VGCONVERT(8) System Manager's Manual VGCONVERT(8)
vgconvert - Change volume group metadata format
vgconvert position_args
[ option_args ]
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.

[ --version ]
--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
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.
-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).
--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.
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.)
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: 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.)
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.
