Имя (Name)
lvscan — List all logical volumes in all volume groups
Синопсис (Synopsis)
lvscan
[ option_args ]
Описание (Description)
lvscan scans all VGs or all supported LVM block devices in the
system for LVs. The output consists of one line for each LV
indicating whether or not it is active, a snapshot or origin, the
size of the device and its allocation policy. Use lvs(8) or
lvdisplay(8) to obtain more comprehensive information about LVs.

Параметры (Options)
-a
|--all
Show information about internal LVs. These are components
of normal LVs, such as mirrors, which are not
independently accessible, e.g. not mountable.
-b
|--blockdevice
No longer used.
--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.
--ignorelockingfailure
Allows a command to continue with read-only metadata
operations after locking failures.
--lockopt
String
Used to pass options for special cases to lvmlockd. See
lvmlockd(8) for more information.
--longhelp
Display long help text.
--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.
--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.
-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.
