hi, i have looked few month ago about the trouble of NFS disk and hardlinking files on it. i don't have the final answer but my guess is : look in the RFC http://www.ietf.org/rfc/rfc1813.txt?number=1813 then you can see : Because the NFS version 3 protocol is designed to be operating-system independent, it does not necessarily match the semantics of any existing system. Server implementations are expected to make a best effort at supporting the protocol. If a server cannot support a particular protocol procedure, it may return the error, NFS3ERR_NOTSUP, that indicates that the operation is not supported. For example, many operating systems do not support the notion of a hard link. A server that cannot support hard links should return NFS3ERR_NOTSUP in response to a LINK request. FSINFO describes the most commonly unsupported procedures in the properties bit map. Alternatively, a server may not natively support a given operation, but can emulate it in the NFS version 3 protocol implementation to provide greater functionality. so the first step in the answer is : The server OS does not handle hardlink (due to OS or physical partition disk) the NFS server answer reject the hardlinking operation. My guess in your case is that your snap 2200 is running on windows and does not support the feature. i have heard about SFU from Redmonds to solve this kind of trouble, using SFU you can do some NFS share on windows machine using ntfs file system and the nfs share support hard link but i have never use them and am not sur this way is usable on your appliance. (http://www.softpanorama.org/Unixification/SFU/index.shtml) but am sure that using hardlink on NFS disk is possible and is working (minus some bad implementations) since version 2. so at the epoq i decided to use iscsi and all is working perfectly. mna. ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
