Are there any other (de)merits about the following FS mounting methods？
- the DM method, just means
/dev/mapper/<VG>-<LV>, can handle its own multipath I/O.
- the non-DM methods, such as UUID/LABEL/LVM, cannot handle their own multipath I/O？
- UUID: the system randomly generated persistent logical ID, without its original low-level attributs
- LABEL: the user customarily defined persistent logical ID, without its original high-level attributs
- LVM: also means
/dev/mapper/<VG>-<LV>, it almost has no any (de)merit？
