Steps to reproduce the behavior

  1. Create two EFS shares (one regular and other with max_io)
  2. Install cloudstor:aws plugin using this command (replace de parameters with the efs share ids): 
    docker plugin install \
--alias cloudstor:aws \
--grant-all-permissions docker4x/cloudstor:18.03.1-ce-aws1 \
CLOUD_PLATFORM=AWS \
AWS_REGION=<your_aws_region> \
EFS_SUPPORTED=1 \
EFS_ID_REGULAR=<efs id from the regular efs share> \
EFS_ID_MAXIO=<efs id from the max io efs share> \
AWS_STACK_ID=nostack \
DEBUG=1
  3. Check the mount point options by issuing a mount |grep nfs. The result will be similar to the following: 
    <efs id from the regular efs share>.efs.us-east-1.amazonaws.com:/ on /var/lib/docker/plugins/bffee80f7e6b251c84eb05dfa68d9cddca807c795a5e69badbff9f8f2d6296b9/propagated-mount/efs/reg type nfs4 (rw,relatime,vers=4.1,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,clientaddr=172.31.0.104,local_lock=none,addr=172.31.0.53)
<efs id from the max io efs share>.efs.us-east-1.amazonaws.com:/ on /var/lib/docker/plugins/bffee80f7e6b251c84eb05dfa68d9cddca807c795a5e69badbff9f8f2d6296b9/propagated-mount/efs/max type nfs4 (rw,relatime,vers=4.1,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,clientaddr=172.31.0.104,local_lock=none,addr=172.31.0.94)
