It hasn't, and that's my plan for now, to correct the metadata (UUID may be different), and then do that restore.

Don't do that. Had the LVM structure changed since the "mirror" disk last synced? If not, it should have the LVM metatadata, which can be restored, preferably to an image of the recent disk. Ideally, the only thing that would be done with the failed disk is to make an image of it on another drive. Then work with the image. dd_rescue may be useful for making the image.
