fsck.f2fs - check a Linux F2FS file system fsck.f2fs [ -a enable auto fix ] [ -f enable force fix ] [ -M show file map ] [ -p enable preen mode ] [ -t show stored directory tree ] [ -d debugging-level ] device fsck.f2fs is used to check an f2fs file system (usually in a disk partition). device is the special file corresponding to the device (e.g. /dev/sdXX).

The exit code returned by fsck.f2fs is 0 on success and -1 on failure.

-a " enable auto fix" Enable to run file system check only if a bug was reported by the F2FS kernel module. It is disabled by default.

-f " enable force fix" Enable to fix all the inconsistency in the partition.

-M " show files map" Enable to show all the filenames and inode numbers stored in the image

-p " enable preen mode" Same as "-a" to support general fsck convention.

-t " show stored directory tree" Enable to show every directory entries in the partition.

-d " debug-level" Specify the level of debugging options. The default number is 0, which shows basic debugging messages.

Initial checking code was written by Byoung Geun Kim <bgbg.kim@samsung.com>. Jaegeuk Kim <jaegeuk@kernel.org> reworked most parts of the codes to support fixing any corrupted images. fsck.f2fs is available from git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs-tools.git. mkfs.f2fs(8), dump.f2fs(8), defrag.f2fs(8), resize.f2fs(8), sload.f2fs(8).
