change subnet mask on proxmox host, is it safe?

[ilia987]

is it safe to change (extend) the subnet mask for active proxmox servers ?
is there any precautions i should take ?

 

[apoc]

Is it a cluster? -> I would schedule maintenance
Is it a single host configuration? - I wouldn't mind

yes a working cluster of 10 nodes, i gave some certification on the question on the first post, (change subnet mask)

If the cluster can't communicate properly it might behave erratic.
From my perspective it is that simple. So the question can't be answered generic IMHO.
