That way they still work with bootloaders that don't understand md raid. Yes I knew that, I don't know why I wrote 0.9. https://bugzilla.redhat.com/show_bug.cgi?id=1046725#c16 However, both are in approximately the same position at the end of the physical device, and still "work" with bootloaders that don't treat them as members in an array. But this is not considered a good practice. https://bugzilla.redhat.com/show_bug.cgi?id=1046725#c9 If using raid, use a bootloader that understands it. I confirmed in the bug that GRUB2 boots from mdadm metadata version 1.2 superblocks just fine. That's the version we should be using. https://bugzilla.redhat.com/show_bug.cgi?id=1046725#c18 Chris Murphy -- test mailing list test@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test
