Issue

While installing Red Hat OpenShift Data Foundation (ODF) or Red Hat OpenShift Container Storage using Red Hat Ceph Storage (RHCS) in external mode an erasure-coded pool was setup as the default data pool during the Ceph cluster creation. Noobaa will use RBD which by default does not work with erasure-code pools.

• erasure-coded pools by default do not support omap. To work for RBD or CephFS an additional parameter must be set (see resolution).

When trying to create the PVC for Noobaa it would hang in the pending state, with the following errors:
