a.k.a NT_STATUS_UNSUCCESSFUL

So instead of NT_STATUS_INVALID_INFO_CLASS NetApp Filer can return the
generic error NT_STATUS_UNSUCCESSFUL.

Well then the fix is the following:

    public long getDiskFreeSpace() throws SmbException {
        if( getType() == TYPE_SHARE || type == TYPE_FILESYSTEM ) {
            int level = Trans2QueryFSInformationResponse.SMB_FS_FULL_SIZE_INFORMATION;
            try {
                return queryFSInformation(level);
            } catch( SmbException ex ) {
				switch (ex.getNtStatus()) {
					case NtStatus.NT_STATUS_INVALID_INFO_CLASS:
					case NtStatus.NT_STATUS_UNSUCCESSFUL: // NetApp Filer
                    	// SMB_FS_FULL_SIZE_INFORMATION not supported by the server. 
                    	level = Trans2QueryFSInformationResponse.SMB_INFO_ALLOCATION;
                    	return queryFSInformation(level);
                }
                throw ex;
            }
        }
        return 0L;
    }

This has been added to The List.
