Partitioning with Ansible Storage Role: Partitions
The storage role always allowed creating and managing different storage technologies like LVM, LUKS encryption or MD RAID, but one technology seemed to be missing for a long time, and surprisingly, it was the most basic one, the actual partitioning. Support for partition management was always something that was planned for the storage role, but it was never a high priority. From the start, the role could create partitions. When creating a more complex storage setup on an empty disk, for example creating a new LVM volume group or adding a new physical volume to an existing LVM setup, the role would always automatically create a single partition on the disk. But that was all the role could do, just one single partition spanning the entire disk.
