Hi @grainpad15 , sorry for the late response. Yes we only give out 100GB disk for each job, so you can't mount data that's larger than this size. We are experimenting with 200GB disk for workspaces, but we haven't decided on whether to keep this configuration or keep it the same as job (100GB).
I have added a ticket to track this in our internal ticket system. We will improve the error message to make it less confusing.
