Need a clue about what appears to be a phantom duplicate osd automagically created/discovered via the upgrade process -- which blocks the upgrade. The upgrade process on a known-good 19.2.2 to 19.2.3 proceeded normally through the mgrs and mons. It upgraded most of the osds, then stopped with the complaint "Error: UPGRADE_REDEPLOY_DAEMON: Upgrading daemon osd.1 on host noc3 failed." The roster in the "Daemon Versions" table on the dashboard looks normal except: There are two entries for 'osd.1' One of them has the correct version number, 19.2.2, the other is blank. The upgrade appears 'stuck'. An attempt to 'resume' resulted in the same error. The cluster operations are normal with all osds up and in. The cluster is ipv6.
