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.

USAGE

       lvm lvpoll --polloperation pvmove|convert|merge|merge_thin LV ...
           [ -A|--autobackup y|n ]
           [ -i|--interval Number ]
           [    --abort ]
           [    --handlemissingpvs ]
           [ COMMON_OPTIONS ]

       Common options for lvm:
           [ -d|--debug ]
           [ -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

--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 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.

--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.

--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.

--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: 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

       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
