+Subject: [PATCH] devices file: do not clear PVID of unread devices
+
+In a certain disconnected state, a block device is present on
+the system, can be opened, reports a valid size, reports the
+correct device id (wwid), and matches a devices file entry.
+But, reading the device can still fail.  In this case,
+device_ids_validate() was misinterpreting the read error as
+the device having no data/label on it (and no PVID).
+The validate function would then clear the PVID from the
+devices file entry for the device, thinking that it was
+fixing the devices file (making it consistent with the on disk
+state.)  Fix this by not attempting to check and correct a
+devices file entry that cannot be read.  Also make this case
+explicit in the hints validation code (which was doing the
+right thing but indirectly.)
