[pve-devel] corosync unicast : does somebody use it in production with 10-16 nodes ?

[Alexandre DERUMIER]

note that I'm just seeing , time to time (around once by hour),

pvedaemon: ipcc_send_rec failed: Transport endpoint is not connected

But I don't have any corosync error / retransmit.

Objet: [pve-devel] corosync unicast : does somebody use it in production with 10-16 nodes ?

Hi, 

I'm looking to remove multicast from my network (Don't have too much time to explain, but we have multicast storm problem,because of igmp snooping bug) 

Does somebody running it with "big" clusters ? (10-16 nodes) 


I'm currently testing it with 9 nodes (1200vm+containers), I'm seeing around 3mbit/s of traffic on each node, 

and I don't have any cluster break for now. (Switch have recents asics with around 0,015ms latency). 


Any return of experience is welcome :) 

Thanks ! 

Alexandre
