Homelab upgrade - "Modern" alternatives to NFS, SSHFS?

Hi all!

I will soon acquire a pretty beefy unit compared to my current setup (3 node server with each 16C, 512G RAM and 32T Storage).

Currently I run TrueNAS and Proxmox on bare metal and most of my storage is made available to apps via SSHFS or NFS.

I recently started looking for "modern" distributed filesystems and found some interesting S3-like/compatible projects.

To name a few:

• MinIO
• SeaweedFS
• Garage
• GlusterFS

I like the idea of abstracting the filesystem to allow me to move data around, play with redundancy and balancing, etc.

My most important services are:

• Plex (Media management/sharing)
• Stash (Like Plex 🙃)
• Nextcloud
• Caddy with Adguard Home and Unbound DNS
• Most of the Arr suite
• Git, Wiki, File/Link sharing services

As you can see, a lot of download/streaming/torrenting of files accross services. Smaller services are on a Docker VM on Proxmox.

Currently the setup is messy due to the organic evolution of my setup, but since I will upgrade on brand new metal, I was looking for suggestions on the pillars.

So far, I am considering installing a Proxmox cluster with the 3 nodes and host VMs for the heavy stuff and a Docker VM.

How do you see the file storage portion? Should I try a full/partial plunge info S3-compatible object storage? What architecture/tech would be interesting to experiment with?

Or should I stick with tried-and-true, boring solutions like NFS Shares?

Thank you for your suggestions!
