xenial (8) vgscan.8.gz

NAME

       vgscan — scan all disks for volume groups and rebuild caches

SYNOPSIS

       vgscan  [--commandprofile  ProfileName]  [-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.
