This looks like a CI error to me, can someone from QE first take a look?

From the initial analysis of the failure, I feel this is not something that can be fixed in ocs-ci. The error is while creating a PVC from cli. This failure is reported on IBM Cloud only and the test case is passing in all other platforms. But I am not sure if csi-driver component is the right fit for this bug.

This test passed in an another run on IBM Cloud platform - https://ocs4-jenkins-csb-ocsqe.apps.ocp4.prod.psi.redhat.com/job/qe-deploy-ocs-cluster-prod/1085/ (OCS 4.7.1-410.ci , RUN ID: 1623374282)
)

Jilju, I agree this is not a csi issue.
After doing some digging around "LimitRanger" looks like this is another resource issue which can be platform specific.
Keeping in OCS for now, but it shouldn't be an OCS issue too.

Doesn't seem to be a blocker for 4.8 unless it is consistently reproducible.

Comment 5 Mudit Agarwal 2021-09-22 14:49:06 UTC

Is this issue still reproducible?

Comment 7 Mudit Agarwal 2021-09-27 10:58:30 UTC

Please reopen if you still see this issue.
