This adds drivers/staging/lustre/README.txt with some basic information about Lustre and how to use it.

This is necessary + if you plan to reexport Lustre filesystem from this client via + NFSv4. + + verbose, noverbose + Enable mount/umount console messages (or not) + +More Information +================ +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: +http://git.whamcloud.com/fs/lustre-release.git + +Latest binary packages: +http://lustre.opensfs.org/download-lustre/ -- 1.9.3 _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
