Does cPanel support Network File Systems? Also known as NFS.
NFS is not supported for use on cPanel servers. This goes for your backups, home directory, or any other mount points on the server. Using NFS for any reason on cPanel servers could lead to a wide range of various issues that we would be unable to support.
Please see the following documentation for more information.
Note: We only develop and test cPanel & WHM on filesystems that support flock. Some network filesystems (for example, NFS) may require additional configuration in order to function properly. However, these configurations are difficult to implement successfully and we do not support them.
