MDS config quota

• Assignee: Niu Yawei (Inactive)
• Reporter: Nikitas Angelinas

Description

Version 1.8 uses a tunable named "mdt.quota_type" in order to store quota parameters in config, while version 2.x has a tunable named "mdd.quota_type" for the same purpose. This introduces incompatibility when trying to run a 2.x Lustre instance on top of a filesystem with a 1.8 disk format.
