Hi Kevin -
We've decided to remove ceph-deploy and pushy from the ceph-extras repo to
reduce the confusion from having the packages in multiple places. That repo
has now been rebuilt without the packages.
The primary location for the ceph-deploy packages is the repo for the current
stable re

Hello all,
I am trying to install a ceph environment for testing, focused on block
devices for virtualization and object storage. I am facing some issues.
My environment consists of one server running ceph-deploy and mon; 3
cluster nodes with 3 disks each running a total of 3 OSD's; and one

PGs compared to the other. Since this is just for learning/testing I would like

Sorry, my bad. Only my second post and forgot the "reply all"
Thanks for the info. I'm looking at the impact of pg number on performance.
Just trying to learn more about how Ceph works.
I didn't set pgp_num. It came by default with 2 in my case.
Have a nice day,

You don't really want to — read-from-replica isn't safe except in very
specific circumstances.

Read-from-replica does not happen unless you go through some contortions
with config and developer setups. However, all n OSDs should be the primary
for about 1/n% of the data, so you should be seeing reads to to both OSDs
as long as you touch several objects at a time.

Hi !
I need a little help understanding reads from replicas. I've read a few
conflicting messages and the documentation is not very clear to me on this
subject (maybe I didn't find the proper doc).
Here's the question: With default replication of 2 (size=2), when doing reads

We have another bugfix update for bobtail. Most of these fixes have been

Hi Kevin -
it looks like something might be corrupted in ceph-extras repo. ceph-deploy
is also in the rpm-dumpling repo and that's the one we tested against.
http://ceph.com/rpm-dumpling/fc18/noarch/ceph-deploy-1.2.2-0.noarch.rpm
http://ceph.com/rpm-dumpling/fc18/noarch/pushy-0.5.3-1.noarch.
Also, when I download that package from the repo
(http://ceph.com/packages/ceph-extras/rpm/fedora19/noarch/ceph-deploy-1.2.2-0.noarch.rpm),
I get this:
$ rpm -q --requires -p ceph-deploy-1.2.2-0.noarch.rpm

Thanks for the response Gary. I'm still having a problem updating off the

I am trying to install CEPH and I get the following error -

Yes I read that but I was not sure if installing from Centos 6 repository can
cause issues.

Weird. I'm using 3.10.0 without issue here. What's the issue you're hitting ?
