I'm running into a permission error when attempting to use
ceph-deploy to create an mgr on a recently upgraded
jewel->luminous ceph cluster. I've attempted to track down the
permission, but so far no success. I'm doing this on a dev
environment so I can replicate:
Start with a sample jewel release (one admin node with mon, two
storage nodes with one osd each). ceph preflight complete
(cephinst user with sudo, ntp, etc):
On each storage node, the osd disk is formatted as xfs and
mounted on /var/lib/ceph/osd/ceph-X, and "chown ceph:ceph
/var/lib/ceph/osd/ceph-X"
On admin server:
su cephinst
mkdir sci-cluster
cd sci-cluster
ceph-deploy
new cephtest-admin
ceph-deploy install cephtest-admin
cephtest-stor1 cephtest-stor2
ceph-deploy mon create-initial
ceph-deploy osd prepare cephtest-stor1:/var/lib/ceph/osd/ceph-0
ceph-deploy osd prepare cephtest-stor1
ceph-deploy
osd activate cephtest-stor10
ceph-deploy osd activate cephtest-stor1
cephtest-stor1
cephtest-stor2
ceph
osd pool set rbd size 2
sudo chmod a+r /etc/ceph/ceph.client.admin.keyring
At this point I have a working, healthy jewel cluster as
reported by "ceph -s". I then upgrade the mon and try to deploy
an mgr service:
sudo sed -i 's/jewel/luminous/g' /etc/yum.repos.d/ceph-deploy.repo
sudo
sed -i 's/jewel/luminous/g' /etc/yum.repos.d/ceph.repo
sudo systemctl stop ceph-mon@cephtest-admin.service
sudo yum clean all
sudo yum update
sudo systemctl start
ceph-mon@cephtest-admin.service
"ceph -s" reports HEALTH_OK, but "mgr: no daemons active".
Attempt to deploy a mgr service with ceph-deploy and it fails:

It looks like cephx was set up properly:

Any insight or hints would be appreciated.
Thanks

PS. on a previous attempt I did upgrade the ceph versions on the
osds as well before attempting to deploy the mgr; same result.
