btrfs-rescue: Fix device size alignment related problems (e.g. unable to mount the filesystem with super total bytes mismatch).
$ sudo btrfs rescue fix-device-size ${path-to-partition}
try on your machine
The command sudo btrfs rescue fix-device-size ${path-to-partition}
is used to fix the size of a Btrfs filesystem device.
Here's a breakdown of the command:
sudo
is a command in Linux and Unix systems that allows a user with proper permissions to execute a command as a superuser or another user.btrfs
is the command-line utility for managing Btrfs (B-tree file system), a modern file system for Linux operating systems.rescue
is a subcommand inbtrfs
that provides functionality to rescue and recover data from a damaged or corrupted Btrfs filesystem.fix-device-size
is a specific rescue subcommand inbtrfs
that is used to repair the device size of a Btrfs filesystem.${path-to-partition}
is a placeholder that denotes the path referring to the Btrfs filesystem device or partition. It should be replaced with the actual path to the device/partition (e.g.,/dev/sdb1
).
Therefore, when you run this command with proper permissions and provide the correct path to the Btrfs device/partition, it will attempt to fix the size of the device and potentially resolve any issues related to the device size within the Btrfs filesystem.
This explanation was created by an AI. In most cases those are correct. But please always be careful and
never run a command you are not sure if it is safe.
