If you were building a DRBD-based cluster today on servers with internal storage, what would you use for a filesystem? To be more specific, the servers have 6 x 3.2 TB NVME drives and no RAID controller. Would you build an mdraid array as your drbd backing device? Maybe a ZFS RAIDZ? How would you feel about using ZFS as the filesystem over DRBD to take advantage of filesystem compression? Or would you do something else entirely?

What will the use-case be?
