Can anyone please tell me how to get the size of the NFS Export point at the client side if the export point is available? Is there any command / Java API available for the same?
Take a look at Lucas' answer here: How to find how much disk space is left using Java. If you pass the mount point on the NFS client in to the getTotalSpace() and/or getUsableSpace() methods on the File class, it should return the relevant information for that export.
