Hi Peter
Currently I think that all this problems are related to missing or
broken pvscan --cache calls.
I found one problematic case regarding coldplug; I believe Redhat does
not longer use this code path. In none of my tests the "artificial" add
event triggers pvscan as it should. The udev rules test for
LVM_MD_PV_ACTIVATED, which is never set in this case. My quick fix is
to ignore if the event is actually change.
