In the https://docs.onap.org/en/latest/submodules/oom.git/docs/oom_cloud_setup_guide.html#cloud-setup-guide-label it recommends 160GB for NFS but in reality this is too small.

During testing the Bulk PM Use case it was observed that the retention time on both Kibana logs (when debug is enabled) and Message Router topics (7 day retention by default) caused the disk to fill up quite quickly.

This can be mitigated by reducing the retention time at run time but ideally this could be avoided.  Also, the potential for data loss is still present.
