OPTIONS

39       --commandprofile String
40              The command profile to use for command configuration.  See
41              lvm.conf(5) for more information about profiles.
42
43       --config String
44              Config settings for the command. These override lvm.conf set‐
45              tings.  The String arg uses the same format as lvm.conf, or may
46              use section/field syntax.  See lvm.conf(5) for more information
47              about config.
48
49       -d|--debug ...
50              Set debug level. Repeat from 1 to 6 times to increase the detail
51              of messages sent to the log file and/or syslog (if configured).
52
53       --driverloaded y|n
54              If set to no, the command will not attempt to use device-mapper.
55              For testing and debugging.
56
57       -h|--help
58              Display help text.
59
60       --lockopt String
61              Used to pass options for special cases to lvmlockd.  See lvm‐
62              lockd(8) for more information.
63
64       --longhelp
65              Display long help text.
66
67       --nolocking
68              Disable locking.
69
70       --profile String
71              An alias for --commandprofile or --metadataprofile, depending on
72              the command.
73
74       -q|--quiet ...
75              Suppress output and log messages. Overrides --debug and --ver‐
76              bose.  Repeat once to also suppress any prompts with answer
77              'no'.
78
79       --reportformat basic|json
80              Overrides current output format for reports which is defined
81              globally by the report/output_format setting in lvm.conf.  basic
82              is the original format with columns and rows.  If there is more
83              than one report per command, each report is prefixed with the
84              report name for identification. json produces report output in
85              JSON format. See lvmreport(7) for more information.
86
87       -t|--test
88              Run in test mode. Commands will not update metadata.  This is
89              implemented by disabling all metadata writing but nevertheless
90              returning success to the calling function. This may lead to
91              unusual error messages in multi-stage operations if a tool
92              relies on reading back metadata it believes has changed but
93              hasn't.
94
95       -v|--verbose ...
96              Set verbose level. Repeat from 1 to 4 times to increase the
97              detail of messages sent to stdout and stderr.
98
99       --version
100              Display version information.
101
102       -y|--yes
103              Do not prompt for confirmation interactively but always assume
104              the answer yes. Use with extreme caution.  (For automatic no,
105              see -qq.)
106

VARIABLES

108       VG
109              Volume Group name.  See lvm(8) for valid names.
110
111       Tag
112              Tag name.  See lvm(8) for information about tag names and  using
113              tags in place of a VG, LV or PV.
114
115       String
116              See the option description for information about the string con‐
117              tent.
118
119       Size[UNIT]
120              Size is an input number that accepts an  optional  unit.   Input
121              units are always treated as base two values, regardless of capi‐
122              talization, e.g. 'k' and 'K' both refer to  1024.   The  default
123              input unit is specified by letter, followed by |UNIT.  UNIT rep‐
124              resents other possible input units:  bBsSkKmMgGtTpPeE.   b|B  is
125              bytes,  s|S  is  sectors  of 512 bytes, k|K is kilobytes, m|M is
126              megabytes, g|G is gigabytes, t|T is terabytes, p|P is petabytes,
127              e|E  is  exabytes.  (This should not be confused with the output
128              control --units, where capital letters mean multiple of 1000.)

ENVIRONMENT VARIABLES

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