Thanks Alexandre!! We plan to proceed as follows for upgrading infernalis to jewel: Enable Repo on all Nodes #cat /etc/apt/sources.list.d/ceph_com_jewel.list deb http://download.ceph.com/debian-jewel trusty main For all Monitors (one after the other) 1) sudo apt-get update && sudo apt-get install ceph-common 2) service ceph stop 3) service ceph start For all OSDs (one after the other) 1) sudo apt-get update && sudo apt-get install ceph-common 2) service ceph stop 3) service ceph start based on the documentation there are no "release specific" procedures for upgrading infernalis to jewel http://docs.ceph.com/docs/jewel/install/upgrading-ceph/ Other opinions/Recommendations are very welcome! Is it really that simple and unproblematic ??
