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.
The command profile to use for command configuration. See
lvm.conf(5) for more information about profiles.
Config settings for the command. These override lvm.conf
settings. The String arg uses the same format as lvm.conf, or
may use section/field syntax. See lvm.conf(5) for more
information about config.
Set debug level. Repeat from 1 to 6 times to increase the
detail of messages sent to the log file and/or syslog (if
If set to no, the command will not attempt to use device-
mapper. For testing and debugging.

Used to pass options for special cases to lvmlockd. See
lvmlockd(8) for more information.
Display long help text.
Only report PVs.
An alias for --commandprofile or --metadataprofile, depending
on the command.
Suppress output and log messages. Overrides --debug and
--verbose. Repeat once to also suppress any prompts with
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.
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
Set verbose level. Repeat from 1 to 4 times to increase the
detail of messages sent to stdout and stderr.

Do not prompt for confirmation interactively but always assume
the answer yes. Use with extreme caution. (For automatic no,
See the option description for information about the string
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: bBsSkKmMgGtTpPeE.
b|B is bytes, s|S is sectors of 512 bytes, k|K is kilobytes,
m|M is megabytes, g|G is gigabytes, t|T is terabytes, p|P is
petabytes, e|E is exabytes. (This should not be confused with
the output control --units, where capital letters mean
multiple of 1000.)
