From a922d38fd10d55d5033f10df15baf966e8f5b18c Mon Sep 17 00:00:00 2001 From: Sage Weil Date: Sat, 29 May 2010 09:41:23 -0700 Subject: ceph: close out mds, osd connections before stopping auth The auth module (part of the mon_client) is needed to free any ceph_authorizer(s) used by the mds and osd connections. Flush the msgr workqueue before stopping monc to ensure that the destroy_authorizer auth op is available when those connections are closed out.
