I an encountering an issue trying to mount a folder from a Windows 10 Pro 64Bit host in to a container built from a Debian base image. What’s strange is that it works fine on my desktop. The problem only occurs on my laptop. I’ve racked my brain and checked lots of things but I can’t discern what difference there might be in the two setups that means it works on one and not the other.
On my desktop, if I mount the folder at the point that I run the container using the -v flag then within the container and I cd in to the location of the mount and list files but if I try to cat or vi one of the files I get an “Operations not supported” message. I think this is making the files unusable by processes in the container that I need to work. On my desktop there is no such problem, everything works and I can cat and vi the files too without complaint.
Any ideas?
Here is the output from mount run inside my container in case that provides any useful information:
