btrfs-scrub: Start a scrub.

btrfs

$ sudo btrfs scrub start ${path-to-btrfs_mount}

try on your machine

This command initiates a Btrfs scrub process using the "btrfs scrub" tool with root privileges (hence the "sudo" command).

Scrubbing is a process in Btrfs file system that checks data and metadata integrity, and attempts to repair any inconsistencies or errors it finds. It is similar to a disk consistency check or a filesystem integrity check in other file systems.

The "btrfs scrub start" command is used to start the scrub process. It takes a parameter called "${path-to-btrfs_mount}", which should be replaced with the actual mount point of the Btrfs filesystem that you want to scrub. The command should be executed in a terminal or command prompt.

By running this command with root privileges, the system will initiate the Btrfs scrub process on the specified Btrfs filesystem, which will check the integrity of its data and metadata, and automatically repair any detected issues if possible. The scrub process can take some time to complete, depending on the size and complexity of the filesystem.
