Hi @Madi.Cristil @safiya ...probably best to move this post into the Kasten Support group. Thanks. 

Hi 
can anyone please help me to resolve the above posted issue.

Thanks

Hello @vishnuvardhan4885,

Would it be possible to run the k10 primer against your storageclass?

curl -s https://docs.kasten.io/tools/k10_primer.sh  | bash /dev/stdin csi -s $storageclass -i gcr.io/kasten-images/k10tools:7.0.1

Thanks

Emmanuel

Hi @EBrockman

Still i am facing the issue. Please suggest on this 

Hello @vishnuvardhan4885,

So, I would recommend taking a look at the Cinder csi snapshotter logs. Primer essentially run a simple snapshot and restore. If the csi driver is having problems performing this task then thee primer will fail. You could send over the snapshotter logs and maybe we can look from there. Outside of that you would likely need to get with Cinder support on why volumesnapshotting is failing. 

Thanks

Emmanuel

Hello @vishnuvardhan4885,

I would also recommend trying the Infrastructure Profile for Cinder. This would allow for K10 to use the Storage API’s to perform the task as well. https://docs.kasten.io/latest/install/storage.html#cinder-openstack

Thanks
