7

SYNOPSIS

9       vgmknodes
10           [ option_args ]
11           [ position_args ]

DESCRIPTION

14       vgmknodes  checks  the LVM device nodes in /dev that are needed for ac‐
15       tive 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 un‐
106              usual error messages in multi-stage operations if a tool relies
107              on reading back metadata it believes has changed but hasn't.
108
109       -v|--verbose ...
110              Set verbose level. Repeat from 1 to 4 times to increase the de‐
111              tail of messages sent to stdout and stderr.
112
113       --version
114              Display version information.
115
116       -y|--yes
117              Do not prompt for confirmation interactively but always assume
118              the answer yes. Use with extreme caution.  (For automatic no,
119              see -qq.)

VARIABLES

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

ENVIRONMENT VARIABLES

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