Mirantis Container Cloud (MCC) becomes part of Mirantis OpenStack for Kubernetes (MOSK)!
Starting with MOSK 25.2, the MOSK documentation set will cover all product layers, including MOSK management (formerly MCC). This means everything you need will be in one place. The separate MCC documentation site will be retired, so please update your bookmarks for continued easy access to the latest content.
Enable periodic Ceph performance testing¶
TechPreview
Warning
Performance testing affects the overall Ceph cluster performance. Do not run it unless you are sure that user load will not be affected.
This section describes how to configure periodic Ceph performance testing using Kubernetes batch or cron jobs that execute a fio process in a separate container with a connection to the Ceph cluster. The test results can then be stored in a persistent volume attached to the container.
Ceph performance testing is managed by the KaaSCephOperationRequest
CR that
creates separate CephPerfTestRequest
requests to handle the test run. Once
you configure the perfTest
section of the KaaSCephOperationRequest
spec, it propagates to CephPerfTestRequest
on the managed cluster in the
ceph-lcm-mirantis
namespace. You can create a performance test for a single
or scheduled runs.
