# lvm-lvpoll

## NAME



           lvm lvpoll — Continue already initiated poll operation on a
           logical volume
    


## SYNOPSIS



           **lvm lvpoll** _option_args position_args_
               [ _option_args_ ]
    


## DESCRIPTION



           lvm lvpoll is an internal command used by lvmpolld(8) to monitor
           and complete lvconvert(8) and pvmove(8) operations. lvpoll itself
           does not initiate these operations and should not normally need to
           be run directly.

## OPTIONS



    
           **--abort**
                  Stop processing a poll operation in lvmpolld.
    
           **-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).
    
           **--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.
    
           **--handlemissingpvs**
                  Allows  a  polling  operation  to  continue  when  PVs  are
                  missing, e.g. for repairs due to faulty devices.
    
           **-h** |**--help**
                  Display help text.
    
           **-i** |**--interval** _Number_
                  Report progress at regular intervals.
    
           **--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.
    
           **--polloperation pvmove** |**convert** |**merge** |**merge_thin**
                  The command to perform from lvmpolld.
    
           **--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'.
    
           **-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



           _LV_     Logical Volume name.  See lvm(8) for valid names.  An LV
                  positional arg generally includes the VG name and LV name,
                  e.g. VG/LV.
    
           _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



           To find the name of the pvmove LV that was created by an original
           **pvmove /dev/name** command, use the command:
           **lvs -a -S move_pv=/dev/name**.
    


## EXAMPLES



           Continue polling a pvmove operation.
           **lvm lvpoll --polloperation pvmove vg00/pvmove0**
    
           Abort a pvmove operation.
           **lvm lvpoll --polloperation pvmove --abort vg00/pvmove0**
    
           Continue polling a mirror conversion.
           **lvm lvpoll --polloperation convert vg00/lvmirror**
    
           Continue mirror repair.
           **lvm lvpoll --polloperation convert vg/damaged_mirror**
           **--handlemissingpvs**
    
           Continue snapshot merge.
           **lvm lvpoll --polloperation merge vg/snapshot_old**
    
           Continue thin snapshot merge.
           **lvm lvpoll --polloperation merge_thin vg/thin_snapshot**
