I may be able to use multiattach with a cluster FS, though that complicates the setup a little bit. Thanks for the RDS suggestion. The main reason for trying to avoid it is laziness honestly, and cost. I need to share files other files across all servers, and since I already have SQLite databases, I was trying to kill two birds with one stone, and keep things simple. But RDS may is probably a better way to go in principle. For now I also want to avoid its cost.
