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 ...[ --reportformat basic|json ]
[ COMMON_OPTIONS ]
Common options for lvm:
[ -h|--help ]
[ -q|--quiet ]
[ -t|--test ]
[ -v|--verbose ]
[ -y|--yes ]
[ --commandprofile String ]
[ --config String ]
[ --driverloaded y|n ]
[ --lockopt String ]
[ --longhelp ]
[ --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 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.
-h|--help
Display help text.
--lockopt String
Used to pass options for special cases to lvmlockd. See lvmlockd(8) for
more information.
--longhelp
Display long help text.
--nolocking
Disable locking.
--profile String
An alias for --commandprofile or --metadataprofile, depending on the
command.
-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.
--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 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.)
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 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:
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.)
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.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
