> will probably move to Ceph ... Every so often I look into btrfs/ZFS/mdadm, but keep reaching the same conclusion that it's just not worth the risk. The worst thing about my experiences with mdadm and ZFS is that I've had exactly one catastrophic failure in 15 years. The best thing about my experiences with Ceph is that it's really reinforced the importance of a good backup strategy. The combination of the two means I now run ZFS, and I have a comprehensive backup strategy that is regularly tested, but has never needed to be invoked. I strongly recommend developing a strong backup story before you go down your Ceph journey.
