NAME
vgextend — Add physical volumes to a volume group
SYNOPSIS
vgextend position_args
[ option_args ]
DESCRIPTION
vgextend adds one or more PVs to a VG. This increases the space available for LVs in the
VG.
Also, PVs that have gone missing and then returned, e.g. due to a transient device
failure, can be added back to the VG without re-initializing them (see --restoremissing).
If the specified PVs have not yet been initialized with pvcreate, vgextend will initialize
them. In this case pvcreate options can be used, e.g. --labelsector, --metadatasize,
--metadataignore, --pvmetadatacopies, --dataalignment, --dataalignmentoffset.

OPTIONS
-A|--autobackup y|n
Specifies if metadata should be backed up automatically after a change. Enabling
this is strongly advised! See vgcfgbackup(8) for more information.
--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.
--dataalignment Size[k|UNIT]
Align the start of a PV data area with a multiple of this number. To see the
location of the first Physical Extent (PE) of an existing PV, use pvs -o +pe_start.
In addition, it may be shifted by an alignment offset, see --dataalignmentoffset.
Also specify an appropriate PE size when creating a VG.
--dataalignmentoffset Size[k|UNIT]
Shift the start of the PV data area by this additional offset.
-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.
-f|--force ...
Override various checks, confirmations and protections. Use with extreme caution.
-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.
--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.
--metadataignore y|n
Specifies the metadataignore property of a PV. If yes, metadata areas on the PV
are ignored, and lvm will not store metadata in the metadata areas of the PV. If
no, lvm will store metadata on the PV.
--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.
--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.
--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.
--restoremissing
Add a PV back into a VG after the PV was missing and then returned, e.g. due to a
transient failure. The PV is not reinitialized.
-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.)
-Z|--zero y|n
Controls if the first 4 sectors (2048 bytes) of the device are wiped. The default
is to wipe these sectors unless either or both of --restorefile or --uuid are
specified.
VARIABLES
VG Volume Group name. See lvm(8) for valid names.
PV Physical Volume name, a device path under /dev. For commands managing physical
extents, a PV positional arg generally accepts a suffix indicating a range (or
multiple ranges) of physical extents (PEs). When the first PE is omitted, it
defaults to the start of the device, and when the last PE is omitted it defaults to
end. Start and end range (inclusive): PV[:PE-PE]... Start and length range
(counting from 0): PV[:PE+PE]...
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.
EXAMPLES
Add two PVs to a VG.
vgextend vg00 /dev/sda4 /dev/sdn1
