Is LiteFS a direct replacement for multiple volumes

[tj1]

@stevenfitzpatrick

If I want my data to be in sync across both volumes (because my machines will switch during a deploy) I need to switch to LiteFS.

Yes.

@stevenfitzpatrick

My LiteFS setup can stay the same 2 machines and 2 volumes for the one region.

Probably best to have two regions, but yes.

@stevenfitzpatrick

What would be easiest way to allow the new machine + volume combo to be allowed to write automatically. Is this where the litefs proxy comes into play? Basically I am hoping for a simple setup like above I need to manage who can write and who can read this there will only be 1 active machine + volume at anytime if that makes sense?

Yes, this is where litefs proxy comes in. Wherever a write comes in, the proxy forwards to the active / primary litefs. See the documentation here:
