From d7af21020e216311b5d89539f5c064bafe700d21 Mon Sep 17 00:00:00 2001 From: Sage Weil Date: Sun, 6 Feb 2011 20:49:59 -0800 Subject: [PATCH] mon: ignore mds boot messages with zeroed port On 0.24.2 I saw a zeroed port in the cmds log and in the mdsmap. Ignore anything from a cmds with a zeroed port to prevent the insanity from spreading.
