Overview
btrfs-inspect-internal is a tool for inspecting Btrfs filesystem internals. It provides a comprehensive view of Btrfs’s data structures and their relationships, enabling administrators and developers to deeply understand the filesystem’s behavior.
Syntax
btrfs-inspect-internal [options] path/to/device/or/mountpoint

-
-h, –help: Display this help message.
-
-v, –verbose: Verbose output.
-
-r, –recursive: Recursively inspect subvolumes.
-
-d, –debug: Enable debug output.
-
-o, –output-file=FILE: Save the output to a file.
Examples
- Inspect a Btrfs filesystem mounted at
/mnt/btrfs
:
btrfs-inspect-internal /mnt/btrfs

/dev/sda1
:
btrfs-inspect-internal -v /dev/sda1
- Recursively inspect a subvolume at
/mnt/btrfs/subvol
:
btrfs-inspect-internal -r /mnt/btrfs/subvol
