Music Assistant fixes an upgrade failure that could delete the entire music library when storage ran out. Moving audio-analysis data already stopped safely on a full disk, but a later cache cleanup failed too and triggered a recovery path that discarded the library database.
The cleanup failure now produces a warning without resetting the library. If the old analysis tables remain, each subsequent start checks for enough space and retries the move; without room, startup continues and reports the space needed. This prevents the loss rather than recovering a library already deleted.
