NAME
lvmdiskscan — List devices that may be used as physical volumes
SYNOPSIS
lvmdiskscan
[ option_args ]
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.
USAGE

[ -v|--verbose ]
[ -y|--yes ]
[ --commandprofile String ]

[ --journal String ]
[ --lockopt String ]
[ --longhelp ]
[ --nohints ]
[ --nolocking ]
[ --profile String ]
[ --version ]
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
Restricts the devices that are visible and accessible to the command. Devices not listed will
appear to be missing. 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. Use with caution, concurrent commands may produce incorrect results.
--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.)
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.)
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.
