Hi, For this message: ls: cannot access '/var/lib/kubelet/plugins/unity.emc.dell.com/csi_sock': No such file or directory I installed fresh and that was the 2nd message in the logs.  The driver checks to see if the socket exists and if not it is created.  This message should not cause concern. For these messages: time="2021-04-28T11:49:52Z" level=error arrayid=c************** runid=node-2 msg="Cannot read directory: /sys/class/fc_host Error: open /sys/class/fc_host: no such file or directory" … time="2021-04-28T11:49:54Z" level=error runid=2 msg="Cannot read directory: /sys/class/fc_host Error: open /sys/class/fc_host: no such file or directory" It looks like you are using iSCSI, so the FC messages can be ignored.  You could also try to comment out FC in the myvalues.yaml file on install. #- protocol: "FC"  
Received following question   To sum it up, we need you to help us to fix the following error:* ls: cannot access '/var/lib/kubelet/plugins/unity.emc.dell.com/csi_sock': No such file or directorySo provisioning new PVC is not a problem and works as expected but the wan't to know if this is a Bug or error that should be fixed. During our last provision of storage via CSI Unity Driver we encountered the following error:Please take a look at the following commands:k get pvcNAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS AGEpvol1 Bound csivol-dev-it-7d480819bd 12Gi RWO unity-iscsi 9m55spvol2 Bound csivol-dev-it-bc9921b234 10Gi RWX unity-nfs 9m55sk get podsNAME READY STATUS RESTARTS AGEunitytest-0 0/1 Pending 0 10mCSI Unity Driver Node and Controller pods are working as expected...k get pods -n unityNAME READY STATUS RESTARTS AGEunity-controller-77fd49d8c6-bjdb4 5/5 Running 7 20dunity-controller-77fd49d8c6-fgxk2 5/5 Running 0 20dunity-controller-77fd49d8c6-mrdgx 5/5 Running 0 20dunity-node-6528n 2/2 Running 0 18munity-node-9t7b9 2/2 Running 6 60dunity-node-bt2gw 2/2 Running 4 60dbut after troubleshooting logs we found the following error:Endpoint unix:///var/lib/kubelet/plugins/unity.emc.dell.com/csi_sockls: cannot access '/var/lib/kubelet/plugins/unity.emc.dell.com/csi_sock': No such file or directorytime="2021-04-28T11:49:51Z" level=info runid=start msg="Driver Mode:node"time="2021-04-28T11:49:51Z" level=info runid=start msg="X_CSI_UNITY_NODENAME:rzk8qaitw02"time="2021-04-28T11:49:51Z" level=info runid=config-0 msg="*************Synchronizing driver config**************"csi-unity logger initiated.
