Netapp 3040 Ontap 7.3.3 latency spikes - crashes vmware
by Fletcher Cocquyt 25 Aug '11

25 Aug '11

Originally attempted to post June 22, 2010! - thanks for fixing the list - We have since identified the issue by deconstructing the IOPS behind the latency spikes and resolved per: http://www.vmadmin.info/2010/07/vmware-and-netapp-deconstructing.html Hope it proves useful for anyone else with similar issues On 6/22/10 10:19 AM, "Fletcher Cocquyt" <fcocquyt(a)stanford.edu> wrote: Hi, We have a 3040 cluster hosting 11 vSphere hosts with 200 VMs on NFS datastores. We see latency spikes 3-4 times a month as reported by Operations Manager. We hoped our upgrade from 7.3.1.1 last week to 7.3.3 would help, but we¹ve had many spikes up to 1 second take out a NFS mount and all several of the VMs since going to 7.3.3 We previously determined the High & medium IO VMs and either aligned them or migrated them to local disk - has NOT helped - still getting the spikes. I have another case opened with Netapp. Following the notes in this latency spike related thread, http://communities.netapp.com/message/30657 I ran the wafl_susp -w to check the pw.over_limit Turns out ours is ZERO (is it relevant to NFS?) I suspect an internal Netapp process is responsible for these (dedup?) - we had it disabled on 7.3.1.1 - 7.3.3 was supposed to fix this (we re-enabled de-dup after the upgrade) And the latency spike outages are back Will share any info from the case thanks for any tips, -- Fletcher Cocquyt Principal Engineer Information Resources and Technology (IRT) Stanford University School of Medicine http://vmadmin.info

Command syntax
by Jeff Cleverley 24 Aug '11

24 Aug '11

Greetings, I haven't been able to post for quite a while so I'm quite happy things look good (assuming my post goes through). I thought I'd try breaking up the discussions about the domain name and test emails with a NetApp question :-) I was reading comments about reallocate with regards to a blog and someone posted this command to run: "stats show disk:*:disk_busy" I don't recall ever seeing anything about special constructs or functionality using the colon delimited fields. If this is available I'm guessing there might be other cool tricks available also. Does anyone know where there is documentation on how to use this? Thanks, Jeff -- Jeff Cleverley Unix Systems Administrator 4380 Ziegler Road Fort Collins, Colorado 80525 970-288-4611

RE: Hosting and branding of toasters list (was "Re: Google Groups?")
by Reginald Jefferson 24 Aug '11

Chris - toasters.net is a great idea that seems hard to disagree with. teaparty.net is fine with me too. Tom - THANK YOU for hosting this list for all of us. Reggie Reginald Jefferson Sr. NetApp Support Engineer Volo Labs reginald.jefferson(a)vololabs.com ________________________________ From: toasters-bounces(a)teaparty.net on behalf of Christopher B. Allison Sent: Wed 8/24/2011 8:52 AM To: toasters(a)teaparty.net Subject: Hosting and branding of toasters list (was "Re: Google Groups?") I read Brian's proposal as three separate arguments: 1) The toasters mailing list should not be hosted on a domain which many people would probably associate with a political group. ("sends a political message") 2) The toasters mailing list should not be hosted by an organization which is smaller in size than Google Inc. ("moving from one boutique mailing list hosting service to another") 3) Google Inc the best choice to host the toasters mailing list. ("moving from one boutique mailing list hosting service to another") Several people have replied to Brian's initial email with some variant of "Agreed". To those people I ask: To which parts (some? all?) of Brian's suggestion are you agreeing? I'm inclined to concur with point number one. I realize that Tom has held registration of teaparty.net since before the onset of the current political movement and that (as per the disclaimer at the top of http://teaparty.net/) he disclaims any and all affiliation with said political movement - a point which it seems may have been lost on one or two respondents - but I agree with Brian that the domain name has the potential to be misinterpreted by others who (as such) might be disinclined to consider joining the list or who might otherwise be confused as to the list's purpose or tenor. That being said, I do not agree with points two and three. I think it is lovely that toasters has moved back to its initial home on the internet (and thank you to the original founders, everyone who has provided hosting over the years, and the current host for all that you have done!), and I see no need to move the list to Google Groups or any other host. It appears that the domain name 'toasters.net' is available for registration, and I would be happy to register it on Tom's behalf, if he is so interested. Tom?

List is sluggish and takes some time to send posts out
by Tom Yates 24 Aug '11

24 Aug '11

As some have noticed, the list engine has been backlogging posts to the list today; in some cases, email hasn't been sent out until 60-120 minutes after it was received. I'm sorry about this. I think I've identified the "feature" of mailman that was causing this, and changed it. When I tested my mailman to see if it could cope with the toasters traffic, I didn't anticipate seventy posts in a single day. The backlog is being rapidly processed, and we should soon have caught up. -- Tom Yates - http://www.teaparty.net

TOASTERS LIST IS MOVING: PLEASE READ
by Todd C. Merrill 24 Aug '11

24 Aug '11

Greetings. The toasters list is moving! As of next Wednesday August 24, the toasters list will be moving from its current address at toasters(a)mathworks.com to toasters(a)teaparty.net. (That domain name was in place long before it had the recent political meaning in the United States!) For those with knowledge of the history of the toasters list, it will be returning to its roots and will be hosted by the founding member of the toasters list. "Why is this happening?" The Mathworks is no longer supporting external facing email lists. "What do I have to do?" On the cutover date, we plan to take the existing member list and use it at the new address, so there is nothing you have to do to un/subscribe. However, after the cutover you may need to update your address books or spam filters for sending or receiving email from the new address (toasters(a)teaparty.net). If you'd like to unsubscribe and not be transferred over, simply send a text-only email (no HTML!) before Aug 24th to the old list address toasters(a)mathworks.com (a majordomo list) with a blank subject and the email body containing the words: unsubscribe toasters end If you would possibly like to subscribe later, simply send an email to the new list address toasters-subscribe(a)teaparty.net (a mailman list) after Aug 24th. If you prefer to maintain your subscription via a web interface, it can be found at http://www.teaparty.net/mailman/listinfo/toasters after Aug 24th. We'd like to point out that the NetApp website hosts a set of communities at http://www.netapp.com/us/communities/; these offer valuable information in addition to the independent toasters mailing list. Sincerely, Toasters List Administrators: Todd Merrill Kevin Davis Tom Yates
