Chromebooks almost universally (except for some very old models) use SSDs, but CrOS source code only contains code to trim a solid state storage device after one or all of three conditions are met, but sometimes it does not do its job well, and of course has no optimization features for HDDs. This shell script presents the option to defrag your drive, and an option to trim your drive. You can do either or both, depending on your needs and whether you've got an SSD or traditional HDD. 10 | 11 | # Usage # 12 | _...enable dev mode, and enter crosh (terminal) first, obviously..._ 13 | 14 | Simply copy trimly.sh to /usr/local/bin with `sudo cp ~/Downloads/trimly.sh /usr/local/bin/`, run `sudo chmod +x trimly.sh` to make it executable, and then run `sudo trimly.sh`. 15 | ## IMPORTANT UPDATE ## 16 | -ChromiumOS and ChromeOS use 12 partitions, whereas CloudReady up until ver. 89.4.44 used 27. Since Neverware's merge with Google, they are making their release timing to be more in tune with Google's, as well as changing the partition layout to the "standard GPT CrOS layout." Firstly, I was not thinking of this during initial development, as the motivation for this came from conversations on the CloudReady forums, and personal use of this script was always on CloudReady. Secondly, the partition numbers in the script would have never worked on ChromiumOS or ChromeOS, and now as of June 18, with the release of 90.1.42, won't work on CloudReady either. To fix all of this, I am making a copy of the current script (ver. 0.4) under the new folder "cros_pre_90", specifically for users who can't (i.e. 32 bit users), or don't want to upgrade. Everyone else (the majority), just use the regular TrImLy script. 17 | 18 | -Version history can be found in ver_hist.txt 19 | 20 | # Yessir # 21 | ...This project is FOSS, and is intended to be used with CloudReady https://www.neverware.com/ and Chromium OS https://www.chromium.org/chromium-os/, builds of which can be downloaded here > https://arnoldthebat.co.uk/wordpress/chromiumos-special-builds/ 22 | 23 | Amazing what can be done with bash, huh? 24 | -------------------------------------------------------------------------------- /cros_pre_90/trimly.sh: -------------------------------------------------------------------------------- 1 | #!/bin/bash 2 | 3 | ## TrImLy 4 | # trimly.sh 5 | ## VER. 0.4.1 6 | 7 | # constants (for coloring stdout) 8 | RED='\033[0;31m' # Red 9 | YEL='\033[1;33m' # Yellow 10 | NC='\033[0m' # No Color 11 | 12 | #start 13 | printf "${RED}--------------------------------------------------------------------------------${NC}\n" 14 | printf "\n" 15 | 16 | printf "${RED}== TrImLy - Your fstrim automator and defrag script for ChomiumOS ==${NC}\n" 17 | printf "\n" 18 | printf "Note: This script must be placed in /usr/local/bin,\n made executable with 'sudo chmod +x trimly.sh',\n and run with sudo (root) priveleges.\n" 19 | printf "\n" 20 | 21 | # conditional defrag (*will not work entirely on bind mounts used on /) 22 | printf "${YEL}You may optionally run e4defrag -v on the stateful_partition and root (/), note this will take some time, and\n is not needed very often on SSDs, but one should use this if installed to an HDD, as ChromiumOS has no auto-defrag. \nPlease answer 1 or 2.▼${NC}\n" 23 | printf "\n" 24 | select yn in "Yes" "No"; do 25 | case $yn in 26 | Yes ) printf "\n" && printf "${YEL}Defragmenting HDD...${NC}" && printf "\n" && e4defrag -v /dev/sda16 && printf "\n ${RED}Continuing...${NC}" && printf "\n"; break;; 27 | No ) printf "\n ${RED}Continuing...${NC}" && printf "\n"; break;; 28 | esac 29 | done 30 | 31 | # conditional trim (for SSD performance and longevity) 32 | # -run fstrim on all relevant partitions and mount points. 33 | # -mount rootfs to temp dir and fstrim them. 34 | printf "\n${YEL}You may now optionally run fstrim on all relevant partitions, mount points,\n and the two rootfs partitions A and B.
