44 --commandprofile String
45 The command profile to use for command configuration. See
46 lvm.conf(5) for more information about profiles.
47 --config String
49 Config settings for the command. These override lvm.conf(5) set‐
50 tings. The String arg uses the same format as lvm.conf(5), or
51 may use section/field syntax. See lvm.conf(5) for more informa‐
52 tion about config.
53 -d|--debug ...
55 Set debug level. Repeat from 1 to 6 times to increase the detail
56 of messages sent to the log file and/or syslog (if configured).
57 --devices PV
59 Restricts the devices that are visible and accessible to the
60 command. Devices not listed will appear to be missing. This op‐
61 tion can be repeated, or accepts a comma separated list of de‐
62 vices. This overrides the devices file.
63 --devicesfile String
65 A file listing devices that LVM should use. The file must exist
66 in /etc/lvm/devices/ and is managed with the lvmdevices(8) com‐
67 mand. This overrides the lvm.conf(5) devices/devicesfile and
68 devices/use_devicesfile settings.
69 --driverloaded y|n
71 If set to no, the command will not attempt to use device-mapper.
72 For testing and debugging.
73 -h|--help
75 Display help text.
76 --ignorelockingfailure
78 Allows a command to continue with read-only metadata operations
79 after locking failures.
80 --journal String
82 Record information in the systemd journal. This information is
83 in addition to information enabled by the lvm.conf log/journal
84 setting. command: record information about the command. out‐
85 put: record the default command output. debug: record full com‐
86 mand debugging.
87 --lockopt String
89 Used to pass options for special cases to lvmlockd. See lvm‐
90 lockd(8) for more information.
91 --longhelp
93 Display long help text.
94 --mknodes
96 Also checks the LVM special files in /dev that are needed for
97 active LVs and creates any missing ones and removes unused ones.
98 --nohints
100 Do not use the hints file to locate devices for PVs. A command
101 may read more devices to find PVs when hints are not used. The
102 command will still perform standard hint file invalidation where
103 appropriate.
104 --nolocking
106 Disable locking. Use with caution, concurrent commands may pro‐
107 duce incorrect results.
108 --notifydbus
110 Send a notification to D-Bus. The command will exit with an er‐
111 ror if LVM is not built with support for D-Bus notification, or
112 if the notify_dbus config setting is disabled.
113 --profile String
115 An alias for --commandprofile or --metadataprofile, depending on
116 the command.
117 -q|--quiet ...
119 Suppress output and log messages. Overrides --debug and --ver‐
120 bose. Repeat once to also suppress any prompts with answer
121 'no'.
122 --reportformat basic|json|json_std
124 Overrides current output format for reports which is defined
125 globally by the report/output_format setting in lvm.conf(5).
126 basic is the original format with columns and rows. If there is
127 more than one report per command, each report is prefixed with
128 the report name for identification. json produces report output
129 in JSON format. json_std produces report output in JSON format
130 which is more compliant with JSON standard. See lvmreport(7)
131 for more information.
132 -t|--test
134 Run in test mode. Commands will not update metadata. This is
135 implemented by disabling all metadata writing but nevertheless
136 returning success to the calling function. This may lead to un‐
137 usual error messages in multi-stage operations if a tool relies
138 on reading back metadata it believes has changed but hasn't.
139 -v|--verbose ...
141 Set verbose level. Repeat from 1 to 4 times to increase the de‐
142 tail of messages sent to stdout and stderr.
143 --version
145 Display version information.
146 -y|--yes
148 Do not prompt for confirmation interactively but always assume
149 the answer yes. Use with extreme caution. (For automatic no,
150 see -qq.)
151
153 String See the option description for information about the string con‐
154 tent.
155 Size[UNIT]
157 Size is an input number that accepts an optional unit. Input
158 units are always treated as base two values, regardless of capi‐
159 talization, e.g. 'k' and 'K' both refer to 1024. The default
160 input unit is specified by letter, followed by |UNIT. UNIT rep‐
161 resents other possible input units: b|B is bytes, s|S is sectors
162 of 512 bytes, k|K is KiB, m|M is MiB, g|G is GiB, t|T is TiB,
163 p|P is PiB, e|E is EiB. (This should not be confused with the
164 output control --units, where capital letters mean multiple of
165 1000.)
166
168 See lvm(8) for information about environment variables used by lvm.
169 For example, LVM_VG_NAME can generally be substituted for a required VG
170 parameter.
