From cd634fb6eec72ef8e6dd677546b8d0ffdd2501eb Mon Sep 17 00:00:00 2001 From: Sage Weil Date: Thu, 12 May 2011 09:29:18 -0700 Subject: [PATCH] libceph: subscribe to osdmap when cluster is full When the cluster is marked full, subscribe to subsequent map updates to ensure we find out promptly when it is no longer full. This will prevent us from spewing ENOSPC for (much) longer than necessary.
