Solutions

1. Set the state persist directory configuration (sls/rumen state dir) to enable persistence, or ignore the warning to run without persistence.

When it happens

Trigger: StatePool is asked to persist state but no persist directory is configured, so persistence is disabled.

Common situations: See trigger scenarios.
