# fsck.erofs(1)

tool to check an EROFS filesystem's integrity

## NAME

fsck.erofs - tool to check an EROFS filesystem's integrity

## SYNOPSIS

**fsck.erofs** \[*OPTIONS*\] *IMAGE*

## DESCRIPTION

fsck.erofs is used to scan an EROFS filesystem *IMAGE* and check the integrity of it.

## OPTIONS

- **-V**, **--version**

  Print the version number of fsck.erofs and exit.

- **-d** *#*

  Specify the level of debugging messages. The default is 2, which shows basic warning messages.

- **-p**

  Print total compression ratio of all files including compressed and non-compressed files.

- **--device=***path*

  Specify an extra blob device to be used together. You may give multiple **--device** options in the correct order.

- **--extract***\[=directory\]*

  Test to extract the whole file system. It scans all inode data, including compressed inode data, which leads to more I/O and CPU load, so it might take a long time depending on the image size.

  Optionally extract contents of the *IMAGE* to *directory*.

- **--no-sbcrc**

  Bypass the on-disk superblock checksum verification.

- **--nid=***#*

  Specify the target inode by its NID for checking or extraction. The default is the root inode.

- **--path=***path*

  Specify the target inode by its path for checking or extraction. If both **--nid** and **--path** are specified, **--path** takes precedence.

- **--\[no-\]xattrs**

  Whether to dump extended attributes during extraction (default off).

- **--xattr-inode-digest**

  Verify per-inode digests recorded as extended attributes during image creation with **mkfs.erofs --xattr-inode-digest**.

- **-h**, **--help**

  Display help string and exit.

- **-a**, **-A**, **-y**

  These options do nothing at all; they are provided only for compatibility with the fsck programs of other filesystems.
