NSS provides the following changes in the May 2017 patch release:
NSS supports 64-bit IDs, which supports up to 8 trillion (8E12) ZIDs. However, NCP clients and other traditional applications can only work with 32-bit IDs, which support up to 4 billion (4E9) ZIDs. So NSS restricts ZIDs, and thus the number of files to the lower value.
Beginning with OES 11 SP2 (May 2017) and OES 11 SP3 (May 2017) patch, NCP gracefully handles the 64-bit ZID, which allows NSS to store up to 8 trillion files in a single volume. For more information, see ReZIDing Volumes in an NSS Pool in the OES 11 SP3: NSS File System Administration Guide for Linux.
IMPORTANT:When the NSS volume is mapped through AFP, the NSS files and folders with ZIDs greater than 32-bit are not listed because of Apple Filing Protocol (AFP) limitation. If the NSS volume is shared over AFP, we recommend not to enable the 64-bit ZID option. However, if the NSS volume is shared over CIFS, NCP or both, the 64-bit ZID feature works fine with a minor limitation in salvage sub-system only for NCP. For more information on NCP limitation, see Salvaging and Purging of NSS Files or Folders in the OES 11 SP3: NCP Server for Linux Administration Guide.
