The lvdisplay command displays the characteristics and status of each logical volume specified by the LogicalVolumePath parameter. If you use the -v (verbose) option, the program displays physical volume (PV) distribution information, and map information about the physical extents that correspond to the logical extents of the logical volume(s).
If you enter the lvdisplay command without any flags, the program displays information about the following characteristics: The name of the logical volume The name of the volume group The access permission: read-only or read-write The state of the logical volume: available/stale, available/syncd, or unavailable
Available/stale indicates that the logical volume is available but contains physical extents that are not current. Available/syncd indicates that the logical volume is available and synchronized. Unavailable indicates that the logical volume is not available for use. The write verify state of the logical volume: on or off The number of physical extents allocated for each logical extent The sequential or parallel scheduling policy The number of logical extents currently in the logical volume The number of physical extents allocated to the logical volume The bad block relocation policy The current allocation state: strict or non-strict A strict allocation specifies that mirror copies for a logical extent are not allocated on the same physical volume. A non-strict allocation specifies that physical extents that belong to the same logical extent can be allocated on the same physical volume. If the allocation does not meet the criteria for strict, it is considered to be non-strict.
Distribution of logical volume: lists the distribution of the logical volume LogicalVolumePath within the volume group: The name of the physical volume to which the logical extents are allocated The number of logical extents that are allocated on the physical volume The number of physical extents that are allocated on the physical volume
Logical extents: displays the following information for each logical extent: The logical extent number The physical volume name that corresponds to the location of the first physical extent of the logical extent The first physical extent number allocated to the logical extent The status of the first physical extent: stale or current The physical volume name that corresponds to the location of the second physical extent (first copy) of the logical extent The second physical extent number allocated to the logical extent The status of the second physical extent: stale or current The physical volume name that corresponds to the location of the third physical extent (second copy) of the logical extent The third physical extent number allocated to the logical extent The status of the third physical extent: stale or current
