Doc Text: |
Cause: Ceph's filestore_xfs_extsize setting reduces OSD fragmentation at the expense of large sequential write performance. This option is enabled by default in RHCS 1.3. As a consequence, Ceph's large sequential write performance is degraded in comparison to RHCS 1.2. The filestore_xfs_extsize setting is now disabled by default in RHCS 1.3, and Ceph's large sequential write performance is improved.

Upstream PR @ https://github.com/ceph/ceph/pull/7265 - Mark, could you please review it? PR was merged upstream; need to cherry-pick to ceph-1.3.1-rhel-patches in Gerrit. Ubuntu build with this patch is ceph_0.94.3.3-1redhat1trusty (In reply to Ken Dreyer (Red Hat) from comment #5) > Ubuntu build with this patch is ceph_0.94.3.3-1redhat1trusty I had to bump the version number, so it's ceph_0.94.3.3-2redhat1trusty Marking this Bug as Verified as this was tested part of 1.3.1 Async Release. Confirmed this Fix was also part of 1.3.2 code base. ceph --admin-daemon /var/run/ceph/ceph-osd.1.asok config get filestore_xfs_extsize { "filestore_xfs_extsize": "false" } Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
