Device definition commands:¶

-R, --register=value

Register the named stonith device. Requires: --agent. Optional: --option, --env-option.

-D, --deregister=value De-register the named stonith device.

-r, --register-level=value

Register a stonith level for the named target, specified as one of NAME, @PATTERN, or ATTR=VALUE. Requires: --index and one or more --device entries.

-d, --deregister-level=value

Unregister a stonith level for the named target, specified as for --register-level. Requires: --index.

Queries:¶

-l, --list=value

List devices that can terminate the specified host. Optional: --timeout.

-L, --list-registered

List all registered devices. Optional: --timeout.

-I, --list-installed

List all installed devices. Optional: --timeout.

-s, --list-targets=value

List the targets that can be fenced by the named device. Optional: --timeout.

-M, --metadata

Show agent metadata. Requires: --agent. Optional: --timeout.

-Q, --query=value

Check the named device's status. Optional: --timeout.

-H, --history=value

Show last successful fencing operation for named node (or '*' for all nodes). Optional: --timeout, --cleanup, --quiet (show only the operation's epoch timestamp), --verbose (show all recorded and pending operations), --broadcast (update history from all nodes available).

-h, --last=value

Indicate when the named node was last fenced. Optional: --as-node-id.

-K, --validate

Validate a fence device configuration. Requires: --agent. Optional: --option, --env-option, --quiet (print no output, only return status).

Fencing Commands:¶

-F, --fence=value

Fence named host. Optional: --timeout, --tolerance.

-U, --unfence=value

Unfence named host. Optional: --timeout, --tolerance.

-B, --reboot=value

Reboot named host. Optional: --timeout, --tolerance.

-C, --confirm=value

Tell cluster that named host is now safely down.

Additional Options:¶

-a, --agent=value

The agent to use (for example, fence_xvm; with --register, --metadata, --validate).

-o, --option=value

Specify a device configuration parameter as NAME=VALUE (may be specified multiple times; with --register, --validate).

-e, --env-option=value Specify a device configuration parameter with the

specified name, using the value of the environment variable of the same name prefixed with OCF_RESKEY_ (may be specified multiple times; with --register, --validate).

-T, --tag=value

Identify fencing operations in logs with the specified tag; useful when multiple entities might invoke stonith_admin (used with most commands).

-v, --device=value

Device ID (with --register-level, device to associate with a given host and level; may be specified multiple times).

-i, --index=value

The stonith level (1-9) (with --register-level, --deregister-level).

-t, --timeout=value

Operation timeout in seconds (default 120; used with most commands).

-n, --as-node-id

(Advanced) The supplied node is the corosync node ID (with --last).

--tolerance=value

(Advanced) Do nothing if an equivalent --fence request succeeded less than this many seconds earlier (with --fence, --unfence, --reboot).
