- Upgrade from Ceph Mimic to Ceph Luminous
In Lab11 we deployed Ceph Mimic (v13.2.5), we will upgrade to Ceph Nautilus.
To do that we need to change the image used by our Ceph cluster from image: ceph/ceph:v13.2.5-20190410
to image: ceph/ceph:v14.2.1-20190430
kubectl -n rook-ceph edit CephCluster rook-ceph
Then we can watch Rook work, wait until your cluster goes from Updating
to Created
state.
watch -n 1 -d kubectl -n rook-ceph get CephClusters,deployments,pods -o wide
Rook will upgrade Ceph mons one at a time, then Ceph mgrs, then Ceph OSDs.
Run a ceph status
in the toolbox to verify that the cluster is healthy and upgraded.
Congratulations you are done with the workshop.
