Well, my GUESS is that the error, essentially, is saying that your entry for the group "uk" is too long. Normally I'd say check the group file on the filer but you mention NIS in the subject line, so I'd say check the group file on the NIS master. The filer *should* be able to accept group lines as big as your UNIX server. Either your group line is actually too big on your UNIX server (in which case it probably was broken and you just didn't know it), or the filer's buffer needs to be increased. In the latter case, you'll have to wait for a patch or new release that has a bigger buffer. Bruce

SNMP support on filers
by agy 03 Jul '98

03 Jul '98

Hello All, NetApp is planning to enhance the SNMP support in the filer in an upcoming release of the OS. Due to some risk factors, I'd rather not promise that it will be the next major release (next year), but that is the current plan. Things we definitely plan to do when this support is added: (a) GETs for general CIFS-related filer parameters. (b) GETs for statistics on all SMB requests, both cumulative and per client. (c) Generic TRAP support, with settings and parameters for each available trap manageable through Filerview. I would welcome feedback on: (a) Additional GETs you think are necessary. (b) Trap support considerations. (b) Specific traps you think should be implemented. (d) Other things pertaining to SNMP that would be helpful. It would help us if you could indicate the relative importance-- to your company's future infrastructure plans--of things that you suggest.

bug fix for na_snapmon
by Daniel Quinlan 02 Jul '98

02 Jul '98

Hi everyone. I just fixed a minor bug in na_snapmon (it would try to delete dump snapshots all of the time instead of just the ones that were more than two days old). The copy that I put up on my NetApp web page doesn't have that problem: http://www.pathname.com/~quinlan/netapp/ That could actually cause some problems for older releases (before 4.3x) affected by bug #650 that would crash the filer if you tried deleting a snapshot that's in use. Now, na_snapmon makes the assumption that dumps older than two days are safe to delete, or at least you're running 4.3 or later. Dan

Re: SNMP support on filers

Hi Alan. There are a few things: - Information located in the "Tree" field of the "quota report" is missing from the SNMP quota information. (this is bug 8704, and log 35271) - Putting CIFS and HTTP statistics into SNMP, starting with the same information that's in "sysstat", but also the other information you can get from the "cifs" command. - getting snapshot information via SNMP - per-client NFSop/CIFSop/HTTPop statistics Thanks. Dan

My main advice would be to make sure anything obtainable through SNMP is also obtainable from the command line and from the remote GUI; i.e. if you're going to have per-client stats for CIFS in SNMP then it should be available via a "cifs stats" command or similar as well.

na_snapmon: snapshot monitor
by Daniel Quinlan 01 Jul '98

01 Jul '98

I finally got fed up with deleting snapshots by hand when they started using too much disk space, so I created a simple snapshot monitor that automatically deletes snapshots when they start using more than 100% of the space reserved for snapshot usage. Now, I configure each filer to schedule more snapshots than I really want and I use only "snap reserve" to limit how much disk usage is taken by the snapshots. If a filer's data turnover rises, it automatically scales the number of snapshots back. For example: Jun 26 10:30:36 sodium na_snapmon: rsh uranium snap delete hourly.3 Jun 26 10:33:03 sodium na_snapmon: rsh neptunium snap delete nightly.1 Jun 26 10:34:49 sodium na_snapmon: rsh thorium snap delete hourly.2 Jun 26 10:40:04 sodium na_snapmon: rsh neptunium snap delete hourly.3 It will also try to delete dump snapshots that are older than two days old, and it will also ignore snapshots that have been specially created or renamed. The best way to run this is as root cron job, every ten minutes or so. This runs on Linux now, but should also work on Solaris. Other Unix systems with very minimal modification. ------- start of cut text -------------- #!/usr/bin/perl # na_snapmon - monitor snapshot usage and keep it under control # Copyright (C) 1998 Daniel Quinlan # # This program is free software; you can redistribute it and/or modify # it under the terms of the GNU General Public License as published by # the Free Software Foundation; either version 2 of the License, or # (at your option) any later version. # # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Quotas
by Raymond Brennan 01 Jul '98

01 Jul '98

I'm sort of new to all this, so here goes : I want to create a root directory called, say, dog. I then want to create a subdirectory called pup. I want to limit the size to which pup can grow to, say, 50 Mb. The thing is, the quota qtree command won't accept slashes in the qtree name. Also, if I create "dog" by doing # mkdir dog then do #cd dog # mkdir pup then go to the quotas file on /etc and do /dog/pup 10G 10K and run quota on I get "/dog/pup is not a quota tree. In short, how do I set quotas on file systems a number of steps down the tree ? Why can't I do /dog/pup 5G /dog/puppy 5G

OT 5.?
by Weeks, Thomas 01 Jul '98

Just curious... how is the OT 5.x software working for eveyone? Any problems? Stability probs? Backout (to 4.3.4) problems? What about quotas and the like? Just curious...

Re: what data is being used?

I recall asking for this in an RFE sense a year ago as it would be incredibly useful. Sun just put the capability to track the load on disks at the partition level in Solaris 2.6 - this sort of stat on a filer would be just as useful IMHO Per quota tree seemed most natural to me as that is already a distinctive structure in filer housekeeping meta-data. Directory level gathering might be too much load to put on a filer which is meant to perform under high demand... ...how about an admin command that flips a bit on a directory and makes it a watchpoint in the filesystem - accesses against anything beneath it count on that directory's stats. Even if the total number of such points were limited to put a boundary on overhead in the filer, it would still be a useful analytical tool.
