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-]xattrs

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

−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.
