VGMKNODES(8)VGMKNODES(8)NAMEvgmknodes - Create the special files for volume group devices in /dev
SYNOPSISvgmknodes
[ option_args ]
[ position_args ]
DESCRIPTIONvgmknodes 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.
USAGEvgmknodes
[ --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 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.
--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.
