Notes / Gotchas

• Radarr root folder must be set to the path inside the container that maps to /mnt/Multimedia/Movies on the host.
• Hardlinking between /downloads and /media requires both paths to be on the same filesystem. The current setup has downloads on Ceph OSD and the final library on NFS — hardlinking is not possible across these. Radarr performs a copy+delete instead. This is slower but correct.
• Quality profiles are managed via Profilarr — avoid manual edits in Radarr UI.
