So I'm in the process of converting every node in my cluster to ZFS (RAID1 - a single mirror zpool) (powered by OpenEBS's ZFS LocalPV for the k8s heads out there). I'm going to try running Ceph w/ bluestore but doing something that would normally make absolutely no sense -- disabling the checksumming features of Ceph.
Also just in case the above wasn't enough I'm probably actually going to run Longhorn because it's just SO much easier than Ceph to manage and gives me the availability for a ~40% perf loss AFAIK.
