[Gluster-devel] Can't get afr to work

[Daniel van Ham Colchete]

James,

I'm not a Gluster developer but I think I know what the problem is.

To test my hypothesis, try a telnet at 127.0.0.1:6997. If I'm right it won't
work.

The cause of the problem is that the volume name for both servers is the
same and this shouldn't be right. Try changing the second server volume name
from 'server' to 'server2'. It's not necessary to change anything else.

Your gluster mountpoint works because AFR will work even if one of the
servers is down.

Tell-me what you found.

Best regards,
Daniel Colchete
