Hello Sanath, You could cleanup some space in the root partition, controller-0 can get back to ‘available’ state automatically. Yeah, cleaning up space is messy. We need to have the proper solution. Attached mail in regards to space consumed by tmpfs – wondering its allocation around 63GB & only 1% is used. Need to justify. Regards, Susendra.

As a reply to the previous meet, I am posting these screenshot and documentation which has information regarding the memory allocated to controller-0. Memory allocated to controller-0 was 20GB, and my machine has 2.2T of memory. And my question was, Is there any method where we can increase the controller-0 memory allocation. 2. Since the availability of controller-0 is degraded, Is there any way we make the availability of controller-0 available? Below are the links which have the information regarding controller-0 1. https://drive.google.com/file/d/1phZPTh3IlpoqRLJQJTJA2puJxTtHWai_/view 2. https://drive.google.com/file/d/1vHx-GZ5mxAbnAiegK8jl7GqnjtokmaWf/view Note: Virtual All-in-one Simplex Installation R4.0 Regards, Sanath Kumar +91 8971546076
