5.8. Additional Fencing Configuration Options

Table 5.2, “Advanced Properties of Fencing Devices” summarizes additional properties you can set for fencing devices. Note that these properties are for advanced use only.

Table 5.2. Advanced Properties of Fencing Devices

FieldTypeDefaultDescription
pcmk_host_argument string port An alternate parameter to supply instead of port. Some devices do not support the standard port parameter or may provide additional ones. Use this to specify an alternate, device-specific, parameter that should indicate the machine to be fenced. A value of none can be used to tell the cluster not to supply any additional parameters.
pcmk_reboot_action string reboot An alternate command to run instead of reboot. Some devices do not support the standard commands or may provide additional ones. Use this to specify an alternate, device-specific, command that implements the reboot action.
pcmk_reboot_timeout time 60s Specify an alternate timeout to use for reboot actions instead of stonith-timeout. Some devices need much more/less time to complete than normal. Use this to specify an alternate, device-specific, timeout for reboot actions.
pcmk_reboot_retries integer 2 The maximum number of times to retry the reboot command within the timeout period. Some devices do not support multiple connections. Operations may fail if the device is busy with another task so Pacemaker will automatically retry the operation, if there is time remaining. Use this option to alter the number of times Pacemaker retries reboot actions before giving up.
pcmk_off_action string off An alternate command to run instead of off. Some devices do not support the standard commands or may provide additional ones. Use this to specify an alternate, device-specific, command that implements the off action.
pcmk_off_timeout time 60s Specify an alternate timeout to use for off actions instead of stonith-timeout. Some devices need much more or much less time to complete than normal. Use this to specify an alternate, device-specific, timeout for off actions.
pcmk_off_retries integer 2 The maximum number of times to retry the off command within the timeout period. Some devices do not support multiple connections. Operations may fail if the device is busy with another task so Pacemaker will automatically retry the operation, if there is time remaining. Use this option to alter the number of times Pacemaker retries off actions before giving up.
pcmk_list_action string list An alternate command to run instead of list. Some devices do not support the standard commands or may provide additional ones. Use this to specify an alternate, device-specific, command that implements the list action.
pcmk_list_timeout time 60s Specify an alternate timeout to use for list actions instead of stonith-timeout. Some devices need much more or much less time to complete than normal. Use this to specify an alternate, device-specific, timeout for list actions.
pcmk_list_retries integer 2 The maximum number of times to retry the list command within the timeout period. Some devices do not support multiple connections. Operations may fail if the device is busy with another task so Pacemaker will automatically retry the operation, if there is time remaining. Use this option to alter the number of times Pacemaker retries list actions before giving up.
pcmk_monitor_action string monitor An alternate command to run instead of monitor. Some devices do not support the standard commands or may provide additional ones. Use this to specify an alternate, device-specific, command that implements the monitor action.
pcmk_monitor_timeout time 60s Specify an alternate timeout to use for monitor actions instead of stonith-timeout. Some devices need much more or much less time to complete than normal. Use this to specify an alternate, device-specific, timeout for monitor actions.
pcmk_monitor_retries integer 2 The maximum number of times to retry the monitor command within the timeout period. Some devices do not support multiple connections. Operations may fail if the device is busy with another task so Pacemaker will automatically retry the operation, if there is time remaining. Use this option to alter the number of times Pacemaker retries monitor actions before giving up.
pcmk_status_action string status An alternate command to run instead of status. Some devices do not support the standard commands or may provide additional ones. Use this to specify an alternate, device-specific, command that implements the status action.
pcmk_status_timeout time 60s Specify an alternate timeout to use for status actions instead of stonith-timeout. Some devices need much more or much less time to complete than normal. Use this to specify an alternate, device-specific, timeout for status actions.
pcmk_status_retries integer 2 The maximum number of times to retry the status command within the timeout period. Some devices do not support multiple connections. Operations may fail if the device is busy with another task so Pacemaker will automatically retry the operation, if there is time remaining. Use this option to alter the number of times Pacemaker retries status actions before giving up.
pcmk_delay_base time 0s Enable a base delay for stonith actions and specify a base delay value. This prevents double fencing when different delays are configured on the nodes. Use this to enable a static delay for stonith actions. The overall delay is derived from a random delay value adding this static delay so that the sum is kept below the maximum delay.
pcmk_delay_max time 0s Enable a random delay for stonith actions and specify the maximum of random delay. This prevents double fencing when using slow devices such as SBD. Use this to enable a random delay for stonith actions. The overall delay is derived from this random delay value adding a static delay so that the sum is kept below the maximum delay.
pcmk_action_limit integer 1 The maximum number of actions that can be performed in parallel on this device. The cluster property concurrent-fencing=true needs to be configured first. A value of -1 is unlimited.
pcmk_on_action string on For advanced use only: An alternate command to run instead of on. Some devices do not support the standard commands or may provide additional ones. Use this to specify an alternate, device-specific, command that implements the on action.
pcmk_on_timeout time 60s For advanced use only: Specify an alternate timeout to use for on actions instead of stonith-timeout. Some devices need much more or much less time to complete than normal. Use this to specify an alternate, device-specific, timeout for on actions.
pcmk_on_retries integer 2 For advanced use only: The maximum number of times to retry the on command within the timeout period. Some devices do not support multiple connections. Operations may fail if the device is busy with another task so Pacemaker will automatically retry the operation, if there is time remaining. Use this option to alter the number of times Pacemaker retries on actions before giving up.
