Internal Server Error - issue when deploying erpnext in kubernetes

ERPNext
, ,
1

I have deployed erpnext following guidelines about deploying erpnext in Kubernetes, (‘frappe/erpnext:v15.11.0’)
all pods are running fine but when i browse the hostname which is the same as my site name I get Internal Server Error.
I have two volumes mounted in all pods
/home/frappe/frappe-bench/sites
/home/frappe/frappe-bench/logs

after looking at erpnext-gunicorn pod logs below is the error

Volume must be RWX and allow symlink.

For CRI-O refer assets are not properly mounted when using CRI-O as container engine · Issue #181 · frappe/helm · GitHub

I have tried the entrypoint script which creates the asset folder in site’s directory with symlink to frappe and erpnext public folders from the bench root directory. but i am still getting the same issue. I am using Openshift .
