Steve,
To answer your questions about the bug I am seeing, I have compiled the
following. Look below, there is a significant difference in the client
side file permissions when cifs is used to mount the volume and when
smbfs is used. This is fully repeatable and the listings below did not
require system reboot, just different -t (cifs|smbfs) switches on the
mount.
1. I first saw the problem after upgrading a single client to 8.04 (AMD
64 bit). The server was then Xubuntu 7.10 with standard up-to-date samba
packages. This was then upgraded to 8.04 Xubuntu and the problem
remained.
2. The definition of the share is:
[TASData]
comment = TasBooks Data Files
path = /raiddisk/shared/tasbooks
valid users = @accounts
force group = accounts
read only = No
acl check permissions = No
directory mask = 0775
force directory mode = 00
browseable = No
3. The fstab is:
//olympus/tasdata /home/tony/tasdata cifs
credentials=/etc/samba/tw.pw,uid=1000,gid=1000,auto,rw 0 0
4. The server side listing is:
-rw-rw-r-- 1 tony accounts 3584 2008-04-28 11:56 mt1pmt.b
-rw-rw-r-- 1 tony accounts 3584 2008-04-28 11:56 mt2pmt.b
-rw-rw-r-- 1 tony accounts 3584 2008-04-28 11:56 mt3pmt.b
-rw-rw-r-- 1 tony accounts 3072 2008-04-28 11:56 mt4pmt.b
-rw-rw-r-- 1 tony accounts 3072 2008-04-28 11:56 mtabacs.b
-rw-rw-r-- 1 tony accounts 6144 2008-04-28 11:56 mtabank.b
-rw-rw-r-- 1 tony accounts 3072 2008-04-28 11:56 mtabia.b
-rw-rw-r-- 1 tony accounts 26624 2008-04-28 11:56 mtabud.b
-rw-rw-r-- 1 tony accounts 3072 2008-04-28 11:56 mtacadv.b
-rw-rw-r-- 1 tony accounts 7680 2008-05-05 14:43 mtaccat.b
-rw-rw-r-- 1 tony accounts 10240 2008-05-15 22:13 mtacent.b
<truncated - all other files have the same permissions>
5. The client side listing (when mounted as CIFS) is:
-rw-rw-r-- 1 tony tony 3584 2008-04-28 11:56 mt1pmt.b
-rw-rw-r-- 1 tony tony 3584 2008-04-28 11:56 mt2pmt.b
-rw-rw-r-- 1 tony tony 3584 2008-04-28 11:56 mt3pmt.b
-rw-rw-r-- 1 tony tony 3072 2008-04-28 11:56 mt4pmt.b
-rw-rw-r-- 1 tony tony 3072 2008-04-28 11:56 mtabacs.b
-rw-rw-r-- 1 tony tony 6144 2008-04-28 11:56 mtabank.b
-rw-rw-r-- 1 tony tony 3072 2008-04-28 11:56 mtabia.b
-rw-rw-r-- 1 tony tony 26624 2008-04-28 11:56 mtabud.b
-rw-rw-r-- 1 tony tony 3072 2008-04-28 11:56 mtacadv.b
-rw-rw-r-- 1 tony tony 7680 2008-05-05 14:43 mtaccat.b
-rw-rw-r-- 1 tony tony 10240 2008-05-15 22:13 mtacent.b
The client listing when mounted as smbfs is:
-rwxr-xr-x 1 tony tony 3584 2008-04-28 11:56 mt1pmt.b
-rwxr-xr-x 1 tony tony 3584 2008-04-28 11:56 mt2pmt.b
-rwxr-xr-x 1 tony tony 3584 2008-04-28 11:56 mt3pmt.b
-rwxr-xr-x 1 tony tony 3072 2008-04-28 11:56 mt4pmt.b
-rwxr-xr-x 1 tony tony 3072 2008-04-28 11:56 mtabacs.b
-rwxr-xr-x 1 tony tony 6144 2008-04-28 11:56 mtabank.b
-rwxr-xr-x 1 tony tony 3072 2008-04-28 11:56 mtabia.b
-rwxr-xr-x 1 tony tony 26624 2008-04-28 11:56 mtabud.b
-rwxr-xr-x 1 tony tony 3072 2008-04-28 11:56 mtacadv.b
-rwxr-xr-x 1 tony tony 7680 2008-05-05 14:43 mtaccat.b
-rwxr-xr-x 1 tony tony 10240 2008-05-15 22:13 mtacent.b
7. The underlying problem is when the closed source TAS Books program tries to
open its accounts database. It reports that the database is being used by a
maintenance utility. However, you get exactly the same error message if the
share is not mounted - so that is not really very useful. I have no problem
opening any of these files in a text editor (under cifs), or in saving them, so
this is not a simple permissions problem. While it is not really possible to
know what the program is doing, I know that it will try and gain exclusive
access to the files and my guess is that it is failing at this point.
One thing is certain, now that I have compiled in the smbfs module from
samba 3.0.28a, if I mount the share as smbfs, the program works, if I
mount it as cifs, it doesn't.
