• Client Requirements
• Installing Integrated Manager for Lustre software on Clients Running RHEL or CentOS

A client (compute node) accessing a storage appliance must be running Integrated Manager for Lustre software 6.3.0.0 client software. The Lustre file system must first be created or discovered at the Integrated Manager for Lustre software dashboard (see the Integrated Manager for Lustre software Online Help to do this). The Lustre client software must be installed on the client, and then the Lustre file system can be mounted on the client as described in the Online Help.

Client Requirements

Each file system client must be running Red Hat Enterprise Linux (RHEL) or CentOS Linux, version 7.7.

Notes:

• Before using the Red Hat or RHEL software referenced herein, please refer to Red Hat’s website for more information, including without limitation, information regarding the mitigation of potential security vulnerabilities in the Red Hat software.

LNET provides the client network infrastructure required by the Lustre file system and LNET must be configured for each client. See LNET Configuration.

Installing Integrated Manager for Lustre software on Clients Running RHEL or CentOS

To configure a Lustre client running RHEL or CentOS version 7.7, perform these steps:

1. For clients running RHEL or CentOS version 7.7, add a client repository with the following command.

   yum-config-manager --add-repo https://downloads.whamcloud.com/public/lustre/lustre-2.12.4/el7/client/
   

2. Install the required Lustre packages on each client:

   a. Enter (on one line):

   yum install lustre-client
   

   b. Update the bootloader (grub.conf or lilo.conf) configuration file as needed.

   Note: Verify that the bootloader configuration file has been updated with an entry for the new kernel. Before you can boot to a kernel, an entry for it must be included in the bootloader configuration file. Often it is added automatically when the kernel RPM is installed.

3. Launch Integrated Manager for Lustre software and login as administrator. Go to the manager GUI to obtain mount point information:

   a. Go to Configuration > File Systems.

   b. In the table listing available file systems, click the name of the file system to be accessed by the client. A page showing file system details will be displayed.

   c. Click View Client Mount Information. The mount command to be used to mount the file system will be displayed as shown in this example:

   mount -t lustre 10.214.13.245@tcp0:/test /mnt/test
   

4. On the client, enter the mount command provided.
