So, I've recently completed the RHCSA and RHCE exams successfully and I wanted to share my experience with it. Here are a few of my thoughts about both exams. Time: There's plenty of it on RHCSA but not so much on RHCE. If you know what you are doing on the topics, you'll be done in under 1 hour (in case of the RHCSA) assuming you are decently fast in typing. However, that's not the case with RHCE. For passing RHCE, you'll need to have good time management and eventually skip tasks that you get stuck on since you might not be completing the rest of the tasks. Tasks: Take a minute and read through all the tasks first. Map your own 'Big Picture' on how the system has to look like in the end. This includes the configuration of SELinux, Firewalld and systemctl. Note that your changes and configurations have to be persistent between reboots. If you can do the labs without too much of a hassle, you should be good to go. What you want to avoid however is ...

While I was practicing for RHCSA, I noticed, that for me, the automount part is the most difficult. For making this thing more memorable, I decided to write a short guide to what I did to get this working and share my knowledge. Maybe this will actually help someone understanding it :) I'll work with two nodes, nfssrv.archyslife.lan and nfsclnt.archyslife.lan. The names are kind of obvious what the servers will do. First, let's set up the server which will share it's files: [root@nfssrv ~]# yum -y install nfs-utils [root@nfssrv ~]# vim /etc/exports /storage 172.31.100.0/24 (rw,secure,sync,no_subtree_check) [root@nfssrv ~]# mkdir /storage [root@nfssrv ~]# systemctl enable nfs.service [root@nfssrv ~]# systemctl start nfs.service This set of commands will install the nfs-server software, configure your /storage directory to be shared using nfs to the network 172.31.100.0/24 and start the nfs-service on boot. Now the client-side: ...
