Hello, I am thinking about RAFT HA setup and I would like to have two separate networks for cluster sync. Like corosync can have multiple rings, which I effectively use.
Somebody can suggest use of LAG, but also if LAG is created on switch stack connected each to different physical switch them there is problem about whole stack reboot/unavailability… (fw upgrade, mgnt move, topology change, some bug in sw, etc…). So I use two rings in corosync, one primary to separate switch and second one as backup via LAG to switch stack.
Is there any way to use two networks in frontend HA setup using RAFT?
