Gluster users - May 2010 - DHT translator problem

Hello,

I am trying to configure a volume using DHT, however after I mount it, 
the mount point looks rather strange and when I try to do 'ls' on it I
get:

ls: /mnt/gtest: Stale NFS file handle

I can create files and dirs in the mount point, I can list them but I 
cant list the mount point itself.

Example:

the folume is mounted on /mnt/gtest

[root at storage2]# ls -l /mnt/

?--------- ? ?    ?        ?            ? gtest

If I try to list the mountpoint:
[root at storage2 ~]# ls -l /mnt/gtest
ls: /mnt/gtest: Stale NFS file handle

Can anyone please help me fix this.

Here is the systeminfo:

Did you try to umount and mount it again? From my tests with gluster 
when I start server and first time mount the share it behaves like you 
said, but if re-mount it, it works. This is not a solution, just what I 
found.

We need the logs to figure out the exact problem. Please run the 
glusterfs command while mounting through FUSE with the following command 
line option:

glusterfs -f <your-dht-volfile> -L TRACE -l /tmp/dhtlog /mnt/gtest

Then perform the same operations and email us the dhtlog file, and we'll 
see whats going on.

Thanks
