Version-Release number of selected component (if applicable): openshift v3.5.5.24 Document URL: https://access.redhat.com/documentation/en-us/openshift_container_platform/3.5/html-single/installation_and_configuration/ Section Number and Name: 2.2.1.2 Minimum Hardware Requirements Describe the issue: While running OCP 3.5, one of the nodes hit the out of disk space condition. This condition caused the removal of the glusterfs pod on that node, which was running CNS. I was asked to expand the filesystem in order to remedy the out of space condition. This node was provisioned with 50G of space for the /var/ file system. After reviewing the OCP 3.5 documentation, I see that the minimum requirement for a node is that the file system that contains /var/ needs to have 15G of space. Given that the /var/log/journal directory on this node grew to ~33G (more than double the aforementioned requirement) is that minimum requirement still valid? Though it is possible to expand the file system, it can definitely be a pain point.
