Thanks. It does seem to be working ok and I can create / remove objects it seems without issues.
I am however having another problem. In trying to add additional monitors to my cluster I am getting the following errors (note I did not see this when doing the first and currently only running monitor). It seems to set it up fine, but then has problems starting it.

Hello Alistar
I also faced exactly same issue with one of my OSD , after OSD Activate , progress got hanged but finally OSD gets added in cluster with no problem.
My cluster is running without knows issues as of now. If this is a test setup , you can ignore this , but keep an eye on this.

Subject: OSD activation issue
Hello all,
I am getting some issues when activating OSD’s on my Red Hat 6.4 Ceph cluster. I am using the quick start mechanism so mounted a new xfs filesystem and ran the “osd prepare” command.
The prepare seemed to be successful as per the log output below:
[ceph_deploy.cli][INFO ] Invoked (1.2.7): /usr/bin/ceph-deploy osd prepare ldtdsr02se19:/osd2
[ceph_deploy.osd][DEBUG ] Preparing cluster ceph disks ldtdsr02se19:/osd2:

[ldtdsr02se19][INFO ] Running command: ceph-disk-prepare --fs-type xfs --cluster ceph -- /osd2
[ceph_deploy.osd][DEBUG ] Host ldtdsr02se19 is now ready for osd use.
When I ran the activate, however, I got the following:
[ceph_deploy.sudo_pushy][DEBUG ] will use a remote connection with sudo

At this point, ceph-deploy just hung. After waiting for many minutes, I had to kill it manually. Looking at the OSD directory though, there is a lot of information that has been added there and when I do a “ceph health” it comes back as “HEALTH_OK”.
Is it really OK?
Thanks
