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

fsck.erofs [OPTIONS] IMAGE

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

Print the version number of fsck.erofs and exit.
Specify the level of debugging messages. The default is 2, which shows basic warning messages.
Print total compression ratio of all files including compressed and non-compressed files.
Specify an extra blob device to be used together. You may give multiple --device options in the correct order.
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).
Display help string and exit.
These options do nothing at all; they are provided only for compatibility with the fsck programs of other filesystems.
