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

THanks Srinivasa. The instruction is not for Ubuntu but I ll take it as

I actually found the problem is due to the public IP setting in ceph.conf

Hi all,
I'm new with Ceph and I would like to know if there is any way of
changing size of Ceph's internal objects.
I mean, when I put an image on RBD for exemple, I can see this:
rbd -p CephTest info base-127-disk-1
rbd image 'base-127-disk-1':
size 32768 MB in 8192 objects
order 22 (40
Hi,
The value can be set during the image creation.
Start with this: http://ceph.com/docs/master/man/8/rbd/#striping

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

Greetings,
I've been running dumpling for several months and it seems very stable.
I'm about to spin up a new ceph environment. Would I be advised to
install emperor? Or, since dumpling is solid, just stick with it?
Thanks much,

But, while updating, some nodes will run on older version for a some period. Is
this ok?

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).

Just wondering if there was a reason for no packages for Ubuntu Saucy in

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.
