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 ...
[ -i|--interval Number ]
[ --abort ]
[ --handlemissingpvs ]
[ COMMON_OPTIONS ]
Common options for lvm:
[ -h|--help ]
[ -q|--quiet ]
[ -t|--test ]
[ -v|--verbose ]
[ -y|--yes ]
[ --commandprofile String ]
[ --config String ]
[ --devices PV ]
[ --devicesfile String ]
[ --driverloaded y|n ]
[ --journal String ]
[ --lockopt String ]
[ --longhelp ]
[ --nohints ]
[ --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(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
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.
--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
