EFS NFS Mount - Input/output error

[anthonyeden]

I have successfully connected to an AWS EFS mount. However, after a short period any attempt to use the mount reports a generic "Input/output error".

I connect successfully using this command:

fuse-nfs -a -n "nfs://1.2.3.4/?version=4" -m /data/

I cannot work out how to debug this or get a more meaningful error.

Using killall fuse-nfs stops the error and returns an empty directory again.

I have built this on Ubuntu 20.04 using the supplied instructions in the README file.
