   lvmdiskscan    ( 8 )

список устройств, которые могут использоваться как физические тома (List devices that may be used as physical volumes)

Имя (Name)

lvmdiskscan — List devices that may be used as physical volumes


Синопсис (Synopsis)

lvmdiskscan [ option_args ]


Описание (Description)

lvmdiskscan scans all SCSI, (E)IDE disks, multiple devices and a bunch of other block devices in the system looking for LVM PVs. The size reported is the real device size. Define a filter in lvm.conf(5) to restrict the scan to avoid a CD ROM, for example.

This command is deprecated, use pvs instead.


Использование (Usage)

lvmdiskscan [ -l|--lvmpartition ] [ --readonly ] [ COMMON_OPTIONS ]

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)

--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).

--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.

-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.

-l|--lvmpartition Only report PVs.

--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'.

--readonly Run the command in a special read-only mode which will read on-disk metadata without needing to take any locks. This can be used to peek inside metadata used by a virtual machine image while the virtual machine is running. No attempt will be made to communicate with the device-mapper kernel driver, so this option is unable to report whether or not LVs are actually in use.

-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.

-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)

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.
