Welcome to the fschecker-buildroot wiki!

What is it for?

The tool fschecker checks file-systems for errors. Fschecker-buildroot is a tool built on top of Buildroot.

Once built Fschecker-buildroot is a kernel and rootfs. This can be ideally used as a PXE boot image.

Supported file-systems

Here is a list of supported file-system:

• vfat
• ext*
• xfs
• f2fs
• btrfs

Please note that fschecker also supports logical volumes (LVM2).

How to build?

First you need to clone this repo. Then, execute this commands:

make fschecker_defconfig
make -j `getconf _NPROCESSORS_ONLN`

The resulting kernel and rootfs are located under output/images directory. You simply have to copy bzImage and rootfs.cpio.gz to your PXE server.

Example config for PXElinux:

label fschecker
	menu label FSChecker partition checker
	kernel fschecker/bzImage
	append initrd=fschecker/rootfs.cpio.gz

In this example, both files are stored under the sub-directory fschecker/ of the PXE root dir. Check your PXE for informations about PXE root dir.

How to use?

Once booted, fschecker will build a list of known file-systems. Each partition format is automatically detected then checked. If one partition fails the check, an error is displayed. The system stopd.

If no partitions contains error, the system is restarted.
