Hey Michael, Thanks for the quick response, I've been bashing my head against this for a while. Unfortunately restarting the docker daemon did not work for me. I can access the EFS from within docker using regular unix commands like `cp`, and `cat`, even with GDAL `VSIFOpenL` and `VSIFReadL`. However, `gdal.Open` will just hang without giving an error or returning.
I'm using the following mount command from amazon EFS if this helps debug anything: `sudo mount -t nfs4 -o nfsvers=4.1,rsize=1048576,wsize=1048576,hard,timeo=600,retrans=2 <fs-id>.efs.us-west-2.amazonaws.com:/ /mnt/efs` I'm glad that you have a working version of this though, this had worked for me in the past but I did not keep track of my versioning. What host os version, docker version and gdal version are you using? - Ouwen On Sun, Mar 18, 2018 at 2:31 AM Michael Smith <michael.smith.e...@gmail.com> wrote: > Have you restarted the docker daemon after mounting the EFS drive to the > local OS?
