Not sure at what stage/node you see this..but can you first double check you connections/ips/subnets not overlapping one another.

on new instalation cannot create new cluster,There is no problem in installing 2.8.1 and 3.0.1. When installing 3.0.2, after entering the cluster name and password, click Next and it will appear

What are the values of MD5 and SHA-256 of 3.0.2, is there something wrong with my download?

Please double check your network connections/ips/make sure no duplicate ips, no overlap of subnets..etc.

Then re-install from iso from the beginning. Then deploy the nodes one by one, if you get an error while deploying..stop and post the  PetaSAN.log file for that node and state which node number it is.
