NAME¶

fence_rcd_serial - rcd_serial fence agent

DESCRIPTION¶

fence_rcd_serial is a Power Fencing agent that operates a serial cable that toggles a reset of an opposing server using the reset switch on its motherboard. The cable itself is simple with no power, network or moving parts. An example of the cable is available here: https://smcleod.net/rcd-stonith/ and the circuit design is available in the fence-agents src as SVG

The fence agent accepts options on the command line as well as from stdin. Fenced sends parameters through stdin when it execs the agent. The agent can be run by itself with command line options. This is useful for testing and for turning outlets on or off from scripts.

PARAMETERS¶

-o, --action=[action]

Fencing action (Default Value: reboot)

-m, --method=[method]

Method to fence (onoff|cycle) (Default Value: cycle)

--serial-port=[port]

Port of the serial device (Default Value: /dev/ttyS0)

-q, --quiet

Disable logging to stderr. Does not affect --verbose or --debug-file or logging to syslog.

-v, --verbose

Verbose mode. Multiple -v flags can be stacked on the command line (e.g., -vvv) to increase verbosity.

--verbose-level

Level of debugging detail in output. Defaults to the number of --verbose flags specified on the command line, or to 1 if verbose=1 in a stonith device configuration (i.e., on stdin).

-D, --debug-file=[debugfile]

Write debug information to given file

-V, --version

Display version information and exit

-h, --help

Display help and exit

--plug-separator=[char]

Separator for plug parameter when specifying more than 1 plug (Default Value: ,)

--delay=[seconds]

Wait X seconds before fencing is started (Default Value: 0)

--disable-timeout=[true/false]

Disable timeout (true/false) (default: true when run from Pacemaker 2.0+)

--login-timeout=[seconds]

Wait X seconds for cmd prompt after login (Default Value: 5)

--power-timeout=[seconds]

Test X seconds for status change after ON/OFF (Default Value: 20)

--power-wait=[seconds]

Wait X seconds after issuing ON/OFF (Default Value: 2)

--shell-timeout=[seconds]

Wait X seconds for cmd prompt after issuing command (Default Value: 3)

--stonith-status-sleep=[seconds]

Sleep X seconds between status calls during a STONITH action (Default Value: 1)

--retry-on=[attempts]

Count of attempts to retry power on (Default Value: 1)
