Description of problem (please be detailed as possible and provide log snippests): it is possible to create thick-provisioned RBD images. Under certain circumstances, we would like to be able to create this type of images directly from OCP. Version of all relevant components (if applicable): OCS 4.4 Is there any workaround available to the best of your knowledge? There are two different options: 1-Set this option in the storage class, thus all the subsequent images will be thick-provisioned. 2-Include an option in the PVC specifying that a thick-provisioned image is required.
Talking to Moran, I was reminded that VMs (CNV) might benefit from this.
Moving it to 4.7, we should already have an Epic for this and I guess the BZ can be closed.
Any update for this topic? IHAC (Lufthansa) who also need the function, because kafka write and delete a lot and workflow fstrim/mount option discard is currently not an option for his production environment. I can't find anything in OCS 4.6 release notes: https://docs.openshift.com/container-platform/4.7/release_notes/ocp-4-7-release-notes.html
Verified that RBD thick provisioning feature is enabled in OCS 4.8.0 To create RBD thick PVC, users can make use of the storage class ocs-storagecluster-ceph-rbd-thick or create a new storage class with thick provision enabled. Verified in version: OCS operator v4.8.0-408.ci Cluster Version 4.8.0-0.nightly-2021-06-03-160817
