[PVE-User] Scaling up Proxmox VE

[Alexandre DERUMIER]

corosync2 have a new feature:

dynamic token timeout

https://github.com/corosync/corosync/wiki/Corosync-2.3.4-Release-Notes

I think it could be usefull to scale up without too much tuning.

Hi Andrew, 

if you have more than 16 nodes it can happen, that the ring packet from corosync is to slow. 
therefore you cluster think the nodes are offline.

Hi, 

I notice the wiki mentions a soft-limit of 16 nodes. 

What happens beyond this ? 

We are already at 16 nodes, and looking to continue growing our cluster. 

What are other people doing to scale up ? 

We have considered multiple clusters, but there is currently no way to specify VMID ranges and UUID's are not used so we are concerned about getting overlapping VMID's on shared storage. 


Regards, 



Andrew
