Slice won’t stabilize

[Vaiden Logan]

FABlib Version: 1.6.2

slice ID: 61c1d373-b3b6-472f-a34a-3dd6dac8c809

One of my nodes was deleted during fabric maintenance, so I tried to add it back. I tried to use the same name, but Fabric rejected that because names have to be unique. After that, I changed the names of everything, but I got the following error on submissions:

Failed to submit slice: Status.FAILURE, (500)
Reason: INTERNAL SERVER ERROR
HTTP response headers: HTTPHeaderDict({'Server': 'nginx/1.21.6', 'Date': 'Sat, 03 Feb 2024 22:38:34 GMT', 'Content-Type': 'text/html; charset=utf-8', 'Content-Length': '274', 'Connection': 'keep-alive', 'Access-Control-Allow-Credentials': 'true', 'Access-Control-Allow-Headers': 'DNT, User-Agent, X-Requested-With, If-Modified-Since, Cache-Control, Content-Type, Range, Authorization', 'Access-Control-Allow-Methods': 'GET, POST, PUT, PATCH, DELETE, OPTIONS', 'Access-Control-Allow-Origin': '*', 'Access-Control-Expose-Headers': 'Content-Length, Content-Range, X-Error', 'X-Error': 'Unable to modify Slice# 61c1d373-b3b6-472f-a34a-3dd6dac8c809 that is not yet stable, try again later'})

I decided to wait a little over 24 hours, but on submission of the modified slice I had the same output.

I just got my slice and nodes so I could run commands on them, but on running node.execute(‘echo hi’) I was given this error:

AuthenticationException: Authentication failed.

You slice is in state ModifyError For any further modifications to your slice, you need to run the following commands:

slice=fablib.get_slice(name=slice_name)

slice.modify_accept()

Regarding the Authentication Error. Please check if you Bastion key has expired and SSH keys are setup properly. You can use the notebook config_and_validate.ipynb to update/validate SSH keys and your config.

Slice state: ModifyError

Also, looking at /tmp/fablib/fablib.log would provide more information for the failure cause for Authentication error.

Thanks,

Hey @Komal,

I think the issue may be slightly larger. I ran
slice=fablib.get_slice(name=slice_name)

slice.modify_accept() like you suggested, but upon submitting a new modification I got another modify error. I included an image of what I saw.
