storageClass not functional on regioCloud, cinder vol type wrong

[curx]

During investigation, we found the storage class on RegioCloud seems broken. The cinder volume type no longer exists or was replaced and the configuration is not synced to Kubernetes/Gardener.

Add. tech. notes:

for the Migitation, create a kubernetes storageClass with the current OpenStack cinder volume type and use the fixed one.

Please use this as workaround for the moment. We are adding a new NVMe SSD storage pool to REGIO.cloud at the moment and we already changed the storage types to the new names (hdd + ssd) on the Okeanos environment. At the moment the new storage types are not yet visible on your customer domain. I think the new pool will be ready for use next week.

Any updates about the new pool?

Seems the new storageClass setup is done, closed
