Linbit push new features with DRBD on pve

Is DRBD 9 stable ?
3way replication would be, IMHO, one of the best replication system for HA clusters.
drbd is in kernel from many, many years and constantly developed.

better use DRBD than any $one-man project or with a dead community.
 
.... the devil is in details. Any real-time replication will add a degradation of performance. Many replicas = bad performance. I understand this after I see how it is percona-cluster. 3 nodes versus n nodes.
 
This is true, but i've tried some days ago LizardFS with 3 node replication on a simple gigabit network.
I'm able to push 100-110MB/s constantly when writing files. Writes are sync, not async. I don't see any performance drop, writing the same directly on disk I get about 100-120MB/s, the bottleneck are SATA disks (used as tests) and, obviously, the gigabit network.

Can you explain a little more? Do you have a step by step guide or some information on how to build that?
