Storage Analysis

To perform a full analysis of the storage on your Raspberry Pi, you can use various Linux command-line tools. Here's a step-by-step guide to analyse your storage:

Check the available disks and partitions

sudo fdisk -l

This command lists all the disks and partitions connected to your Raspberry Pi. It provides information about the device names, sizes, and partition layouts.

Check the file system usage

df -h

The df command displays the file system disk space usage. The -h option shows the sizes in a human-readable format.

It provides information about the total size, used space, available space, and mount points of each file system.

Check the directory sizes

du -sh /path/to/directory

The du command estimates the disk space usage of files and directories. The -s option displays a summary for each specified directory, and the -h option shows the sizes in a human-readable format. Replace /path/to/directory with the directory you want to analyse.

Identify large files

sudo find / -type f -size +100M -exec ls -lh {} \;

This command finds all files larger than 100MB (modify the size as needed) starting from the root directory (/). It displays the file sizes and paths. You can adjust the size threshold by modifying the +100M part.

Analyse disk usage visually:

sudo apt install ncdu
ncdu /

ncdu is a disk usage analyzer with an ncurses interface. It provides an interactive way to explore the disk usage of directories and files. Navigate through the directories using arrow keys and press Enter to expand or collapse directories.

Check the disk health (for SD cards):

sudo apt install smartmontools
sudo smartctl -a /dev/mmcblk0

smartmontools is a utility for monitoring the health of storage devices. The -a option displays all the available information about the SD card. Replace /dev/mmcblk0 with the appropriate device name for your SD card.

Check the disk health (for USB drives):

sudo apt install smartmontools
sudo smartctl -a /dev/sda

Similar to the previous step, this command checks the health of a connected USB drive. Replace /dev/sda with the appropriate device name for your USB drive.

By following these steps, you can perform a comprehensive analysis of your Raspberry Pi's storage, including disk partitions, file system usage, directory sizes, large files, visual disk usage, and disk health.

Note: Some commands may require sudo privileges to access system-level information. Make sure to review and understand the commands before executing them, especially when using sudo.

Remember to regularly monitor your storage usage and free up space when necessary to ensure optimal performance of your Raspberry Pi.
