I have a somewhat interesting scenario. I have an RBD of 17TB formatted using
XFS. I would like it accessible from two different hosts, one mapped/mounted
read-only, and one mapped/mounted as read-write. Both are shared using Samba
4.x. One Samba server gives read-only access to the world
CephFS, yes, but it's not considered production-ready.
You can also use an RBD volume and place OCFS2 on it and share it that way, too.

Hello,
This is my first real issue since running Ceph for several months. Here's the
situation:
I've been running an Emperor cluster for several months. All was good. I
decided to upgrade since I'm running Ubuntu 13.10 and 0.72.2. I decided to
first upgrade Ceph to 0.80.4, which was the
The other thing to note, too, is that it appears you're trying to decrease the
PG/PGP_num parameters, which is not supported. In order to decrease those
settings, you'll need to delete and recreate the pools. All new pools created
will use the settings defined in the ceph.conf file.
The underlying file system on the RBD needs to be a clustered file system, like
OCFS2, GFS2, etc., and a cluster between the two, or more, iSCSI target servers
needs to be created to manage the clustered file system.

The formula was designed to be used on a per-pool basis. Having said that,
though, when looking at the number of PG's from a system-wide perspective, one
does not want too many total PG's. So, it's a balancing act, and it has been
suggested that it's better to have slightly more PG's than you
Do you have all of the cluster IP's defined in the host file on each OSD
server? As I understand it, the mon's do not use a cluster network, only the
OSD servers.

I believe any kernel greater than 3.9 supports format 2 RBD's. I'm sure
someone will correct me if this is a misstatement.

Take a look at ProxmoxVE. Has full support for Ceph, is supported, and uses
KVM/QEMU.

There was a very recent thread discussing PG calculations, and it made me doubt
my cluster setup. So, Inktank, please provide some clarification.
I followed the documentation, and interpreted that documentation to mean that
PG and PGP calculation was based upon a per-pool calculation. The

The bug tracker says this was resolved ten days ago. Also, I actually used
ceph-deploy on 2/12/2014 to add two monitors to my cluster, and it worked, and
the documentation says it can be done. However, I believe that I added the new

Just for clarity since I didn't see it explained, but how are you accessing
Ceph using ESXI? Is it via iscsi or NFS? Thanks.

Correct me if I'm wrong, I'm new to this, but I think the distinction between
the two methods is that using 'qemu-img create -f rbd' creates an RBD for
either a VM to boot from, or for mounting within a VM. Whereas, the OP wants a

Instead of using ext4 for the file system, you need to use a clustered file
system on the RBD device.
