NAME         top

       vgscan — scan all disks for volume groups and rebuild caches

SYNOPSIS         top

       vgscan [--commandprofile ProfileName] [-d|--debug] [-h|-?|--help]
       [--ignorelockingfailure] [--mknodes] [--notifydbus] [-P|--partial]
       [--reportformat {basic|json}] [-v|--verbose]

DESCRIPTION         top

       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         top

       See lvm(8) for common options.

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

              Send a notification to D-Bus. The command will exit with an
              error if LVM is not built with support for D-Bus notification,
              or if the notify_dbus config setting is disabled.

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