[ClusterLabs] If You Were Building a DRBD-Based Cluster Today...

[Eric Robinson]

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?
