== Preview: changes in persistent volumes ==
All local NVMe and SSD drives will be integrated into the ceph storage cluster. The nodes will not provide local PVs anymore, and there is only one cluster-wide global storage class. You will finally be able to mount PVs read/write on different pods across different nodes. Special read-only storage for shared datasets will be provided as before, but driven by ceph instead of a an NFS export.
What you can do right now already to get rid of probably most of the data on your PVs is to move all static datasets to the system-wide storage, as described [[CCU:Global dataset storage|here]]. This framework will persist over the cluster reinstall and no data will be lost.
