Oh man…I feel terrible. After going through my entire configuration (Sonarr, Deluge, SABnzbd, UnRAID etc), I noticed my media share (where /tv is mapped for the tv shows) was somehow set to only use my cache drive instead of the array. I have no idea how this happened but it could coincide with a recent system update to UnRAID. In any case, once I corrected this, everything was back to normal! I’m really sorry for wasting your time troubleshooting this one. I wonder if it’s possible to make the error more descript as a result?
Anyway, I think I may need to figure out this Torrent Blackhole client instead of Deluge as a client in Sonarr. What I figured out about the torrent not being removed in Deluge seems to be related to the global torrent preferences not being fully applied when Sonarr sends the torrent to Deluge. When I manually import a torrent into Deluge, the settings are applied and the torrent is removed once seeding is complete.
Preference settings in Sonarr:
Options shown for specific torrent imported by Sonarr:
Interestingly enough, the file is moved to /downloads even though it’s not checked but it remains in Deluge in the paused state signifying seed ratio has been met. When I import a torrent manually, both of these options are checked.
