we have two oes Linux server running in a cluster

I want to share the nss volumes via samba.

i configured everything like described in the manuals.

On the first server where we have an volume called APP everthing works fine
on the second server we have an volume called DATA

first smb.conf
...
[APPNSS]
comment = Samba nss Zugriff
path = /media/nss/APP
browseable = Yes
read only = No
inherit acls = Yes
...

second smb.conf
...
[DATANSS]
comment = Samba nss Zugriff
path = /media/nss/DATA
browseable = Yes
read only = No
inherit acls = Yes
...

an access from an workstation the samba server could not find the volume

log.smbd
...
[2008/03/04 14:02:05, 0] smbd/service.c:make_connection_snum(633)
'/media/nss/DATA' does not exist or is not a directory, when connecting to [DATANSS]
....

Do you have any hints for me .

Thanks Thomas
