Configuring Lustre for Failover
From Obsolete Lustre Wiki
Jump to navigationJump to search
If you plan to enable failover server functionality with Lustre (either on an OSS or MDS), you must add high-availability (HA) software to your cluster software. You can use any HA software package with Lustre.
Heartbeat is one option that supports a redundant system with access to shared (common) storage with dedicated connectivity. Heartbeat can determine the system’s general state. For more information, see Chapter 8:Failover in the Lustre Operations Manual.
