Public bug reported: Filing a note here in case I forget later.
It looks like GRUB (2.02-beta2-15) in 14.10 doesn't support XFS's new on-disk metadata format that has CRCs. (rationale: https://www.kernel.org/doc/Documentation/filesystems/xfs-self- describing-metadata.txt) mkfs.xfs -m crc=1,finobt=1 /dev/sdXY creates an XFS with the new on- disk format. This is NOT the default, and probably won't be until kernel support for it has been in distros for a while. redhat bug with some patches from Dec 2014: https://bugzilla.redhat.com/show_bug.cgi?id=1001279 I haven't yet dug up any changelogs about those patches getting merged into GRUB's upstream git repo. If there's a PPA, or an easy way to build a .deb from git master (or some other way I can easily test git master on an Ubuntu system), I'd be interested and willing to test this. (It's possible I'm mistaken here, and my boot problem was from using RAID10,f2, rather than from XFS with crc=1. testing now.) ** Affects: grub2 (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1424123 Title: Need to update for XFS crc=1 (non-default) on-disk format change To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1424123/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
