It's on GitHub but the license seems custom and reads line more of a source-available license:

    3.3) Without prior written consent of LICENSOR or an authorized partner, LICENSEE may not:
    - use, copy or distribute the LICENSED SOFTWARE except as provided for under sections 3.1 and 3.2.
    - provide commercial turn-key solutions based on the LICENSED SOFTWARE or commercial services for the LICENSED SOFTWARE to any third party.
    - rent or lease the LICENSED SOFTWARE and DOCUMENTATION to any third party.
    - modify, adapt, or translate the LICENSED SOFTWARE for any third party.

Also, the "community edition" is pretty much useless on its own:

    3.4) The following optional functionalities and features of the LICENSED SOFTWARE are declared as enterprise features:
      - Resiliency: (a) Mirroring; (b) High Availability
      - User management: Quota Enforcement
      - Data management: (a) Storage Pool; (b) Remote Storage Targets (RST); (c) Copy; (d) Watch; (e) Index; (f) Balance
    
    All enterprise features are disabled by default. LICENSEE may not modify or delete mechanisms for licensing enforcement of enterprise features from LICENSED SOFTWARE.

So yeah, it being on GitHub doesn't make it any interesting. If I ever need something like this I'll just use good old Ceph.
