Here is another different kind of setup which triggers the problem: /boot ext4 on a md RAID10 (4 HDD) partition / btrfs RAID10 (4 HDD) partition swap on a md RAID0 (4HDD) partition
The boot and kernel are on a MD RAID (software RAID), whereas the rest of the system is using Btrfs RAID. -- 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/ubuntu/+source/grub2/+bug/1274320/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
