Root disk partitions

Mogan supports custom partitions for root disk with partition images, meaning that users can specify partitions such as root_gb, ephemeral_gb, and swap_mb when claiming a server. But after the deployment the root partition may not like what your specified, as the backend driver makes the root partition the last partition which enables tools like cloud-init's growroot utility to expand the root partition until the end of the disk.

Note

Whole disk images, on the contrary, not support partitions, passing partitions to server creation results in a fault and will prevent the creation from happening.
