Description of problem (please be detailed as possible and provide log snippests): During the test execution of the test_mds_cache_alert_with_active_node_drain we were running metadata io with cephfs by steps: 1. Create PVC with Cephfs, access mode RWX 2. Create dc pod with Fedora image 3. Copy helper_scripts/meta_data_io.py to Fedora dc pod 4. Run meta_data_io.py on fedora pod script can be found by link https://github.com/red-hat-storage/ocs-ci/blob/e4bcbb284280862d03b7f6b5ab2b40e2727482f3/ocs_ci/templates/workloads/helper_scripts/meta_data_io.py This script triggers high cache usage in scenario when standby-replay mds scaled down, but does not trigger when active node drained, showing the problem is related to active mds node disruption happens Version of all relevant components (if applicable): OC version: Client Version: 4.16.11 Kustomize Version: v5.0.4-0.20230601165947-6ce0bf390ce3 Server Version: 4.16.12 Kubernetes Version: v1.29.8+f10c92d OCS version: ocs-operator.v4.16.2-rhodf OpenShift Container Storage 4.16.2-rhodf ocs-operator.v4.16.1-rhodf Succeeded ODF operator full version: 4.16.2-4 Cluster version: NAME VERSION AVAILABLE PROGRESSING SINCE STATUS version 4.16.12 True False 12h Error while reconciling 4.16.12: the cluster operator insights is not available Does this issue impact your ability to continue to work with the product (please explain in detail what is the user impact)? pottentially Is there any workaround available to the best of your knowledge? no Rate from 1 - 5 the complexity of the scenario you performed that caused this bug (1 - very simple, 5 - very complex)? 3 Can this issue reproducible? 1/1 Can this issue reproduce from the UI? no If this is a regression, please provide more details to justify this: new deployment. Tech preview Steps to Reproduce: 1. Deploy ROSA HCP cluster with ODF and run test_mds_cache_alert_with_active_node_drain 2. 3. Actual results: There was not found alert MDSCacheUsageHigh Expected results: MDSCacheUsageHigh is fired when conditions met Additional info: cluster to capture necessary data will be created upon request to qe
