How to expose a glusterfs server?

It’s easy to plug a hard-drive and expose it as a NAS, through SMB and/or NFS.

To avoid this NAS to become a SPOF, I’d like to expose it through instead of NFS. It would allow the data to be replicated on some other devices, and the clients to be transparently switched from one device to another one.

I did not find any package for glusterfs on Turris OS (or OpenWRT).
It’s probably possible to do that through a LXC container, I suppose. But it would be so simpler to handle it directly on Turris OS.

Anybody tried such thing?

My goal is to avoid a SPOF, as this data would be the persistent volumes of a kubernetes cluster (hosted on other devices of the local network)
