I'm looking for the future (1-2year), to manage big proxmox clusters
Currently I manage multiple cluster with max 16nodes, because corosync &&
multicast can be very difficult to tune.
(I'm also managing clusters across datacenters).
It's become to be difficult to manage, as we can't easily migrate vm across
clusters + we need to connect to differents cluster to manage vms.
I'm not an expert in cluster messaging, but I have found some projects which
a decentralized cluster messenging , based on gossip protocol
cluster messenging (it's use serf) + distributed key-value store + service
(some beta fuse-fs implementation exist too)
I don't known how much it could be to switch from corosync, pxmcfs,.... ?
Maybe something like serf is enough to replace corosync (an keep pmxcfs,ha
consul looks like corosync+ pmxcfs + ha services management.
So,It's just an idea, but I think getting rid of multicast/corosync could be a
great step for proxmox.
