do188: cannot start lab
Hello,
Somehow my lab environment was gone. I clicked CREATE to create a new one. It finished. So I clicked OPEN CONSOLE next to Workstation. In a terminal I typed
$ lab start basics-accessing
It does not start.

@riemann Thanks for the confirmation, the cluster usually takes around 15-20 mins to be completely up. You can monitor the cluster status by using the below commands.
From workstation run "ssh lab@utility"
Once you are logged in into utility then run "./wait.sh"
The above will give the current status of the cluster getting ready, once it is ready the scripts will work fine.
Regards,
Wasim

Hello @riemann !
Thanks for reaching out!
What you witnessed is because of the fact that your cluster components were not ready to accept any requests - hence the lab start script failed.
You should wait for approx 20 minutes after you start your lab and donot run any lab script in between.
As Wasim mentioned - you can check the status of your cluster readiness by ssh'ing to utility server as "lab" user and then run ./wai.sh script - it will show the status of its components. Wait for the script to finish - once everything is ready then you can run the lab scripts.
