NAME¶

fence_gce - Fence agent for GCE (Google Cloud Engine)

DESCRIPTION¶

fence_gce is an I/O Fencing agent for GCE (Google Cloud Engine). It uses the googleapiclient library to connect to GCE. googleapiclient can be configured with Google SDK CLI or by executing 'gcloud auth application-default login'. For instructions see: https://cloud.google.com/compute/docs/tutorials/python-guide

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

--plugzonemap=[plugzonemap]

Comma separated zone map when fencing multiple plugs.

--proxyhost=[proxy_host]

If a proxy is used for internet access, the proxy host should be specified.

--proxyport=[proxy_port]

If a proxy is used for internet access, the proxy port should be specified.

--earlyexit

If an existing reset operation is detected, the fence agent will return before the operation completes with a 0 return code.

--warntimeout=[warn_timeout]

If the operation is not completed within the timeout, the cluster operations are allowed to continue.

--errortimeout=[error_timeout]

If the operation is not completed within the timeout, cluster is notified of the operation failure.

--runonwarn=[run_on_warn]

If a timeout would occur while running the agent, then the supplied command is run.

If a failure would occur while running the agent, then the supplied command is run.

-q, --quiet
