I seem to recall, when faced with a similar situation, that I had to start fresh.

backup the data
remove logical volume (which removes the data)
rebuild (to new size) the logical volume
restore the data

NAME
vgcfgbackup - backup volume group descriptor area SYNOPSIS
vgcfgbackup [-d|--debug] [-f|--file filename] [-h|--help] [--ignorelockingfailure] [-P|--partial] [-v|--verbose] [VolumeGroupName...] DESCRIPTION
vgcfgbackup allows you to backup the metadata of your volume groups. If you don't name any volume groups on the command line, all of them will be backed up. In a default installation, each volume group gets backed up into a separate file bearing the name of the volume group in the directory /etc/lvm/backup. You can write the backup to an alternative file using -f. In this case if you are backing up more than one volume group the filename is treated as a template, and %s gets replaced by the volume group name. NB. This DOESN'T backup user/system data in logical volume(s)! Backup /etc/lvm regularly too. OPTIONS
See lvm for common options. SEE ALSO
