@schneibva: Can you please try my patch on your /etc/grub.d/00_header file and manually add the word "raid" to the for-in list?
I.e. replace this line: for check_abstraction in lvm ; do with that: for check_abstraction in lvm raid ; do And afterwards run "update-grub", of course. (If you made any mistakes in applying the patch, update-grub will probably fail with an error and you should restore your old 00_header file.) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1274320 Title: Error: diskfilter writes are not supported To manage notifications about this bug go to: https://bugs.launchpad.net/grub/+bug/1274320/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
