Bug Description

With the fix for https://bugs.launchpad.net/maas/+bug/1616232, MAAS now uses GPT for partitioning large volumes. However, grub does not appear to be happy. The system has an sda of 8.0 TB and is configured with a 50 GB sda1 as the root filesystem.

From the installation output:

... Installing for i386-pc platform.\ngrub-install: warning: this GPT partition label contains no BIOS Boot Partition; embedding won't be possible.\ngrub-install: warning: Embedding is not possible. GRUB can only be installed in this setup by using blocklists. However, blocklists are UNRELIABLE and their use is discouraged..\ngrub-install: error: will not proceed with blocklists.\nfailed to install grub!\nUnexpected error while running command.\nCommand: ['install-grub', '/tmp/tmp2zcywvz1/target', '/dev/sda']\nExit code: 1\nReason: -\nStdout: ''\nStderr: ''\n"

Versions:

ii curtin-common 0.1.0~bzr418-0ubuntu1~ubuntu16.04.1 all Library and tools for curtin installer
ii maas 2.1.0~beta1+bzr5433-0ubuntu1~16.04.1 all "Metal as a Service" is a physical cloud and IPAM

I currently do not have a machine with 2Tb+ disk to test this issue.

Cool! I'll try to find some time late next week to set up a test. Note that you can probably do a reasonable first test by creating a node that's a KVM virtual machine with a large sparse image file as the virtual drive.

For example:

# cd /var/lib/libvirt/images
# truncate -s 4T test.img

[Create a VM using test.img as the disk and PXE boot against MAAS...]
