Linbit push new features with DRBD on pve

[udo]

Hi,
just found this on twitter: https://twitter.com/philipp_reisner/status/913000348490588160
#LINBIT updated #DRBD integration to #Proxmox VE. Featuring: Proxmox-5, resizing, taking snapshots.

I would give DRBD an new try on my home-cluster...

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?

I've seen the documentation but found nothing regarding proxmox directly, only installing the client. Did you found any guide to deploy specifically on proxmox?

Thanks
