The SSD on turing3 (/mnt/ssd) is shared by Postgres, Plex's SQLite DB and the media library. When it fills, Postgres crashes (cannot write postmaster.pid) and Plex's library DB corrupts. Add a CronJob that checks df via the plex-data mount every 15m and warns Telegram at >=90% used (3h cooldown). Bot token/chatId live in the out-of-band `telegram-disk-alert` Secret, not in git.
