1 Lustre Parallel Filesystem Client
2 =================================
4 The Lustre file system is an open-source, parallel file system
5 that supports many requirements of leadership class HPC simulation
7 Born from from a research project at Carnegie Mellon University,
8 the Lustre file system is a widely-used option in HPC.
9 The Lustre file system provides a POSIX compliant file system interface,
10 can scale to thousands of clients, petabytes of storage and
11 hundreds of gigabytes per second of I/O bandwidth.
13 Unlike shared disk storage cluster filesystems (e.g. OCFS2, GFS, GPFS),
14 Lustre has independent Metadata and Data servers that clients can access
15 in parallel to maximize performance.
17 In order to use Lustre client you will need to download the "lustre-client"
18 package that contains the userspace tools from http://lustre.org/download/
20 You will need to install and configure your Lustre servers separately.
24 After you installed the lustre-client tools including mount.lustre binary
25 you can mount your Lustre filesystem with:
27 mount -t lustre mgs:/fsname mnt
29 where mgs is the host name or ip address of your Lustre MGS(management service)
30 fsname is the name of the filesystem you would like to mount.
37 Disable posix file locking (Applications trying to use
38 the functionality will get ENOSYS)
41 Enable local flock support, using only client-local flock
42 (faster, for applications that require flock but do not run
46 Enable cluster-global posix file locking coherent across all
49 user_xattr, nouser_xattr
50 Support "user." extended attributes (or not)
52 user_fid2path, nouser_fid2path
53 Enable FID to path translation by regular users (or not)
56 Verify data consistency on the wire and in memory as it passes
57 between the layers (or not).
59 lruresize, nolruresize
60 Allow lock LRU to be controlled by memory pressure on the server
61 (or only 100 (default, controlled by lru_size proc parameter) locks
62 per CPU per server on this client).
64 lazystatfs, nolazystatfs
65 Do not block in statfs() if some of the servers are down.
68 Shrink inode numbers to fit into 32 bits. This is necessary
69 if you plan to reexport Lustre filesystem from this client via
73 Enable mount/umount console messages (or not)
