bjodah / create-raid1-image-files-for-storing-maverick-ggufs.sh

Created April 21, 2025 15:03

This was a failed attempt to create a mdadm RAID1 xfs filesytem backed by two files on separate NVMe drives (with two separate BTRFS filesystems). Read performance was heavily degraded compared to just reading all files from a single btrfs filesystem.

	#!/bin/bash
	# Raid1 with XFS should perform well:
	# https://www.phoronix.com/review/linux54-hdd-raid/3
	#
	# to benchmakr this, first outside llama.cpp we can do:
	# $ sudo sh -c "sync; echo 3 > /proc/sys/vm/drop_caches"
	# $ time b3sum /mnt/gguf-unsloth-maverick/.../.../...1-of-4.gguf
	set -euo pipefail
	usage() {
	echo " \$ $0 /opt/gguf-unsloth-maverick-backing-1-of-2/disk1.img /cache/gguf-unsloth-maverick-backing-2-of-2/disk2.img"

Using emacs under windows

	1. Install msys2 from msys2.org
	2. run msys2.exe: pacman -Syu, restart, pacman -Su
	3. run mingw64.exe: pamcan -S mingw-w64-x86_64-emacs
	4. create C:\msys2_64\runemacs_patched_path.bat:
	cmd /C "set PATH=C:\msys2_64\mingw64\bin;C:\msys2_64\usr\bin;%PATH% && C:\msys2_64\mingw64\bin\runemacs.exe --daemon"
	5. Super-R shell:startup [RET]
	6. Create shortcut to runemacs_patched_path.bat, call it e.g. "emacs-daemon"
	7. Create a short-cut in Start menu:
	C:\msys2_64\mingw64\bin\emacsclientw.exe -c -n -a "C:\msys2_64\mingw64\bin\runemacs.exe"
