Also, automatic re-balance is disallowed if the physical volume(s) have pre-allocated extents associated

with them, for snapshots in group volume version 2.2 or higher.

See lvm(7) for more information on snapshot volumes.

Options and Arguments

pvmove recognizes the following options and arguments:

dest_pv_path Speciﬁes the block device path name of a physical volume. It cannot be the

source physical volume. It must be in the same volume group as

source_pv_path.

dest_pvg_name Speciﬁes the name of a physical volume group. It must be in the same volume

group as source_pv_path.

For volume group version 2.0 and higher, a physical volume group can be pro-

vided along with the

-a option, only when one or more logical volumes is

speciﬁed. Also, the physical volume group must be in the same volume group

where the logical volume resides.

de The starting location of the destination physical extents within a destination

physical volume. If this starting location is provided along with the

dest_pv_path , then the source physical extents are re-allocated to the destina-

tion physical volume starting from this location.

The

pvmove command fails with an error if the requested number of extents

for relocation on the destination physical volume are not available contigu-

ously starting from this location.

lv_path Speciﬁes the block device path name of a logical volume.

pv_path Speciﬁes the block device path name of a physical volume.

se1[-se2] The source physical extent range. If the extent range is provided along with

source_pv_path, then the extents from se1 to se2 are moved out of the source

physical volume. A single extent can also be provided, speciﬁed by only se1

instead of the extent range.

source_pv_path The block device path name of a physical volume.

vg_name Speciﬁes the path name of a volume group.

-a Performs the requested pvmove operation in automatic re-balance mode.

-a vg_name Performs an automatic re-balance of allocated extents within a volume group.

-a lv_path [pv_path...]

Performs an automatic re-balance of allocated extents within a volume group

for the speciﬁed logical volumes. If pv_path is also speciﬁed along with

-a

lv_path, then the automatic re-balance for the logical volume is performed

only across the speciﬁed physical volumes.

-A autobackup Set automatic backup for this invocation of this command. autobackup can

have one of the following values:

y Automatically back up conﬁguration changes made to the physical

volume. This is the default.

After this command executes, the

vgcfgbackup command (see

vgcfgbackup (1M)) is executed for the volume group to which the physical

volume belongs.

n Do not back up conﬁguration changes this time.

-e no_of_extents Moves the last few extents speciﬁed by no_of_extents from the source physical

volume.

This option should not be used in conjunction with the

-n option or when

source physical extent range is provided, speciﬁed by se1[-se2}.

This option cannot be used when

-a option is speciﬁed.

-f pv_path Moves the allocated physical extents from the speciﬁed physical volumes to the

remaining physical volumes in the volume group such that the remaining
