pvchange - Change attributes of physical volume(s)
pvchange option_args position_args
[ option_args ]
pvchange changes PV attributes in the VG.
For options listed in parentheses, any one is required, after which the others are optional.
Change properties of all PVs.
pvchange
Change properties of specified PVs.
pvchange
Common options for command:
Common options for lvm:
--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 settings. 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.
--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. 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.)
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:
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.)
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.
Disallow the allocation of physical extents on a PV (e.g. because
of disk errors, or because it will be removed after freeing it).
