Symbolic Links (Soft and Hard)

Does Isilon support Unix Extensions for mounting CIFS shares on Linux?

Unfortunately not. Isilon switched from using Samba to a product called Likewise a year or two back. Likewise does not support Unix Extensions.

Does Isilon support symbolic links over CIFS?

Isilon does not support Windows symbolic links over CIFS.


  • does not support the POSIX Extensions required for use of soft links on Linux systems via CIFS (e.g. ln -s over CIFS will fail);
  • but hard links are supported.

A request for enhancement has already been made (February 2013) to EMC.

Does Isilon support symbolic links over NFS?

Yes, both hard and soft links are supported.
