fsck.erofs - Man Page
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.
