+# Old versions would automatically clear MISSING_PV on a PV that had no mda,

+# validity of the data on the device.  I suspect that at some point in the
+# past, the MISSING_PV flag was used to decide if metadata could be used
+# from the device, so the flag could be cleared on a PV with no mda.
+# These days lvm knows when to ignore outdated metadata.
+# MISSING_PV probably has little to no value for determining valid data either,
+# so it's likely that we'll begin to automatically clear MISSING_PV in the
+# future (but it will have nothing to do with having mdas.)
