The stripes are distributed among the OSTs in a round-robin fashion to ensure load balancing. -When a client (a compute node from your job) needs to create or access a file, the client queries the metadata server ( MDS) and the metadata target ( MDT) for the layout and location of the [file's stripes][a]. Once the file is opened and the client obtains the striping information, the MDS is no longer involved in the file I/O process. The client interacts directly with the object storage servers (OSSes) and OSTs to perform I/O operations such as locking, disk allocation, storage, and retrieval. +When a client (a compute node from your job) needs to create or access a file, the client queries the metadata server ( MDS) and the metadata target ( MDT) for the layout and location of the file's stripes.

The client interacts directly with the object storage servers (OSSes) and OSTs to perform I/O operations such as locking, disk allocation, storage, and retrieval. If multiple clients try to read and write the same part of a file at the same time, the Lustre distributed lock manager enforces coherency so that all clients see consistent results.
