MacOS may corrupt file data when writing to SMB2 network attached storage. In some cases, it may be desireable to serve different storage devices from separate ExpeDat hosts.
To control which devices users can access, set RestrictHome and use AllowPath to limit access to approved devices. See Tech Note 0029 for guidance on tuning NAS devices for high performance.īe wary of allowing users to access arbitrary network mounts (such as with UNC paths). For best performance, ensure that all storage devices are capable of consistently reading and writing data faster than the network. This is especially noticeable when writing to network attached storage systems of differing capabilities. In extreme cases, a hung storage device may hang the entire host operating system. When writing files to multiple storage devices, poor performance by one storage device may degrade performance for other devices. Network attached storage mounts may enforce their own authentication and access controls which may restrict access by the ExpeDat server. See the Performance chapter for general guidance on storage performance. If you must use NAS, see Tech Note 0029 for guidance on tuning NAS devices for high performance. Transferring files which are stored on NAS devices may be severely limited by the speed of the legacy protocols used by those devices.
