Параметры (Options)
--addtag Tag
Adds a tag to a PV, VG or LV. This option can be repeated
to add multiple tags at once. See lvm(8) for information
about tags.
-a|--all
Change all visible PVs.
-x|--allocatable y|n
Enable or disable allocation of physical extents on this
PV.
-A|--autobackup y|n
Specifies if metadata should be backed up automatically
after a change. Enabling this is strongly advised! See
vgcfgbackup(8) for more information.
--commandprofile String
The command profile to use for command configuration. See
lvm.conf(5) for more information about profiles.
--config String
Config settings for the command. These override
lvm.conf(5) settings. The String arg uses the same format
as lvm.conf(5), or may use section/field syntax. See
lvm.conf(5) for more information about config.
-d|--debug ...
Set debug level. Repeat from 1 to 6 times to increase the
detail of messages sent to the log file and/or syslog (if
configured).
--deltag Tag
Deletes a tag from a PV, VG or LV. This option can be
repeated to delete multiple tags at once. See lvm(8) for
information about tags.
--devices PV
Devices that the command can use. This option can be
repeated or accepts a comma separated list of devices.
This overrides the devices file.
--devicesfile String
A file listing devices that LVM should use. The file must
exist in /etc/lvm/devices/ and is managed with the
lvmdevices(8) command. This overrides the lvm.conf(5)
devices/devicesfile and devices/use_devicesfile settings.
--driverloaded y|n
If set to no, the command will not attempt to use device-
mapper. For testing and debugging.
-f|--force ...
Override various checks, confirmations and protections.
Use with extreme caution.
-h|--help
Display help text.
--lockopt String
Used to pass options for special cases to lvmlockd. See
lvmlockd(8) for more information.
--longhelp
Display long help text.
--metadataignore y|n
Specifies the metadataignore property of a PV. If yes,
metadata areas on the PV are ignored, and lvm will not
store metadata in the metadata areas of the PV. If no,
lvm will store metadata on the PV.
--nolocking
Disable locking.
--profile String
An alias for --commandprofile or --metadataprofile,
depending on the command.
-q|--quiet ...
Suppress output and log messages. Overrides --debug and
--verbose. Repeat once to also suppress any prompts with
answer 'no'.
--reportformat basic|json
Overrides current output format for reports which is
defined globally by the report/output_format setting in
lvm.conf(5). basic is the original format with columns
and rows. If there is more than one report per command,
each report is prefixed with the report name for
identification. json produces report output in JSON
format. See lvmreport(7) for more information.
-S|--select String
Select objects for processing and reporting based on
specified criteria. The criteria syntax is described by
--select help and lvmreport(7). For reporting commands,
one row is displayed for each object matching the
criteria. See --options help for selectable object
fields. Rows can be displayed with an additional
"selected" field (-o selected) showing 1 if the row
matches the selection and 0 otherwise. For non-reporting
commands which process LVM entities, the selection is used
to choose items to process.
-t|--test
Run in test mode. Commands will not update metadata. This
is implemented by disabling all metadata writing but
nevertheless returning success to the calling function.
This may lead to unusual error messages in multi-stage
operations if a tool relies on reading back metadata it
believes has changed but hasn't.
-u|--uuid
Generate new random UUID for specified PVs.
-v|--verbose ...
Set verbose level. Repeat from 1 to 4 times to increase
the detail of messages sent to stdout and stderr.
--version
Display version information.
-y|--yes
Do not prompt for confirmation interactively but always
assume the answer yes. Use with extreme caution. (For
automatic no, see -qq.)
Переменные (Variables)
PV Physical Volume name, a device path under /dev. For
commands managing physical extents, a PV positional arg
generally accepts a suffix indicating a range (or multiple
ranges) of physical extents (PEs). When the first PE is
omitted, it defaults to the start of the device, and when
the last PE is omitted it defaults to end. Start and end
range (inclusive): PV[:PE-PE]... Start and length range
(counting from 0): PV[:PE+PE]...
Select Select indicates that a required positional parameter can
be omitted if the --select option is used. No arg appears
in this position.
String See the option description for information about the
string content.
Size[UNIT]
Size is an input number that accepts an optional unit.
Input units are always treated as base two values,
regardless of capitalization, e.g. 'k' and 'K' both refer
to 1024. The default input unit is specified by letter,
followed by |UNIT. UNIT represents other possible input
units: b|B is bytes, s|S is sectors of 512 bytes, k|K is
KiB, m|M is MiB, g|G is GiB, t|T is TiB, p|P is PiB, e|E
is EiB. (This should not be confused with the output
control --units, where capital letters mean multiple of
1000.)
Переменные окружения (Environment variables)
See lvm(8) for information about environment variables used by
lvm. For example, LVM_VG_NAME can generally be substituted for a
required VG parameter.
Примеры (Examples)
Disallow the allocation of physical extents on a PV (e.g. because
of disk errors, or because it will be removed after freeing it).
