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

Stop processing a poll operation in lvmpolld.

Specifies if metadata should be backed up automatically after a change.
    Enabling this is strongly advised! See vgcfgbackup(8) for more information.

The command profile to use for command configuration.
    See lvm.conf(5) for more information about profiles.

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.

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).

Restricts the devices that are visible and accessible to the command.
    Devices not listed will appear to be missing. This option can be repeated, or accepts a comma separated list of devices. This overrides the devices file.

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.

If set to no, the command will not attempt to use device-mapper.
    For testing and debugging.

Allows a polling operation to continue when PVs are missing,
    e.g. for repairs due to faulty devices.

Display help text.

Report progress at regular intervals.
    With a '+' prefix, the first check is delayed by the given number of seconds, allowing background operations to start before polling begins.

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.

Used to pass options for special cases to lvmlockd.
    See lvmlockd(8) for more information.

Display long help text.

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.

Disable locking. Use with caution, concurrent commands may produce
    incorrect results.

The command to perform from lvmpolld.

An alias for --commandprofile or --metadataprofile, depending
    on the command.

Suppress output and log messages. Overrides --debug and --verbose.
    Repeat once to also suppress any prompts with answer 'no'.

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.

Set verbose level. Repeat from 1 to 4 times to increase the detail
    of messages sent to stdout and stderr.

Display version information.

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
