NAME <\/a> <\/h2>\n

lvm lvpoll \u2212 Continue already initiated poll operation on a logical volume<\/p>\n

SYNOPSIS <\/a> <\/h2>\n

lvm lvpoll<\/b> option_args position_args<\/i>
[ option_args<\/i> ]<\/p>\n

DESCRIPTION <\/a> <\/h2>\n

lvm lvpoll is an internal command used by lvmpolld<\/b>(8) to monitor and complete lvconvert<\/b>(8) and pvmove<\/b>(8) operations. lvpoll itself does not initiate these operations and should not normally need to be run directly.<\/p>\n

 <\/td>\n<\/tr>\n<\/table>\n

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.

VARIABLES <\/a> <\/h2>\n

\n
<\/td>\n<\/td>\n <\/td>\n<\/tr>\n
<\/td>\n\n

LV<\/i><\/p>\n<\/td>\n

 <\/td>\n<\/tr>\n<\/table>\n

Logical Volume name. See lvm<\/b>(8) for valid names. An LV positional arg generally includes the VG name and LV name, e.g. VG\/LV.<\/p>\n\n\n
<\/td>\n\n

String<\/i><\/p>\n<\/td>\n

 <\/td>\n<\/tr>\n<\/table>\n

See the option description for information about the string content.<\/p>\n\n\n
<\/td>\n\n

Size<\/i>[UNIT]<\/p>\n<\/td>\n

 <\/td>\n<\/tr>\n<\/table>\n

Size is an input number that accepts an optional unit. Input units are always treated as base two values, regardless of capitalization, e.g. \u2019k\u2019 and \u2019K\u2019 both refer to 1024. The default input unit is specified by letter, followed by |UNIT. UNIT represents other possible input units: bBsSkKmMgGtTpPeE<\/b>. 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 \u2212\u2212units, where capital letters mean multiple of 1000.)<\/p>\n

ENVIRONMENT VARIABLES <\/a> <\/h2>\n

See lvm<\/b>(8) for information about environment variables used by lvm. For example, LVM_VG_NAME can generally be substituted for a required VG parameter.<\/p>\n

NOTES <\/a> <\/h2>\n

To find the name of the pvmove LV that was created by an original pvmove \/dev\/name<\/b> command, use the command:
lvs \u2212a \u2212S move_pv=\/dev\/name<\/b>.<\/p>\n

Continue polling a pvmove operation.
lvm lvpoll \u2212\u2212polloperation pvmove vg00\/pvmove0<\/b><\/p>\n

Abort a pvmove operation.
lvm lvpoll \u2212\u2212polloperation pvmove \u2212\u2212abort vg00\/pvmove0<\/b><\/p>\n
