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.
