== 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 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.
