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 set-
tings. The String arg uses the same format as lvm.conf, 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.
--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.
--ignoreskippedcluster
Use to avoid exiting with an non-zero status code if the command
is run without clustered locking and clustered VGs are skipped.
--lockopt String
Used to pass options for special cases to lvmlockd. See lvm-
lockd(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.
--profile String
An alias for --commandprofile or --metadataprofile, depending on
the command.
-q|--quiet ...
Suppress output and log messages. Overrides --debug and --ver-
bose. 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. 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 addi-
tional "selected" field (-o selected) showing 1 if the row
matches the selection and 0 otherwise. For non-reporting com-
mands 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.)
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 con-
tent.
Size[UNIT]
Size is an input number that accepts an optional unit. Input
units are always treated as base two values, regardless of capi-
talization, e.g. 'k' and 'K' both refer to 1024. The default
input unit is specified by letter, followed by |UNIT. UNIT rep-
resents other possible input units: bBsSkKmMgGtTpPeE. b|B is
bytes, s|S is sectors of 512 bytes, k|K is kilobytes, m|M is
megabytes, g|G is gigabytes, t|T is terabytes, p|P is petabytes,
e|E is exabytes. (This should not be confused with the output
control --units, where capital letters mean multiple of 1000.)
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.
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).
