+Lustre Parallel Filesystem Client
+The Lustre file system is an open-source, parallel file system
+that supports many requirements of leadership class HPC simulation
+Born from from a research project at Carnegie Mellon University,
+the Lustre file system is a widely-used option in HPC.
+The Lustre file system provides a POSIX compliant file system interface,
+can scale to thousands of clients, petabytes of storage and
+hundreds of gigabytes per second of I/O bandwidth.
+Unlike shared disk storage cluster filesystems (e.g. OCFS2, GFS, GPFS),
+Lustre has independent Metadata and Data servers that clients can access
+in parallel to maximize performance.
+In order to use Lustre client you will need to download lustre client
+the package name is lustre-client.
+You will need to install and configure your Lustre servers separately.
+After you installed the lustre-client tools including mount.lustre binary
+you can mount your Lustre filesystem with:
+mount -t lustre mgs:/fsname mnt
+where mgs is the host name or ip address of your Lustre MGS(management service)
+fsname is the name of the filesystem you would like to mount.
+ Disable posix file locking (Applications trying to use
+ the functionality will get ENOSYS)
+ Enable local flock support, using only client-local flock
+ (faster, for applications that require flock but do not run
+ on multiple nodes).
+ Enable cluster-global posix file locking coherent across all
+ client nodes.
+ user_xattr, nouser_xattr
+ Support "user." extended attributes (or not)
+ user_fid2path, nouser_fid2path
+ Enable FID to path translation by regular users (or not)
+ checksum, nochecksum
+ Verify data consistency on the wire and in memory as it passes
+ between the layers (or not).
+ lruresize, nolruresize
+ Allow lock LRU to be controlled by memory pressure on the server
+ (or only 100 (default, controlled by lru_size proc parameter) locks
+ per CPU per server on this client).
+ lazystatfs, nolazystatfs
+ Do not block in statfs() if some of the servers are down.
+ Shrink inode numbers to fit into 32 bits. This is necessary
+ if you plan to reexport Lustre filesystem from this client via
+ verbose, noverbose
+ Enable mount/umount console messages (or not)
+You can get more information at
+OpenSFS website: http://lustre.opensfs.org/about/
+Intel HPDD wiki: https://wiki.hpdd.intel.com
+Out of tree Lustre client and server code is available at:
