Thanks Roland,
I am not sure if I should start a new topic for this, but now you have me
wondering....
I use a classic 3 node setup, LVM backing devices, and a stacked third node
for DR using Protocol A. I have a VPN between the main site and off-site
and the latency hovers around 10ms.
Are there compelling reasons for me to look into DRBD 9? My current setup
is pretty solid, so far I have never needed to use the off site copies
(touch wood). I have 12 resources (all KVM HA servers) piped through the
VPN.
When your setup is more or less static and you have 2 nodes (or 3 with
stacking + proxy), using DRBD8.4 is IMO perfectly fine.
Not every setup is OpenStack/OpenNebula/... with > 1000 resources.
