administrivia: GDPR
by Tom Yates 29 May '18

29 May '18

This list was originally run by majordomo, and then by mailman. No-one got on this list without asking to be there. You all get emailed every month telling you how to get off it, and on the odd occasions people can't work it out from there I remove them on request. I am not fannying about requiring everyone to re-opt in. The exception to this is people who are subscribed via exploders. I don't approve of exploders, since they give me a headache, but I don't actively hunt them down and remove them. They, and their GDPR implications if any, are the problem of those who run the exploders, not me. Me, my wife (who is co-sysadmin on the hosting box), and Kendall Libby (being co-list-admin) have access to the subscriber list. We won't be telling anyone who's on it. If anyone needs further clarification, email me. While I'm sending this out, I should mention that I have enabled automated message-wrapping from people whose ISPs have, in their infinite wisdom, decided to enable DMARC reject or quarantine policies. People from those domains who post will now get their message "wrapped" in a digest from the list itself. When replying to the senders of list messages, have care to check the sender's email address in case it turns out to be the whole list. I'd hoped DMARC would go away, but no such luck, so this seems least dreadful. ** If for some reason any of this turns out to be contentious, please start with me before discussing it on-list. ** -- Tom Yates - http://www.teaparty.net

It was about 100€ for a shelf, if I remember correctly, so we didn't mind the 20% that were dead/unusable... A zeroed, unassigned disk should automatically be reformatted with the correct WAFL version, by the way. Up or down. So no worries there with disks from newer ONTAP versions...

Restrict VSC to a Subset of SVM's
by Philbert Rupkins 22 May '18

22 May '18

Hello Toasters, Our ontap clusters contain a number of SVM's. For purposes of this post I'll classify our SVM's into two broad categories: * SVM's that host storage resources for our ESXi clusters * SVM's that do NOT host storage resources for our ESXi clusters We initially direct connected VSC to the SVM's hosting VMware resources. As documented by NetApp, this resulted in VSC provisioning volumes (NFS datastores) then mounting them via indirect paths (our SVMs have multiple lifs). We dont want datastores mounted via indirect paths, nor do we want to deal with the other limitations associated with direct connecting VSC to SVM's. Now, AFAIK, the only option we're left with is connecting VSC to the cluster management LIF. The catch is we only want to allow VSC privileges to manage the SVM's hosting VMware resources. VSC should not have privileges to the non-Vmware related SVMs. Is there a way to connect VSC to the cluster management LIF while only allowing VSC the ability to provision storage to and manage a subset of SVM's on the cluster? We're currently running VSC 6.2.1 and ONTAP 9.2P2. -Phil

Re: moving CIFS shares

We've had good luck with a 1:1 ratio of volumes to shares since the platform limit is 1000 volumes/node on most recent hardware. With that model, you can shuffle volumes (and thus shares) between aggregates online with vol move, and you get easy access to goodies like QoS. We have about 1300 shares at the moment. More volumes is not manageable IMHO. For example, an altavault restricts snapmirror to 100 volumes. We already have more volumes that that. Regards, pdg

moving CIFS shares
by Peter D. Gray 08 May '18

08 May '18

Hi people, Background: we have 20 odd volumes for fileshares. We limit the size of the volumes to 10T. When a volume gets near full, we need to shuffle shares to new volumes or volumes with plenty of space. Does anybody have a magical solution for moving fileshares between volumes? With minimal but not necessarily zero downtime? Obvious solutions are: 1) Down share, copy share to new volume, up share 2) Down share, clone volume, up share on new volume, split volume, cleanup mess. I was wondering if anybody has seen a system to proxy the share and move it in the background. I have seen this work with NFS shares but not with CIFS. Any magicians out there? Regards, pdg

Anyone else have to wait 1-3 minutes after logging into support.netapp.com staring at a white screen before you can do anything? Asking for a friend. K-thanks.

Attack of the Zombies
by Ehrenwald, Ian 27 Apr '18

27 Apr '18

Is anyone familiar with messages such as these, and how to diagnose what volume(s) on what aggregate is triggering it? 4/27/2018 11:24:31 node1 NOTICE wafl.zombie.susp.msg.threshold: WAFL(R) is experiencing zombie throttling possibly due to requests for large number of file deletions. This can be mitigated by a combination of a) reducing the load on the system, b) issuing the file deletion requests in smaller batches and c) increasing the limits to allow more zombies to be queued on the system (Please contact technical support). I'm troubleshooting a latency/performance issue and this caught my eye in the event logs. Web searches aren't really coming up with anything useful and there is mention of it in the NetApp KB but no real background information or troubleshooting steps. Also, the (R)egistered Trademark after WAFL in the notice is weird to have in a technical event log.

Windows Host Utilities for Server 2016
by Alexander Griesser 18 Apr '18

18 Apr '18

Hey there, does anyone know when we can expect working Windows host utilities for Server 2016? The current release (7.1) refuses to install due to a broken dependency check on hotfix 2796995. Also DSM MPIO 4.1P1 for windows refuses to install because of a broken dependency check for Powershell 2.0.

Hello, Is there a way to see the changed/deleted files that are taking space in snapshots? (7 Mode, 8.2 NFS/CIFS access.) Thanks.

NDMP dump dates
by Edward Rolison 05 Apr '18

05 Apr '18

I've been trying to find how this is done for CDOT, and keep on running into 7-Mode references. I'm using NDMP to take backups of volumes. How can I tell what the NDMP reference 'dump date' is? Is it written to a file somewhere? (e.g. like /etc/dumpdates) Thanks and regards, Ed.
