It is not too difficult to get going, once you add various patches so it
works:
- missing __init__.py
- Allow to set ceph.conf
- Fix write issue: ioctx.write() does not return the written length
- Add param to async_update call (for swift in Juno)
There are a number of forks/pulls etc for

Hi Italo,
If you check for a post from me from a couple of days back, I have done exactly
this.
I created a k=5 m=3 over 4 hosts. This ensured that I could lose a whole host
and then an OSD on another host and the cluster was still fully operational.
I’m not sure if my method I used
Hi Lionel,
we have a ceph cluster with in sum about 1PB, 12 OSDs with 60 Disks,
devided into 4 racks in 2 rooms, all connected with a dedicated 10G
cluster network. Of course with a replication level of 3.
We did about 9 Month intensive testing. Just like you, we were never

Hi,
We've setup ceph and openstack on a fairly peculiar network
configuration (or at least I think it is) and I'm looking for
information on how to make it work properly.
Basically, we have 3 networks, a management network, a storage network
and a cluster network. The management network is
Hi,
I had an similiar effect two weeks ago - 1PG backfill_toofull and due
reweighting and delete there was enough free space but the rebuild
process stopped after a while.
After stop and start ceph on the second node, the rebuild process runs
without trouble and the backfill_toofull are gone.
Ken,
I had a number of issues installing Ceph on RHEL 7, which I think are
mostly due to dependencies. I followed the quick start guide, which
gets the latest major release--e.g., Firefly, Giant.
ceph.conf is here: http://goo.gl/LNjFp3
ceph.log common errors included: http://goo.gl/yL8UsM

Hi Nico,
I would probably recommend to upgrade to 0.87 (giant). I am running this
version for some time now and it works very well. I also upgraded from
firefly and it was easy.
The issue you are experiencing seems quite complex and it would require
debug logs to troubleshoot.
Apology
Have you looked at

Hi all,
I didn't actually calculate the per-OSD object density but yes, I agree
that will hurt.

I doesn't seem like the problem here, but I've noticed that slow OSDs have
a large fan-out. I have less than 100 OSDs, so every OSD talks to every
other OSD in my cluster.
I was getting slow notices from all of my OSDs. Nothing jumped out, so I
started looking at disk write latency graphs. I

What was the osd_backfill_full_ratio? That's the config that controls
backfill_toofull. By default, it's 85%. The mon_osd_*_ratio affect the
ceph status.
I've noticed that it takes a while for backfilling to restart after
changing osd_backfill_full_ratio. Backfilling usually restarts for me
In this case the root cause was half denied reservations.

This stopped backfills since, those listed as backfilling were
actually half denied and doing nothing. The toofull status is not
checked until a free backfill slot happens, so everything was just
Hi John,
For the last part, there being two different versions of packages in
Giant, I don't think that's the actual problem.
What's really happening there is that python-ceph has been obsoleted
by other packages that are getting picked up by Yum. See the line
that says Package python-ceph is
Very very good :)
