Bug Description
Since the release of corosync 3.0 the default transport method is knet(2) and udp/udpu are still there only for backwards compatibility(3), and their maintenance is restricted to bugfixes(1).
Among the benefits of knet over udp I would highlight these three:
1: Better tolerance for small network outages(3).
- We've had some issues multiple times, and we had to lock our machines on MAAS in order to avoid hacluster+
2: Better performance and lower latencies(3).
3: Allow for multiple rings, up to 8(2-3), enables lp:1850822.
- This would allow to have ring0 on oam-space and ring1 on internal-space, which could help with those small network hiccups
