Log in grafana UI and check metrics for "Nodes" 2. 3. Actual results: can not show Disk Space Usage Expected results: could show Disk Space Usage Additional info:
I cannot reproduce this with Nodes having only one disk attached, let me retest with nodes having more disks attached.
ok, I can reproduce this on nodes having more than one filesystem, working on a fix.
FYI: The following upstream PR has been filed: https://github.com/kubernetes-monitoring/kubernetes-mixin/pull/68
cluster monitoring operator PR: https://github.com/openshift/cluster-monitoring-operator/pull/83
@junqi: the cluster monitoring operator PR got merged, do you mind to retest?

(In reply to Junqi Zhao from comment #6) > Will test it when I get the build which induce the fix sorry, typo Will test it when I get the build which include the fix
Please change to ON_QA, issue is fixed, could view Disk Space Usage on grafana UI now cluster monitoring images version v3.11.0-0.25.0.0 # openshift version openshift v3.11.0-0.25.0
