The XFS now has an incompat feature flag to indicate that a filesystem needs to be repaired. The Linux kernel refuses to mount the filesystem that has it set and only the xfs_repair tool is able to clear that flag. The GRUB doesn't have the concept of mounting filesystems and just attempts to read the files. But it does some sanity checking before attempting to read from the filesystem. Among the things which are tested, is if the super block only has set of incompatible features flags that are supported by GRUB. If it contains any flags that are not listed as supported, reading the XFS filesystem fails. Since the GRUB doesn't attempt to detect if the filesystem is inconsistent nor replays the journal, the filesystem access is a best effort. For this reason, ignore if the filesystem needs to be repaired and just print a debug message. That way, if reading or booting fails later, the user is able to figure out that the failures can be related to broken XFS filesystem.

This is GRUB 2, the second version of the GRand Unified Bootloader. GRUB 2 is rewritten from scratch to make GNU GRUB cleaner, safer, more robust, more powerful, and more portable. See the file NEWS for a description of recent changes to GRUB 2. See the file INSTALL for instructions on how to build and install the GRUB 2 data and program files. Please visit the official web page of GRUB 2, for more information. The URL is <http://www.gnu.org/software/grub/grub.html>. More extensive documentation is available in the Info manual, accessible using 'info grub' after building and installing GRUB 2. There are a number of important user-visible differences from the first version of GRUB, now known as GRUB Legacy. For a summary, please see: info grub Introduction 'Changes from GRUB Legacy'
