## OPTIONS



    
           **--addtag** _Tag_
                  Adds  a  tag to a PV, VG or LV. This option can be repeated
                  to add multiple tags at once. See  lvm(8)  for  information
                  about tags.
    
           **-a** |**--all**
                  Change all visible PVs.
    
           **-x** |**--allocatable y** |**n**
                  Enable  or  disable  allocation of physical extents on this
                  PV.
    
           **-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.
    
           **-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).
    
           **--deltag** _Tag_
                  Deletes  a  tag  from  a  PV,  VG or LV. This option can be
                  repeated to delete multiple tags at once.  See  lvm(8)  for
                  information about tags.
    
           **--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.
    
           **-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.
    
           **--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.
    
           **--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.
    
           **-S** |**--select** _String_
                  Select  objects  for  processing  and  reporting  based  on
                  specified criteria.  The criteria syntax  is  described  by
                  **--select  help** and  lvmreport(7).  For reporting commands,
                  one row is displayed for each object matching the criteria.
                  See **--options help** for selectable object fields.  Rows  can
                  be  displayed  with  an  additional  "selected"  field  (-o
                  selected) showing 1 if the row matches the selection and  0
                  otherwise.   For  non-reporting  commands which process LVM
                  entities, the selection is used to choose items to process.
    
           **-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.
    
           **-u** |**--uuid**
                  Generate new random UUID for specified PVs.
    
           **-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_]...
    
           _Select_ Select indicates that a required positional parameter can
                  be omitted if the **--select** option is used.  No arg appears
                  in this position.
    
           _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



           Disallow the allocation of physical extents on a PV (e.g. because
           of disk errors, or because it will be removed after freeing it).
           **pvchange -x n /dev/sdk1**
