Hi,
There's something I don't understand about the exclusive-lock feature.
I created an image:
$ ssh host-3
Container Linux by CoreOS stable (1298.6.0)
Update Strategy: No Reboots
host-3 ~ # uname -a

I don't know how radosgw objects are stored, but have you considered a
lower level rados export/import ?

Hi all,
I have weird behaviour on my firefly test + convenience storage
cluster. It consists of 2 nodes with a light imbalance in available space:
# idweighttype nameup/downreweight
-114.58root default
-28.19host store-1
12.73osd.1up

Thanks for the info! Great data points. We will still recommend a
separated solution, but it's good to know that some have tried to
unify compute and storage and have had some success.
Yes, and using drives on compute node for backup is a seducing idea

Thanks for your answers
u I have that for an apt-cache since more than 1 year now, never had
an issue. Of course, your question is not about having a krbd device
backing an OSD of the same cluster ;-)

Hello,
if you use kernel RBD, maybe your issue is linked to this one :

Hi,
I have a pretty big problem here... my OSDs are marked down (except one?!)
I have ceph ceph version 0.61.8 (a6fdcca3bddbc9f177e4e2bf0d9cdd85006b028b).
I recently had a full monitors so I had to remove them but it seemed to
work.

Yep! What distro is this?
I'm working on Gentoo packaging to get a full stack of ceph and openstack.
Overlay here:
git clone https://git.isi.nc/cloud/cloud-overlay.git
And a small fork of ceph-deploy to add gentoo support:
git clone
Hi lists,
in this release I see that the ceph command is not compatible with
python 3. The changes were not all trivial so I gave up, but for those
using gentoo, I made my ceph git repository available here with an
ebuild that forces the python version to 2.6 ou 2.7 :
git clone

both disks can be doing something completely different.
Completely agree, Ceph is already doing the stripping :)

you can try the RAM as a journal (well... not in production of course),

Hi Greg,
thank you for your (fast) answer.
Since we're going more in-depth, in must say :
* we're running 2 Gentoo GNU/Linux servers doing both storage and
virtualization (I know this is not recommended but we mostly have a
low load and virtually no writes outside of ceph)

Seems good : the load drop behind the 1.0 line, ceph starts to scrub,
the scrub is fast and load goes higher the 1.0, there's a pause
