Jupyter Notebook is using sqlite database to store the info. Unless you
explicitly force Jupyter to create the database on the scratch directory
the database is stored on the NFS share. There is nothing worse one can
do in terms of data consistency than put a database or a private Git
repo (talking about the server) onto the NFS. The datebase was left in
inconsistent state after the file server was rebooted. You have to clear
it and possibly recreate the database to be able to use Jupyter
Notebook. 

Best,
