NAME
stonith - extensible interface for remotely powering down a node in the cluster SYNOPSIS
stonith -h stonith [-s] [-h] -L stonith [-s] [-h] -t stonith-device-type -n stonith [-s] [-h] -t stonith-device-type {name=value... | -p stonith-device-parameters | -F stonith-device-parameters-file} [-c count] [-l] [-S] stonith [-s] [-h] -t stonith-device-type {name=value... | -p stonith-device-parameters | -F stonith-device-parameters-file} [-c count] [-T {reset | on | off}] [nodename] DESCRIPTION
The STONITH module provides an extensible interface for remotely powering down a node in the cluster (STONITH = Shoot The Other Node In The Head). The idea is quite simple: when the software running on one machine wants to make sure another machine in the cluster is not using a resource, pull the plug on the other machine. It's simple and reliable, albeit admittedly brutal. OPTIONS
The following options are supported: -c count Perform any actions identified by the -l, -S and -T options count times. -F stonith-device-parameters-file Path of file specifying parameters for a stonith device. To determine the syntax of the parameters file for a given device type run: # stonith -t stonith-device-type -n All of the listed parameters need to appear in order on a single line in the parameters file and be delimited by whitespace. -h Display detailed information about a stonith device including description, configuration information, parameters and any other related information. When specified without a stonith-device-type, detailed information on all stonith devices is displayed. If you don't yet own a stonith device and want to know more about the ones we support, this information is likely to be helpful. -L List the valid stonith device types, suitable for passing as an argument to the -t option. -l List the hosts controlled by the stonith device. -n Output the parameter names of the stonith device. name=value Parameter, in the form of a name/value pair, to pass directly to the stonith device. To determine the syntax of the parameters for a given device type run: # stonith -t stonith-device-type -n All of the listed parameter names need to be passed with their corresponding values. -p stonith-device-parameters Parameters to pass directly to the stonith device. To determine the syntax of the parameters for a given device type run: # stonith -t stonith-device-type -n All of the listed parameter names need to appear in order and be delimited by whitespace. -S Show the status of the stonith device. -s Silent operation. Suppress logging of error messages to standard error. -T action The stonith action to perform on the node identified by nodename. Chosen from reset, on, and off. Note If a nodename is specified without the -T option, the stonith action defaults to reset. -t stonith-device-type The type of the stonith device to be used to effect stonith. A list of supported devices for an installation may be obtained using the -L option. -v Ignored. EXAMPLES
To determine which stonith devices are available on your installation, use the -L option: # stonith -L All of the supported devices will be displayed one per line. Choose one from this list that is best for your environment - let's use wti_nps for the rest of this example. To get detailed information about this device, use the -h option: # stonith -t wti_nps -h Included in the output is the list of valid parameter names for wti_nps. To get just the list of valid parameter names, use the -n option instead: # stonith -t wti_nps -n All of the required parameter names will be displayed one per line. For wti_nps the output is: ipaddr password There are three ways to pass these parameters to the device. The first (and preferred) way is by passing name/value pairs on the stonith command line: # stonith -t wti_nps ipaddr=my-dev-ip password=my-dev-pw ... The second way, which is maintained only for backward compatibility with legacy clusters, is passing the values in order on the stonith command line with the -p option: # stonith -t wti_nps -p "my-dev-ip my-dev-pw" ... The third way, which is also maintained only for backward compatibility with legacy clusters, is placing the values in order on a single line in a config file: my-dev-ip my-dev-pw ... and passing the name of the file on the stonith command line with the -F option: # stonith -t wti_nps -F ~/my-wtinps-config ... To make sure you have the configuration set up correctly and that the device is available for stonith operations, use the -S option: # stonith -t wti_nps ipaddr=my-dev-ip password=my-dev-pw -S If all is well at this point, you should see something similar to: stonith: wti_nps device OK. If you don't, some debugging may be necessary to determine if the config info is correct, the device is powered on, etc. The -d option can come in handy here - you can add it to any stonith command to cause it to generate debug output. To get the list of hosts controlled by the device, use the -l option: # stonith -t wti_nps ipaddr=my-dev-ip password=my-dev-pw -l All of the hosts controlled by the device will be displayed one per line. For wti_nps the output could be: node1 node2 node3 To power off one of these hosts, use the -T option: # stonith -t wti_nps ipaddr=my-dev-ip password=my-dev-pw -T off node SEE ALSO
