My Canon and Nikon cameras use either the exFAT file system or the (older) FAT file system for image storage on their SD, SDxx, CF, CFexpress or XQD cards. In theory, the exFAT file system supports accurate time stamps up to a precision of 10 milliseconds. The FAT32 file system, in contrast, just offers 2 second accuracy for the modification time, or 10 millisecond for the creation time.Continue reading “Camera Manufacturers: Please Use Accurate Time Stamps for Image Files”
Linux kernel release 5.15 introduced a new NTFS file system driver named NTFS3. This kernel driver was originally developed by Paragon Software as a commercial solution (more about the ntfs3 driver can be found on their FAQ page).
NTFS3 is not to be confused with NTFS-3G, a user space driver that employs the FUSE or “file system in user space” approach. There is a 3rd driver available – simply NTFS – that was shipped as the standard NTFS driver on Linux, but it lacked support for many of the Microsoft NTFS features (like writing to disk). Most of us dealing with NTFS drives have installed and use the NTFS-3G driver.Continue reading “New NTFS Driver in Kernel 5.15”
Anyone who follows this website will notice that the tutorials are rather long. In these long tutorials I usually give reference specs, explain basic terms or processes, and expand on the how and why.
I wish I could write short, easy, step by step tutorials titled “GPU passthrough made easy” or the “Quick guide to VFIO bliss”. In fact, there are plenty of those out there in the great Internet. Some of the most popular ones are on Youtube, showing you how to get your Windows gaming VM up and running in no time.Continue reading “Why Long Tutorials?”
I was so busy studying, writing, and processing photos that I didn’t touch my Manjaro Linux host for a long long time. Then one day I decided to upgrade my PC from a 5.4 kernel to the most recent LTS or “Long Term Support” Manjaro Linux kernel 5.10.Continue reading “Manjaro Linux Kernel 5.10”
A look at Manjaro Linux from a VFIO passthrough user perspective – the benefits and downsides of using Manjaro as a Linux host
Last year in April I switched from Linux Mint via a short detour to Pop_OS to Manjaro Linux as my host OS. The reasons I chose Manjaro Linux were its up-to-date kernel and software and its well-rounded selection of software packages. However, the latest and greatest kernel and software can come at a price of being less stable. In this post I like to weigh in the pros and cons for Manjaro Linux and what you might want to consider before jumping on the wagon.Continue reading “Manjaro Linux”
Online data relocation to other drives using LVM and pvmove
These days my disks are filling up fast. My current PC holds 7 drives, including 2 NVMe drives. Actually 8 drives as I installed a new HDD today. All of my disks and partitions – with the notable exception of the FAT16 EFI partition for UEFI boot – are using LVM, the Logical Volume Manager.
With the availability of larger drives at reasonable costs, I decided to move some logical volumes (LV) spanning several drives onto one single drive, thus consolidating disks. This one drive will then be mirrored in a RAID-1 configuration for redundancy.
Note: In a multi-drive LVM Logical Volume each drive represents a potential point of failure. Moving the data from multiple drives onto one drive reduces that risk.Continue reading “LVM and the Ease of Migrating to a New Drive”
Tutorial for passing through a Nvidia RTX graphics card to a Windows 10 virtual machine using a modified VBIOS
Last update: September 14, 2021
Starting with the GeForce 1000 series, vfio passthrough of a Nvidia GPU has become a little more complicated. If, when starting the VM, you get a black screen, chances are you need to pass along a VBIOS file to the VM so the GPU can properly initialize.
This post is about passing through a Nvidia RTX 2070 Super GPU or any other modern Nvidia GPU to a Windows 10 guest.Continue reading “Passing Through a Nvidia RTX 2070 Super GPU”
Up until November 18, 2020 I would have suggested against the purchase of an AMD GPU for VFIO. But yesterday AMD launched its Radeon RX 6800 line of GPUs. Are the AMD Radeon 6800/6800XT suitable for VFIO?Continue reading “AMD Radeon 6800/6800XT for VFIO?”
Linux bash script to mount and backup / synchronize a Windows 10 partition inside a LVM volume to a remote backup server using rsync and SSH
I run the bash script below to backup my Windows NTFS partitions residing on LVM volumes to a remote backup server. It uses SSH and public key authentication to authenticate at the remote side.
The script mounts an NTFS partition inside a LVM raw volume. It performs a file-based backup using rsync. It is NOT suitable for system backups!
Please carefully read the “Requirements”, “How it Works”, and “Usage” sections before attempting to use it.Continue reading “Remote Backup Script for Windows NTFS Partitions on LVM Volumes”
I am a Linux user for decades. I have promoted the use of Linux wherever I could. But it’s about time to say the truth: Linux sucks!
Before you draw conclusions I like to add: Microsoft Windows and Apple macOS suck even more.Continue reading “Why Linux Sucks”
