Hello Cloudlab,

I was trying to start some experiments, but I encountered node boot failures.

On my first attempt, three nodes failed. I restarted the experiment, but on the second attempt, still two nodes failed.

First attempt is [Node: c240g5-110229] [Node: c240g5-110211] failed.

Could you help me determine what might be causing this issue?

--- experiment info ---
Nodes:
  [Node: c240g5-110229] [Node: c240g5-110203]
in urn:publicid:IDN+emulab.net:dynamicgpu+slice+klin-310668 failed.

Hi Kevin, apologies for the delay in response.

Looks like those nodes went out of service after you tried to instantiate on them, which usually indicates some kind of hardware problem with the servers.  We will get somebody to look at those servers, thanks for the heads-up and sorry for the inconvenience.

Best,
 - Aleks
