.SH DESCRIPTION
.
lvm lvpoll is an internal command used by \fBlvmpolld\fP(8) to monitor and
complete \fBlvconvert\fP(8) and \fBpvmove\fP(8) operations. lvpoll itself
does not initiate these operations and should not normally need to be run
directly.

.SH OPTIONS
.
.TP
.O_abort
Stop processing a poll operation in lvmpolld.
.
.TP
.O_autobackup
Specifies if metadata should be backed up automatically after a change.
Enabling this is strongly advised!
See \fBvgcfgbackup\fP(8) for more information.
.
.TP
.O_commandprofile
The command profile to use for command configuration.
See \fBlvm.conf\fP(5) for more information about profiles.
.
.TP
.O_config
Config settings for the command. These override \fBlvm.conf\fP(5) settings.
The String arg uses the same format as \fBlvm.conf\fP(5),
or may use section/field syntax.
See \fBlvm.conf\fP(5) for more information about config.
.
.TP
.O_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).
.
.TP
.O_devices
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.
.
.TP
.O_devicesfile
A file listing devices that LVM should use.
The file must exist in \fI/etc/lvm/devices/\fP and is managed
with the \fBlvmdevices\fP(8) command.
This overrides the \fBlvm.conf\fP(5) \fBdevices/devicesfile\fP and
\fBdevices/use_devicesfile\fP settings.
.
.TP
.O_driverloaded
If set to no, the command will not attempt to use device-mapper.
For testing and debugging.
.
.TP
.O_handlemissingpvs
Allows a polling operation to continue when PVs are missing,
e.g. for repairs due to faulty devices.
.
.TP
.O_help
Display help text.
.
.TP
.O_interval
Report progress at regular intervals.
.
.TP
.O_journal
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.
.
.TP
.O_lockopt
Used to pass options for special cases to lvmlockd.
See \fBlvmlockd\fP(8) for more information.
.
.TP
.O_longhelp
Display long help text.
.
.TP
.O_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.
.
.TP
.O_nolocking
Disable locking. Use with caution, concurrent commands may produce
incorrect results.
.
.TP
.O_polloperation
The command to perform from lvmpolld.
.
.TP
.O_profile
An alias for \-\-commandprofile or \-\-metadataprofile, depending
on the command.
.
.TP
.O_quiet
Suppress output and log messages. Overrides \-\-debug and \-\-verbose.
Repeat once to also suppress any prompts with answer 'no'.
.
.TP
.O_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.
.
.TP
.O_verbose
Set verbose level. Repeat from 1 to 4 times to increase the detail
of messages sent to stdout and stderr.
.
.TP
.O_version
Display version information.
.
.TP
.O_yes
Do not prompt for confirmation interactively but always assume the
answer yes. Use with extreme caution.
(For automatic no, see \-qq.)
.
.SH VARIABLES
.
.TP
.I LV
Logical Volume name.  See \fBlvm\fP(8) for valid names.
An LV positional arg generally includes the VG name and LV name, e.g. VG/LV.
.
.TP
.I String
See the option description for information about the string content.
.
.TP
.IR 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:
.BR b | B
is bytes,
.BR s | S
is sectors of 512 bytes,
.BR k | K
is KiB,
.BR m | M
is MiB,
.BR g | G
is GiB,
.BR t | T
is TiB,
.BR p | P
is PiB,
.BR e | E
is EiB.
(This should not be confused with the output control \-\-units,
where capital letters mean multiple of 1000.)
.
.SH ENVIRONMENT VARIABLES
.
See \fBlvm\fP(8) for information about environment variables used by lvm.
For example, \fBLVM_VG_NAME\fP can generally be substituted
for a required VG parameter.
.
.SH NOTES
.
To find the name of the pvmove LV that was created by an original
\fBpvmove /dev/name\fP command, use the command:
.br
\fBlvs \-a \-S move_pv=/dev/name\fP.
.
.SH EXAMPLES
.
Continue polling a pvmove operation.
.br
.B lvm lvpoll \-\-polloperation pvmove vg00/pvmove0
.P
Abort a pvmove operation.
.br
.B lvm lvpoll \-\-polloperation pvmove \-\-abort vg00/pvmove0
.P

.br
.B lvm lvpoll \-\-polloperation convert vg00/lvmirror
.P
Continue mirror repair.
.br
.B lvm lvpoll \-\-polloperation convert vg/damaged_mirror \-\-handlemissingpvs
.P
Continue snapshot merge.
.br
.B lvm lvpoll \-\-polloperation merge vg/snapshot_old
.P
Continue thin snapshot merge.
.br
.B lvm lvpoll \-\-polloperation merge_thin vg/thin_snapshot
