slice = fablib.get_slice(slice_name)
node = slice.get_node(node_name)
node.os_reboot()

This piece of code generated this error. Now that it’s live, I can access this node. Thank you very much, Komal.

Thank you very much, Komal, you are always a big help while working with fabric. I am not sure, but maybe overloading tasks on GPUs might have caused it crashed and then, when we reboot, it vanish the network interface settings and detaches PCI devices.

It’s working pretty much well, thank you so much 😊 .

[Ajay Kumar]

Yes I did! but anyways, it started working, I guess there was some time constraint issue that time. Its working perfectly now.

Is there issues going with fabric Jupyter lab to create cluster right now? It was working pretty fine yesterday.

[Ajay Kumar]

Thank you very much, now it works fine, double hands up for your help, Komal.

Thank you so much, Komal, it worked for me.

Following on that, I noticed my interface (enp9s0) is not found, earlier it was there. I have used this interface to connect with other nodes in the cluster. Could you please help me to make it UP again?

Does anyone know, how to reboot a node even if ping and ssh not working to that same node?
