I need to have an iSCSI storage to be used by my oVirt lab. The last time I had to create an iSCSI target was during the preparation of the RHCE 7 exam. Therefore, I think this is an opportunity to practice doing this again. First, install the required package. Then enable the target service, otherwise the target won’t work on the next reboot. [root@utility ~]# dnf install targetcli -y [root@utility ~]# systemctl enable target Run the targetcli command to create an iSCSI target/storage using the storage block (/dev/mapper/data_iscsi LVM volume)....

This is my note about installing FreeIPA on a CentOS 8 machine. It’s a bit different from the FreeIPA’s installation on CentOS 7, and most importantly there was a problem I came across during the installation and how to fix it. Configure Static IP [root@utility ~]# nmcli con mod enp1s0 ipv4.addresses 172.25.250.8/24 \ > ipv4.method manual \ > ipv4.gateway 172.25.250.254 \ > ipv4.dns 172.25.252.1 \ > connection.autoconnect yes [root@utility ~]# nmcli con up enp1s0 Ensure the hostname of this server exists in /etc/hosts....

Today, one of my VMs needs to have its disk increased. I’m using qcow2 as the VM’s storage. Here is one way to expand the storage that it’s been proven to work very well for me. I already increased this VM’s disk to 30GiB once already, but it wasn’t enough. So here, let’s explode it to 50GiB. The name of the qcow2 file is hosta.qcow2. A friendly reminder that you should alway shave a backup before you perform any critical change such as this one....

One of the requirements to join an Identity Management Server (IdM) to an Active Directory (AD), a DNS delegation needs to be created on AD. With the Red Hat training for RH362, we were taught to use a command-line interface program called dnscmd on AD server. I personally found this command very cumbersome, and I think a better way is to do this DNS delegation using PowerShell cmdlet. I’ll demonstrate how to do DNS delegation both using dnscmd and PowerShell cmdlet....

Today I passed the Red Hat Identity Management exa, EX362, with the score of 233/300. The material used to prepare for the exam is the RH362 online course, provided Red Hat. At first I wasn’t sure if I should use of the 5 exam credits (as part of one-year training subscription), but it turned out that IdM/FreeIPA is useful and fun to learn. Here are some tips for this exam:...
