Multi-Instance

HaruHostGSM allows you to reuse the same Ark Survival Ascended installation for multiple servers. This saves disk space and means you only update a single install instead of every server, which helps on slower internet connections.

How it works

• Multiple servers can point to the same install directory while keeping their own configs, saves, and ports.
• HaruHostGSM coordinates startup so additional instances wait for the first instance to finish loading. It can take a few minutes before all instances come online.

Update procedure (shared install)

Only one instance should run the game update to avoid conflicting writes.

1. Shut down all servers that share the same install directory. Use Bulk Actions for speed.
2. Run Update on exactly one of those servers.
3. After the update completes, all servers using that install directory are now updated. Start the others as needed.

Known limitations

• Update conflicts: if more than one multi‑instance tries to update simultaneously, the process will collide and fail. Always update a single instance while the others are stopped.
• Startup delay: additional instances wait for the first server to come online. Expect a short delay (up to a few minutes) before every instance reports Online.

If you run into issues, confirm all instances are stopped before updating and start them again in sequence after the first one finishes.
