NAME
lvscan --- scan (all disks) for Logical Volumes
SYNOPSIS
lvscan [-a|--all] [-b|--blockdevice] [--commandprofile ProfileName] [-d|--debug] [-h|--help] [--ignorelockingfailure] [-P|--partial] [--reportformat {basic|json}] [-v|--verbose]
DESCRIPTION
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.
OPTIONS
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. -b, --blockdevice This option is now ignored. Instead, use lvs(8) or lvdisplay(8) to obtain the device number. --cache LogicalVolume 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).
