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.

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. Regards Karan Singh From: "alistair whittle" <alistair.whittle@xxxxxxxxxxxx> 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: [ceph_deploy.sudo_pushy][DEBUG ] will use a remote connection with sudo [ceph_deploy.osd][INFO ] Distro info: RedHatEnterpriseServer 6.4 Santiago [ceph_deploy.osd][DEBUG ] Deploying osd to ldtdsr02se19 [ldtdsr02se19][INFO ] write cluster configuration to /etc/ceph/{cluster}.conf [ldtdsr02se19][INFO ] keyring file does not exist, creating one at: /var/lib/ceph/bootstrap-osd/ceph.keyring [ldtdsr02se19][INFO ] create mon keyring file [ldtdsr02se19][INFO ] Running command: udevadm trigger --subsystem-match=block --action=""> [ceph_deploy.osd][DEBUG ] Preparing host ldtdsr02se19 disk /osd2 journal None activate False [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.

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?
