The great god good
The younger brother in a recent study KFS
The code is as follows:

 
String strMetaHostName="localhost"; 
String strDir="/MNT/test"; 
String strFileName=strDir + "/1"; 
KfsClientPtr pKfsClient=getKfsClientFactory () - & gt; GetClient (strMetaHostName, 20000); 
Int ierr=pKfsClient - & gt; The file.mkdirs (strDir c_str ()); 
If (0!=ierr) 
{
Printf (" the file.mkdirs failed> Errno=% d \ n ", ierr); 
} 
The else 
{
Printf (" the file.mkdirs success \ n "); 
Int _fd=pKfsClient - & gt; Open (strFileName. C_str (), O_CREAT | O_RDWR); 
If (_fd & lt; 0) 
{
Printf (" create | open file [% s] failed \ n ", strFileName. C_str ()); 
} 
The else 
{
String strContent="test write"; 
Ssize_t ret=pKfsClient - & gt; Write (_fd, strContent c_str (), strContent. The length ()); 
If (ret & lt; 0) 
{
Printf (" Unable to write \ n "); 
} 
The else 
{
Printf (" Write success \ n "); 
} 
} 
} 

Background:
1. The existing two machines A and B are decorated in KFS
2. Metaserver KFS and chunkserver are on the same machine
3. The above code on A machine

Question:
1. When strMetaServer="localhost", create the directory and file for write operations are no problem
2. When strMetaServer=B: hostname (machine B IP), create a directory that's no problem, but returned the following error when call Write

 
The 01-10-2014 11:04:38. 003 INFO - (KfsClient. Cc: 2638) Unable to connect to any server for the size on fid: 271 
The 01-10-2014 11:04:38. 004 INFO - (KfsClient. Cc: 2043) Unable to get the size for the chunk 259; Error=9; The need to retry 

3. Check the machine B the metaserver chunkserver service discovery running

For the great god help to analysis what is the problem with
Thank you very much

Well, no one, under the roof

I think a problem is unlikely to code, and the greatly help analysis of what is wrong with the configuration of the
