The *log* (``/var/log``) filesystem size is defaulted for standard platform
|
||||||
|
operation. If there is an expected usage increase due to the application core
|
||||||
|
dump files, it should be increased proportionally to the core dump size and the
|
||||||
|
expected number of core dumps that need to be retained. The core dump storage
|
||||||
|
limits can be explicitly configured using the system ``max_use`` parameter
|
||||||
|
settings that aligns to the core dump storage and retention requirements.
|
||||||
|
|
||||||
|
For example:
|
||||||
|
|
||||||
|
Filesystem Setting:
|
||||||
|
|
||||||
|
``8G (default) + 10G (core dump size x retention count - 5G x 2) = 18G``
|
||||||
|
|
||||||
|
Core Dump Setting:
|
||||||
|
|
||||||
|
``max_use = 10G (core dump size x retention count - 5G x 2)``
