Jason's feedback was that, after making the changes to the storage configuration of his environment, deploying the test grubx64.efi doesn't have any effect on the MAAS server's response time to tftp requests. So at this point it's not at all clear that the grub change, while correct, helps with this high-level symptom.
It has also been suggested that each udp retry is generating a separate database query from MAAS. That is absolutely a MAAS bug if true, and not something that can or should be fixed in GRUB. ** Changed in: grub2 (Ubuntu) Importance: Critical => Medium -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1743249 Title: Failed Deployment after timeout trying to retrieve grub cfg To manage notifications about this bug go to: https://bugs.launchpad.net/maas/+bug/1743249/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
