I encountered kind of a nasty bug the past couple of days which finally got nailed down to this: cache|user0|Logs|prefer|1759507742|938187962777|129|31|1|41061|./plugins/ca.mover.tuning/reset.php [3:53 PM] Mover_action_2025-10-06T154614.list:cache|Logs|prefer|1700089733|4395|3217845398|938187962777|1|5081|move unattended to primary|./plugins/dynamix|/mnt/cache|javascript/ace/mode-robot.js [3:54 PM] Debug_Mover_tuning_2025-10-06T154614.log:15:46:37.050 Current file: ./plugins/ca.mover.tuning/Mover.tuning.page, Current folder: ./plugins/ca.mover.tuning, Previous folder: /mnt/disk2/appdata/old_appdata/Jellyfin/metadata/People/A$AP Rocky, Previous count: 0 It found an automatically created folder for some artist named "A$AP Rocky" on the Array and evaluated the $ as the root folder for the webUI, and kept moving the entire contents of /usr/local/emhttp to the cache pool, effectively completely breaking unraid's web UI until reboot and trashing up the cache drives.
