RE: User Quotas in CIFS Environment
by Plawner, Marom 02 Dec '99

02 Dec '99

I realize that the responses I received on this thread weren't posted to the group, so I'll give a quick overview of the e-mail's I received: Problem that users from the NT domain must be migrated into the /etc/passwd file (using the dos based on beta GUI based tool) to be able to give a users@tree quota. Responses: This is not unique to my system. It is in fact built this way. I've been told that this should be changed in an upcoming release (less than 12 months, hopefully). Quote, "The quota system within WAFL needs to be wired to the NTFS metadata that is maintained in the NTFS and MIXED file system styles. Currently it is only wired to the UNIX notion of ownership, which is why the UNIX<->NT user mappings are currently necessary to make user and group quotas work for Windows users." My Reaction: 12 months!!!! Problem: An NT based NIS server and make the NetApp a client. Anyone know of one? Responses: Good idea, nope, we don't. Problem: The DOS based migration tool crashes, can someone at NetApp fix it? Response: Nope. We don't even have the source, and we don't support it. My Reaction: This is a BAD answer. The NetApp filer provides a broken functionality (see first problem above), and the only interim solution isn't supported. Problem: Maybe the GUI version of the migration tool has hidden command line switches which can make it scriptable? Response: Nope. Why don't you just write your own script automatically update your /etc/passwd file? My Reaction: I bought the NetApp Filer since it's supposed to be a "black box" (ok, blue). The concept of the filer is that it is a simple, closed system that you just plug in a go with. If I wanted a system which I have to start building tools for, I'd download Linux for free and do it myself. (Or run Novell, or suffer with speed of NT.) Speed wasn't the issue, NetApp people... simplicity was. I don't need "just go and program it yourself" answers. I bought this for a CIFS environment, not NFS. I don't come from the "just build it in Perl" side of the tracks. Since you offer more functionality, you just understand your customer based and how the NT System Admins are different than the Unix System Admins. Problem: Maybe the wafl.nt_user.default option is connected? Response: No, read the man page. My Reaction: Right, good idea. Thanks to all of your responses. For those of you wanting to go into CIFS or using CIFS and wanting to go into quotas, I was given a suggestion to just limit the size of the /users folder. In theory it isn't a bad idea, but I'll tell you from the point of view of a company with about 4,000 people using the filer as a home directory, people will use it all up and fast! Not putting a quota won't work. - Marom

RE: NOW update?

We have a project scheduled for completion at the end of December to allow customers with text based browsers to download software from the Web. This is in direct response to issue discussed 6 weeks ago regarding customers who have filers in remote locations or colo cages where no graphics console is available. Details will come out mid-December about this new location and how to use it. -----Original Message----- From: Pete Ehlke [mailto:pde@listserv.music.sony.com] Sent: Wednesday, December 01, 1999 12:14 PM To: toasters(a)mathworks.com Subject: NOW update?

Backup Help
by Alan R. White 01 Dec '99

01 Dec '99

With the recent slew of mails about backups this question is timely. Problem 1 - we're an ADSM shop. We have all the infrastructure set up to run ADSM but until now we've not had filers. Pretty soon, all things being equal, we're going to start a project which might end up as 5TB of filers over 10 heads, in 5 clusters. At the remote site we're thinking of 5 heads with 1TB each as a snapmirror destination. There's plentiful network bandwidth available between the sites. OK, snapshots will take the bulk of our restore work but there will be the usual 'keep monthly backup for 12 months, yearly for ever (= 7 years in my book)'. Then there's what to do if one breaks (double disk hit / reconstruct failure etc etc - not likely but I'm not betting the bank on it). Checking with the ADSM folks they think they will have a pretty wholesome NetApp integration by end *next* year. Timely as usual (not). So what to do? When and if ADSM native support becomes a reality we should use it if possible so its an interim thing we need. How about backups over CIFS (because I will need the security info - NFS doesn't back it up apparently)? I didn't think local tape drives was an option due to the size of each filer (500GB) and then the number of filers (10). I reckon I'd need 4 drives on each filer and then bodies running round changing them. BTW the business requirement will be to get them a service back soonest in case of outage - snapmirror looks like a last resort because it seems a tad awkward to fail back when the primary is repaired. I've read the NetApp white papers but there doesn't seem to be an ideal solution. All help gratefully received. Regards Alan

FC-AL: Onboard vs. PCI Adapter Card
by Norman, Paul 01 Dec '99

01 Dec '99

Over the last couple days, there has been some discussion about on-board FC-AL in our filers. This summer, NetApp started shipping filers with an FC-AL adapter card rather than the on-board FC-AL to improve reliability and performance. We did this because we found errors which, though recoverable, potentially effect performance and loop stability. The problem effected a very small fraction, just a few percent, of the installed base. As for the installed base, we've been monitoring Autosupport logs each week to identify Filers that are having these types of errors and arranging for installation of an FC-AL adapter card in cases that warrant it. Our customer support organization is fully aware of this issue and if a customer calls with an FC-AL problem we review their logs for the soft-errors, and arrange for installation of an adapter card where appropriate. Since it effects a very small number of installed systems, it doesn't make sense to upgrade the entire installed base. Leave stable systems lie or if it ain't broke, don't fix it. Most filers will never see this problem and the recoverable errors indicative of the problem are easily identified --- so we are approaching this problem on a case-by-case basis. For more information, or if you have concerns about your system, contact Network Appliance customer support. There will also be more technical information posted on the NOW site before the end of the day tomorrow.

RE: Backup solutions
by Jim Cozens 01 Dec '99

01 Dec '99

We've been using Workstation Solutions Quick Restore to backup an F740(DOT5.2.3) via NDMP to an Exabyte 220 Mammoth library for a couple of months now. I've found it to be an excellent combination. One of the nice things about WS is that if you do find a bug they'll fix it quick. I haven't had any problems with the filer crashing while backing up.

According to the release notes QR does support 3-way NDMP backup and recovery. -----Original Message----- From: Brian Tao [mailto:taob@risc.org] Sent: Wednesday, December 01, 1999 3:18 PM To: Jim Cozens Cc: 'mgx(a)spruce.lsd.ornl.gov'; lpaton(a)cfa.harvard.edu; toasters(a)mathworks.com Subject: RE: Backup solutions On Wed, 1 Dec 1999, Jim Cozens wrote: > > We've been using Workstation Solutions Quick Restore to backup an > F740(DOT5.2.3) via NDMP to an Exabyte 220 Mammoth library for a > couple of months now. Does QR support 3-way NDMP dumps where the tape library is located on a Solaris host (i.e., does QR come with an ndmpd for Solaris)? Veritas also does 3-way, but only to a tape drive attached to another filer. I need something that can efficiently handle over a dozen filers dumping to a couple of Solaris boxes sharing a single stacker (like an X200 Mammoth2 library or something). -- Brian Tao (BT300, taob(a)risc.org) "Though this be madness, yet there is method in't"

RE: FTP uploads from the UK
by Sam Schorr 01 Dec '99

01 Dec '99

Don't feel alone...the US ftp site does not handle large core dumps very well either. I am constantly getting "connection closed by remote" while trying to send a core of approx. 730 meg (F760 with gig of memory). I've been "hearing" about an upgrade for months. Maybe their ftp process has "feature creep" so they can't do what has been going on for years by others quite successfully. -----Original Message----- From: Dave Atkin [mailto:dla1@york.ac.uk] Sent: Wednesday, December 01, 1999 1:00 AM To: toasters(a)mathworks.com Subject: FTP uploads from the UK I'm having awful trouble uploading core dumps these days from the UK. Very often it goes slowly and then the ftp times out with a "broken pipe". Access to everwhere else (including the Netapp web site) is quite fast so I don't think our UK academic network is to blame. At the moment the mean time between crashes on one of our 740s is less than the mean time to get an upload to work!! Is there any chance that Netapp could look at this or alternatively perhaps provide a European ftp site? Or maybe a web-based upload facility might be provided as an alternative to ftp (dunno if that would be more reliable or not..).

SnapMirror
by Gilles TOURPE 01 Dec '99

01 Dec '99

Hello, Get a question regarding SnapMirror ... Did someone is using it to replicate 2 filers ( na1, na2 ) to 1 guy on a remote site ( nahots ). The idea is to backup all datas ( no REAL TIME ) using the snapMirror software. Do you know if it integrates reporting functions ? Volumes transfered over Time it took, Errors, What are the way to get those reports ( MAIL, update HTML pages on the FilerView ... ). Well, basically, what I like to get is a nice successful story :-) Thanx Gilles ------------------------------------------------------------ Gilles TOURPE - System and Network Administrator APS BNP ARBITRAGE - Salle des marches ACTIONS - PARIS - France Phone : (33)-1-40-14-24-03 e-mail : gilles(a)bnpcn.com
