Helm Chart installation on AWS EKS: Unable to attach or mount volumes

[DarkoDevops]

I installed DevLake using Helm chart on my AWS EKS cluster. Used previous instructions from ticket:
#87 but, without success. Still not working.

Helm values.yaml looks like:

I get multiple errors like:

Also tried to set storage class to empty (default) and same behaviour. Any idea?

@IronCore864 @JorgeGar would you mind taking a look at this?

[IronCore864]

@DarkoDevops can you run kubectl get/describe pv/pvc and see what you can get from the output?

A wild guess: do you have the aws-ebs-csi-driver addon enabled in your EKS?

[DarkoDevops]

@IronCore864 I will run it and post it.

Yes, I have aws-ebs-csi-driver addon.

I'm running similar values without any issues. I have mysql in an external database, but that's not the one giving you issues, as per what I see in your comment @DarkoDevops. The key difference I guess is that I have aws ebs csi driver installed in the cluster, rather than it being an add-on. Could you try and get logs from it?
Also, which EKS version are you using?

[DarkoDevops]

@JorgeGar
It's 1.25

It's installed, in cluster, also, added policy, not the add-on.

@JorgeGar It's 1.25

Have you checked the logs of the attacher?

[DarkoDevops]

This is what I have of the pods for ebs:

ebs-csi-controller-78bdbf98ff-574px   5/5     Running   0            2d5h
ebs-csi-controller-78bdbf98ff-hwktx   5/5     Running   2 (8d ago)   8d
ebs-csi-node-46nh7                    3/3     Running   0            8d
ebs-csi-node-dthdq                    3/3     Running   0            2d5h
ebs-csi-node-fpz98                    3/3     Running   0            8d

[JorgeGar]

Honestly, at this point, I'm following the troubleshooting page from AWS, but...
On the ebs-csi-controller, you should see a container called "csi-attacher". Try getting logs from there.

[BrookeKatalon]

Seeing the same issue with imageTag: v0.17.0-beta5

containers have errors like:
MountVolume.SetUp failed for volume "devlake-mysql-localtime" : hostPath type check failed: /etc/localtime is not a file
