      Yes, another user had a similar issue where they created a new email alias but were registered with FABRIC with different email. Changing your preferred email to point to what you were using before should help resolve this.

      Thanks,

        Good morning Polycarp,

        This something you would have to look at your account settings. I won’t be able to help much there. In the meanwhile, could you please try accessing JHUB again?

        Thanks,

        Komal

          Hi Manas,

          I tried your notebook and was able to figure out the issue. You are specifically passing in the flavor names in your notebook. We do not recommend that, instead we request the user to pass in the specific cores, ram and disk needed.

          In release 1.6, the underlying flavors were re-provisioned to allow for more disk/ram/core combinations which resulted in your slivers being closed due to incorrect configuration.

          Making following changes in your notebook to explicitly pass the cores, ram and disk resolves this issue.

          I have also created a BUG on Control Framework software to return more informative error in such cases for easier debugging. Thank you for reporting this and helping us make the testbed better.


          node=slice.add_node(name=node_names,
          site=site,
          #instance_type=instance_master,
          cores=8,
          ram=12,
          disk=500,
          image=image)

          NOTE: I have emailed you the updated notebook.

          P.S: I am still looking at Redeem Timeout issues if you run into that, will share an update regarding those tomorrow.

          Thanks,

          Komal

            I suspect that multiple email aliases were configured recently for your account. JHUB queries user roles based on your email. In this case, your email address is being passed as polycarpnalela@missouri.edu to JHUB.

            LDAP has your information stored with polycarpnalela@mail.missouri.edu and hence LDAP query returns no information for your account resulting in access denied as indicated in the error below.

            Is it possible for you to change your email configuration to allow polycarpnalela@mail.missouri.edu as the primary email address?

              Are you trying to login to JH using the email address: polycarpnalela@mail.missouri.edu

              Which Identity provider are you using when you login via CILogon?

              Also, could you please share the snapshot of what you see on the following link after logging on to Portal?

              Please also share the cookie contents as well.

              https://portal.fabric-testbed.net/check-cookie

              Also, try opening JH on an incognito browser window and see if that helps.

              Thanks,

                Hello Polycarp,

                 

                Could you please check on the portal if you are a member of a project? This error typically occurs if you are not a member of a project.

                Thanks,

                  @Vaiden – This generally happens if you are not a member of a project. Could you please check on the portal if you are a member of a project?

                    Hi Manas,

                    Thank you for sharing your observations. I see one of the VMs failed to provision on UCSD and resulted in rest of the slivers being closed by orchestrator. Could you please try creating your slice again or share your notebook? I don’t have enough information to debug this further and would like to reproduce in our environment.

                    Appreciate your help with this!

                    Thanks,

                    Komal

                        Could you please check /tmp/fablib/fablib.log for any errors? Also could you please check if you are able to SSH to the VMs in your slice from command line?

                        Also, please share your notebook if possible to help us recreate this in our environment.

                        Thanks,

                        Participant

                          This typically happens, when your SSH keys are not setup properly. By default, fablib executes some default post boot config tasks to configure IP addresses if the notebook setup for auto config is used.

                          Could you please check if your bastion keys are not expired and sliver keys are setup correctly?

                          Validation of keys and configuration can also be done via configure_and_validate.ipynb notebook available under jupyter-examples-*directory. This notebook was added recently and should be available under jupyter-examples-main or jupyter-examples-1.6.1

                          Please let us know if the issue persists.

                          Thanks,

                            @Acheme – Thank you for providing the solution for this issue. Appreciate it!

                             

                            I also wanted to add that Apache Web Server notebook was a bit outdated and not inline with latest Fablib API. I have updated the notebook so that it uses latest Fablib APIs which take care of the networking as well and does not rely on user explicitly configuring IP addresses.

                            If needed, please try the latest version of the notebook from Github: https://github.com/fabric-testbed/jupyter-examples/blob/main/fabric_examples/complex_recipes/apache_web_server/apache_web_server.ipynb

                              Should be resolved now. I just tried a slice and it worked.

                                Hi Acheme,

                                 

                                We are noticing intermittent connectivity issues with TACC switch, resulting in the Network Services failing to provision. That’s resulting the Network being set to None. We are working to resolve this issue and will keep you posted.

                                 

                                Thanks,

                                  Hi Acheme,

                                  Thank you for reporting this issue. TACC worker tacc-w1 where VMs were spawned had issues. We have recovered the worker and provisioning should work now.

                                  Thanks,
