+=========================
+A pvmove implementation is now available for the new metadata format.
+
+When running a command that allocates space (e.g. lvcreate), you can now
+restrict not only which disk(s) may be used but also the Physical Extents 
+on those disks.  e.g. lvcreate -L 10 vg1 /dev/hda6:1000-2000:3000-4000

 Description: The Linux Logical Volume Manager
 This is LVM2, the rewrite of The Linux Logical Volume Manager.  LVM
 supports enterprise level volume management of disk and disk subsystems
 by grouping arbitrary disks into volume groups. The total capacity of
 volume groups can be allocated to logical volumes, which are accessed as
 regular block devices.
+ .
+ LVM2 is currently stable, but has some unimplemented features (most notably,
+ pvmove and e2fsadm).  It is not yet recommended for production use.  It is
+ backwards-compatible with LVM1 (lvm10), and requires Linux kernel 2.4.

+.SH NAME
+pvmove \- move physical extents
+.SH SYNOPSIS
+.B pvmove
+[\-d/\-\-debug] [\-h/\-\-help] [\-i/\-\-interval Seconds] [\-v/\-\-verbose]
+[\-n/\-\-name LogicalVolume] SourcePhysicalVolume 
+[DestinationPhysicalVolume[:PE[-PE]...]...]
+.SH DESCRIPTION
+.B pvmove
+allows you to move the allocated physical extents (PEs) on
+.I SourcePhysicalVolume
+to one or more other physical volumes (PVs).
+You can optionally specify a source
+.I LogicalVolume
+in which case only extents used by that LV will be moved to 
+free (or specified) extents on
+.IR DestinationPhysicalVolume (s).
+If no
+.I DestinationPhysicalVolume
+is specifed, the normal allocation rules for the volume group are used.
+
+If \fBpvmove\fP gets interrupted for any reason, it will probably be 
+necessary to run \fBvgcfgrestore\fP to restore the volume group's metadata to
+the state it was before the \fBpvmove\fP began.
+
+\fBpvmove\fP locks the volume group and other LVM2 commands can't access
+the volume group metadata until \fBpvmove\fP has completed.
+
+.SH OPTIONS
+.TP
+.I \-i, \-\-interval Seconds
+Report progress as a percentage at regular intervals.
+.TP
+.I \-n, \-\-name " \fILogicalVolume\fR"
+Move only the extents belonging to
+.I LogicalVolume
+from
+.I SourcePhysicalVolume
+instead of all allocated extents to the destination physical volume(s).
+
+.SH EXAMPLES
+To move all logical extents of any logical volumes on
+.B /dev/hda4
+to free physical extents elsewhere in the volume group, giving verbose
+runtime information, use:
+.sp
+\	pvmove -v /dev/hda4

+.I \-\-removemissing
+Removes all missing physical volumes from the volume group and makes 
+the volume group consistent again.  
+
+It's a good idea to run this option with --test first to find out what it 
+would remove before running it for real.  
+
+Any logical volumes and dependent snapshots that were partly on the 
+missing disks get removed completely. This includes those parts 
+that lie on disks that are still present.
+
+If your logical volumes spanned several disks including the ones that are
+lost, you might want to try to salvage data first by activating your
+logical volumes with --partial as described in \fBlvm (8)\fP.
