I see but just to be exact I may need to access the objects in the OSDs and try
to move it maniually !!
still can do that without RESTful gateway ??
Thank you.

Hi,
I've a question on cluster-network documented here:
http://ceph.com/docs/master/rados/configuration/network-config-ref/
In the docs we learn for the cluster network directive:
The IP address and netmask of the cluster (back-side) network (e.g.,
10.20.30.41/24). Set in [global]. You may specif
Hi Guys,
I am configuring CEPH and planning to use just one account for our app. One
schemer will map to one bucket, but before I do this, I need the answer of
following
questions:
1) can the number of buckets/account be set to unlimited or a very high number
which is practically not possible

Hi All,
I was running some experiments on my 3-node ceph cluster (mounted at
/mnt/ceph), and noticed unexpected behavior regarding cephfs set_layout
command.
root@varunc-virtual-machine:/mnt/ceph/folder1# touch test3
root@varunc-virtual-machine:/mnt/ceph/folder1# cephfs test3 set_layout -p 3

Hey folks,
I'm wondering if the following is possible. I have OpenStack (Folsom)
configured to boot VMs from volume using Ceph as a backend for Cinder and
Glance. My setup pretty much follows the Ceph guides for this verbatim.
I've been using this setup for a while now, and it's all been really
Hey all,
Just wanted to link to a few words on the new Ceph release cadence.

Travis,
The root disk (/var/lib/nova/instances) must be on shared storage to
run the live migrate. You should be able to run block migration (which
is a different form of the live-migration) that does not require shared
storage.
Take a look at:

Ubuntu 13.04 will be using a 3.8 kernel. Do you guys think that btrfs is
production ready for Ceph in linux 3.8? or would it be safer to use Ubuntu
12.04 and upgrade the kernel to 3.8? or even stick with XFS. Thanks.

I would argue that it is on shared storage. It is an RBD stored in Ceph,
and that's available at each host via librbd.

Thanks for the info. So if I want to do live migration with VMs that were
launched with boot-from-volume, I'll need to use virsh to do the migration,

A follow-up question. How do I cleanup the written data, after I finish up
with my benchmarks? I notice there is a cleanup object command,
though I'm unclear on how to use it.

It's pretty straightforward, but you can 'simply' delete the pool :)
(since it should be a test pool ;)).

I would either make my own pool and delete it when done:
rados mkpool testpool
RUN BENCHMARKS
rados rmpool testpool testpool --yes-i-really-really-mean-it
or use the cleanup command, but I ended up having to also delete
benchmark_last_metadata
RUN BENCHMARKS
rados -p data ls

Waed,
Ceph will rebalance automatically. Once you have completed the 5-minute
quick start guide, you can store an object with the rados command line and
see where Ceph's CRUSH algorithm placed your data.
Follow the instructions in this section:
