Describe the issue: 1) 2.1. Ceph process management -> Additional Resources section rhel-8 needs to be changed to rhel-9 and thus links to rhel guides 2) 2.2. Starting, stopping, and restarting all Ceph daemons this subsection title needs to be changed to highlight that this subsection explains usage of systemctl only. ceph orchestrator has its own set of commands to manage ceph daemons >> orch daemon start|stop|restart|reconfig <name> 3) 2.4. Viewing log files of Ceph daemons that run in containers In step 1 the workd EXAMPLE is missing before example. 4) 3.1.1. Using the Ceph command interface interactively This section completely looks outdated by at least 2 major releases. Please contact cephadm smes to reform/remove this subsection which is not at all making sense while we have cephadm shell utility. 5) 3.1.2. Checking the storage cluster health The list of elements in Step 3 can be updated, cluster status displayed i) io: client: 853 KiB/s rd, 788 KiB/s wr, 858 op/s rd, 787 op/s wr ii) progress: Upgrade to 17.2.5-63.el9cp (25s) [............................] (remaining: 13m) 6) 3.1.2. Checking the storage cluster health and 3.1.7. Checking the storage cluster status seem highly overlapping and duplicate can be merged. 7) 3.1.9. Using the Ceph administration socket Step 4 commands seemed not working tried for a mon http://pastebin.test.redhat.com/1089477 Can it please be checked again ? 8) 5.2.6. Print a Ceph user key step 2 is actually just extended information after step 1, the intended procedure is not related. 9) 6.2. Why does ceph-volume replace ceph-disk? Below sentence seems to be false. ceph-disk was depricated in rhcs 4 Starting with Red Hat Ceph Storage 6, ceph-disk is replaced by the ceph-volume utility that aims to be a single purpose command-line tool to deploy logical volumes as OSDs, while maintaining a similar API to ceph-disk when preparing, activating, and creating OSDs. 10) 7.3. Benchmarking Ceph block performance First 6 steps seem redundant. can be removed upon discussion with rbd dev team.
