Hi Yuanjun,

Unfortunately, the STAR resources you’re requesting are currently in use. Please try again later or consider scheduling your slices in advance using the notebook.

Additionally, could you post your inquiry in the FABRIC General Questions and Discussion forum?

Thanks,
Komal

Hi Yuanjun,

Unfortunately, the MAX resources you’re requesting are currently in use. Please try again later or consider scheduling your slices in advance using the notebook.

Additionally, could you post your inquiry in the FABRIC General Questions and Discussion forum?

Glad to hear that worked! We will work to address this and add support to interrupt/return meaningful error in such cases.

Thanks,

Hi Kriti,

Could you please re-run this notebook: jupyter-examples-rel1.8.1/configure_and_validate/configure_and_validate.ipynb ?
This shall renew any expired keys. Please try your slice again after this. I want to rule out any SSH errors. If you continue to see the error, please share /tmp/fablib/fablib.log

Thanks,
Komal

Authentication failed would explain the SSH errors you are observing. Could you please re-run this notebook: jupyter-examples-rel1.8.1/configure_and_validate/configure_and_validate.ipynb ?

Hi,

Please try the following snippet. Please note that list_sites() should be invoked before show_site().

We will fix this to return a more meaningful error in the next version.


from fabrictestbed_extensions.fablib.fablib import FablibManager as fablib_manager
fablib = fablib_manager()
fablib.list_sites()
fablib.get_resources().show_site("HAWI")


Thanks,

Thank you Justas! I haven’t been able to reproduce this even on JH Stable 1.8 container. Could you please share /tmp/fablib/fablib.log file from your container?

Also, please share the sliceid of your new slice.

Thanks,

Komal

Could you please try this with Beyond Bleeding Edge Container? I wasn’t able to reproduce this issue there. Trying it with 1.8 Stable container now.

Thanks,

Hey Kriti,

Could you please share which JH container were you using when you noticed this issue?

Thanks,

Also, could you please share which JH container are you using?

Hi,

Both your slices  are in Stable State. It seems like a bug in fablib or a race condition which is causing fablib to think the slice is still Configuring.

As a workaround, could you please do the following?

I am trying to reproduce this at my end and would work to fix this. Apologies for the inconvenience!


slice=fablib.get_slice(slice_name)
slice.post_boot_config()
slice.list_nodes();
slice.list_interfaces();

Hi Raghav,

Please set up your JH environment by running the notebook: jupyter-examples-rel1.8.1/configure_and_validate/configure_and_validate.ipynb

This shall setup all the required configuration files and SSH keys. Please try the Wide Area Link notebook or Hello Fabric after that to ensure your configuration works. Please let us know if you run into issues.

Thanks,

Komal

Issue resolved over zoom meeting, the issue was the token.

Token file only had id_token instead of the entire token contents. Downloading the token file and using that resolved the issue.

Please let us know if you run into any other issues. I have taken a note to return a more user friendly error. We will address this in the next release.

Thanks,

Komal

Reached out to Vaneshi via email to request a meeting to work to resolve this!

Thanks,

Hi Raghav,

The data plane interfaces on your VMs connected via L2STS do not have IP addresses configured.

The enp3s0 interface on your VMs is designated as the management interface and should be used solely for SSH access. For your experiment, please use the data plane interfaces, which are enp7s0 on both VMs.

I recommend exploring the JH example—Wide Area Link (Layer 2)—using manual, auto, or user-defined configurations, as it demonstrates how IP addresses should be set up.  Please, let us know if you encounter any further issues.

Snapshot from the VMs:
