RE: Data Copy from Filer to Filer
by Knight, Graham 07 Apr '01

07 Apr '01

Ndmpcopy version 2 doesn't require command line passwords. It prompts for the passwords when the session starts. The source is available on the ndmp.org website. I haven't played with it, but it looks interesting. For version 1 you can hardcode the password and compiled it down to a binary that only root can read or execute. That stops people from being able to find the password from the executable unless they are the root user. It worked pretty well when I did this at my previous job. All you have to do is add default passwords in the main.h file. Hardcode the filer passwords in the DEF_SRC_AUTH_PASSWORD and DEF_DEST_AUTH_PASSWORD definitions and recompile. It really helps if all you filers have the same password. :-) Graham -----Original Message----- From: Brian Tao [mailto:taob@risc.org] Sent: Saturday, April 07, 2001 8:00 AM To: Francett, Robert D (SAIC) Cc: 'Jessica Fernandez'; toasters(a)mathworks.com Subject: RE: Data Copy from Filer to Filer On Fri, 6 Apr 2001, Francett, Robert D (SAIC) wrote: > > The form I use is: > $ ndmpcopy filer1:/vol/volname/qtree filer2:/vol/volname/qtree -sa root:password -da root:password -dhost GbE_IP_address -level 0-9 This is the greatest failing of ndmpcopy... plaintext passwords to privileged accounts on the command line, in your shell history, up there in a "ps" for everyone to see, etc. It would be nice to have an "ndmp" user on the filer that can *only* initiate or receive NDMP sessions. Combine that with a new ability to read user/password information from a file in ndmpcopy, and you at least have some modicum of security. One of these days, I'll hack ndmpcopy to do that... unless someone else has done that already. ;-) -- Brian Tao (BT300, taob(a)risc.org) "Though this be madness, yet there is method in't"

RE: Filer Serial Connectivity

Please forgive the ignorance of a sales guy lurking an engineers' discussion list... Why would you want this type of solution instead of/in addition to FilerView? Granted, FilerView is network-bound (correct?), but if you need to dial in under a complete network outage wouldn't any RAS/terminal server solution do? (I'd be concerned about security issues with my filer console ports connected indirectly to a modem, though.) For those familiar with other remote management solutions, how does NetApp's remote manageability compare with, say, Compaq's Remote Insight Board Lights Out Edition? TIA.

Jessica, ndmpcopy, at the command line of a UNIX admin host works very well, particularly if you have a GbE (Gigabit Ethernet) connection for filer to filer data migration at any level - volume or qtree, even data from one location to another on the same filer. The form I use is: $ ndmpcopy filer1:/vol/volname/qtree filer2:/vol/volname/qtree -sa root:password -da root:password -dhost GbE_IP_address -level 0-9 ndmpcopy is downloadable, compiler for Sun, from the site: http://www.ndmp.org/ <http://www.ndmp.org/> If you have a license, SnapMirror works really well too, but at the volume level. More to setup but less impact if outage is required.

I have estimated time of 28 hours to transfer 70 GB via a copy command on the host machine. I have tried to copy via CIFS accessing from NT servers using drag and drop.

RE: BudTool transition news

To Marion and any other Budtool users on this list. NetApp received this offical notification from Legato just this week, on the new migration policy. As we understand it Marion, it is available now. -----Original Message----- From: Marion Hakanson [mailto:hakanson@cse.ogi.edu] Sent: Friday, April 06, 2001 6:30 PM To: toasters(a)mathworks.com Subject: BudTool transition news Folks, Dunno if it's top secret, or what, but this week I innocently (hah!) asked Legato about transferring my BudTool license to a new NetApp that may be coming in soon. Their website says host transfers are free, so what the heck? Anyway, instead of getting an answer, I got directed to my local Legato salesperson, who informed me that they've finally come to their senses and are offering a one-for-one exchange to replace our BudTool products with equivalent NetWorker products, at no cost other than putting it all back on tech-support contract. I checked, and it's not 1-April-2001. Maybe by the Mayan calendar? By my investigation so far, NetWorker-6.1 claims it will do everything our BudTool-4.6.1 does, with the exception of: (1) NDMP backup to non-NetApp tape drive. An extra-cost SnapImage option turns your Networker tape host into an NDMP tape server to provide this functionality. OK, so it's not quite 1-for-1. (2) Cloning NDMP tapes. They say that'll be along soon (I forgot to ask if I could do that with SnapImage). But one can do a second backup to offsite media to partially work around this limitation. I'm still not wild about Networker, but "Free is a very good price." Well, not counting the initial $30k investment in BudTool, anyway. So, has anyone else heard about this? I could find no mention of it (nor any previous transition programs) on their website. Regards, -- Marion Hakanson <hakanson(a)cse.ogi.edu> CSE Computing Facilities

Hi Jeff, I'm curious, what are the issues that stop you from using ndmpcopy?

Hi Jessica, ndmpcopy is a great way to go. There are compiled versions on the NOW site, and the source code is on the ndmp.org site. ndmpcopy starts a dump on one filer and pipes it directly to a restore on another filer (or the same filer). It can be done on a directory level. It will preserve all of your unix permissions and NT ACL's when making the copy. It is also a much faster way to transfer data because there is no intermediate machine involved in the transfer. Yes, volcopy will only copy entire volumes.

RE: Windows, free space displays, gah
by Tom "Mad Dog" Yergeau 06 Apr '01

NetApp has an unsupported perl script that you can run as a cron job that will scan for users near their quotas and alert them to the fact. You can download the script from the NOW site. http://now.netapp.com/NOW/download/tools/disk_usage/ Another option is to upgrade to ONTAP 6.1, which supports quotas for Windows users based on SIDs. Also, I'm told that when you use the Windows quota feature, the amount of free space available to the user appears to be the amount of their quota that is free. Sounds like just what you need. :-) Tom -----Original Message----- From: Mike Knell [mailto:mike.knell@cs.tcd.ie] Sent: Friday, April 06, 2001 7:24 AM To: toasters(a)mathworks.com Subject: Windows, free space displays, gah Mornin' all, I'm besieged by Windows users complaining about not being able to find out what the state of this mysterious "quota" thing is, and complaining about files going missing because they've gone over quota, and _naturally_ this is all the fault of our filer rather than of either the users themselves for not keeping an eye on how much disk they're using, or Windows applications for not handling write failures gracefully. What they tend to do is point to the Windows (NT and 2000, btw) disk free display and say "Look! It says I've got 35GB of free space!" without working out that this is the free space on the entire volume rather than in their quota. What are peoples' views on providing state-of-quota information to Windows users? Ideally, the disk free display should show the state of their quota rather than the volume, but things just don't seem to work that way. We have a web page they can query their quotas from, but either that or the simple act of logging into a Sun and saying "quota -v" is considered to be rather complex and not pro-active enough..
