PVRESIZE(8) System Manager's Manual PVRESIZE(8)
NAME
pvresize — Resize physical volume(s)
SYNOPSIS
pvresize position_args
[ option_args ]
DESCRIPTION
pvresize resizes a PV. The PV may already be in a VG and may have active
LVs allocated on it.
USAGE
pvresize PV ...

[ COMMON_OPTIONS ]
Common options for lvm:
[ -d|--debug ]
[ -h|--help ]
[ -q|--quiet ]
[ -t|--test ]
[ -v|--verbose ]
[ -y|--yes ]
[ --commandprofile String ]
[ --config String ]
[ --devices PV ]
[ --devicesfile String ]
[ --driverloaded y|n ]
[ --journal String ]
[ --lockopt String ]
[ --longhelp ]
[ --nohints ]
[ --nolocking ]
[ --profile String ]
[ --version ]
OPTIONS
--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) set-
tings. The String arg uses the same format as lvm.conf(5), or
may use section/field syntax. See lvm.conf(5) for more informa-
tion 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
Restricts the devices that are visible and accessible to the com-
mand. 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) com-
mand. This overrides the lvm.conf(5) devices/devicesfile and de-
vices/use_devicesfile settings.
--driverloaded y|n
If set to no, the command will not attempt to use device-mapper.
For testing and debugging.
-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.
--lockopt String
Used to pass options for special cases to lvmlockd. See lvm-
lockd(8) for more information.
--longhelp
Display long help text.
--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 pro-
duce incorrect results.
--profile String
An alias for --commandprofile or --metadataprofile, depending on
the command.
-q|--quiet ...
Suppress output and log messages. Overrides --debug and --ver-
bose. Repeat once to also suppress any prompts with answer 'no'.
--reportformat basic|json|json_std
Overrides current output format for reports which is defined
globally by the report/output_format setting in lvm.conf(5). ba-
sic 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. json_std produces report output in JSON format
which is more compliant with JSON standard. See lvmreport(7) for
more information.
--setphysicalvolumesize Size[m|UNIT]
Overrides the automatically detected size of the PV. Use with
care, or prior to reducing the physical size of the device.
-t|--test
Run in test mode. Commands will not update metadata. This is im-
plemented by disabling all metadata writing but nevertheless re-
turning 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 de-
tail 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.)
VARIABLES
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 ex-
tents (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 con-
tent.
Size[UNIT]
Size is an input number that accepts an optional unit. Input
units are always treated as base two values, regardless of capi-
talization, e.g. 'k' and 'K' both refer to 1024. The default in-
put unit is specified by letter, followed by |UNIT. UNIT repre-
sents 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 pa-
rameter.
NOTES
pvresize will refuse to shrink a PV if it has allocated extents beyond
the new end.
EXAMPLES
Expand a PV after enlarging the partition.
pvresize /dev/sda1
Shrink a PV prior to shrinking the partition (ensure that the PV size is
appropriate for the intended new partition size).
pvresize --setphysicalvolumesize 40G /dev/sda1
