NAME
       vgscan - scan all disks for volume groups and rebuild caches

SYNOPSIS
       vgscan [-d|--debug] [-h|-?|--help] [--ignorelockingfailure] [--mknodes] [-P|--partial] [-v|--verbose]

DESCRIPTION
       vgscan  scans all SCSI, (E)IDE disks, multiple devices and a bunch of other disk devices in the system looking for LVM physical volumes and
       volume groups.  Define a filter in lvm.conf(5) to restrict the scan to avoid a CD ROM, for example.

       In LVM2, vgscans take place automatically; but you might still need to run one explicitly after changing hardware.

OPTIONS
       See lvm for common options.

       --mknodes
	      Also checks the LVM special files in /dev that are needed for active logical volumes and creates any missing ones and removes unused
	      ones.

NAME
pvscan - scan all disks for physical volumes SYNOPSIS
pvscan [-d|--debug] [-h|--help] [-v|--verbose] [--version] [--ignorelockingfailure] [-e|--exported] [-n|--novolumegroup] [-s|--short] [-u|--uuid] pvscan [-d|--debug] [-h|--help] --cache [--major major --minor minor | DevicePath ] ... DESCRIPTION
pvscan scans all supported LVM block devices in the system for physical volumes. OPTIONS
See lvm(8) for common options. -e, --exported Only show physical volumes belonging to exported volume groups. -n, --novolumegroup Only show physical volumes not belonging to any volume group. -s, --short Short listing format. -u, --uuid Show UUIDs (Uniform Unique Identifiers) in addition to device special names. --cache [ --major major --minor minor | DevicePath ] ... Scan one or more devices and instruct the lvmetad daemon to update its cached state accordingly. Called internally by udev rules. All devices listed explicitly are processed regardless of any device filters set in lvm.conf. SEE ALSO
