    • GPUs on nodes any taint other than the supported 'nvidia.com/gpu' taint cannot be selected when creating a notebook server. To avoid this issue, use only the nvidia.com/gpu taint on GPU nodes used with OpenShift Data Science.

      Description of problem:

      GPU drop-down is not showing up. I thought maybe someone was already using the GPU. that was not the case. 

      I have one GPU node, and there was no Notebook pods on it. 

      I have a feeling I might know why. Hold on. I need to test my theory. 

      So, yeah. The difference is that I usually add a Taint to my nodes called "notebooksonly". I did add it to the GPU node, because:

      A) that node has no taint by default

      B) I had noticed random pods landing on it and hogging it for nothing

      However, as soon as I add the taint, a few minutes later, the drop down disappears. 

      When I remove the taint, the drop-down re-appears. 


      Prerequisites (if any, like setup, operators/versions):

      RHODS + GPU

      Steps to Reproduce

      1. add a taint called "notebooksonly" to the GPU machine pool. 
      2. wait 5 minutes

      Actual results:

      drop down no longer shows up in JupyterHub. 

      Expected results:

      I'd expect it to still show. 

      Reproducibility (Always/Intermittent/Only Once):
