t> Or you can use different group names with the same gid and everything will t> work fine. This is what we do. ;) We use NIS for everything. The degeneracy state of group.bygid map should be causing you subtle problems somewhere. The 1k limit is inherent in the NDBM code that NIS relies on. You can change this limit and recompile if you have access to the source for libc/ypbind/ypserv/ndbm on ALL platforms you support but that is a major pain in the ass. Is netapp planning to support LDAP based access to passwd, group, etc... at some point[1]? Solaris and Linux have been able to do this for a while and RedHat 6.1 even comes with the packages. It doesn't suffer that limit and purports to perform better[2]. Rob 1. I realize that this would be an un-official word on the toasters list. 2. I have not tested this myself yet. The traditional NIS server is single threaded and really slow. LDAP parsing and record searching is a more expensive process than a simple NDBM lookup but the server should perform better against multiple clients.

now.netapp.com now needs javascript/cookies?
by Luke Mewburn 18 Oct '99

18 Oct '99

Since when has now.netapp.com needed JavaScript & Cookies? I find this unacceptable: a) I have JavaScript (& Java) disabled on my GUI browser because it increases the reliability and security. b) My text browser (lynx) doesn't support JavaScript. With NetApp's drive to encouraging customers to using now.netapp.com as a method to lodge support calls, I remind them that until this point I could do everything (manage my filers, submit calls, look at bug reports/new releases) via a text based connected *if* I needed to. Next thing we know the initial release of new features will only be available via Windows and/or Web based GUI interfaces. Memo to NetApp: if you do this, you will lose customers. Luke. (Afraid of the slippery slope to brain damaged interfaces because of PC magazine perceptions that filers ``need'' a GUI..)

Been there, done that; it won't work for everything, and you will eventually run into NIS trouble (see other message). The best thing to do is live with the 16 group limit until a new standard version of NFS supports access lists, or wait for LDAP to become more widely adopted. I think it *is* on Netapp's agenda, but most vendors are slow to adopt it. Bruce

> CLI will be out in the next few years, no matters where your nostalgia goes. As I've said before (about Wellfleet/Bay/Nortel routers): Having a GUI is fine. Having a GUI *only* is terrible. Some of us swear by command line interfaces. They enable you to use any kind of terminal, and to work from home or over a slow dialup line. Yes, clearly, the use of GUIs is increasing. However, for us, a product which offers management via a GUI only starts off with a significant disadvantage (or disincentive for purchase, if you wish).

group issues
by mcbride2＠us.ibm.com 16 Oct '99

16 Oct '99

I am having an issue regarding the number of groups and, the numbers of users per group at our site. We have 3 toasters running 5.2.1P2 being administered by a solaris 2.5.1 server. We have about 75 unix style qtrees for both NFS and CIFS protocols. I have a requirement that several users need to be in more than 16 groups. I believe modifying the Solaris kernel will not only slow down the access, but may present problems on the filer. Also, I require to have more than 1024 characters needed per group entry. I have tried creating sub-groups and a master group within the group file(see below) - I cannot get this to work. Maybe I need to upgrade my Solaris NIS server? example: project1:*:100:usera,userb... project2:*:101:usery,userz mstproject:*:102:project1,project2 I would think someone has encountered this problem before. I would appreciate any feedback regarding these issues. Mike McBride IBM Global Services Unix and NT Server Support mcbride2(a)us.ibm.com (760) 634-6239

RE: Model 1400 and Y2K
by Norman, Paul 16 Oct '99

16 Oct '99

Graham, Jeff is incorrect. The information on the NOW web site is correct. FAServers, including the 1400, can not run 5.x code line of Data ONTAP. The NetApp Y2K statement is available on the web: http://www.netapp.com/y2k.html It includes a section on FAServers: FAServer® models 400, 450, 1300, and 1400 have not been tested for Y2K compliance. All of these models ceased production in October 1995 and support in April 1998. If you have one of these models, contact your Network Appliance Sales Representative or the Installed Base Group to purchase an upgrade to current filer products. The Y2K statement on the web also includes my name as the corporate contact for Y2K queries. So please feel free to e-mail/call me if you need further clarification.

mailboxes on toaster
by George Kahler 15 Oct '99

15 Oct '99

Hey folks, I'm looking for information that would help us alleviate a bottleneck with mailboxes and home directories on toaster(s). Yah, we still run sendmail and our inboxes are in the old Unix style format (one file per user, multiple messages per file). I heard some of you mention Maildir and I also came across information on mbx format. It doesn't look like I would have to do much to switch over to mbx vs. Maildir. Q: Will mbx buy me performance on the toaster ? Q: Is Maildir a better choice ? Please include any other suggestions. Thanks, George ------------------------------------------------------------------------------- George Kahler e-mail: george(a)yorku.ca Systems Administrator humans: (416) 736-5257 x.22699 Computing Services, York University machines: (416) 736-5830 Ontario, Canada, M3J-1P3

SUMMARY:Impact of adding disk to filer
by Frank Smith 15 Oct '99

15 Oct '99

Just in case anyone was curious, the consensus was that it should have little or no impact to add a disk to a volume, and that is the way it actually turned out. Physically adding the drive to the shelf froze it for 10-15 seconds, prompting my initial concern and question. The 'vol add vol0 1' command took upwards of 5 minutes to zero the disk, but the actual increase in volume size was instantaneous after the zeroing completed. There was no noticeable increase in CPU or NFS ops during the zeroing or addition (although our traffic is rather bursty in nature, but I did not see any sudden big numbers in CPU or ops). -- Frank Smith fsmith(a)hoovers.com Systems Administrator Voice: 512-374-4673 Hoover's Online Fax: 512-374-4501

Model 1400 and Y2K
by Graham C. Knight 15 Oct '99

Does anyone know if a model 1400 can be made Y2K compliant? The NOW website does not include this model in it's list of systems that can run 5.x Thx, Graham

Impact of adding disk to filer
by Frank Smith 15 Oct '99

15 Oct '99

What will happen if I add a disk to a volume (NetApp C720)? I learned the hard way that adding the drive to the shelf interrupted all NFS ops for 15 seconds, the docs said it would take that long to add it as a hot spare, but didn't mention that the filer would completely freeze while it did it. If I add a disk to a volume, what will it do to performance, and for how long? I don't mean long-range gains from having the data spread over more spindles, I mean what immediate impact will it have on current NFS clients. Will it just be a temporary increase in CPU as it spreads the data or will it freeze for some period of time, and if so for how long? Current sustained load on the filer is several hundred NFS ops/sec, and any pauses cause significant problems on the client systems, so I want to have a better understanding of what will happen when I give the vol add command before I actually do it.
