lvscan scans all known volume groups or all supported LVM block
devices in the system for defined Logical Volumes. The output
consists of one line for each Logical Volume indicating whether or
not it is active, a snapshot or origin, the size of the device and
its allocation policy. Use lvs(8) or lvdisplay(8) to obtain more-
comprehensive information about the Logical Volumes.
See lvm(8) for common options.
--all Include information in the output about internal Logical
Volumes that are components of normally-accessible Logical
Volumes, such as mirrors, but which are not independently
accessible (e.g. not mountable). For example, after creating
a mirror using lvcreate -m1 --mirrorlog disk, this option will
reveal three internal Logical Volumes, with suffixes mimage_0,
mimage_1, and mlog.
This option is now ignored. Instead, use lvs(8) or
lvdisplay(8) to obtain the device number.
Applicable only when lvmetad(8) is in use (see also
lvm.conf(5), global/use_lvmetad). This command issues a rescan
of physical volume labels and metadata areas of all PVs that
the logical volume uses. In particular, this can be used when
a RAID logical volume becomes degraded, to update information
about physical volume availability. This is only necessary if
the logical volume is not being monitored by dmeventd (see
lvchange(8), option --monitor).
