I have the same issue as ticket "Mount for shifter on NERSC #231". In that ticket, the solution was the following:
"You need to precreate the mount point in the image. So just add a RUN mkdir /your/mount/path. I feel like this check is to strict so I’m going to keep this open and see if we can allow this."
However, this is not possible in my case. For example, I'm trying to run cromwell (workflow engine) on cori. Cromwell will automatically create the mount points dynamically so the user doesn't know what they will be ahead of time. An example command is
shifter --image=jfroula/jaws-blastplus:1.0.16 -V /global/cscratch1/sd/jfroula/JAWS/jaws-blastplus/RunOnMac/cromwell-executions/runblastplus_sub/7dbb416c-c861-403b-8f5d-d83163751a57/call-shard:/cromwell-executions/runblastplus_sub/7dbb416c-c861-403b-8f5d-d83163751a57/call-shard

In this example, I don't have a /data directory in the container so
# this works
shifter --image=ubuntu:16.04 -V $(pwd):/data
# but this doesn't (adding slash to data)
shifter --image=ubuntu:16.04 -V $(pwd):/data/

I found a workaround for this issue. In the Cromwell config file, I can assign the variable dockerRoot to where to Cromwell server will be running. This insures that the mount point within the container exists.
