[Samba] Troubles with dfs-linked root shares
Hi,
Im trying to set up a samba cluster (using RHCS) to hold students'
Home directories according to the following schema:
\\disc\personal
|
+--------------------+----------------------+
| | |
| | |
v v v
\\disc01\target \\disc02\target ... \\discXY\target
The service "disc" will only hold dfs links and act as a load balancer
to the services "disc01" to "discXY" that will hold real
user data.
The share "personal" on "disc" is configured as:
[personal]
path = /mnt/discdata000/personal/%U
msdfs root = true
and "target" share is configured on the remaining "discXY"
services as:
[target]
path = /mnt/discdataXYZ/personal/%U
DFS links are created as follows (users will be evenly hashed among
"discXY" "target" shares):
$ ls -l /mnt/discdata000/personal/villapla
lrwxrwxrwx 1 root root 19 Jun 30 12:53 /mnt/discdata000/personal/villapla
-> msdfs:disc01\target
But the samba server seems unable to handle such dfs root links (see
attached file "log-001.txt" for "disc" smbd logs):
$ smbclient -U villapla //disc/personal
Password:
Domain=[AUTH-SMB] OS=[Unix] Server=[Samba 3.0.33-3.7.el5]
tree connect failed: NT_STATUS_BAD_NETWORK_NAME
Avoiding the dfs root link by using this config for the "personal"
share:
[personal]
path = /mnt/discdata000/personal
msdfs root = true
works fine (see attached file "log-002.txt" for "disc" smbd
logs):
$ smbclient -U villapla //disc/personal/villapla
Password:
Domain=[AUTH-SMB] OS=[Unix] Server=[Samba 3.0.33-3.7.el5]
smb: \>
Those services are running on RHEL 5.3 with samba-3.0.33-3.7.el5.
Also tried the latest samba RPM from sernet (samba3-3.3.6-39.el5) and
got the same results.
Should dfs links for root shares work?
Best regards,
Juanjo
