Hi Larry,
As you suggested I have changed to Ubuntu 10.04. Still I could not able to
figure out what is this problem. I skipped only two sections in ceph
documentation is 1) SSL 2) DNS , as I thought not needed any security to my
gateway.
1) I strongly have a doubt in specifying hostname in ceph.
Thanks Sebastien.

Hello,
Most recently when looking at PG’s folder splitting, I found that there was
only one sub folder in the top 3 / 4 levels and start having 16 sub folders
starting from level 6, what is the design consideration behind this?
For example, if the PG root folder is ‘3.1905_head’, in the first le
Hi All,
Just wondering if there was a reason for no packages for Ubuntu Saucy in
http://ceph.com/packages/ceph-extras/debian/dists/. Could do with
upgrading to fix a few bugs but would hate to have to drop Ceph from
being handled through the package manager!
Thanks,

With the reweight-by-utilization applied, CRUSH is failing to generate
mappings of enough OSDs, so the system is falling back to keeping
around copies that already exist, even though they aren't located on
the correct CRUSH-mapped OSDs (since there aren't enough OSDs).
Are your OSDs correctly weigh

Okay, well, let's try and track some of these down. What's the content
of the "ceph.layout" xattr on the directory you're running this test
in? Can you verify that pool 0 is the data pool used by CephFS, and
that all reported slow ops are in that pool? Can you record the IO
patterns on an OSD while

The value can be set during the image creation.

Hi All,
I am using cinder as a front end for volume storage in Openstack
configuration.
Ceph is used as storage back-end.
Currently cinder uses only one pool (in my case pool name is "volumes" )
for its volume storage.
I want cinder to use multiple ceph pools for volume storage

To start over is easier to do it from scratch to avoid configuration

It has happened to me more than once :)
