VGMKNODES(8)                System Manager's Manual               VGMKNODES(8)
NAME
       vgmknodes -- Create the special files for volume group devices in /dev
SYNOPSIS
       vgmknodes
           [ option_args ]
           [ position_args ]
DESCRIPTION
       vgmknodes  checks  the  LVM  device  nodes  in /dev that are needed for
       active LVs and creates any that are missing and removes unused ones.
       This command should not usually be needed if all the system  components
       are interoperating correctly.
USAGE
       vgmknodes
           [    --ignorelockingfailure ]

           [    --version ]
OPTIONS
       --commandprofile String
              The  command  profile  to  use  for  command configuration.  See
              lvm.conf(5) for more information about profiles.
       --config String
              Config settings for the command. These override lvm.conf(5) set-
              tings.   The  String arg uses the same format as lvm.conf(5), or
              may use section/field syntax.  See lvm.conf(5) for more informa-
              tion about config.
       -d|--debug ...
              Set debug level. Repeat from 1 to 6 times to increase the detail
              of messages sent to the log file and/or syslog (if configured).
       --devices PV
              Restricts the devices that are visible  and  accessible  to  the
              command.   Devices  not  listed  will appear to be missing. This
              option can be repeated, or accepts a  comma  separated  list  of
              devices. This overrides the devices file.
       --devicesfile String
              A file listing devices that LVM should use.  The file must exist
              in /etc/lvm/devices/ and is managed with the lvmdevices(8)  com-
              mand.   This  overrides  the lvm.conf(5) devices/devicesfile and
              devices/use_devicesfile settings.
       --driverloaded y|n
              If set to no, the command will not attempt to use device-mapper.
              For testing and debugging.
       -h|--help
              Display help text.
       --ignorelockingfailure
              Allows  a command to continue with read-only metadata operations
              after locking failures.
       --journal String
              Record information in the systemd journal.  This information  is
              in  addition  to information enabled by the lvm.conf log/journal
              setting.  command: record information about the  command.   out-
              put: record the default command output.  debug: record full com-
              mand debugging.
       --lockopt String
              Used to pass options for special cases to  lvmlockd.   See  lvm-
              lockd(8) for more information.
       --longhelp
              Display long help text.
       --nohints
              Do  not  use the hints file to locate devices for PVs. A command
              may read more devices to find PVs when hints are not  used.  The
              command will still perform standard hint file invalidation where
              appropriate.
       --nolocking
              Disable locking.
       --profile String
              An alias for --commandprofile or --metadataprofile, depending on
              the command.
       -q|--quiet ...
              Suppress  output  and log messages. Overrides --debug and --ver-
              bose.  Repeat once to also  suppress  any  prompts  with  answer
              'no'.
       --refresh
              If the LV is active, reload its metadata.  This is not necessary
              in normal operation, but may be useful  if  something  has  gone
              wrong, or if some form of manual LV sharing is being used.
       --reportformat basic|json
              Overrides  current  output  format  for reports which is defined
              globally by the  report/output_format  setting  in  lvm.conf(5).
              basic is the original format with columns and rows.  If there is
              more than one report per command, each report is  prefixed  with
              the  report name for identification. json produces report output
              in JSON format. See lvmreport(7) for more information.
       -t|--test
              Run in test mode. Commands will not update  metadata.   This  is
              implemented  by  disabling all metadata writing but nevertheless
              returning success to the calling  function.  This  may  lead  to
              unusual  error  messages  in  multi-stage  operations  if a tool
              relies on reading back metadata  it  believes  has  changed  but
              hasn't.
       -v|--verbose ...
              Set  verbose  level.  Repeat  from  1 to 4 times to increase the
              detail of messages sent to stdout and stderr.
       --version
              Display version information.
       -y|--yes
              Do not prompt for confirmation interactively but  always  assume
              the  answer  yes.  Use with extreme caution.  (For automatic no,
              see -qq.)
VARIABLES
       VG     Volume Group name.  See lvm(8) for valid names.
       LV     Logical Volume name.  See lvm(8) for valid names.  An  LV  posi-
              tional  arg  generally  includes  the  VG name and LV name, e.g.
              VG/LV.
       Tag    Tag name.  See lvm(8) for information about tag names and  using
              tags in place of a VG, LV or PV.
       String See the option description for information about the string con-
              tent.
       Size[UNIT]
              Size is an input number that accepts an  optional  unit.   Input
              units are always treated as base two values, regardless of capi-
              talization, e.g. 'k' and 'K' both refer to  1024.   The  default
              input unit is specified by letter, followed by |UNIT.  UNIT rep-
              resents other possible input units: b|B is bytes, s|S is sectors
              of  512  bytes,  k|K is KiB, m|M is MiB, g|G is GiB, t|T is TiB,
              p|P is PiB, e|E is EiB.  (This should not be confused  with  the
              output  control  --units, where capital letters mean multiple of
              1000.)
ENVIRONMENT VARIABLES
       See lvm(8) for information about environment  variables  used  by  lvm.
       For example, LVM_VG_NAME can generally be substituted for a required VG
       parameter.
