Description Jan Safranek 2019-01-14 12:30:12 UTC 
Description of problem:
Dynamic provisioning of Ceph RBD volumes does not work in 4.0 because /bin/rbd is missing in controller-manager image.

Version-Release number of selected component (if applicable):
oc v4.0.0-alpha.0+2b41d8b-874-dirty [beta1-ish]

How reproducible:
always

Steps to Reproduce:
1. follow https://access.redhat.com/documentation/en-us/openshift_container_platform/3.11/html/configuring_clusters/persistent-storage-examples#install-config-storage-examples-ceph-example and set up Ceph RBD dynamic provisioning

2. Create PVC

Actual results:
  Warning    ProvisioningFailed  1s                 persistentvolume-controller  Failed to provision volume with StorageClass "dynamic": failed to create rbd image: executable file not found in $PATH, command output:
Mounted By:  <none>


Expected results:
PVC is provisioned

Additional info:
Provisioning starts to work after installing ceph-common to kube-controller-manager:

$ kubectl -n openshift-kube-controller-manager exec -ti openshift-kube-controller-manager-ip-10-0-45-117.eu-central-1.compute.internal  yum install ceph-common

Bump.
Comment 4 Jan Safranek 2019-04-09 07:28:30 UTC 
Raising priority, it blocks tests.

Comment 13 Eric Paris 2019-06-27 14:38:17 UTC 
At this time we only expect to support Ceph via CSI. Not via 'in-tree' or 'flex'. As such we do not plan to add these to RHCOS or inside the image.
