Hi,

I 1.4.0pre5 doesn't seem to work for me at all.

When I try to ls the share, I get broken directory entries. This is the 
sort of thing ls returns for my home directory:

?---------  ? ?                ?             ?            ? gordan

instead of:

drwxr-x--- 70 gordan           gordan      4096 Nov  3 01:22 gordan

This is what ends up in the log:
2008-11-02 13:42:02 C [posix.c:2749:ensure_file_type] home-store: stat 
failed while trying to make sure entry /gluster/home/gordan/.
wine is a directory: No such file or directory
2008-11-02 13:42:02 E [afr_self_heal.c:123:afr_lds_setdents_cbk] home: 
op_ret=-1 op_errno=2
2008-11-02 13:42:02 E [fuse-bridge.c:398:fuse_entry_cbk] glusterfs-fuse: 
50: LOOKUP() /gordan => -1 (Input/output error)

The .wine directory it is complaining about is actually a symling to a 
directory on a local file system.

The above issue exhibits itself on both of the nodes when the 2nd node 
has the gluster daemon up and running. But when the 2nd node is removed 
and only one node remains, it starts working OK again.
