Dear Cephers...
1./ I am currently deploying infernalis 9.2.0 in centos7.
2./ I am not using ceph-deploy (I prefer not to use it) and I prefer to
use the short form osd installation procedure described here:
http://docs.ceph.com/docs/infernalis/install/manual-deployment/#short-form
3./ In hammer this instructions worked fine but in infernalis 9.2.0,
which the implementation of the ceph user running the ceph daemons,
those instructions do not seem to work properly anymore.
4./ Here is the behaviour:
4.1/ ceph-disk prepare runs fine:
# ceph-disk prepare --cluster ceph --cluster-uuid
a9431bc6-3ee1-4b0a-8d21-0ad883a4d2ed --fs-type xfs /dev/sdh /dev/sdc3
WARNING:ceph-disk:OSD will not be hot-swappable if journal is not
the same device as the osd data
WARNING:ceph-disk:Journal /dev/sdc3 was not prepared with ceph-disk.

4.2/ ceph-disk activate fails with permission problems. It seems
some temporary directory us made by root which is then not accessible to
ceph user.
# ceph-disk activate /dev/sdh1

4.3 If I run the the ceph activate command as a ceph user, it
complains it need root permissions to mount
# su ceph -s /bin/bash --session-command="ceph-disk activate /dev/sdh1"
Problem opening /dev/sdh for reading! Error is 13.
You must run this program as root or use sudo!
mount: only root can use "--options" option

5./ So there is an incoherence on this set of instructions.
Is there a way to solve / patch that solves this?
Cheers
