The data should still be on extents of the physical volumes.  The
simplist course of action is reconstructing the LVM metadata.

In the worst case, the data should be recoverable from the physical
extents by using dd to copy them in the proper order to the logical
volume of another volume group or to a raw partition of another disk.
