The GPU Kubernetes cluster will undergo a major update in October.
TL;DR: a complete cluster reinstallation will be necessary due to major changes in the underlying network hardware. New persistent storage will be installed, and all persistent volumes will need to be deleted, as the drives will be integrated into the new system. Please start to backup everything and be prepared to stop all pods and delete your PVs on short notice.
Some details in using the cluster after the reinstallation will change slightly. Some of them you can test already, please do so and help me find possible bugs before all changes go live. See below for details.
