[ option_args ]
Описание (Description)
vgconvert is no longer a part of LVM. It was removed along with
support for the LVM1 format. Use an older version of LVM to
convert VGs from the LVM1 format to LVM2.

Параметры (Options)
--bootloaderareasize
Size[m|UNIT]
Reserve space for the bootloader between the LVM metadata
area and the first PE. The bootloader area is reserved
for bootloaders to embed their own data or metadata; LVM
will not use it. The bootloader area begins where the
first PE would otherwise be located. The first PE is
moved out by the size of the bootloader area, and then
moved out further if necessary to match the data
alignment. The start of the bootloader area is always
aligned, see also --dataalignment and
--dataalignmentoffset. The bootloader area may be larger
than requested due to the alignment, but it's never less
than the requested size. To see the bootloader area start
and size of an existing PV use pvs -o
+pv_ba_start,pv_ba_size.
--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.
-f
|--force
...
Override various checks, confirmations and protections.
Use with extreme caution.
-h
|--help
Display help text.
--labelsector
Number
By default the PV is labelled with an LVM2 identifier in
its second sector (sector 1). This lets you use a
different sector near the start of the disk (between 0 and
3 inclusive - see LABEL_SCAN_SECTORS in the source). Use
with care.
--lockopt
String
Used to pass options for special cases to lvmlockd. See
lvmlockd(8) for more information.
--longhelp
Display long help text.
--metadatasize
Size[m|UNIT]
The approximate amount of space used for each VG metadata
area. The size may be rounded.
-M
|--metadatatype lvm2
Specifies the type of on-disk metadata to use. lvm2
(or
just 2
) is the current, standard format. lvm1
(or just 1
)
is no longer used.
--nolocking
Disable locking.
--profile
String
An alias for --commandprofile or --metadataprofile,
depending on the command.
--pvmetadatacopies 0
|1
|2
The number of metadata areas to set aside on a PV for
storing VG metadata. When 2, one copy of the VG metadata
is stored at the front of the PV and a second copy is
stored at the end. When 1, one copy of the VG metadata is
stored at the front of the PV. When 0, no copies of the
VG metadata are stored on the given PV. This may be
useful in VGs containing many PVs (this places limitations
on the ability to use vgsplit later.)
-q
|--quiet
...
Suppress output and log messages. Overrides --debug and
--verbose. Repeat once to also suppress any prompts with
answer 'no'.
--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)
VG Volume Group name. See lvm(8) for valid names.
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.
