In Unity 5.5, File System (FS) access can be provided using a Network File System (NFS) mount using NFSv3 or NFSv4 file sharing protocols. This is typically done for Logical Unity Numbers (LUN) and NFS datastores with specific mounting parameters and then scripted for various groups of hosts. A directory is created for the mount point when mounting file shares using NFSv4.2. If the directory security label (sec_label) parameter has no data assigned to it, the Unity Service Processors (SP) can panic and reboot unexpectedly.

When a storage pool's usage exceeds its high water mark, the automatic snapshot deletion (auto delete) feature pauses. Although it tries to delete snapshots to free up space, it may not be enough to bring the pool's usage below the threshold. As a result, the auto delete function remains paused, displaying an error message, until you manually restart it. Once reenabled, the auto delete feature resumes attempting to delete snapshots and reduce pool consumption.
