\fBlvmdiskscan\fP

[ \fIoption_args\fP ]

|
|
.SH 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 \fBlvm.conf\fP(5) to restrict
|
|
the scan to avoid a CD ROM, for example.
|
|
|
|
This command is deprecated, use \fBpvs\fP instead.

\fB--config\fP \fIString\fP
|

.br
|

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 \fBlvm.conf\fP(5) for more information about config.

|
|
.ad l
|
|
\fB-d\fP|\fB--debug\fP ...
|
|
.br
|

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).
|
|
.ad b
|
|
.HP
|
|
.ad l
|
|
\fB--devices\fP \fIPV\fP
|
|
.br
|
|
Devices that the command can use. This option can be repeated
|
|
or accepts a comma separated list of devices. This overrides
|
|
the devices file.
|
|
.ad b
|
|
.HP
|
|
.ad l
|
|
\fB--devicesfile\fP \fIString\fP
|
|
.br
|
|
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 devices/devicesfile and
|
|
devices/use_devicesfile settings.

.HP
|
|
.ad l
|
|
\fB--driverloaded\fP \fBy\fP|\fBn\fP
|
|
.br
|
|
If set to no, the command will not attempt to use device-mapper.
|
|
For testing and debugging.

\fB--nolocking\fP

.ad b

|
|
.ad l
|
|
\fB--profile\fP \fIString\fP
|
|
.br
|

An alias for --commandprofile or --metadataprofile, depending
|
|
on the command.
|
|
.ad b
|
|
.HP
|
|
.ad l
|
|
\fB-q\fP|\fB--quiet\fP ...
|
|
.br
|
|
Suppress output and log messages. Overrides --debug and --verbose.
|
|
Repeat once to also suppress any prompts with answer 'no'.
|
|
.ad b
|
|
.HP
|
|
.ad l
|
|
\fB--readonly\fP
|
|
.br
|
|
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.
|
|
.ad b
|
|
.HP
|
|
.ad l
|
|
\fB-t\fP|\fB--test\fP
|
|
.br
|
|
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.
|
|
.ad b
|
|
.HP
|
|
.ad l
|
|
\fB-v\fP|\fB--verbose\fP ...
|
|
.br
|
|
Set verbose level. Repeat from 1 to 4 times to increase the detail
|
|
of messages sent to stdout and stderr.
|
|
.ad b
|
|
.HP
|
|
.ad l
|
|
\fB--version\fP
|
|
.br
|
|
Display version information.
|
|
.ad b
|
|
.HP
|
|
.ad l
|
|
\fB-y\fP|\fB--yes\fP
|
|
.br
|
|
Do not prompt for confirmation interactively but always assume the
|
|
answer yes. Use with extreme caution.
|
|
(For automatic no, see -qq.)

.SH VARIABLES
|
|
.HP

\fIString\fP

.br
|
|
See the option description for information about the string content.
|
|
.HP
|
|
\fISize\fP[UNIT]
|
|
.br
|
|
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: \fBbBsSkKmMgGtTpPeE\fP.
|
|
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.)
|
|
.SH ENVIRONMENT VARIABLES
|
|
See \fBlvm\fP(8) for information about environment variables used by lvm.
|
|
For example, LVM_VG_NAME can generally be substituted for a required VG parameter.
