RESTRICTED-COMMAND

~~~~~~~~~~~~~~~~~~

| **restricted-command** [-M] [--sync]

| { -g *group* *command* | *command* *nodes*... }

Executes a restricted command on the specified nodes. Restricted commands are

not arbitrary, but must reside in

``@SYSCONFDIR@/ganeti/remote-commands`` on a node, either as a regular

file or as a symlink. The directory must be owned by root and not be

world- or group-writable. If a command fails verification or otherwise

fails to start, the node daemon log must be consulted for more detailed

information.

Example for running a command on two nodes::

    # gnt-node restricted-command mycommand \

      node1.example.com node2.example.com

The ``-g`` option can be used to run a command only on a specific node

group, e.g.::

    # gnt-node restricted-command -g default mycommand

The ``-M`` option can be used to prepend the node name to all command

output lines. ``--sync`` forces the opcode to acquire the node lock(s)

in exclusive mode.
