LVMDISKSCAN(8) System Manager's Manual LVMDISKSCAN(8)
lvmdiskscan — List devices that may be used as physical volumes
lvmdiskscan
[ option_args ]
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.
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 ]
[ --journal String ]
[ --lockopt String ]
[ --longhelp ]
[ --nohints ]
[ --nolocking ]
[ --profile String ]
[ --version ]
--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.
--journal String
Record information in the systemd journal. This
information is in addition to information enabled by the
lvm.conf log/journal setting. command: record information
about the command. output: record the default command
output. debug: record full command debugging.
--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.
--nohints
Do not use the hints file to locate devices for PVs. A
command may read more devices to find PVs when hints are
not used. The command will still perform standard hint file
invalidation where appropriate.
--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.)
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.)
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.
