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 ]
           [    --refresh ]
           [    --reportformat basic|json ]
           [ COMMON_OPTIONS ]
           [ VG|LV|Tag ... ]

       Common options for lvm:
           [ -d|--debug ]
           [ -h|--help ]
           [ -q|--quiet ]
           [ -t|--test ]
           [ -v|--verbose ]
           [ -y|--yes ]
           [    --commandprofile String ]
           [    --config String ]
           [    --driverloaded y|n ]
           [    --longhelp ]
           [    --profile String ]
           [    --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 settings.  The String arg
              uses the same format as lvm.conf, or may use section/field syntax.  See lvm.conf(5)
              for more information 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).

       --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.

       --longhelp
              Display long help text.

       --profile String
              An alias for --commandprofile or --metadataprofile, depending on the command.

       -q|--quiet ...
              Suppress output and log messages. Overrides --debug and --verbose.  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.  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 positional 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 content.

       Size[UNIT]
              Size  is  an  input  number  that accepts an optional unit.  Input units are always
              treated as base two values, regardless of capitalization, e.g.  'k'  and  'K'  both
              refer  to  1024.  The default input unit is specified by letter, followed by |UNIT.
              UNIT represents other possible input units: bBsSkKmMgGtTpPeE.  b|B is bytes, s|S is
              sectors  of 512 bytes, k|K is kilobytes, m|M is megabytes, g|G is gigabytes, t|T is
              terabytes, p|P is petabytes, e|E is exabytes.  (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.
