[PVE-User] how many nodes can there be in a proxmox cluster ?

I'm running 20 nodes clusters here, with unicast. (I need to increase corosync timeout a little bit with more than 12 nodes). 

I think the hard limit is around 100nodes in last corosync, but recommendations is around 32. with more than that, I think the corosync timeout need to be increase high and you'll have latency.

once around proxmox 2 i read something about a hard limit about 32 
nodes, due to corosync limits. but that there should probably not be 
that many. 

i have not been able to find any more recent information. 

is there a hard or soft limit to how large a proxmox cluster you can 
have ? what is the largest installations people are running. and does 
this affect stabillity of the cluster? 

kind regards
