Slots Tool

I'm running TrueNAS-SCALE-23.10.0.1 on an old Supermicro motherboard in a Genesys S208B-TWIN-ITX-12G chassis. This chassis has hot swappable 3.5" SAS drive bays oriented in two rows of four drives. My storage drives are connected through an LSI Broadcom SAS 9300-8i HBA. My HBA does not support the LOCATE feature, so I cannot blink LEDs to locate hard drives to replace.

In order to quickly associate which hard drive in TrueNAS corresponds to what physical slot it is stored in I wrote a script. This script uses the description column of TrueNAS's Storage Disks table to label what slot a particular drive is installed in. One caveat with this script is I must run it after every reboot or after I install/remove a hard drive, so running sudo slots is now at the beginning of my disk repalcement workflows.

Installation

Copy slots.sh (attached below) to /usr/local/sbin/slots and then run sudo chmod +x /usr/local/sbin/slots. Afterward you will be able to use the tool anywhere by running `sudo

System Setup: Wii

This is currently incomplete! I did not document all the IOS changes I've done.

I have a 2008 Nintendo Wii, which will have a 2 GB SD (not SDHC) card that holds ProjectM and Homebrew software, and a 32 GB USB flash drive housing my purchased ripped games on the bottom-most USB port. This guide will assume both flash devices are newly formatted with the SD card being FAT16 and FAT32 for the USB drive.

Install Homebrew Software

Convert sequence of JPEG images to MP4 video

ffmpeg -r 24 -pattern_type glob -i '*.JPG' -i DSC_%04d.JPG -s hd1080 -vcodec libx264 timelapse.mp4

• -r 24 - output frame rate
• -pattern_type glob -i '*.JPG' - all JPG files in the current directory
• -i DSC_%04d.JPG - e.g. DSC_0397.JPG
• -s hd1080 - 1920x1080 resolution

Slower, better quality

    Designed for makemkvcon running inside a Docker container writing MKV files to /output.

    The problem:
    makemkvcon creates MKV files with the maximum of 0644 file mode. The current umask limits the maximum file mode, but
    does not itself increase permissions (only decreases). This means when a user has a umask of 0002 and touches a new
    file, it will have permissions of 664. However when makemkvcon runs MKV files will have permissions of 644.

    The solution:
    This code compiles into a shared object which is loaded at the beginning of makemkvcon's execution. This will
