Description Warren 2016-03-30 17:35:38 UTC 
Description of problem:
I need to manually start OSDs after installation to bring a cluster up

Version-Release number of selected component (if applicable):
RHEL 7.1, Ceph 1.3

How reproducible:
100% of the time.

Steps to Reproduce:
Bring up a ceph cluster using ceph-deploy
run ceph osd tree after adding the OSDs

Actual results:
All the OSDs are marked down

Expected results:
OSDs should not be down.

Additional info:
Run:
sudo service ceph -a start osd
after that and the cluster comes up fine.

This may also be the problem seen in 1320574
Comment 3 Warren 2016-03-31 00:17:38 UTC 
Upon further review, the following does not seem to start an osd:

ceph-deploy disk zap magna037:sdb
ceph-deploy osd create magna037:sdb

But the following does start the osd:

ceph-deploy disk zap magna037:sdb
ceph-deploy osd prepare magna037:sdb
ceph-deploy osd activate magna037:sdb1:sdb2
Comment 4 Kefu Chai 2016-03-31 12:09:02 UTC 
it sounds like an issue in ceph-deploy.
Comment 5 Alfredo Deza 2016-04-01 16:18:51 UTC 
@Warren, I think the ceph-deploy behavior on 7.N is expected. "create" is not used and "prepare + activate" is what our docs say:

https://access.redhat.com/documentation/en/red-hat-ceph-storage/version-1.2.3/red-hat-ceph-storage-123-installation-guide-for-rhel-x86-64/

Warren, 

Do Alfredo's suggestions in https://bugzilla.redhat.com/show_bug.cgi?id=1322551#c5 resolve your issue?
Comment 8 Warren 2016-05-23 16:52:06 UTC 
The prepare and activate combination works.
