Hello @Hae

Thank you for reaching out

From the below error, it seems that there could be some issue with the volume

Warning FailedAttachVolume 108s attachdetach-controller AttachVolume.Attach failed for volume "pvc-33f9624d-4d90-48fa-8469-02a104df1d10" : rpc error: code = DeadlineExceeded desc = volume pvc-33f9624d-4d90-48fa-8469-02a104df1d10 failed to attach to node cdppvc2.hadoop.com with

Can you please check the status of the above volume from Longhorn UI? Is that volume in good health or bad health?

Re: Failed Initialize embedded Vault while installing DataServices.

Hae — Fri, 12 Apr 2024 06:23:45 GMT

Thank you for your answer @upadhyayk04

I can't access the longhorn UI.

[Storage UI] link in ECS does not working.

I think longhorn does not good status now, What should I checnk?

upadhyayk04 — Fri, 12 Apr 2024 06:26:18 GMT

Hello @Hae

You might need to check the status of longhorn pods and see why they are failing and need to fix them

# kubectl -n longhorn-system get pods

Then you will need to describe the pods which are failing that would help us know why they are failing

Hello,

Thank you for the update

What about pods in other namespaces are they running fine, especially in cdp namespace and kube-system namespace? Is the DB pod running fine

You might need to check kubelet logs to know more about the problem

Hello,

Based on the error mentioned in the stack trace and the above output it seems that the vault itself is deleted somehow. Do you see vault pods present there?

@upadhyayk04

I have got the reason why because of iscsi problem.

I think actually It will not happen in normal cases because no one try to re-install if It installed successfuly.

Anyway to solve this problem, I had to delete all related iscsi, and iscsi pacakges before re-install.

Thank you.
