Re: Samba 2.0 as Windows PDC ?

When LDAP support is available it should help the account synchronization problem greatly. We are planning to provide that in the Win2000 timeframe.

RE: Tape Robots and "autoloading".
by Genrich, James R 28 Jan '99

28 Jan '99

Steve & Others, There are a few questions to be answered from the previous information. What is the OS being run on the F630? Is the Q2/15 an Autoloader of Robot version. Based upon a few assumptions there are three options. 1. If cost is the major consideration for using the Dump command as opposed to Backup Software there are a couple of options. First, you can use the control panel on a 9730 to mount drives to certain drives ( I am not sure if this is available in the Q2/15). This is not very automated since an individual will have to be present to use the control panel for mounts and unmounts. Secondly, you could write a script to do this, however this will be time consuming and it is reinventing the wheel (ie backup software is already written and tested) 2. To be able to perform simultaneous backup of 2 or more servers a backup software can be used along with STK ACSLS software (This software simply controls the robot and shares it between multiple servers or multiple backup packages). ACSLS needs a stand alone SUN or IBM box to run on (Sparc 10 or Small AIX server) for UNIX and needs Libattach software from STK if NT is involved. 3. Backup software can be installed on one of the server and the additional servers can be backed up over the network simultaneously using multiplexing capabilities common in most backup software. Based upon the current information these are the possible solutions.

For now that won't work because a symlink can't be followed out of a share (for security reasons). We're working on a way to get around that restriction. Mark Muhlestein -- mmm(a)netapp.com

quotas not working on clients
by George Kahler 28 Jan '99

28 Jan '99

Quota (quota [ -v ] [ username ] on all of our client machines stopped reporting user's disk quota. The problem was reported to NetApp but the answer I got back was that they were able to reproduce the 'problem' and that it works as designed. :-( Here is the background. At our university we have two toasters. A F520 and a F330 (Data ONTAP 4.3.3) that are part of a complex of machines used for providing electronic mail for staff and students (nfs). There are about 40,000+ accounts. The F330 used to contain the spool and the F520 contained two home directories (quota trees), one for staff and the other for students. Quota for spool (F330) were none. Quota for the individual home directories were set. The /etc/quotas file looked something like this /home_sta tree 39G /home_stu tree 20G # /home_sta/j/joe user 40M .. /home_stu/a/stud1 user 5M /home_stu/z/stud99 user 6M .. For performance reasons the spool was migrated from the F330 to the F520 and the /home_stu directory was migrated from the F520 to the F330. The F330 has only the one quota tree, /home_stu, where quotas are still defined as shown above. The F520 has two quota trees, /spool and /home_sta, where we don't want any individual quotas for the spool, however, we do need individual quotas on the /home_sta directories. The new /etc/quotas file looks like this /spool tree 25G /home_sta tree 39G # /home_sta/j/joe user@home_sta 45M /home_sta/x/fred user@home_sta 90M ... Now, all of the client machines (SunOS, Solaris 2.6) stopped reporting any user quotas. The quotas ARE still being enforced by the toaster, however, when a user queries his/her quota they get back just the headings, % id uid=101(dummy) gid=277(employee) % pwd /home/sta/x/dummy % quota -v Disk quotas for dummy (uid 101): Filesystem usage quota limit timeleft files quota limit timeleft % If, on the other hand, your home directory is on the F330 which contains only the one quota tree, the quotas do get reported correctly. % id uid=195(dummy1) gid=202(mailuser) % pwd /home/stu/t/dummy1 % quota -v Disk quotas for dummy1 (uid 195): Filesystem usage quota limit timeleft files quota limit timeleft /home/stu 72 5120 5120 32 10240 10240 % Any help would be greatly appreciated and I apologize for the long and winded description of the problem.

RE: Samba 2.0 as Windows PDC ?
by Allison, Bridget 28 Jan '99

>Does anyone have any experience using Samba 2.0 as a PDC? I don't know of any filer customer using Samba's PDC functionality successfully with the filer. I do know that based on my periodic checks with the Samba team on just when it makes sense for us to sink our engineering time into making sure we work with a Samba PDC, it's too early to start that work right now. The PDC support is not production quality - that's the word from the Samba team rather than mine. So, we do intend to work with a Samba PDC, it's part of our plan and we're trying to make sure the Samba side is fully cooked before we start our integration work. In the meantime, if there are customers using it successfully they haven't told me. They certainly couldn't use it with the NTFS style security today - Samba 2.0 doesn't have any SIDS to return to the filer. Since that's the case today, I'm presuming your question is more around the user authentication per se - just one aspect of PDC functionality but the primary one Samba does right now. >Also, what products (like Samba 2.0), if any, are people using to >synchronize logins between Unix (NIS) and Windows (NT PDC), especially >in a mixed environment using NetApp filers. Keith suggested our one-way tool, the MS Services for Unix is another one-way tool. I've seen some discussion on this topic on one of the Samba mailing lists - I think it was the samba-ntdom list - just this past week or so. You might want to check out the archives http://us1.samba.org/samba/archives.html If you find something you'd recommend then please let me know - we'd be interested in finding something to recommend to customers.

multiple CIFS HOME directories?
by Daniel Quinlan 28 Jan '99

28 Jan '99

Is it possible to have multiple default shares for CIFS homes? I am running 5.1.2P2. For example, let's say I have two quota trees on a NetApp. One is /vol/vol0/home_eng and the other is /vol/vol0/home_finance. Let's say home_eng is exported via NFS (for engineers) and home_finance is not (because it contains sensitive information such as employee salaries). I want to allow people to access both via CIFS. It is assumed that there will not be any username collisions between the two hierarchies. So if there is a /home_eng/bob directory, there won't be a /home_finance/bob directory (and vice versa). Can what I am trying to accomplish be done? (People like being able to map \\filer\myname to a drive letter. They don't like having to do stuff like \\filer\something -> W:\ and then having to go to W:\myname.) Thanks. - Dan

>Is it possible to have multiple default shares for CIFS homes? Not at the moment, although some enhancements are currently being made in this area. For people who have UNIX though, there is a workaround. Here's the gig... The idea is that you create a single home directories directory and populate it with symbolic links to the real home directories which can be anywhere on the filer. So, if: options cifs.home_dir {/vol/vol0}/home and joe and bill have home directories in /vol/vol5/home, then from a UNIX client you can: % cd /filer/vol0/home % ln -s /vol/vol5/home/joe ./joe % ln -s /vol/vol5/home/bill ./bill and bill and joe will get to play on the autoshare world even though their home directories are not in the cifs.home_dir directory. You might be forgiven for thinking "What about the not-following-symlinks-out-of-a-share rule?". Well, this doesn't apply here because the symlink *is* the share. Also beware: % cd /filer/vol0/home % ln -s /filer/vol5/home/joe ./joe % ln -s /filer/vol5/home/bill ./bill won't do the job, because if you do this, you set the symlinks to match the NFS *clients* view of where the directories are, not the filer's view. You would then have to engage the /etc/symlink.translations mechanism to translate the symlinks betwixt views, and you probably don't want to get into that. Keith

Does anyone have any experience using Samba 2.0 as a PDC? Also, what products (like Samba 2.0), if any, are people using to synchronize logins between Unix (NIS) and Windows (NT PDC), especially in a mixed environment using NetApp filers. Thanks for any info or suggestions. - Dan
