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.
