In brief

  • Ollama’s Linux guide describes running the server under a dedicated service account.
  • Confirm which account owns the model directory and verify that the storage mount is present before the service starts.

What to check

Ollama’s Linux guide describes running the server under a dedicated service account. Put machine-specific environment settings in a systemd drop-in and restart the service after applying them. Shell variables from your login session do not automatically become the service’s configuration. Check service status and test a request against loopback after reboot.

Put it to work

Confirm which account owns the model directory and verify that the storage mount is present before the service starts. Treat the unit, drop-ins and model inventory as deployment records. Before upgrading, capture the installed version and run the same short acceptance prompt afterward. A reproducible startup procedure makes it easier to distinguish a service failure from a model or GPU problem.

Practical workflow · Chain Perspective

Check the service after a cold reboot

Verify the service status, inspect the journal for startup errors, and then request the local model list. Seeing a running process is only the first check. Verify that the expected models appear and run a short local prompt. If the model list is empty after changing storage, inspect the service environment and mount permissions before downloading another copy.

Record a baseline you can restore

Keep the systemd drop-in and the expected runtime and model versions together. Record the mount dependency if weights live on a separate disk. A rollback test should restore a known-good configuration and answer the same short prompt with the expected placement. Keep shell tests and service tests distinct. A successful command as your login user can hide a permission issue that affects the dedicated service account.
