Software Installation Guide Table of Contents
In this Chapter:
After Integrated Manager for Lustre software is installed, point your web browser to the Integrated Manager for Lustre software dashboard. Use Chrome or Firefox.
For complete instructions on adding servers, configuring LNET, assigning primary and failover servers, configuring PDUs or IPMI, and creating a Lustre file system, see the Integrated Manager for Lustre software online Help.
Adding Storage Servers to a Lustre File System
Adding a storage server consists of identifying the server to Integrated Manager for Lustre software, using either the manager GUI or the Integrated Manager for Lustre software command line interface. A server can be added to an existing file system that was previously discovered and is visible to Integrated Manager for Lustre software in monitor-only mode, or a server can be added to a managed, HA file system created using Integrated Manager for Lustre software.
For managed, HA file systems, when the server is identified, the Integrated Manager for Lustre software agent, Integrated Manager for Lustre software, and specific dependencies (e.g. for Corosync and Pacemaker) are automatically deployed to the new storage server. This simplifies software installation and avoids possible errors.
When the above software is automatically installed on a server, the server becomes capable of running Lustre services for attached storage targets like the MGT, MDT, and OSTs, thereby acting as a gateway between these targets and the network.
The Lustre file system on the storage servers is configured from the Integrated Manager for Lustre software GUI, or the supported command line interface.
Storage servers are typically deployed in a high availability (HA) configuration with shared storage. When a server becomes unavailable, Lustre services for targets that were running on that server are started on another server attached to the same storage (known as “failover”).
For complete instructions on adding servers, assigning primary and failover servers, configuring PDUs or IPMI, and creating a Lustre file system, see the Integrated Manager for Lustre software online Help.
Note: Installing Integrated Manager for Lustre software automatically disables SELinux on all storage servers, because the Lustre file system software is not compatible with SELinux. Installation also configures firewalls on the manager and storage servers.
Administering a Lustre File System
WARNING: To manage Lustre file systems from the command line, you must use the Integrated Manager for Lustre software command line interface (CLI).
WARNING: Modifying a file system manually from a shell on a storage server will interfere with the ability of the Integrated Manager for Lustre software to manage and monitor the file system.
Storage servers created in the manager GUI can be managed using the manager GUI or the command line interface. For information about using the CLI, see the Integrated Manager for Lustre software online Help topic, Using the command line interface.
