Hmm, interesting. If the problem is only byte range locking what about 'translating' byte range locking into entire file locking? Do you know if there is already some testing tool to stress test unix locking? If not, shouldn't be difficult to write it.

You should install Samba on the NFS server, and possibly redirect your users using MS-DFS. For the moment that would be a solution. Acctualy nfs is running on an rather old (and slow) linux server, there I could install (and configure) samba. But this server was only reactivated because of some problems with our NAS. The NAS crashed several times when we used samba and nfs (nfs3) at the same time. Acctually we do not knowwhy it crashed, but it seems safer to use only nfs (x)or smb.

[Samba] Samba on Debian with shares on nfs-filesystem
Hello, Actually I have some troubels concerning samba (3.0.24) on debian (4.0): I would like to have some samba-shares on a nfs-filesystem. NFS works fine for the Linux clients and the Linux server. The nfs filesystem is mounted from an other server on /home. The next step is to set up samba to have some shares on the nfs Filesystem (/home/$LOGIN, anonymized configuration attached). Connecting to the samba shares works for Linux and Windows clients fine. Downloading files also does fine. Copying files from the local filesystem to the samba-shares works fine for Linux-clients (via smb!), but not for Windows clients: Copying files from Windows 2k to the samba share results in the following error message: foo kann nicht kopiert werden: Der Prozess kann nicht auf die Datei zugreifen, da ein anderer Prozess einen Teil der Datei gesperrt hat. (In english something like: Can't copy foo: process cannot acces the file as some other file is locking a part of the file.) But there is no other process accessing this file. Applications can save their files to the samba shares. These files have the filesized as wished by the windows-application but are filled with zeros. According to http://www.debianforum.de/forum/viewtopic.php?t=83647 I am not alone with this problem. Further: The member of that forum wrote that he had compiled several samba verisons by himself on debian 4.0/etch: The problem did not occur with samba 3.0.22 and 3.0.23. But the problem occured also on the self-compiled samba 3.0.24. He also compiled several versions of samba on debian 3.1/sarge: There the problem did not occour with any version of samba. I have tried to have these samba-shares on nfs3 and nfs4 filesystems. The choice of nfs3 or nfs4 doesn't affect the problem. So my question is how it is possible to use samba on debian 4.0 in such a configuration. I would prefer to use official debian packages or the packges from the samba.org-webpage (but at the moment there are no Debianpackages for Debian 4.0 on the samba Webpage). I could compile samba by myself, but I would prefer some other solution. Thanks and best regards Thomas PS: As I don't know wheter it is a samba issue or only a debian issue, I crosspost to both mailinglists. -- Thomas Flaig mailto: [EMAIL PROTECTED] [global] workgroup = $WORKGROUPNAME server string = %h server interfaces = $IPs bind interfaces only = Yes obey pam restrictions = Yes passdb backend = tdbsam pam password change = Yes passwd program = /usr/bin/passwd %u passwd chat = *Enter\snew\sUNIX\spassword:* %n\n *Retype\snew\sUNIX\spassword:* %n\n *password\supdated\ssuccessfully* . log level = 2 syslog = 0 log file = /var/log/samba/log.%m max log size = 1000 printcap name = cups logon path = \\$HOSTNAME\%U\profile logon drive = H: logon home = \\$HOSTNAME\%U domain logons = Yes os level = 240 preferred master = Yes domain master = Yes dns proxy = No wins support = Yes panic action = /usr/share/samba/panic-action %d invalid users = root printing = cups print command = lpq command = %p lprm command = [homes] comment = Home Directories path = /home/%S/ valid users = %S read only = No create mask = 0751 directory mask = 0751 browseable = No [printers] comment = All Printers path = /var/spool/samba create mask = 0700 printable = Yes browseable = No [print$] comment = Printer Drivers path = /var/lib/samba/printers write list = root, @lpadmin -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/listinfo/samba

One potential workaround (no guarantees!) is to say posix locking = no on the relevant shares. can you give more insights why it doesn't work? In my previous group at university users can call vmware to get windows running on their linux desktops. Samba is used to provide roaming profiles and access to the users home directory. The hole setup is a bit tricky, but samba works as full domain controller, but is started as a user process as the user who also runs vmware. So no root rights, etc. This also makes it impossible to run samba on the server, but smbd MUST be run on this very client system to serve the nfs share. On debian Sarge samba-3.0.22 worked fine, also with posix locking = no, on Etch windows has problems to store cached data on the end of the session unless posix locking = no is set.
