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 ]
           [    --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 ]
           [    --lockopt String ]
           [    --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 set-
              tings.  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.
       --lockopt String
              Used to pass options for special cases to lvmlockd.  See lvm-
              lockd(8) for more information.
       --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 --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.  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: 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.
