Describe the issue: - Include a section for chrony as a Prerequisites for RHCS 5 installation Describe the task you were trying to accomplish: - Current RHCS 5 installation guide doesn't contain a section for time synchronization. For distributed storage, time synchronization is very important. So include a section for chrony as a Prerequisites for RHCS 5 installation. Suggestions for improvement: - Update the Prerequisites section of RHCS 5(Chapter 2. Red Hat Ceph Storage considerations and recommendations). Document URL: https://access.redhat.com/documentation/en-us/red_hat_ceph_storage/5/html-single/installation_guide/index#prerequisites Chapter/Section Number and Title: 2.1. Prerequisites Product Version: RHCS 5 Any other versions of this document that also needs this update: NA
