btrfs-inspect-internal: Print superblock's and all of its copies' information.
$ sudo btrfs inspect-internal dump-super --all ${path-to-partition}
try on your machine

This command is used to inspect and dump the superblock information of a Btrfs partition in Linux using the Btrfs file system utility.

Here's a breakdown of this command:

  • sudo: It is a command in Linux that allows users to execute commands with administrative (or root) privileges. It is used here to run the subsequent command with elevated permissions.
  • btrfs: It is the command-line utility for managing Btrfs file systems in Linux.
  • inspect-internal: This command allows you to inspect internal structures of a Btrfs file system.
  • dump-super: It is a subcommand of inspect-internal that dumps information about the superblock(s) of a Btrfs partition.
  • --all: This option is used to dump information about all superblocks of the specified Btrfs partition.
  • ${path-to-partition}: This is a placeholder that should be replaced with the actual path to the Btrfs partition you want to inspect. For example, it could be /dev/sda1 or /dev/nvme0n1p2.

When you execute this command, it will analyze the specified Btrfs partition and provide detailed information about its superblocks. The superblock contains critical metadata and configuration information for the file system. By inspecting the superblocks, you can gather various details about the file system, such as the number of devices involved, UUID, label, and more.
