Hello everyone,

I am trying to start the lab for this session and is not working.

When I try to start the lab, I receive the following error:

[student@workstation ~]$ lab start storage-external

An error has occurred.

labs.laberrors.LabError: The 'Configuring external iSCSI storage settings' fatal step has failed

[student@workstation ~]$

Does anyone already faced similar issue and have the procedure to fix?

[siaci]

not sure if it can help, but i had a similar issue on ch03s07 and while from the VM I was receiving a similarr error to yours, I could get it working if starting the lab from the classroom webapp

[eddielau]

I try to start from classroom webapp also hit the same error like above.

[Chetan_Tiwary_ · Accepted solution]

@eddielau Try to check if 'storage-external' project exist or not. If it does not - then it is ok , if it does - delete the project and try again.

If this does not help at all, try to delete the entire lab and recreate a fresh lab. Once your OCP cluster is up and active - retry this lab start script.

[eddielau]

I try several times it's not really working, the only way I did is delete entire lab and recreate again fresh lab to resolve it. it seems like sometimes when using workstation to start the lab will hit error. Because I rarely use webapp so no idea if it's same problem or not. 

[Chetan_Tiwary_]

Ok @eddielau So it got that your issue is resolved now ( in a fresh lab).

[fernandoleitao]

Hi

I tried again to run the lab using web classroom, checking the projects, deleted, created again and nothing worked.

After that, I deleted my entire lab and recreated, now worked.

Thanks

[Chetan_Tiwary_]

ok thanks for your inputs, glad it is working for you now.
