LVM(LVPOLL) Red Hat, Inc. 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.
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 ]
[ --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 set-
tings. 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 lvm-
lockd(8) for more information.
--longhelp
Display long help text.
--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 --ver-
bose. 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 posi-
tional arg generally includes the VG name and LV name, e.g.
VG/LV.
String
See the option description for information about the string con-
tent.
Size[UNIT]
Size is an input number that accepts an optional unit. Input
units are always treated as base two values, regardless of capi-
talization, e.g. 'k' and 'K' both refer to 1024. The default
input unit is specified by letter, followed by |UNIT. UNIT rep-
resents other possible input units: bBsSkKmMgGtTpPeE. b|B is
bytes, s|S is sectors of 512 bytes, k|K is kilobytes, m|M is
megabytes, g|G is gigabytes, t|T is terabytes, p|P is petabytes,
e|E is exabytes. (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
