Frequently Asked Questions
Welcome to the Lustre FAQ!
We are building the FAQ up organically. If you have a question that you'd like to see in the FAQ, please post it below.
What is Lustre?
Lustre is a scale-out architecture distributed parallel filesystem. Metadata services and storage are segregated from data services and storage.
What is the difference between a server (MDS/OSS) and a target (MDT/OST)?
A target is the storage device where object (file) or metadata is kept. The servers service request from clients on their behalf. Clients do not access storage directly.
- What is a backing file system?
When is the next Maintenance Release?
There are no longer public Maintenance Releases. Maintenance Releases used to be a public service from the Lustre development team at Intel, but they have decided to begin keeping their maintenance branches and releases private. Only customers and business partners will have direct access to Intel's maintenance releases. For a longer explanation, see Retired Release Terminology.
The Lustre Open Source development community remains committed to regularly creating Major Releases along the master branch.
