Configuring volume failover using multiple FSCs

You can provide volume failover by assigning multiple FSCs to serve the same storage resource. If the primary FSC fails, the secondary FSC continues to serve files from the volume. Configure this behavior by mounting the same volume on multiple FSCs, giving each FSC a different priority level. The volume is always served by the available (alive) FSC with the lowest assigned priority. In the following example, two FSCs mount the testvol volume. The primary FSC is fsc3. It is assigned priority level 0. FSC fsc4 acts as a backup server. It is assigned priority level 1. Look at the configuration for fscgroup g3, at the bottom of the code example. Both of the FSCs mount the testvol volume, each with a different volume priority value. If fsc3 is alive it will serve testvol, fsc4 will only serve testvol if fsc3 is down. Copy ... <volume id="myvol" root="data/myvol/>
