# pvresize

## 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.

## 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)
                  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.
    
           **-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
                  lvmlockd(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.
    
           **--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(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.
    
           **--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: **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.
    


## 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**
