Can't deploy CentOS 6 with xfs filesystem

[Søren Sjøstrøm]

Deployment of CentOS 6 fails when defining xfs partitions. It works fine under CentOS 7.
The following error message appears in the log:

I'm using MAAS versin 2.7.1

Hi and thanks for reporting this bug.

The problem is with the get_grub_root() function defined in the curtin-hooks.py file [1], which is part of the CentOS 6 MAAS image. I don't think there is anything that should be fixed on the curtin side. I am marking the curtin task as Invalid and adding a maas-images task.

[Jack Lloyd-Walters (lloydwaltersj)]

I'm closing this as CentOS 6 is EOL, and no longer deployable on MAAS via streams
