LVM sometimes gives you freedom where you otherwise would have had none, but this is a VM, most likely you can expand your disk without LVM.

1.  Comment-out /ordata from /etc/fstab, and chkconfig the oracle services off.
2.  Reboot.  It should come up cleanly without that mountpoint.  The reboot isn't actually necessary, it just proves a point.  Guarantees you're able to dismount and guarantees nothing's using it.
3.  Log into the vm host, and snapshot.  It's always good to snapshot the volume before expanding it.
And then expand the volume.
4.  As appropriate, fdisk to expand partitions inside the volume.
5.  resize2fs
6.  Re-enable fstab and chkconfig.  Reboot.  It should all come up cleanly.
