A two-node cluster uses a shared filesystem that requires the Distributed Lock Manager (DLM) to coordinate access. The cluster administrator needs to ensure that DLM is started before the filesystem is mounted and that it is properly managed by Pacemaker. Which resource configuration should be used?

Start DLM manually on each node before starting Pacemaker.

Create a Pacemaker clone resource for DLM and add an ordering constraint so the filesystem resource starts after DLM.

Configure DLM as a systemd service and rely on systemd to start it before the filesystem mount.

Create a Pacemaker primitive resource for DLM and add a colocation constraint with the filesystem.

A Linux server is connected to a SAN via two Fibre Channel HBAs, each with two paths to the storage array. The administrator notices that the multipath device is not being created automatically, and the system shows four separate SCSI devices. They have installed device-mapper-multipath and started multipathd. What is the most likely reason for the issue?

The WWIDs of the paths are not identical, so multipathd does not recognize them as the same device.

The 'path_grouping_policy' is set to 'failover', which prevents the creation of a multipath device.

The multipath.conf file does not have a 'blacklist' entry for the local disks, causing multipathd to ignore the SAN paths.

The 'multipath' command was not run to create the multipath device.

What is the main purpose of Clustered LVM (clvm)?

To encrypt logical volumes in a cluster

To allow multiple cluster nodes to share the same volume group and logical volumes

To provide a distributed filesystem across cluster nodes

To provide high availability for a single node's logical volumes

362.2 Cluster Storage Access (weight: 3) LPIC-3-HIGH-AVAILABILITY Practice Questions (Page 3)

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.
