Linus Torvalds 9a19a6db37 Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs Pull vfs updates from Al Viro: - more ->d_init() stuff (work.dcache) - pathname resolution cleanups (work.namei) - a few missing iov_iter primitives - copy_from_iter_full() and friends. Either copy the full requested amount, advance the iterator and return true, or fail, return false and do _not_ advance the iterator. Quite a few open-coded callers converted (and became more readable and harder to fuck up that way) (work.iov_iter) - several assorted patches, the big one being logfs removal * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: logfs: remove from tree vfs: fix put_compat_statfs64() does not handle errors namei: fold should_follow_link() with the step into not-followed link namei: pass both WALK_GET and WALK_MORE to should_follow_link() namei: invert WALK_PUT logics namei: shift interpretation of LOOKUP_FOLLOW inside should_follow_link() namei: saner calling conventions for mountpoint_last() namei.c: get rid of user_path_parent() switch getfrag callbacks to ..._full() primitives make skb_add_data,{_nocache}() and skb_copy_to_page_nocache() advance only on success [iov_iter] new primitives - copy_from_iter_full() and friends don't open-code file_inode() ceph: switch to use of ->d_init() ceph: unify dentry_operations instances lustre: switch to use of ->d_init()		2016-12-16 10:24:44 -08:00

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 the "lustre-client"
package that contains the userspace tools from http://lustre.org/download/

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)
