Large Files

Starting with 2.6, the Solaris release supports files that are over 2 Gbytes. By default, UFS file systems are mounted with the -largefiles option to support the new functionality. Previous releases cannot handle files of this size. See "How to Disable Large Files on an NFS Server" for instructions.

No changes need to occur on a Solaris 2.6 NFS client to be able to access a large file, if the file system on the server is mounted with the -largefiles option. However, not all 2.6 commands can handle these large files. See largefile(5) for a list of the commands that can handle the large files. Clients that cannot support the NFS version 3 protocol with the large file extensions cannot access any large files. Although clients running the Solaris 2.5 release can use the NFS version 3 protocol, large file support was not included in that release.
