta_path: /mnt/drive1/cryptic-net/meta
      capacity: 1200
      api_port: 3900
      rpc_port: 3901
      web_port: 3902

    # 100 GB (the minimum) are being shared from drive2
    - data_path: /mnt/drive2/cryptic-net/data
      meta_path: /mnt/drive2/cryptic-net/meta
      capacity: 100
      api_port: 3910
      rpc_port: 3911
      web_port: 3912
```

## Setup Firewall

You will need to configure your hosts's firewall to allow traffic from
cryptic-net IPs on the ports you specified in your allocations.

## Restart the Daemon

With the `daemon.yml` configured, you should restart your `cryptic-net daemon`
process.

## Further Reading

cryptic-net uses the [garage][garage] project for its storage system. See the
[Managing Garage](managing-garage.md) document for more
information on how to interact directly with the garage instance being run by
cryptic-net.
