vgmknodes - Create the special files for volume group devices in /dev
vgmknodes
[ option_args ]
[ position_args ]
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.

[ 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 ]
--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.)
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.)
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.
