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 in-
formation 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 in-
formation.
--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 dis-
abling all metadata writing but nevertheless returning success to the calling func-
tion. 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 re-
fer 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 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 com-
mand, 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
