10-1-2025 - Truenas OS went down during S.M.A.R.T. tests, reinstalled and configured again.

1. Installed new boot SSD
2. Set up users, samba, snapshots, backups, etc.
3. Went through a full tuning pass:
   • Got Redis working by pulling the right password from nextcloud-redis-creds.
   • Fixed persistence and eviction policies by setting env vars (REDIS_APPENDONLY, REDIS_MAXMEMORY, etc.) after discovering extra flags in args were breaking the Bitnami entrypoint.
   • Once Redis confirmed 8GB allkeys-lru with AOF enabled, I pivoted to Postgres.
   • found performance limited by a -c shared_buffers override injected at container startup, which ignored both postgresql.conf and ALTER SYSTEM.
   • Worked around this by testing direct SQL changes, editing configs, restarting the deployment, and finally confirming the cluster was still using command-line sources.

Results: Redis is tuned and persistent across rollouts, Postgres is partially tuned but still needs the command-line overrides stripped from the deployment spec to honor the larger memory settings.
