Additional Information
Maximum file size for CIFS shares and NFS exports
- File sizes are also bound by the amount of physical disk space available on the filer, and the supported capacity on the controller
- Regardless of the version of ONTAP in use, some protocols support files only up to a certain size:
- NFSv2 has a maximum file size of 2 GB
- NFSv3 allows for 64-bit file offsets, which is larger than the WAFL 16 TB maximum
Note: To confirm via AutoSupport: NFS-SERVERS-BYNAME.XML -> Use 64 Bits for NFSv3 FSIDs and File IDs
- Microsoft NTFS has a 16 TB file size limit in Windows 2003
- CIFS protocol allows for 64-bit file offsets, but most likely the WAFL limit will be reached beforehand
- Certain client operating systems may also limit the file size they can access, regardless of protocol
- Creating a file larger then 16TB fails on 9.12.1P2
