AI Summary: This GitHub issue reports a file descriptor leak in the `writeMetaFile` function within `tsdb/block.go`. An `os.Create` call opens a file, but a specific early return path `return 0, err` exits without closing the file descriptor, unlike other error handling branches that correctly use `errors.Join(err, f.Close())`. This leads to a leaked file descriptor if an error triggers this particular return path.
