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

lvm lvpoll option_args position_args
[ option_args ]

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.

[ –version ]

–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.)

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.)

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.

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.

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
