I do not run raid and tend to remove a drive now and then. my system auto mounts the drives like
VOL1 +VOL2 +VOL3 … VOL20
they are merged into a large mediavolume that sonarr uses.
the problem is when I remove a drive and if sonar notices it it will start trying to find all the episodes that happen to be on that drive and start them processing creating duplicates on the other drives. It’s not fatal as I use mergerfs +btrfs filesystem that handles dups sort of.
What I am wondering if the scan routine could have a button that appears if it notices files that used to exist that disappeared offering to pause the processing for a week or month. Even a manual way to halt all processing. so at least I can still edit show lists and such. Radar also needs a way to halt its processing.
