btrfs rescue <subcommand> <args>

btrfs rescue is used to try to recover a damaged btrfs filesystem.

chunk-recover [options] <device>

Recover the chunk tree by scanning the devices

Options

-y

assume an answer of yes to all questions.

Note

Since chunk-recover will scan the whole device, it will be VERY slow especially executed on a large device.

Options

-y

verbose mode.

btrfs rescue returns a zero exit status if it succeeds. Non zero is returned in case of failure.
