A cluster administrator is evaluating GFS2 and OCFS2 for a new cluster. Which statements about the Distributed Lock Manager (DLM) are correct? (Select all that apply.)

The DLM requires a dedicated metadata server to manage locks.

In the event of a node failure, the DLM automatically recovers locks held by that node.

The DLM provides lock modes such as shared and exclusive to control read/write access.

The DLM is used by both GFS2 and OCFS2 to coordinate access to shared storage.

An administrator needs to add a new node to an existing OCFS2 cluster. The new node has been added to /etc/ocfs2/cluster.conf on all nodes. What additional step is required for the new node to mount the OCFS2 file system?

Run fsck.ocfs2 on the new node to prepare the file system.

Run mkfs.ocfs2 on the new node to create a local file system.

Run tunefs.ocfs2 to add the new node to the file system's node list.

Reboot all existing nodes to propagate the configuration.

Which characteristic is a fundamental difference between a cluster file system (such as GFS2) and a distributed file system (such as AFS)?

Cluster file systems use a network file protocol for all I/O, whereas distributed file systems use a local block device.

Cluster file systems provide a global namespace, whereas distributed file systems require each client to mount a separate namespace.

Cluster file systems are only used for read-only workloads, whereas distributed file systems support read-write access.

Cluster file systems require shared storage accessible by all nodes, whereas distributed file systems typically use independent storage on each server.
