Question 3

Which of the following statements are true regarding OCFS2? (Choose TWO correct answers.)

Options:

A.

OCFS2 is an integral part of Pacemaker and relies on Pacemaker services for functionality.

B.

To avoid the need for shared storage, OCFS2 can replicate the content of its filesystems via the network.

C.

When using OCFS2 with additional cluster software, OCFS2 must be integrated into the overall cluster manager to ensure consistent cluster behaviour.

D.

OCFS2 can be used without any additional software as it contains its own cluster manager, O2CB.

E.

In addition to filesystems, OCFS2 can handle other cluster services such as IP addresses and server daemons.

Question 4
