Использование (Usage)

Change properties of all PVs.

pvchange -a|--all ( -x|--allocatable y|n -u|--uuid --addtag Tag --deltag Tag --metadataignore y|n ) [ COMMON_OPTIONS ]

Change properties of specified PVs.

pvchange ( -x|--allocatable y|n -u|--uuid --addtag Tag --deltag Tag --metadataignore y|n ) PV|Select ... [ -S|--select String ] [ COMMON_OPTIONS ]

Common options for command: [ -A|--autobackup y|n ] [ -f|--force ] [ -u|--uuid ] [ --reportformat basic|json ]

Common options for lvm: [ -d|--debug ] [ -h|--help ] [ -q|--quiet ] [ -t|--test ] [ -v|--verbose ] [ -y|--yes ] [ --commandprofile String ] [ --config String ] [ --devices PV ] [ --devicesfile String ] [ --driverloaded y|n ] [ --lockopt String ] [ --longhelp ] [ --nolocking ] [ --profile String ] [ --version ]


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).
       pvchange -x n /dev/sdk1
