limits

======
|
|
|
|
rctl
|
|
----
|
|
|
|
Set resourse limits for targeted jail(s).
|
|
|
|
To add a limit, use ``bastille limits TARGET add OPTION VALUE``.
|
|
|
|
To clear the limits from the system, use ``bastille limits TARGET clear``.
|
|
|
|
To clear the limits, and remove the rctl.conf, so that limits will not be loaded
|
|
on a restart, use ``bastille limits TARGET reset``. This removes the ``rctl.conf`` file,
|
|
and removes any active limits from the system.
|
|
|
|
To remove a limit, use ``bastille limits TARGET remove OPTION``.
|
|
|
|
This file can be edited manually using ``bastille edit TARGET rctl.conf``.
|
|
|
|
Supported actions are ``add``, ``remove``, ``clear``, ``reset``, ``list``, ``show``, and
|
|
``stats``.
|
|
|
|
cpuset
|
|
------
|
|
|
|
Bastille supports limiting CPUs using ``cpuset``. To limit a jail to a specific CPU, use
|
|
``bastille limits TARGET cpu 2,3,4``` where the value (2,3,4) is a comma-separated list of CPUs on
|
|
your system. Bastille will validate the CPUs, and error if they are not available to be used.
|
|
|
|
To adjust the CPU limits, run ``bastille limits TARGET cpu 1,2,3`` again with a new set of CPU
|
|
values. This will overwrite the ``cpuset.conf`` file. This will restrict the targetted jail(s) to
|
|
the specified CPUs.
|
|
|
|
CPU limits are cleared when the jail is stopped, and loaded again on jail start, providing the CPU
|
|
values are present in ``cpuset.conf`` inside the jail directory.
|
|
|
|
Supported actions are ``add``, ``remove``, ``reset``, ``list`` and ``show``.
|
|
|
|
This file can be edited manually using ``bastille edit TARGET cpuset.conf``.
