Re: auth error with ceph-deploy on jewel to luminous upgrade

Sorry to reply to my own question, but I noticed that the cephx key for client.bootstrap-mgr was inconsistent with the key in /var/lib/ceph/bootstrap-mgr/ceph.keyring.

I deleted the entry in ceph:

    ceph auth del client.bootstrap-mgr

reran the ceph-deploy gather keys:

    ceph-deploy gatherkeys cephtest-admin

and used the key entry for client.bootstrap-mgr as the key value in /var/lib/ceph/bootstrap-mgr/ceph.keyring.

I was then able to successfully run the ceph-deploy to create the mgr.

I'm not sure where this inconsistent key came from as the /var/lib/ceph/bootstrap-mgr directory doesn't appear on a fresh install of jewel.

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-stor2:/var/lib/ceph/osd/ceph-1
ceph-deploy osd activate cephtest-stor1:/var/lib/ceph/osd/ceph-0
ceph-deploy osd activate cephtest-stor2:/var/lib/ceph/osd/ceph-1
ceph-deploy admin cephtest-admin
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
Gary

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