Failover from One Active NFS Server to Another

Figure 1-2 shows a failover from one active NFS server node to another active NFS server node.

Failover from One Active NFS Server to Another

 

 

Before Failover:

 

 

 

 

 

 

 

 

 

 

 

Node_A

 

 

 

Node_B

 

 

 

 

 

Pkg_1

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

disks

 

 

 

 

 

 

 

 

 

 

Pkg_2

disks

After Failover:

Node_A

 

Node_B

 

 

 

Pkg_1

disks

Pkg_2

disks

In Figure 1-2, Node_A is the primary node for Pkg_1, and Node_B is the primary node for Pkg_2. When Node_A fails, Node_B adopts Pkg_1 and becomes the server for both Pkg_1 and Pkg_2.
