DESCRIPTION¶
Instance attributes available for all "stonith"-class resources and used by Pacemaker's fence daemon, formerly known as stonithd
SUPPORTED PARAMETERS¶
pcmk_host_argument = string [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_host_map = string []
Eg. node1:1;node2:2,3 would tell the cluster to use port 1 for node1 and ports 2 and 3 for node2
pcmk_host_list = string []
Eg. node1,node2,node3
pcmk_host_check = string [dynamic-list]
Allowed values: dynamic-list (query the device via the 'list' command), static-list (check the pcmk_host_list attribute), status (query the device via the 'status' command), none (assume every device can fence every machine)
pcmk_delay_max = time [0s]
This prevents double fencing when using slow devices such as sbd. Use this to enable a random delay for fencing 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_delay_base = string [0s]
This enables a static delay for fencing actions, which can help avoid "death matches" where two nodes try to fence each other at the same time. If pcmk_delay_max is also used, a random delay will be added such that the total delay is kept below that value. This can be set to a single time value to apply to any node targeted by this device (useful if a separate device is configured for each target), or to a node map (for example, "node1:1s;node2:5") to set a different value per target.
pcmk_action_limit = integer [1]
Cluster property concurrent-fencing=true needs to be configured first. Then use this to specify the maximum number of actions can be performed in parallel on this device. -1 is unlimited.
pcmk_reboot_action = string [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]
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]
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]
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]
Some devices need much more/less time to complete than normal. Use this to specify an alternate, device-specific, timeout for 'off' actions.
pcmk_off_retries = integer [2]
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_on_action = string [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]
Some devices need much more/less time to complete than normal. Use this to specify an alternate, device-specific, timeout for 'on' actions.
pcmk_on_retries = integer [2]
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.
pcmk_list_action = string [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]
Some devices need much more/less time to complete than normal. Use this to specify an alternate, device-specific, timeout for 'list' actions.
pcmk_list_retries = integer [2]
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]
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]
Some devices need much more/less time to complete than normal. Use this to specify an alternate, device-specific, timeout for 'monitor' actions.
pcmk_monitor_retries = integer [2]
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]
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]
Some devices need much more/less time to complete than normal. Use this to specify an alternate, device-specific, timeout for 'status' actions.
pcmk_status_retries = integer [2]
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.
