4.2 Installation Instructions
The following installation instructions are for a CentOS 5.2/RHEL5U2 system. The other systems
are similar, but use the correct Lustre client RPMs for your system type from the HP SFS G3.1-0
software tarball /opt/hp/sfs/lustre/client directory.
The Lustre client RPMs that are provided with HP SFS G3.1-0 are for use with CentOS
5.2/RHEL5U2 kernel version 2.6.18_92.1.17.e15. If your client is not running this kernel, you need
to either update your client to this kernel or rebuild the Lustre RPMs to match the kernel you
have using the instructions in
“CentOS 5.2/RHEL5U2 Custom Client Build Procedure” (page 39)
You can determine what kernel you are running by using the uname -r command.
1.
Install the required Lustre RPMs for the kernel version 2.6.18_92.1.17.e15. Enter the following
command on one line:
# rpm -Uvh lustre-client1.6.7-2.6.18_92.1.17.el5_lustre.1.6.7smp.x86_64.rpm \
lustre-client-modules-1.6.7-2.6.18_92.1.17.el5_lustre1.6.7smp.x86_64.rpm
For custom-built client RPMs, the RPM names are slightly different. In this case, enter the
following command on one line:
# rpm -Uvh lustre-1.6.7-2.6.18_92.1.17.el5_200808041123.x86_64.rpm \
lustre-modules-1.6.7-2.6.18_92.1.17.el5_200808041123.x86_64.rpm \
lustre-tests-1.6.7-2.6.18_92.1.17.el5_200808041123.x86_64.rpm
2.
Run the depmod command to ensure Lustre modules are loaded at boot.
3.
For InfiniBand systems, add the following line to /etc/modprobe.conf:
options lnet networks=o2ib0
For 10 GigE systems, add the following line to /etc/modprobe.conf:
options lnet networks=tcp(eth2)
In this example, eth2 is the Ethernet interface that is used to communicate with the HP SFS
system.
4.
Create the mount-point to use for the file system. The following example uses a Lustre file
system called testfs, as defined in
“Creating a Lustre File System” (page 41)
. It also uses
a client mount-point called /testfs. For example:
# mkdir /testfs
NOTE:
The file system cannot be mounted by the clients until the file system is created
and started on the servers. For more information, see
.
5.
For InfiniBand systems, to automatically mount the Lustre file system after reboot, add the
following line to /etc/fstab:
172.31.80.1@o2ib:172.31.80.2@o2ib:/testfs /testfs lustre _netdev,rw,flock 0 0
NOTE:
The network addresses shown above are the InfiniBand IPoIB ib0 interfaces for the
HP SFS G3.1-0 Management Server (MGS) node, and the MGS failover node which must be
accessible from the client system by being connected to the same InfiniBand fabric and with
a compatible IPoIB IP address and netmask.
For 10 GigE systems, to automatically mount the Lustre file system after reboot, add the
following line to /etc/fstab:
172.31.80.1@tcp:172.31.80.2@tcp:/testfs /testfs lustre _netdev,rw,flock 0 0
6.
Reboot the node and the Lustre file system is mounted on /testfs.
