and objectives

OpenIMP wanted 42on to give them trusted and contextual advise based on some issues they ran into within their Ceph cluster.

Extension of knowledge

42on acted as an extension of OpenIMP's technical knowledge.

Redesigning for growth

The long-term objective is to redesign the architecture in such a way that it allows the cluster to grow over time.

Improved stability and performance

The short-term objective was to improve the stability of the cluster and enable good performance.

External and professional advise

Specifically, OpenIMP wanted to get external and professional advice on how to reduce the number of placement groups.

Best practices

42on answered some questions OpenIMP had related to the best practices when creating, recreating, or deleting OSDs.

Monitor health status

42on also gave contextual advise on how to get all the monitors running on the same version and overall to keep the cluster at health status = HEALTH_OK.

Services provided to OpenIMP


We scheduled time with OpenIMP to discuss the objectives and gave trusted advice based on contextual information.


As a result of the provided consultancy, we helped OpenIMP to keep their Ceph cluster on the status of HEALTH_OK.

Supporting in issues

We supported OpenIMP with getting their number of placement groups in their pools down to a healthy number.

Stability and performance

We gave OpenIMP specific advice on how to improve their stability and performance to further refine all aspects of their music platform.

Architecture renewal

In addition, we gave OpenIMP further advise on how to redesign their current architecture in such a way that it allows for further growth.


We ensured a smooth and efficient way of working as an extension of the team, exactly how open source support is supposed to be.
