Hi, Prior to firefly v0.80.8 ceph-disk zap did not call partprobe and that was causing the kind of problems you're experiencing. It was fixed by https://github.com/ceph/ceph/commit/e70a81464b906b9a304c29f474e6726762b63a7c and is described in more details at http://tracker.ceph.com/issues/9665. Rebooting the machine ensures the partition table is up to date and that's what you probably want to do after that kind of failure. You can however avoid the failure by running: * ceph-disk zap * partproble * ceph-disk prepare Cheers P.S. The "partx: /dev/disk/by-id/wwn-0x500003959ba80a4e: error adding partition 1" can be ignored, it does not actually matter. A message was added later to avoid confusion with a real error. .

I installed ceph-deploy and used the ceph.repo/epel.repo for installation of ceph 80.7. I have tried ceph-disk with issuing “zap” on the same command line as “prepare” and on a separate command line immediately before the ceph-disk prepare. I consistently run into the partition errors and am unable to create OSD’s on RHEL 7.1. > > > > ceph-disk prepare --cluster ceph --cluster-uuid 373a09f7-2070-4d20-8504-c8653fb6db80 --fs-type xfs --zap-disk /dev/disk/by-id/wwn-0x500003959ba80a4e /dev/disk/by-id/wwn-0x500080d9101001d6-part1 > > Caution: invalid backup GPT header, but valid main header; regenerating > > backup header from main header. > > > > **************************************************************************** > > Caution: Found protective or hybrid MBR and corrupt GPT.
