resize LVM partition on VM

I don't know the steps which ended up in this position, but I currently have some extra space from resizing the virtual volume in VMWare. I think we tried using fdisk or parted on an ubuntu VM. But I am currently seeing this when I 'print' from 'parted'

Number  Start   End    Size   Type      File system  Flags
 1      1049kB  256MB  255MB  primary   ext2         boot
 2      257MB   295GB  295GB  extended
 5      257MB   133GB  133GB  logical                lvm

How can I get the extra space from the 295GB extended partition to show up in the lvm? Here is the fstab:

/dev/mapper/cmail-root /               ext4    errors=remount-ro 0       1
UUID=2518f444-6a6d-4fff-8c42-da640ad95655 /boot           ext2    defaults,acl        0       2
/dev/mapper/cmail-swap_1 none            swap    sw              0       0

Here is the fdisk -l dump:

You can see the non-valid partition tables on 2 volumes. Any diagnosis about this? Thanks.
