SYNOPSIS

9       vgmknodes
10           [ option_args ]
11           [ position_args ]

DESCRIPTION

14       vgmknodes  checks  the  LVM  device  nodes  in /dev that are needed for
15       active LVs and creates any that are missing and removes unused ones.
16
17       This command should not usually be needed if all the system  components
18       are interoperating correctly.

OPTIONS

45       --commandprofile String
46              The command profile to use for command configuration.  See
47              lvm.conf(5) for more information about profiles.
48
49       --config String
50              Config settings for the command. These override lvm.conf set‐
51              tings.  The String arg uses the same format as lvm.conf, or may
52              use section/field syntax.  See lvm.conf(5) for more information
53              about config.
54
55       -d|--debug ...
56              Set debug level. Repeat from 1 to 6 times to increase the detail
57              of messages sent to the log file and/or syslog (if configured).
58
59       --driverloaded y|n
60              If set to no, the command will not attempt to use device-mapper.
61              For testing and debugging.
62
63       -h|--help
64              Display help text.
65
66       --ignorelockingfailure
67              Allows a command to continue with read-only metadata operations
68              after locking failures.
69
70       --lockopt String
71              Used to pass options for special cases to lvmlockd.  See lvm‐
72              lockd(8) for more information.
73
74       --longhelp
75              Display long help text.
76
77       --nolocking
78              Disable locking.
79
80       --profile String
81              An alias for --commandprofile or --metadataprofile, depending on
82              the command.
83
84       -q|--quiet ...
85              Suppress output and log messages. Overrides --debug and --ver‐
86              bose.  Repeat once to also suppress any prompts with answer
87              'no'.
88
89       --refresh
90              If the LV is active, reload its metadata.  This is not necessary
91              in normal operation, but may be useful if something has gone
92              wrong, or if some form of manual LV sharing is being used.
93
94       --reportformat basic|json
95              Overrides current output format for reports which is defined
96              globally by the report/output_format setting in lvm.conf.  basic
97              is the original format with columns and rows.  If there is more
98              than one report per command, each report is prefixed with the
99              report name for identification. json produces report output in
100              JSON format. See lvmreport(7) for more information.
101
102       -t|--test
103              Run in test mode. Commands will not update metadata.  This is
104              implemented by disabling all metadata writing but nevertheless
105              returning success to the calling function. This may lead to
106              unusual error messages in multi-stage operations if a tool
107              relies on reading back metadata it believes has changed but
108              hasn't.
109
110       -v|--verbose ...
111              Set verbose level. Repeat from 1 to 4 times to increase the
112              detail of messages sent to stdout and stderr.
113
114       --version
115              Display version information.
116
117       -y|--yes
118              Do not prompt for confirmation interactively but always assume
119              the answer yes. Use with extreme caution.  (For automatic no,
120              see -qq.)

VARIABLES

123       VG
124              Volume Group name.  See lvm(8) for valid names.
125
126       LV
127              Logical  Volume  name.  See lvm(8) for valid names.  An LV posi‐
128              tional arg generally includes the VG  name  and  LV  name,  e.g.
129              VG/LV.
130
131       Tag
132              Tag  name.  See lvm(8) for information about tag names and using
133              tags in place of a VG, LV or PV.
134
135       String
136              See the option description for information about the string con‐
137              tent.
138
139       Size[UNIT]
140              Size  is  an  input number that accepts an optional unit.  Input
141              units are always treated as base two values, regardless of capi‐
142              talization,  e.g.  'k'  and 'K' both refer to 1024.  The default
143              input unit is specified by letter, followed by |UNIT.  UNIT rep‐
144              resents  other  possible  input units: bBsSkKmMgGtTpPeE.  b|B is
145              bytes, s|S is sectors of 512 bytes, k|K  is  kilobytes,  m|M  is
146              megabytes, g|G is gigabytes, t|T is terabytes, p|P is petabytes,
147              e|E is exabytes.  (This should not be confused with  the  output
148              control --units, where capital letters mean multiple of 1000.)

ENVIRONMENT VARIABLES

151       See  lvm(8)  for  information  about environment variables used by lvm.
152       For example, LVM_VG_NAME can generally be substituted for a required VG
153       parameter.
