It would be good to get the logs from the controller, via:

 

kubectl logs -n vxflexos vxflexos-controller-0 driver

after docker search k8scsi, it created volumesnapshotsclass, but a new issue:

Nodes are ready, but controller not work

[root@k8s-master-01 helm]# kubectl get pods -n vxflexos
NAME READY STATUS RESTARTS AGE
vxflexos-controller-0 2/4 CrashLoopBackOff 22 20m
vxflexos-node-5qfbl 2/2 Running 0 20m
vxflexos-node-c7gtx 2/2 Running 0 20m
vxflexos-node-tt8rx 2/2 Running 0 20m

Thanks tssgery! I found have to wait a long time to download image, and get it work now.

Back to the original problem of not being able to create the volumesnapshotclass...

The workaround, if you see this, is to re-run the install.vxflexos script. The installation is idempotent and will pick up where left off and create the class.

This will be fixed in a future release of the CSI Driver for VxFlex OS
