The only way I can think of to do it automatically is to use the repair tool for the filesystem. You would probably have to create another PV to replace the failed one, (zero it first) give it the same UID and recreate the volume with the new PV in the correct place. Then let e2fsck (if an ext2 filesystem) find whatever it can. It would be nice to make copies of the good PVs in case this doesn't work satisfactorily if you have the space. Or would a snapshot help here? You might ask on the filesystem specific mailing list if this has any chance. HTH
