welcome to the forum,
sorry, not sure what that means?
you are trying to run two rclone commands at the same time or what?
as requested post a debug output using -vv, not -v
or
better yet post the output of --log-level=DEBUG --log-file=/path/to/rclone.log
note: delete the log before running rclone each time.
check out my howto guide about rclone + smb
side issue: not sure FLAClocal is required.
/Volumes/Data/FLAC should be the same as FLAClocal:/Volumes/Data/FLAC
