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(8) 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.

       --cache
	      Scan devices for LVM physical volumes and volume groups and instruct the lvmetad daemon to update its cached state accordingly.

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.
