Here is an short explanation what to install on your Servers to set up Lustre quickly. Be aware that this doesn't replace the Documentation and Installation Howtos from Lustre. #1. Building the kernel and the modules You've to download the linux-source package for your kernel and the linux-patch-lustre package. Then patch your kernel with the correct patch file. Build and install it. (Use make-kpkg) To patch the kernel automatically use --added-patches=lustre as build option. Here is the full line how I build my kernel (for those who are not familiar with make-kpkg): make-kpkg --added-patches=lustre --initrd --append-to-version "-my-version" --revision 1 kernel_image Now reboot into this new kernel and install the Lustre modules with: - m-a auto-install lustre Then the kernel and the modules should be there. #2. Preparing the system In the next step install: - lustre-utils This have to be done on every server system. #3. Creating partitions on the OST/MDT/MGS Servers Now you'll have to differentiate between the OST and MDT and MGS Systems We'll assume here that MDT and MGS are on the same system: - Create partitions: - MGS/MDT: mkfs.lustre --fsname spfs --mdt --mgs $device - OST: mkfs.lustre --fsname spfs --ost --mgsnode=$mgsnode@tcp0 $device Additional options are: --reformat - this partition was previously formatted with lustre, reformat it --param="failover.mode=failout" - don't hang the entire fs if an ost isn't available. - Now mount the partitons on the servers: - first the MDT/MGS Server: - mount -t lustre /dev/sda /srv/mdt - now the OST's - mount -t lustre /dev/sda /srv/ost #4. Using the filesystem In order to use the FS, you'll have to mount it on a client. Please note that this client also needs the lustre-modules to be installed. (You can install lustre-source and build the module as described in 1.) - mount -t lustre mgsnode@tcp0:/spfs /mnt #5. Building client modules with DKMS Lustre client-only kernel modules can built against non-patched, vanilla kernels. This may be more convenient than installing the patched kernel and server modules. Installing the lustre-client-modules-dkms package will automatically build modules for all currently installed kernels using DKMS (http://linux.dell.com/dkms/) for which you will need to have the relevant linux-headers packages installed. When a new kernel is installed on the machine, DKMS will automatically build a new set of Lustre client modules. You can also use DKMS to create a new deb containing the pre-built kernel modules, suitable for installing on other machines which may not have a full build environment. - dkms build -m lustre-client-modules -v -k (repeat the above step for all required kernel versions) - dkms mkdeb -m lustre-client-modules -v - dkms mkdsc -m lustre-client-modules -v ########### Please have also a look into the official documentation for Lustre available at: https://wiki.whamcloud.com/display/PUB/Documentation -- Patrick Winnertz Thu, 28 Dec 2007 14:53:25 +0200
