Synology Music player: file not found

I was having problems with my Synology and the mobile DS Audio player application. Quite often, maybe every 10 or 15 minutes I would get "file not found" error.

Turns out that I had a load of orphaned ._ files likely from using iTunes to do album management.

Logging in by SSH, I ran the command

cd volume1
cd music
find . -name "._*" -exec rm -i '{}' \; -print

Usually this would ask if you want to delete any files found, but since the Synology file system couldn't find the files gave errors instead. I used the errors to work through deleting the offenders.

I found that OSX finder and even command line would not delete the files. If there was a folder with some lost files I copied off anythng I wanted to save and then used Filestation to delete, and that worked OK.

Then I used Audio Station to re-index the media, and then checked my play lists.
