Description Manjunatha 2020-06-18 06:57:40 UTC

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.

Comment 12 Mudit Agarwal 2020-09-21 05:41:18 UTC

Moving it to 4.7, we should already have an Epic for this and I guess the BZ can be closed.

Comment 16 Marc Schindler 2021-04-09 12:53:01 UTC

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:

Comment 21 Jilju Joy 2021-06-08 13:15:03 UTC

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
