Getting placement groups to be placed evenly continues to be a major
challenge for us, bordering on impossible.
When we first reported trouble with this, the ceph cluster had 12
OSD's (each Intel DC S3700 400GB) spread across three nodes. Since
then, it has grown to 8 nodes with 38 OSD's.

Hi Vickey,
Sorry about the issues you've been seeing. This looks very similar to
http://tracker.ceph.com/issues/11104 .
Here are two options you can try in order to work around this:
- If you must run Firefly (0.80.x) or Giant (0.87.x), please try
enabling the "epel-testing" repository on your s

This major release is expected to form the basis of the next long-term
stable series. It is intended to supercede v0.80.x Firefly.
Highlights since Giant include:
* RADOS Performance: a range of improvements have been made in the
OSD and client-side librados code that improve the throughput on
I'm not sure about Centos 7.0 but Ceph is not part of the 6.5 distro.

Loic,
You're not mistaken the pages are listed under the Installation (Manual) link:

You'll see the first link is the "Get Packages" link which takes you to:

I'm not having much luck here. Is there a possibility that the imported PGs
aren't being picked up because the MONs think that they're older than the empty
PGs I find on the up OSDs?
I feel that I'm so close to *not* losing my RBD volume because I only have two
bad PGs and I've successfully exp

I spend a bunch of time figuring out ways to graph dense data sets for my
monitoring, and I have to say that graph is a thing of beauty. I'll
definitely be adding something similar to my ceph cluster monitoring
deployment.

Whatever the version you tested, ceph won't recover data when you
manually stop osd immediately. And it will trigger mark down osd out
when it reach "mon_osd_down_out_interval" seconds.
