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
