+Subject: [PATCH] Tell LVM DBus to refresh it's internal status during reset
+
+Unfortunately some users run wipefs <disk> thinking it's enough
+to remove all devices on top of the disk cleanly.
+In cases where the PV is not directly on the disk, LVM DBus
+doesn't get a udev event and doesn't remove the VG and LVs from
+DBus so we think these still exist.
+
+Resolves: RHEL-93967
