End of last year I have replaced my aging ASUS Zenbook UX32LN with a Ryzen-based UM431DA. After installing Ubuntu 20.04 focal with kernel 5.4 I have noticed four annoying problems:
- Initializing X.Org and getting to the login screen may not work
- Suspend does not work (system freezes)
- There is disturbing tearing when moving windows or playing movies
- Sound is very loud and volume control does not work properly
On Ubuntu and derivatives, there are multiple ways how ZFS volumes can be hidden from the volume listing in Nautilus (GNOME) or Caja (MATE). It is possible to hide individual volumes by editing /etc/fstab or blacklisting all volumes in the udev rules configuration.
After many successful years developing mfsBSD for FreeBSD systems I started to work on a small memory-only diskless distribution for Linux. It comes in handy if you want to run a diskless system, have a recovery partition with a rescue system or simply want to modify your primary hard drive layout.
RHEL and CentOS ship bootable CDs or DVDs in the ISO file format. It is possible to modify these ISO files with various types of customizations, e.g by adding additional boot menu items or an automated kickstart installation. This article contains a step-by-step guide how to customize and repackage a bootable CentOS ISO.
With the introduction of ZFS feature flags many users have experienced compatibility problems working with ZFS pools on different operating systems or operating system versions. In this article I am providing a table comparing the ZFS Feature Flag support on FreeBSD, Linux (zfsonlinux), Mac OSX (OpenZFS OSX) and illumos (OmniOS). Continue reading
In my past article “Tutorial: native ZFS on Ubuntu and Fedora Linux” I have given a tutorial how to install ZFS on Linux from the KQ Infotech github repository. This tutorial can be considered obsolete as the company KQ Infotech has been acquired by STEC, Inc (company with focus on SSD). Their ZFS on Linux project was assumably closed, as there is no more serious activity at their github repository. Continue reading
ZFS is a great filesystem and making it available for Linux opens a bridge between Solaris, FreeBSD and Linux.
KQ Infotech has released the source of their ZFS port to the general public, using pool version 28.
You can get more information at their webpage: kqstor.com
Source code is available at github.com.
In this arcicle I am giving a tutorial how to build from source and install packages of native ZFS kernel modules for Ubuntu/Debian and Fedora Linux.
You need a x86_64 version (64-bit) of the Linux distributions.
