46
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 un‐
100 usual error messages in multi-stage operations if a tool relies
101 on reading back metadata it believes has changed but hasn't.
102
103 --updatemetadata
104 Update VG metadata to correct problems. If VG metadata was up‐
105 dated while a PV was missing, and the PV reappears with an old
106 version of metadata, then this option (or any other command that
107 writes metadata) will update the metadata on the previously
108 missing PV. If a PV was removed from a VG while it was missing,
109 and the PV reappears, using this option will clear the outdated
110 metadata from the previously missing PV. If metadata text is
111 damaged on one PV, using this option will replace the damaged
112 metadata text. For more severe damage, e.g. with headers, see
113 pvck(8).
114
115 -v|--verbose ...
116 Set verbose level. Repeat from 1 to 4 times to increase the de‐
117 tail of messages sent to stdout and stderr.
118
119 --version
120 Display version information.
121
122 -y|--yes
123 Do not prompt for confirmation interactively but always assume
124 the answer yes. Use with extreme caution. (For automatic no,
125 see -qq.)
126
128 VG
129 Volume Group name. See lvm(8) for valid names.
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 KiB, m|M is MiB, g|G
146 is GiB, t|T is TiB, p|P is PiB, e|E is EiB. (This should not be
147 confused with the output control --units, where capital letters
148 mean multiple of 1000.)
149
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.
