+Lustre Parallel Filesystem Client
|
|
|
+=================================
|
|
|
+
|
|
|
+The Lustre file system is an open-source, parallel file system
|
|
|
+that supports many requirements of leadership class HPC simulation
|
|
|
+environments.
|
|
|
+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
|
|
|
+tools from
|
|
|
+https://downloads.hpdd.intel.com/public/lustre/latest-feature-release/
|
|
|
+the package name is lustre-client.
|
|
|
+
|
|
|
+You will need to install and configure your Lustre servers separately.
|
|
|
+
|
|
|
+Mount Syntax
|
|
|
+============
|
|
|
+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.
|
|
|
+
|
|
|
+
|
|
|
+Mount Options
|
|
|
+=============
|
|
|
+
|
|
|
+ noflock
|
|
|
+ Disable posix file locking (Applications trying to use
|
|
|
+ the functionality will get ENOSYS)
|
|
|
+
|
|
|
+ localflock
|
|
|
+ Enable local flock support, using only client-local flock
|
|
|
+ (faster, for applications that require flock but do not run
|
|
|
+ on multiple nodes).
|
|
|
+
|
|
|
+ flock
|
|
|
+ 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.
|
|
|
+
|
|
|
+ 32bitapi
|
|
|
+ Shrink inode numbers to fit into 32 bits. This is necessary
|
|
|
+ if you plan to reexport Lustre filesystem from this client via
|
|
|
+ NFSv4.
|
|
|
+
|
|
|
+ verbose, noverbose
|
|
|
+ Enable mount/umount console messages (or not)
