+
+=========================================
+Change the Default Coredump Configuration
+=========================================
+
+You can change the default core dump configuration used to create *core*
+files. These are images of the system's working memory used to debug crashes or
+abnormal exits.
+
+.. rubric:: |context|
+
+The editable parameters and their defaults are as follows:
+
+``ProcessSizeMax``
+ The maximum size of cores that will be processed.
+
+ Default: 2G
+
+ Minimum: 0
+
+``ExternalSizeMax``
+ The maximum size of cores to be saved.
+
+ Default: 2G
+
+ Minimum: 0
+
+``MaxUse``
+ Sets a maximum diskspace usage by cores.
+
+ Default: *unset*
+
+``KeepFree``
+ Sets the minimum amount of disk space to keep free when saving cores.
+
+ Default: 1G
+
+ Minimum: 1G
+
+Maximum values for each configurable coredump parameter depend on system capacity.
+
+The parameters accept integer/float values followed by a letter representing
+the unit of measurement.
+
+* ``B`` = Bytes
+* ``K`` = Kilobytes
+* ``M`` = Megabytes
+* ``G`` = Gigabytes
+* ``T`` = Terabytes
+* ``P`` = Petabytes
+* ``E`` = Exabytes
+
+The value 0 (zero) is accepted by parameters ``ProcessSizeMax``,
+``ExternalSizeMax`` and ``MaxUse``.
+
+.. Note::
+ Other, non-configurable, parameters are:
+
+ * ``Storage`` = external
+ * ``Compress`` = yes
+ * ``JournalSizeMax`` = 767M
+
+
+For more information on these values, see
+https://man7.org/linux/man-pages/man5/coredump.conf.5.html
+
+
+.. rubric:: |prereq|
+
+Ensure that you have sufficient storage available on the host's ``log``
+filesystem. See :ref:`resizing-filesystems-on-a-host` for more information
+about adjusting it's size.
+
+
+.. rubric:: |eg|
+
+When you configure a parameter, it will be replicated to the ``coredump.conf`` file of all
+existing nodes (controllers, workers, storages).
+
+* To add a coredump service parameter:
+
+ .. code-block:: none
+
+ ~(keystone_admin)]$ system service-parameter-add platform coredump <parameter>=<value>
+
+* To modify an existing coredump service parameter:
+
+ .. code-block::
+
+ ~(keystone_admin)]$ system service-parameter-modify platform coredump <parameter>=<value>
+
+* To delete an existing coredump service parameter:
+
+ .. code-block::
+
+ ~(keystone_admin)]$ system service-parameter-delete <uuid>
+
+ .. note::
+
+ When a parameter is deleted, its value will reset to the default.
+
+
+Where <parameter> can be one of:
+
+* ``process_size_max``
+* ``external_size_max``
+* ``max_use``
+* ``keep_free``
+
+The following example sets ``ExternalSizeMax`` to 3 gigabytes.
+
+.. code-block:: none
+
+ ~(keystone_admin)]$ system service-parameter-add platform coredump external_size_max=3G
+
+.. note::
+
+ Configuring a parameter raises the 250.001 *controller-0 Configuration
+ is out-of-date* adarm. A lock/unlock is required to clear it. For more
+ information, see :ref:`locking-a-host-using-the-cli` and
+ :ref:`unlocking-a-host-using-the-cli`.
