It might require a vgexport then vgimport to fix.
vgimport man page:
DESCRIPTION vgimport allows you to make a Volume Group that was previously exported using vgexport(8) known to the system again, perhaps after moving its Physical Volumes from a different machine. vgexport clears the VG sys‐ tem ID, and vgimport sets the VG system ID to match the host running vgimport (if the host has a system ID).
