[Gluster-devel] File Inconsistency

[Ben Mok]

Hi All,

 

I am using 4 server nodes, afr + unify , glusterfs 1.3 .12 . I found that
the content of file are no consistency when I did failover testing. Time
zone of nodes are sync.  

My testing as below:

 

1. Create a file on client side 

   $echo aaaaaa > file  

2. Stop server 1

3. edit file 

   $echo a > file

4. Start server 1

5. Cat file on client side

  Result : 

a 

6. Cat file on server 1  

  Result :

  a

  aaaa  

7. Cat file on server 2 

  Result:

  a

 

The symptom can repeat easily, do you know what's problem ? Thx a lot 

Ben
