We probably do want this support in though - I can imagine we might not always need a broken out /boot? At the very least can we get a pointer here to some details about the FS feature? on-disk format stuff has recently been coalesced into libxfs/xfs_format.h http://oss.sgi.com/cgi-bin/gitweb.cgi?p=xfs/xfs.git;a=blob;f=fs/xfs/libxfs/xfs_format.h Other than that, we maybe need to do some buddy coding to do this, as I don't think either grub2 or xfs has great up-to-date documentation... For starters I assume grub2 could just grok new formats, but skip the actual CRC verification... things haven't changed *that* much. -Eric https://www.google.com/search?q=add+grub2+support+for+xfs+crc https://www.mail-archive.com/debian-bugs-dist@lists.debian.org/msg1288553.html wget http://download.opensuse.org/repositories/Base:/System/openSUSE_Factory/src/grub2-2.02~beta2-201.4.src.rpm rpm2cpio grub2-2.02~beta2-201.4.src.rpm | cpio -id ls *xfs* grub2-xfs-Add-helper-for-inode-size.patch grub2-xfs-Convert-inode-numbers-to-cpu-endianity-immediate.patch grub2-xfs-Fix-termination-loop-for-directory-iteration.patch grub2-xfs-V5-filesystem-format-support.patch *** Bug 1220844 has been marked as a duplicate of this bug. *** I have tested grub2-2.02-0.23.fc23.x86_64 installed on an Fedora 21 I succeeded in booting a CentOS 7 with XFS from the fedora boot menu, but I still cannot boot a SLED 12 with XFS from the fedora boot menu. Using my openSUSE 13.2 I can boot CentOS 7 and SLED 12. If you need more information, please advise me, how to create a log from grub2.

From the XFS list: > Just a heads-up: GRUB currently doesn't work on a CRC enabled > file-system. It will print the following error message: > "not a correct XFS inode" This format is still WIP upstream, but we should probably have the issue on the RHEL7 radar since we plan to default to XFS even for /boot. A simple workaround would be to not enable CRCs for the root fs; this may be done by default in any case. So this bug may be a WONTFIX or NOTABUG, but I figured we should at least log the issue. Thanks, -Eric
