RE: moving files between filers
by Flaherty, Michael 24 Jul '02

volcopy does work well, the destination volume blocks are copied identically to the source volume. One benefit of using ndmpcopy is that the data is written contiguously which will eliminate any fragmentation.

Hi all, Is anybody using a toater for clearcase 4.2. Why I am putting it here is because I need to the real life scenarios of it implementation. If anybody could help me that'll be really great.

ONTAP 6.2.1 vs 6.2R2D6 vs ???
by Chris Thompson 22 Jul '02

22 Jul '02

I am wondering which release of ONTAP I should be running on a leading-edge (but production) server here... We are currently running 6.2R2D2 --- the D2 part because we wanted the fix for 70674. We usually run the FCS release, but not a Dx one, so this makes me somewhat uneasy. Now 6.2.1 is out and FCS, and has 70674 in its fix list, so it would be natural to change to that. But meanwhile we've got the question of 75012 (the CA-2002-19 bug-in- -most-known-DNS-resolvers thing) outstanding. We think we're pretty well protected against it being exploited, but will be a lot happier with a fix. This *isn't* listed as fixed in 6.2.1. The Bugs Online entry for 75012 names a number of Dx releases in which it is fixed, including 6.2R2D6, but there's no mention of a 6.2.1D<anything>. So I need to decide between 6.2.1, 6.2R2D6, or waiting for something else. Maybe toasters isn't the best place to ask about this ... can NetApp people even post to the list again yet?

Ownership of "/etc"
by David Lee 22 Jul '02

22 Jul '02

On both our new filers, running 6.1.2R1, I have just noticed that the ownership of its "/vol/vol0/etc" belongs, not to the expected "root", but to an apparently arbitrary uid "20041" (gid "30"). Fortunately: (a) we have not allocated that uid to anyone; (b) I think the only machine to which "/etc" would be user-accessible (a Solaris UNIX box fro our user admin.) can have access restrictions to prevent telnet/ssh-like user-access. Nevertheless, it does seem a little worrying (correction, potentially very worrying) that this critical "/etc" directory is owned by an ordinary user. (Just suppose this October's student intake allocates that uid to someone who likes exploring...) All the contents of "/etc" are root-owned, except for a subdirectory called "java" and within that some (not all) of its contents: drwxr-xr-x 3 20041 30 4096 Jun 11 08:11 . drwxr-xr-x 20 20041 30 65536 Jul 22 14:53 .. -rwxr-xr-x 1 root other 1912820 Jan 9 2002 .jitcache.db -rw-r--r-- 1 root root 1912820 May 14 14:05 .jitcache.db.saved -rwxr-xr-x 2 root other 8844945 Jan 8 2002 classes.zip -rwxr-xr-x 2 root other 8844945 Jan 8 2002 classes.zip-inuse -rw-r--r-- 1 20041 30 238737 Oct 13 2000 crysec.zip -rw-rw-r-- 1 root root 139895 Jun 14 00:35 jit.log -rw-r--r-- 1 20041 30 505097 Oct 13 2000 jsafe.zip drwxr-xr-x 3 root root 4096 May 14 14:05 lib -rwxr-xr-x 2 root other 1422554 Jan 8 2002 netapp.zip -rwxr-xr-x 2 root other 1422554 Jan 8 2002 netapp.zip-inuse -rw-r--r-- 1 20041 30 217093 Oct 13 2000 phaos.zip -rwxr-xr-x 2 root other 1942824 Jan 8 2002 redshift.zip -rwxr-xr-x 2 root other 1942824 Jan 8 2002 redshift.zip-inuse -rw-r--r-- 1 20041 30 113216 Oct 13 2000 secureadmin.zip -rwxr-xr-x 2 root other 139753 Jan 8 2002 servlet.zip -rwxr-xr-x 2 root other 139753 Jan 8 2002 servlet.zip-inuse Is this general, affecting other sites, or does it suggest that something peculiar happened at our installation?

quotas over limit: determination thereof
by David Lee 20 Jul '02

20 Jul '02

If what follows is in the manual or is a FAQ, then just point me in the direction... Executive summary: Is there an easy way (variant of "quota report" perhaps?) to discover which users are over-quota? Detail: We are beginning to migrate our home directories (15K-20K of them) from Solaris to NetApp. Quotas are a vital part of the control of these directories. Under Solaris (trad. UNIX), each user has an explicit quota. While this is possible under NetApp, it seems far more sensible to use default quotas where possible (and the documentation encourages this). We have set up some reasonable default quotas, and are using rsync (thanks, folk!) to get the user files prepared in the future NetApp location: transferred (from 20+ volumes across three Solaris fileservers) and kept in sync. Naturally a few of our users have more data than our NetApp default quotas. What we simply want to do is identify these exceptions so we can apply explicit quotas. We will, if possible, adjust the defaults so that the number of exceptions, from our 20K user-base, is reasonably small. Under Solaris etc., the output from its "repquota" command was easily eyeball-able (I know, no such word!) for such exceptions: "+" and expiry times. Is there a variant of NetApp's "quota report" that either restricts output to over-quota users, or has a field indicating over-quota, or similar? Or is the NetApp convention simply to cobble together a bit of awk/perl to extract those lines (from the total 20K) in which "Used" exceeds "Limit"? Thanks in advance. -- : David Lee I.T.

RE: arp spoof, 840 with 6.2.1

Brian, Snapmirror and vol copy turned out not to be an option, because the 760 is at 5.3.1; we're getting the 'volume is in transitional state, aborting' error even though the destination is offline. NDMP copy looks like the remaining method, the 760 is being upgraded to 6.2.1 and I want to duplicate the data before starting that. Piotr, Yes, disks and data too. %-{)# What I saw from the first attempt was no response to ping, on either side, even after doing ifconfig down/up of the e9b nic. Maybe the magic arp has leaked out the switch I was using? After connecting the original filer I had to do arp -d and ping again, before it would respond to the unix host mount request. -----Original Message----- From: Brian Long To: Toal, Dave Cc: 'toasters(a)mathworks.com' Sent: 7/19/02 10:37 AM Subject: Re: arp spoof, 840 with 6.2.1 Dave, Are you replicating the data to the F840 or just moving shelves?

RE: NT Domain Authentication and Filer Access
by Chuck Tomasi 18 Jul '02

18 Jul '02

It sounds like there is an inconsistency between the UNIX login name and the Windows domain\login name for that user. If they are the same, then odds are that the user and the filer aren't in the same domain. The joys of multi-protocol environments. Some of us learned this the hard way... There are two ways to approach this. The first is to do your best to keep the UNIX login name (e.g. ctomasi) the same as the domain login (TGI\CTomasi). Note, case doesn't matter - most of the time. If, however, the filer is in another domain (assuming full NT trusts are setup between the domains) you'll need to start tweaking the /etc/usermap.cfg file on the filer. This is a handy file. Often times it is used to map "Domain\Administrator" to "root" so you get all your admin priviledges from either world. It can also be used for other things (see the docs and/or the comments in the file.) In our case, we have lots of domains which we will hopefully be consolidating in to fewer with Win2K Active Directory, but that's beside the point. We use an entry *\* == * in the usermap.cfg file to help the filer look in other domains to authenticate the user. In my case, the filer is part of the Win2K domain "NA", but I'm "TGI\CTomasi" and my UNIX account is "ctomasi". That entry starts a search for various PDCs (see CIFS PREFDC for some other helpful info.) Note, this could take a while to authenticate a user if you have to search a bunch of domains. The user may perceive this delay when they open a connection to a CIFS share for the first time on that filer. The filer is just trying to match the Windows name (credentials) with a corresponding UNIX account. You may need to help it along if you're dealing with multiple domains or if the login name doesn't correspond between Windows and UNIX. I hope that helps. --Chuck -----Original Message----- From: Jessica Fernandez To: toasters(a)mathworks.com Sent: 7/18/2002 12:21 PM Subject: NT Domain Authentication and Filer Access I am new to administering a filer via NT. Our filers have always been administered from a UNIX host. We are migrating users from a UNIX environment to an Windows NT/2000 environment.
