Re: RHEL 7.1 ceph-disk failures creating OSD

It seems to be a RHEL licensing issue. We got RHEL partner licenses, but we’d have to pay for ceph repo access, but when I use the RHEL repos I can only get 80.7. It many hours to work through that and even get
 that to install so that I can get to the point that it fails to make the partition.

I’d rather go back to Centos.

Bruce - I ran in to problems w/ ceph-disk on same version too - then switched to Hammer (0.94) ... that worked for me.  I didn't track the issue down.  

Some reason you are deploying an older version ?

I have moved storage nodes to RHEL 7.1 and used the basic server install. 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.
