Bug Description

Cloud-init bug: https://bugs.launchpad.net/cloud-init/+bug/1556260
Growroot bug: TBD

Before we enable multipathing, we need to fix this in growroot and cloud-init.

Both try to resize the root disk, but both fail. AFAIK both try to achieve the same independently from each other.

Growroot:
Feb 19 13:47:19 ubuntu growroot[915]: + growpart /dev/dm-0 1
Feb 19 13:47:19 ubuntu growroot[915]: FAILED: failed to get start and end for /dev/dm-01 in /dev/dm-0

Cloud-init growpart:
2018-02-19 13:47:19,047 - cc_growpart.py[DEBUG]: '/' SKIPPED: device_part_info(/dev/mapper/360050764008180adc800000000001521-part1) failed: /dev/mapper/360050764008180adc800000000001521-part1 not a partition
