I had a bit of a hiccup with my HDDs/Raid and lost a data drive. It was using unraid, so i only lost the data stored on that one drive, and it was about 0.6TB/14TB of the entire media collection (so maybe 5% of the media was lost and i dont really know which 5%).
Can someone please tell me how to tell Sonarr to recheck all its files to make sure it figures out which files i lost and re-download them?
You’ll need to refresh the series in Sonarr so it knows about the loss. That requires the series folder to exist and you’d want Ignore Deleted Episodes off otherwise they will be treated as deleted intentionally and ignored.
Enable Create Empty Series Folders and refresh the series from the main page, then you can use Wanted: Missing to search for selected or all missing episodes.
Im assuming you mean the “Update Library” button? I cant seem to find any reference to “refresh” anywhere, maybe im looking at the wrong place.
