| This is LVM2, the rewrite of The Linux Logical Volume Manager. |
| LVM supports enterprise level volume management of disk and |
| disk subsystems by grouping arbitrary disks into volume |
| groups. The total capacity of volume groups can be allocated |
| to logical volumes, which are accessed as regular block |
| devices. |
| |
| The Linux Kernel Device Mapper is the LVM |
| (Linux Logical Volume Management) Team's implementation of a |
| minimalistic kernel-space driver that handles volume |
| management, while keeping knowledge of the underlying device |
| layout in user-space. This makes it useful for not only LVM, |
| but EVMS, software raid, and other drivers that create |
| "virtual" block devices. |

| Install lvmetad |
| |
| The lvmetad daemon caches LVM metadata so that LVM commands |
| can read metadata from the cache rather than scanning disks. |
| This can be an advantage because scanning disks is time |
| consuming and may interfere with the normal work of the |
| system. lvmetad can be a disadvantage when disk event |
| notifications from the system are unreliable. |
