Why would you use LVM with ZFS? ZFS should handle all of the features LVM has (as far as I can think of, at least).

- magicalhippo 3y agoThe idea would be to use LVM to get writeback caching on the block-device level, then use those cached LVM devices as backing devices for a ZFS pool. I've tested this on a small scale prototype level (one HDD and one NVME SSD) and there it worked quite well. But like I said it feels a bit fragile, lots of moving parts.
