9.2. Creating a fence device

The format for the command to create a fence device is as follows. For a listing of the available fence device creation options, see the pcs stonith -h display.

pcs stonith create stonith_id stonith_device_type [stonith_device_options] [op  operation_action operation_options]

The following command creates a single fencing device for a single node.

# pcs stonith create MyStonith fence_virt pcmk_host_list=f1 op monitor interval=30s

Some fence devices can fence only a single node, while other devices can fence multiple nodes. The parameters you specify when you create a fencing device depend on what your fencing device supports and requires.

For information about the pcmk_host_list and pcmk_host_map parameters, see General properties of fencing devices.

After configuring a fence device, it is imperative that you test the device to ensure that it is working correctly. For information about testing a fence device, see Testing a fence device.
