This is due to the stateless nature of the protocol, the -server has no way of knowing whether the client is keeping a reference -to a file or not, and hence that file may be removed from the server's -cache. In that case there has to be a way to look up that object -using the inode number, otherwise an ESTALE error will be returned. - -1) low-level interface - -Filesystems need to implement special lookups for the names "." and -"..". The former may be requested on any inode, including -non-directories, while the latter is only requested for directories. -Otherwise these special lookups should behave identically to ordinary -lookups. - -2) high-level interface - -Because the high-level interface is path based, it is not possible to -delegate looking up by inode to the filesystem. - -To work around this, currently a "noforget" option is provided, which -makes the library remember nodes forever. This will make the NFS -server happy, but also results in an ever growing memory footprint for -the filesystem. For this reason if the filesystem is large (or the -memory is small), then this option is not recommended. |
