NAME

       fence_crosslink - Fence agent for cross-link two-node clusters

DESCRIPTION

       This agent helps two-node clusters to tackle the situation where one node lost power, cannot be fenced by
       telling pacemaker that if the node is not reachable over the crosslink cable, we can assume it is dead

       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)

       -a, --crosscableip=[IP]
              Cross-cable IP This parameter is always required.

       -n, --plug=[id]
              Physical plug number on device, UUID  or  identification  of  machine  This  parameter  is  always
              required.

       -T, --timeout=[seconds]
              No ICMP reply in 5 seconds -> Node is considered dead (Default Value: 5)

       -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: ,)

       -C, --separator=[char]
              Separator for CSV created by 'list' operation (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: 0)

       --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)
