We wanted to use external CephFS for Kubernetes but they want to One thing I really want to do is get a test with OpenEBS vs Rook vs vanilla Longhorn (as I mentioned, OpenEBS JIVA is actually longhorn), but from your testing it looks like Ceph via Rook is the best of the open source solutions (which would make sense, it's been around the longest and Ceph is a rock solid project). Rook provides a very clean method to directly deploy Ceph within Kubernetes clusters as well if you're installing bare metal. Both Quobyte and Ceph run on cost-effective commodity servers and have moved all fault-tolerance to the software layer, truly abstracting it from the hardware. kubernetes] key = AQDXs9JeQXtqFRAAGSU9alHjNm+CORLwBk9qQg Ceph is harder to maintain and it needs some top-level hardware (10Gbe+ nvme drives, which will degrade quickly).

Helm finds the Kubernetes cluster by reading from the local Kubernetes config file; make sure this is downloaded and accessible to the helm client. So yes you can use Proxmox and Ceph as parts of a NAS solution, along with SMB or NFS it whatever. On each worker node you need a free unmounted device used exclusively for ceph. Ceph is basically an object-oriented memory for unstructured data, whereas GlusterFS uses hierarchies of file system trees in block storage. They're currently deployed as a Proxmox cluster with Ceph storage. Helm can be installed by following these instructions. 22 through v1. Rook supports only Nautilus and newer releases of Ceph.
