CentOS 5.5 glusterfs "Transport endpoint is not connected"

Dear Community,

Still have trouble with glusterfs! Wanted to replicate over two storage servers. But after I mounted the volume I get the following error:

Code:

"df: `/mnt': Transport endpoint is not connected"

Also ls or other things are not working ... I have this behavior if I try to mount the fs from a third server or one of the glusterfs servers!
Hope you can help me, I also installed the glusterfs-fuse for CentOS, fuse is also loaded:

Code:

[root@gluster00 ~]# lsmod | grep fuse
fuse                   83057  2
