Usage: ${0##*/} [OPTION]... [-- <lustre configure options>]
--external-patches=EXTERNAL_PATCHES
Directory similar to lustre/lustre/kernel_patches/ that lbuild should
look for seres and config files in before looking in the lustre
tree.
--extraversion=EXTRAVERSION
Text to use for the rpm release and kernel extraversion.
--timestamp=TIMESTAMP
Date of building lustre in format YYYYMMDDhhmmss
--reusebuild=DIR
Try to reuse old kernel builds from DIR
--kernelrpm=DIR
Path to distro kernel RPM collection
--ccache
Use ccache
--norpm
Unused.
--patchless
Build lustre client only
--patchless-server
Build lustre server without patching the kernel
--distro=DISTRO
Which distro using. Autodetect by default
--kerneldir=KERNELDIR
Directory containing Linux source tarballs referenced by target
files.
--kerneltree=KERNELTREE
Directory containing dirs with Linux source tarballs referenced by target
files. Dir names in format kernel version ('2.6.9', etc.)
--enable-kernel-debug
Build with kernel-<version>.config-debug instead
--linux=LINUX --with-linux=LINUX
Directory of Linux kernel sources. When this option is used, only
Lustre modules and userspace are built.
--lustre=LUSTRE
Path to an existing lustre source tarball to use.
--nodownload
Do not try to download a kernel from downloads.whamcloud.com
--nosrc
Do not build a .src.rpm, a full kernel patch, or a patched kernel
tarball.
--ofed-type
Type of OFED to build with lustre: inkernel, ofa, mlnx, ifs
ofa: OpenFabrics Alliance
mlnx: Mellanox
ifs: Intel True Scale Fabric
--ofed-version
Version of external OFED to build with lustre
--mlnx-version
Version of external Mellanox OFED to build with lustre
--ofed-src
Tarball for either OFED. Tarball must follow below format
OFED-<ofed-version>.tgz regardless of vendors
It's likely that you need to reconstruct the directory name
It must be placed under KERNELTREE directory
--ldiskfs
Build with ldiskfs support. (Deprecated, always true)
--noiokit
Do not build lustre-iokit RPM. Now true by default
--publish
Unused.
--release
Specifies that the files generated do not include timestamps, and
that this is an official release.
--disable-zfs
Build Lustre without ZFS.
--src
Build a .src.rpm, a full kernel patch, and a patched kernel tarball.
--stage=DIR
Directory used to stage packages for release. RPMs will be placed
more or less in DIR/<target>-<arch>, and the tarball will be
placed in DIR.
--target=TARGET
The name of the target to build. The available targets are listed
below.
--xen
Builds a Xen domX kernel.
--set-value
Sets a variable to a given value.
