A Pacemaker cluster uses a shared filesystem on a clustered LVM volume. The administrator needs to configure the cluster resources so that DLM, clustered LVM, and the filesystem start in the correct order. Which set of Pacemaker constraints should be created?

Create a group resource containing DLM, clvmd, and the filesystem.

Order DLM before clvmd, and clvmd before the filesystem resource.

Create a colocation constraint to place DLM and the filesystem on the same node.

Order the filesystem before DLM, and DLM before clvmd.

A storage administrator is configuring multipath I/O on a Linux server that connects to a SAN via two Fibre Channel HBAs. The server sees four paths to the same LUN. The administrator wants to ensure that if one path fails, I/O continues without interruption, and that the system uses all available paths for load balancing. Which configuration should be used?

Configure each path as a separate device and use LVM to stripe across them.

Use the 'multipath -a' command to add all paths to a single device without configuring a policy.

Disable multipathd and rely on the operating system's default device mapper to handle path failover.

Enable the multipathd daemon and configure multipath.conf with a policy of 'round-robin' and a failover configuration.

Part of the Topic 362: High Availability Cluster Storage domain, which makes up ~26% of our current practice bank. Linux Professional Institute does not publish an official question count, but from its 90-minute exam (~35–60 total, ~9–16 in this domain), expect 3–5 from this objective — we provide 33 practice questions to prepare you well beyond it.
