# IMPORTANT PREREQUISITES to creating an HA Lustre file system

Contents

A high-availability Lustre file system managed by Intel® Manager for Lustre* software requires that your entire storage system configuration and all interfaces comply with a pre-defined configuration. Intel® Manager for Lustre* software performs LNet configuration assuming that each server is connected to a high-performance data network, which is the Lustre network LNet. For detailed information, see the section High Availability Configuration Specification in the Intel® Enterprise Edition for Lustre* Software Installation Guide. Also see the guide Lustre* Installation and Configuration using Intel® EE for Lustre* Software and OpenZFS.

Caution: When initially setting up your storage system, take care in selecting block device names because these cannot be changed after the file system has been created using Intel® Manager for Lustre* software. You should NOT make configuration changes to file system servers or their respective volumes/targets outside of Intel® Manager for Lustre* software. Doing so will defeat the ability of Intel® Manager for Lustre* software to monitor or manage the file system, and will make the file system unavailable to clients. Re-labeling these device names during multipath configuration will break the HA configuration established by Intel® Manager for Lustre* software.
