I have a Dell R730 server at work, which connects to a back-end storage with optical fiber cables. In addition, the server itself also has 6 disks. Two of the disks have already been configured as RAID1 and has the operating system installed on it. Today, I want to configure the remaining 4 disks as RAID10, and setup logical volume on it. The first part was easy. All I had to do was to login to the Integrated Dell Remote Access Controller (iDRAC), and create a new Virtual Disk from the 4 physical disks. The second part is a bit tricky. As the server is connected to the stroage server, it sees a lot of disks. ...

TLDR; just follow this guide. At home I run DHCP and DNS servers on Odroid U3, a system on a chip (SoC) computer. This allows me to have lots of control over my home network and most importantly – fun. I also run some web sites and Postgresql databases for testing purposes. The SoC computer runs Ubuntu 16.04 as the operating system. Recently, the Odroid U3 died. A coworker also has an SoC, an Odroid XU4. But, he found no use of it so I bought it off him at a very good price. This new SoC will replace the Odroid U3. ...

urxvt or unicode-rxvt is a terminal simulator like Gnome-terminal or Konsole. Recently I’m trying to switch to use i3 (i3-gaps), a tiling windows manager, and urxvt is good compliment to i3. Unlike Gnome-terminal or Konsole, the font name and size for urxvt are configured in ~/.Xresources. To make change to font size, for example, I’d edit ~/.Xresources, reload it with xrdb ~/.Xresources, and finally close and re-open urxvt itself. Though there is no built-in function to allow changing font size on the fly, urxvt allows us to do this via extensions. ...

My main machine at home has been upgraded from Fedora 26 to 27 since the day the 27 was released. Everything has been working great, except the ZFS file system. I’m a ZFS-believer and I store my important files on ZFS-based storage. For a while there was no repository for Fedora 27 provided by zfsonlinux, until 6 days ago. I have been using packages provided for Fedora 26 as work around solution. If you’ve been using the ZFS packages for Fedora 26, you can upgrade to the ones for Fedora 27 now. ...
