Hi @Tej Singh Rana, @unnivkn, all
An issue is being faced in lab- "CHALLENGE 1, KUBERNETES CHALLENGE 1". Any inputs?
• A pv was already created at the beginning of the question.
• While trying to create pvc as first step, I created the pvc in the default name space by mistake - which got bound successfully. And then realizing the namespace mistake, I created another pvc with same details in correct ns now. And then deleted the old pvc in the default ns.
• It resulted in pv failure:

root@controlplane ~ ➜  k get pv,pvc -A
NAME                           CAPACITY   ACCESS MODES   RECLAIM POLICY   STATUS   CLAIM                 STORAGECLASS    REASON   AGE

• Below is the error in the pv:

• Now the issue is PV is in failed state and no PVC is getting bounded to this PV.
I am wondering how to recover from this issue if by mistake it happens in exam?

Hi @Mudit please follow this;

unnivkn:
Hi @Mudit also please retry the lab, looks like something crashed unexpectedly.

#4

Mudit:
Hi @unnivkn, thank you for your inputs. Just wondering what to do in case this kind of scenario/issue occurs in real exam?
Any way to recover the PV?
or the only option is to tell the proctor that the environment is damaged?

#5

unnivkn:
In fact PV should not crash if you do something on PVC, I don’t know what happened in your case. Any way I am not expecting similar scenario in real exam.

Mudit:
thanks for your help @unnivkn :slightly_smiling_face:

Hi @unnivkn
The issue I also faced.
It can be reprocessed in the following steps.
I also wonder how to fix PV, PVC, and SC in this scenario.
