Is there a lightweight storage solution that makes shared storage easy without needing a NAS? I’m looking for something that isn’t necessarily highly available. I’m looking to be able to shift services around without having the complexity and overhead of Ceph. My current option is Unison which isn’t ideal but workable.
What volume of data you are discussing? How many physical nodes? Can you give a complete usage example of what you want to achieve?
In general, there’s a steep change in making things distributed properly, and distributed systems are often designed for big and complex situations, so they “can afford” being big and complex too.
