Ok - I filed a few more bugs to cover the aspects of this failure other than the slow response for grub.cfg.
bug 1747927 - grub should not hang waiting for user input when booting from MAAS. bug 1747928 - When a known server in Deploying state boots to the enlisting environment, it should not just power off. bug 1747930 - MAAS should recognize servers that are Powered Off in Deploying state, and do something about it. -- 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: High IO on the system prevents MAAS to provide PXE config in a timely manner (less than 30 secs) 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
