Thank you for reporting this! It’s a bug, for now I have patched the JH with the fix. I will push it to the github repo as well.

Thanks,

Hi Nagmat,

Could you please check if your bastion keys are still valid? Also, could you please share and check for errors in /tmp/fabric/fablib.log ?

Thanks,
Komal

Hi Nagmat,

I don’t see any failures for this slice either. It seems like this slice was deleted on 2023-05-16 17:31:42 UTC.

However, I do see that, another slice created by you yesterday failed with “Insufficient resources error” which would explain the notebook behavior.

Reservation ID: fb7939b5-8f8b-4517-a975-3da648a190c3 Slice ID: 55c64491-4edc-44cc-885f-264f9fa4cbc2

Hi Nagmat,

Could you please share slice id for the slice(s) if possible? Also, you could check in Portal under Experiment->Slices, please select “Include Dead/Closing” slices. Any errors that occurred in those slices should be displayed when you view the slice on the portal.

Thanks,
Komal

The maintenance has been completed.

Apologies I missed the screenshot, I see that you are trying to upload to the node without doing a get on it.

Could you please try adding the following statements before upload to ensure that node object has all the information from the slice?

s1 = slice.get_node(name="s1")  
s3 = slice.get_node(name="s3")

The above statements should be added after the cell which does a get_slice().

Also regarding the failed VM: h2 – unfortunately it is again because of disk un-availability. s2 and h2 are both requested on MICH and each VM is requesting 500G. Based on current allocation of MICH, only one can be provisioned.

This is because of a known issue: availability discrepancy between software and infrastructure. We are working on the plans to resolve this, until then if possible request VMs with smaller disks.

Thanks,
Komal

Hi Nagmat,

You have 4 active slices:

Slice Name: mri_ded3 Slice ID: d54fd501-ca14-49ce-b217-50c593bd0927 Project ID: 527832fc-c273-4254-b988-16e5c2923bf9 Project Name: in-network caching

Slice Name: mri1 Slice ID: 6ce8648d-26a9-47b8-8349-4e3e724085a0 Project ID: 527832fc-c273-4254-b988-16e5c2923bf9 Project Name: in-network caching

Slice Name: mri3 Slice ID: fa527279-b9bb-4dac-bb68-7a46b63c8ad1 Project ID: 527832fc-c273-4254-b988-16e5c2923bf9 Project Name: in-network caching

Slice Name: Nagm_P4Test01 Slice ID: 140247fe-cb45-47da-a797-dca5592487dd Project ID: 527832fc-c273-4254-b988-16e5c2923bf9 Project Name: in-network caching

The last slice Nagm_P4Test01 has two VM slivers on FIU and the VM slivers are in ActiveTicketed state – which means a pending Renew. We have been observing network issues with FIU and working to resolve that since yesterday. FIU was moved to maintenance as well. I do see management IPs for these VMs but it is possible that they are not accessible because of the network issue.

All other slices have all the VMs and Networks in Active state. If you are observing failure with these slices, please do a slice = fablib.get_slice(slice_name) and then try to upload the file.

Thanks,
Komal

Thank you Paul!

@Nagmat,
Could you please share the slice id for your slice?

Thanks,
Komal

Hi Nagmat,

I looked at your slice and the error reported above, your slice is requesting more than one VM on FIU and they are being allocated to fiu-w3.fabric-testbed.net. All the VMs are of the flavor: fabric.c8.m16.d500. Current disk availability on fiu-w3.fabric-testbed.net can only accomodate one such VM so all others fail.

We do have known discrepancy in the disk availability between the software and the infrastructure. We have plans to address that soon. Could you please use a different site instead of FIU for now?

Appreciate your feedback!

Thanks,
Komal

Maintenance is complete.

[Komal Thareja]

Thank you for sharing this! I would clean this up from the backend and would work on fixing this bug. Appreciate your feedback.

[Komal Thareja]

Maintenance has been lifted, testbed is open for use.
