Chapter 4. Removed functionality
Chapter 4. Removed functionality This chapter lists functionalities that were supported in Red Hat OpenShift Data Foundation but are no longer available in OpenShift Data Foundation 4.18. 4.1. MDSCacheUsageHigh alert MDSCacheUsageHigh alert has been removed. This alert was querying rss to send high MDS cache usage warning. However, rss is not the right metrics for this. mds_co_bytes is the correct metric but Ceph does not expose the metric. As a result, wrong alerts were being triggered. The alert has been removed until a better solution is identified.
