Not clear to me from your post whether you will need to run a tool on windows to move the data around. If so, there is at least the windows ssh client called putty and a win32 port of tar http://gnuwin32.sourceforge.net/packages/tar.htm but I suppose that once you tar up the files, you can simply drag them into a share on the new server and untar them with the -p flag. Aha. Now I see you may have some issue mapping the old windows user to the new linux user uid. You can instead force user and group by manipulating the attributes of the enclosing directory. -- see the earlier thread "[Samba] See inherit user, need inherit group" -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/listinfo/samba
AW: AW: [Samba] Migration to Samba using external LDAP server(CLARIFICATION NEEDED)
Hello, thanks for your reply. I didn't know that I was not specific enough. Let me go into the details. Current infrastructure: 9 Windows 2003 servers acting as file and print servers and a little bit of databases. Target infrastructure: 1 Debian Cluster running Samba 1 Database Cluster running ADAM (LDAP) Our current test environment exists of: Debian Cluster running Samba 3.0.14 with 2.8GHz proc and 4GB RAM each node. We have implemented a samba.ldf file to ADAM to do the mapping between SID and UID/GID. Samba uses external LDAP user validation for active directory. If a user tries to connect to a share the samba server contacts the external LDAP server for user verification/validation. LDAP server contacts PDC to validate user and to get SID. LDAP server stores SID and new created UID/GID to have an user mapping from the SID to the UID/GID. The user connects to the share, and when he stores a file he gets a UID/GID from Debian/samba. So e.g. user with SID blablabla-blablabla-blablabla gets UID 8235 and GID 7234. This works fine right now. We have the mapping running and all works as expected. But now the problem which occurs is that we want to migrate all data to this new cluster. If we would copy the data with simple xcopy or robocopy using e.g. an admin account from the domain, then the files which will be created have which owner? Will the permissions still remain? Example: Windows server with file readme.txt: Permissions: Read for everyone, Full access for admin account, Full access for owner Samba server copied file with any tool to samba share: Permissions: ?? Our current understanding would be that if every user would copy his own files under his account to his share then the permission would remain. But we can not ask each person to copy his files to the new server and to the right folder. The next problem we have is if the permissions can be maintained what happens to the mapping? The reasons for our concerns are that we are using a user mapping on an external LDAP server. So if we use a specific user account to migrate the data and assuming that each file will have a SID which UID/GID will be allocated to this data? We do not understand how to accomplish what we need. We try to understand how this mapping for every user will be done using our external LDAP server creating the UID/GID on the Debian server. Is this description now clearer? Any additional information needed? Thanks for the feedback so far.

You speak of using an 'external ldap server' above, is your intent to move away from using ldap and do things just with samba tdb backend, or do you want to move away from using LDAP to map to Active Directory SID's and just use LDAP to store the account information in alltogther... OR are you simply talking about migrating data (the 1.2TB you spoke of above) from one server to another - in which case, ya might look into rsync. Either way, a little clearification could go a long way, and a clearer question always leads to a more concise answer. > - How can we create the appropriate mapping on the external LDAP > server to maintain the permissions? > > NO idea, whatsoever, as to what you are asking here, see answer above; mapping for what; file permission, user data, and what exactly is meant by 'external ldap server', is it not on your network?

This kinda makes me think you're using the Samba server as a back-end to store the files for a Windows server; why else others would have reccomended netapp is beyond me? Are you using samba to service the end users, or samba to service as a SAN-store of sorts to other windows servers in-turn servicing the end users? Too many questions and not enough details provided by you make it hard for anyone to help. Thanks in advance. Best regards, Pseudomizer My suggestion; re-post with: A) First, what exactly are you trying to accomplish; what are your long term goals? B) Secondly, tell us how you're doing it now, and what specifically you don't like or what doesn't work (well). C) Lastly, explain what you want us (the mailing list) to send back to you; what do you want us to explain or help with, or do, changes with samba/etc... Your question asking is good, but your method of asking provides us with just enough information to shake our heads and ask 'why, what-the, huh?
