RE: wafliron output -- is wafl OK?

Hi toasters... currently i am running a wafliron. My question now is, do i get any kind of output after wafliron has finished?? Do i see if there where any wrong blocks and if Ontap was able to solve the problem or not?? Or is there any extra command to assure that there is no problem in wafl left?? Regards and thanks for your help Jochen

If you do this, I assume you had to set some thresholds somewhere on the filer right? I didn't realize that sending those thresholds would do anything other than send snmp traps. I'll consult the docs, but do you have a quick syntax on how you set those thresholds (preferable from the command line). ----- Original Message ---- From: Glenn Marsh <glennm(a)latticesemi.com> To: toasters(a)mathworks.com Sent: Monday, January 15, 2007 1:27:08 PM Subject: Re: User defined Notifications I have been using SWatch (System Watch) for some time now for this purpose with great success. http://sourceforge.net/projects/swatch/ It is Perl based and fairly easy to configure. ************************************************************************ Glenn Marsh Lattice Semiconductor Corporation Senior Unix Systems Administrator 5555 NE Moore Court CAD Engineering Hillsboro, Oregon 97124 glenn.marsh(a)latticesemi.com 503-268-8000 503-268-8136 phone - 503-268-8459 fax ************************************************************************ ____________________________________________________________________________________ Looking for earth-friendly autos?

NetApp equivalent of all_squash,anonuid=100,anongid=100
by NetApp 15 Jan '07

15 Jan '07

I'm trying to set up an NFS path where all clients get squashed to a single UID The normal export doesn't work, as my NFS clients are Linux 2.6 with real uid/gids sent /vol/vol1 -sec=sys,rw,anon=100 In this case, only ROOT client access get squashed to uid 100. Instead, here's what I tried: /vol/vol1 -sec=none,rw,anon=100 Unfortunately, my Redhat Linux client (2.6.9-42.ELsmp) refuses to mount Mounting NFS filesystems: mount: 192.168.1.10:/vol/vol1 failed, security flavor not supported Packet traces show the Linux system sends the MNT request with Flavor AUTH_UNIX, and the NetApp replies OK-Flavor:AUTH_NULL along with the appropriate supplemental fsid file handles. Only, Linux is 'smart' and refuses. I also don't have any server side control over GID either.

We just run an rsh "quota report" every 15 minutes an have a perl script send the emails. This solution becomes more portable if you decide to switch NFS appliances at some later point (but why would you!). We turn on wildcard quotas and get per user usage info too. It would be really nice if you could just set thresholds for alerts from the command line itself and define alerts to be emailed. ----- Original Message ---- From: "Warkentin, Grant" <Grant.Warkentin(a)calgary.ca> To: Christian Mikovits <christian.mikovits(a)cubit.at>; toasters(a)mathworks.com Sent: Monday, January 15, 2007 11:35:21 AM Subject: RE: User defined Notifications DFM Works like a charm for us.

If, in the middle of the week, I restart the filer's disk quota system, then DFM will send these e-mails. Even if a full week has not elapsed. I have to be careful when adjusting quotas to avoid sending out too many alerts. This mostly happens when we adjust tree quotas. For user quotas, I have several default qtrees. To increase a user quota have been moving that H: folders to different qtrees to increase the quota. It's a bit kludgy but it appears to work okay for us (8,500 H: drives).

Check and see if you have a "cifs top" command in ONTAP. I'm not sure what release introduced it, but it's on my 7.2 simulator, but I think it's older than that.

RE: Preventative/proactive filer maintenance

I'd recommend the scheduled WAFL reallocates to help defrag. I'm curious about the fact they question the last time it was wafl_ironed - this looks for and fixes corruption, not poor layout. I'd start by monitoring performance - stats output\sysstat and statit. Perfstat (from the now site) is a good tool to collect a lot of data, but unless you've been working on filers for a number of years, it will be mostly gibberish (though some output is similar to what you'd find on unix systems).

RE: add bigger disk into raidgroup with smaller disks

Agreed. -----Original Message----- From: Fox, Adam [mailto:Adam.Fox@netapp.com] Sent: Wednesday, January 10, 2007 5:31 PM To: Glenn Walker; Willeke, Jochen; tmac Cc: toasters(a)mathworks.com Subject: RE: add bigger disk into raidgroup with smaller disks Yes, I can confirm that. But that doesn't *replace* any of the 50GB disks, which is what I understood as the original question. The rules are different if you add a disk vs. fail out a disk. If you were to fail out one of the 50GB disks in your scenario, and only a 100GB disk was available, WAFL would only use 50GB of the 100GB disk and even if you failed out both 50GB disks, the two 100GB disks that replaced them would still be 50GB.

Looking for Beta Testers
by Harry McIntosh 10 Jan '07

10 Jan '07

Hi Toasters: We have a new software product for use with filers, and we are looking for beta testers for it. We can offer a free license for the product to a limited number of beta testers. The product is named Folderscape, and is a combination of Windows Explorer and FilerView. For details, please visit our website at Folderscape.com. Although future versions of Folderscape will include Unix functionality, the current version works only with NTFS volumes. If you have NTFS volumes, and would like to beta test the software, please let me know. Thanks, Harry McIntosh PAC Software, Inc. -- View this message in context: http://www.nabble.com/Looking-for-Beta-Testers-tf2955517.html#a8267591 Sent from the Network Appliance - Toasters mailing list archive at Nabble.com.

I can't seem to shake the memory of one other rule - if you add a 3rd disk of larger size, the extra space DOES get used. At least it used to be like that in the past, and I assume WAFL hasn't changed.

So berkcom.net redirects to zerowait - a 3rd party netapp reseller (used stuff?)... and the guy that emailed me\the list in response to the query just _happens_ to know a vendor? Convenient!

They know their products and are responsive, both on purchasing and parts/support. For systems, their quotes were significantly lower than NetApp's and their advice was right-on -- no sleazy overselling. Hooked us up with a spare head on-site for less than a kit o' parts, which will make swapping out a lot faster in the event of a serious failure. Nice folks to work with.
