Hello Folks
I've installed the Kasten on my K8s cluster.
When I go to the `Settings/System Information` section, I see that in `Storage Classes` section, it automatically recognizes my StorageClasses
* One `gp2`
* One `efs`

---

The `gp2` is in `Valid` Status, but, the `efs-sc` is in `Failed` Status.

When I hit the `revalidate`, I'll see that it creates a Pod and a PVC.

The PVC is stuck at the `Pending` and after a while, the task will fail again and delete those PVC and Pod

Here is the `describe` of that PVC:

```shell
$ k -n kasten-io describe pvc kanister-tools-rzbr6

I appreciate any help.
 

 

P.S: I spend this issue on Kanister Github as well

See there for a nice view, the formatting here, is not good :D

Hello @alifiroozi80 

 

So this is a hardlimit of the EFS CSI driver, my guess is a configuration issue related to the “Path” attribute making the creation of the PVC volume past 100 character’s. Please review the link below on more about the 100 character limit. 

 

https://docs.aws.amazon.com/efs/latest/ug/efs-access-points.html

 

Thanks

The PVC access point name is likely auto-generated from the storage class using `MYCOMPANYNAME_eks_dynamic_provisioning` as basePath and something like `${.PVC.namespace}/${.PVC.name}` as a subPathPattern.
Now the K10 is trying to create a mount point with that storage class for `kanister-tools-rzbr6-c13ca19e-62c8-42d5-8a93-55068f65f26c` PVC, which looks like dynamically generated and just happens to go over 100 characters together with the rest of the path.

As a workaround you can cut down the pattern or basePath or change the subPathPattern in your storage class if that’s possible.

Thanks @Daniil.Fedotov

It’s worked after I delete the `basePath` from storage class
