Configuring Metrics Storage 2.6.3.12. Configuring Cluster Logging Describe the issue: References are made to [nfs] host group but it is never clearly explained. Suggestions for improvement: Add explanation of [OSEv3:children] section/group, the [nfs] section/group, and entries under [nfs] Additional information: Adding Persistent Volumes in a planning section would also help to organize this. It cost several weeks for us to find many of our issues were due to no PV's to match up with PVC's. Further, Examples for [nfs] are hard to find. Many of the example files are broken as delivered.
