OPTIONS

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

VARIABLES

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

ENVIRONMENT VARIABLES

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