Is there a ISCSI problem for ubuntu os and Rancher if yes how can i solve this?

I am new to Rancher service and want to create openebs volumes for MySQL pods for that I created PV but the container is in initialization state but not active how can I accomplish this problem. I followed this blog

I’m not sure about CentOS but for Ubuntu on the nodes:

apt-get install open-iscsi
systemctl disable iscsid
systemctl disable open-iscsi

It keeps the kernel drivers but disables iscsi daemons so they don’t conflict with pods…
