script cara untuk menambah disk router yang secara default kurang dari 100 MB

This script very depends on utils output and routeros partitions and etc, so it could probably fail in the future. But the main idea should be quite clear.
I prefer to use previous variant of this script because it runs quite faster. In fact, I do not know why you could ever need to have a big partition on router vm.

PS :
1. check your interface name before apply. here the interface name is : "ens3". Change according yours
2. CHR can run only in full virtualization like vmware, kvm, xen or hyper-v
