Sintomi

The following errors appear in the controller driver logs when attempting to create a volume. The Representational State Transfer (REST) command retrieves the details on the SG. La colonna REST response is "200 ok" but then the logs show "Unable to find storage group".

time="2024-02-14T17:15:03Z" level=debug msg="\n    -------------------------- POWERMAX HTTP REQUEST -------------------------\n    GET /univmax/restapi/100/sloprovisioning/symmetrix/<powermax id>/storagegroup/<storage group> HTTP/1.1\n    Host: 0.0.0.0:2222\n    Accept: application/json;version=100\n    Application-Type: CSI Driver for Dell EMC PowerMax/v2.9.1\n    Content-Type: application/json;version=100\n    Symid: <powermax id>\n    \n"

Then continuing, the REST checks if the volume exists before trying to create it. La colonna REST returns that the volume is not found with a 404 Not Found message, but the code expects an empty list instead.

This behavior then repeats, and the volume is never created.

Causa

The user added a trailing "/" in the values file or powermax-reverseproxy-config e powermax-array-config configmaps when entering the Unisphere for PowerMax endpoint.

https://primary-1.unisphe.re:8443/

The provided values YAML file shows no trailing "/" in the sample.

Risoluzione

Installation should be done using a values file that does not contain the additional "/".
