ndmpcopy license
by Daniel Quinlan 30 Jan '99

30 Jan '99

Maybe someone at NetApp can answer this question... What are the copying/license terms for ndmpcopy? The source code is copyright Network Appliance and PDC, contains a few disclaimers, but no terms for source modification and copying. Maybe an Open Source license would be in order. - Dan

Using MORE than one narrow shelf on a single Wide Bus
by Weeks, Thomas 29 Jan '99

29 Jan '99

Hi all... Here's a question that I still have never got a straight answer on from anyone: Using a F230 server with two wide SCSI busses. I have a wide shelf on my 9b bus, and a narrow DEC-Shelf (with personality module) on my 9a bus. My Q is this: On my 9a bus(only); since the personality module allows you to set the beginning SCSI/Wide address of the narrow shelf on the wide bus, could one essentially run TWO narrow shelves on a wide bus? This would be done by setting the first narrow shelf to map narrow-SCSI ID's 0-6 to the wide-SCSI bus 0-6, and setting the personality module in the SECOND narrow shelf (on 9a) to superposition the second narrow-SCSI shelf's ID's 0-6 to the SCSI-wide bus ID's of 8-15? If SO... then I could buy a personality module for one of my extra narrow shelves lying around and use TWO narrow shelves on the 9a bus of our F230! If not.. I am thinking about ripping it all out and putting it on a Linux box running SW RAID and SAMBA. But I would really like to keep it set up on the NetApp box if possible. Anyone know for SURE if this can be done (the former.. not the latter). Thomas Weeks GTE SYSTEMS ENGINEER Testing-Integration Center "The Pit" Brooks AFB, DSN 240-5444

Used NetApps?
by Brian Marcotte 29 Jan '99

29 Jan '99

I'm looking into the possibility of buying used Filers from companies who resell used equipment, or directly from other end users. I've seen no mention of this idea on the list. Does anyone know of any such companies (or do you have a filer you'd like to sell me?) Thanks. -- - Brian

RE: multiple CIFS HOME directories?
by Hawley, Rob 29 Jan '99

29 Jan '99

The symlink feature works due to a quirk in the implementation. Home Dirs work by resolving the path <cifs.home_dir>/<user_name> using an internal NFS like operation. Since the operation is NFS like, it knows how to follow symlinks. As Keith said, we now have the root of a virtual share so we obey the NT security model from that point on. You can't follow the symlink in CIFS due to the current security restrictions on respecting share boundaries. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ > mailto: hawleyr(a)netapp.com <mailto:hawleyr@netapp.com> US Mail: Network Appliance Inc. > Phone: 408-367-3254 2770 San Tomas Expressway > FAX: 408-367-3451 Santa Clara, CA 95051 -----Original Message----- From: Graham Knight [mailto:grahamk@ast.lmco.com] Sent: Thursday, January 28, 1999 4:27 AM To: Keith Brown Cc: quinlan(a)transmeta.com; toasters(a)mathworks.com; support(a)netapp.com Subject: Re: multiple CIFS HOME directories?

ndmpcopy error?
by Anthony Fiarito 28 Jan '99

28 Jan '99

First off, thanks to those who replied to my previous post about moving large amounts of data between netapps. I am trying most of the recommendations and have come to ndmpcopy. I have everything set up to copy data from one netapp to a second one, but I am getting an error. Has anyone come across the following error and know of any way to remedy it? adminhost# ./ndmpcopy na1:/vol/mail/testdata na2:/vol/mail -l 0 \ -v -sa root:rootpw -da root:rootpw Connecting to na1.

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.

We are purchasing a F760 and are faced with the usual backup dilemma. To backup our F630 we have a single drive DLT robot (Breece Hill Q2.15) and use local dumps. This takes 15+ hours a day (3 tapes) and obviously doesn't scale well. So we are investigating larger robots with multiple tape drives. Currently the StorageTek 9730 is looking interesting. The problem we have is by using local dumps we need the tape robot to autoload the drives. Moreover with a multi drive robot the autoload function needs to be able to control which slots are loaded into which drives. Anyone know of the StorageTek supports this? Any other recommendations multi drive 28+ slot tape robots are also welcome. FYI. The reason we aren't just stacking two Breece Hill Q2.15's is that we have been underwhelmed with the usability and quality of these boxes. We find the documentation and user interface to be quite poor. (And they never delivered the S/W upgrade they promised) The reason we aren't using an NDMP backup S/W package is that the nature of the data on this box requires a "level 0" backup every night. Most of the features of the NDMP S/W would never be needed (indexing, etc.) and therefore be an unnecessary expense. Graydon Dodson (606) 232-6483 grdodson(a)lexmark.com Lexmark International Inc.

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.
