Dear bug triager. This bug was created since a commit was marked with DOCIMPACT.
Your project "openstack/bareon" is set up so that we directly report the documentation bugs against it. If this needs changing, the docimpact-group option needs to be added for the project. You can ask the OpenStack infra team (#openstack-infra on freenode) for help if you need to.

Add option to choose partition alignment mode
Under certain circumstances due to that alignment, the end of
particular partition could cross 1M boundary. And due to actual
partition' bounderies being rounded up, fuel-agent mistakenly
assumes that partition couldn't fit within provided boundaries
and raises errors.
However, some h/w data storages are well known for reporting
relatively huge optimal IO sizes (16M or even bigger), so the 1M
room can't be enough. Thus, optimal aligning is not an option.
In such cases, it's better to proceed with minimal mode.
It's the minimum aligment needed to align the partition properly
to physical blocks which avoids performance degradation.
