From c66d5babb1e283869ba0f1f59029bead5ca5f37d Mon Sep 17 00:00:00 2001 From: Sage Weil Date: Thu, 26 Jan 2017 14:22:53 -0500 Subject: [PATCH] os/bluestore: fix statfs to not include DB partition in free space If we report the DB space as vailable, ceph thinks the OSD can store more data and will not mark the cluster as full as easily. And in reality, we can't actually store data in this space--only metadata. Avoid the problem by not reporting it as available.
