Continuously available CIFS
by s.eno 13 Mar '19

13 Mar '19

Hi, Does anyone here utilize continuously available CIFS shares for anything other than Hyper-V and/or SQL? If so, do you have real-world results on how those shares do during ONTAP upgrades? I need to perform upgrades on a 4-node cluster and have a mission critical application that doesn’t like it when the takeover/giveback process severs its CIFS sessions. I’m trying to figure out a way to do this without causing downtime to the application which in-turn causes push-back on the upgrade plan. The application appears to be connecting to the shares via SMB3_1, so it should support CA, right? I’ve tested checking the CA box on one of its shares and the app drains connections to the share and stops sending any more traffic, so it appears to not like something related to that change. One of its shares, however, was provisioned with that box checked and that one works just fine as far as traffic & sessions go. -- Scott s.eno(a)me.com

VMware datastore stats integration
by Ian Ehrenwald 11 Mar '19

11 Mar '19

I think I know the answer to this already (which is NO) but maybe I'm missing something not so obvious. Is there a way to insert into vSphere some storage statistics from NFS datastores on a per-VM basis? Eg, I want to see that VM prod-xyz is using 3924 IOPS and has 18ms write latency, and I want to see it through the single pane of glass that is vCenter Server in the VM specific statistics. I'm going to guess that the answer is no, not without some sort of plugin to vCenter that talks to an ONTAP API and tracks operations on a file level, keying from the VMDK path(s) in the VMX file. I'd also love to see those stats extended to per-VM physical and logical disk space utilization. I have no idea if those sort of stats are even available, and if they were, I would hope that someone on the NetApp side of the equation would have done this already as part of VSC. It would make reporting to management a lot easier. Just throwing it out there..

Alright – with regards to Chris‘ question: I did assume that a0a currently is not LACP or connected to a different set of switches, which is probably the reason, why you cannot just add the physical ports in a0b to the existing ifgrp a0a, right?

Azure CVO and CPU
by SE 06 Mar '19

06 Mar '19

Hi, Is anyone here using Cloud Volumes ONTAP in Azure? I’m trying to figure out why it is the Azure dashboard claims our CVO instance is always running at 100% CPU, but if one ssh’s to the virtual appliance and does a sysstat -m on the node it shows all cpus at 0%-1%. Any ideas on the discrepancy between what Azure sees and what ONTAP claims? — Scott

vol move throughput throttle
by Mike Thompson 28 Feb '19

28 Feb '19

did a throttle to volume move throughput throttle ever make it into ontap 9? I see there was some discussion about this on the list a few years back, with the consensus that it was a known desire to have a throttle in there, and someday maybe it would make it in. I see there is a throttle on the number of concurrent moves, but don't see anything specific to throughput rate.

environmental control?

11 Feb '19

Hi list, does anyone know if there’s an official shutdown temp for a 3270 FAS in HA 7-mode? I can see the operating temperature list, and have wandered through the environment settings, and first impression is that it’s a function of inflow temp being too high, and possibly two other subsystem reporting too high, for environmental shutdown to occur, but that’s just guessing :) I’dreally like a link to a doc that says “w3270’s shutdown at 54 degrees celsius” or similar…….

Hide Snapshots from NFS clients
by Sebastian Goetze 04 Feb '19

04 Feb '19

Hi All, I'm teaching a SMB/NFS combo at the moment, and the question again came up, how to hide ".snapshot" from NFS users/scripts (like in the 7-Mode days). In the Man Pages I found *[ -v3-hide-snapshot {enabled|disabled} ] - Hide Snapshot Directory under NFSv3 Mount Point* This optional parameter specifies whether to hide the .snapshot directory while listing under NFSv3 mount points. However an explicit access to the .snapshot directory will still be allowed even though the option is enabled. The default setting is disabled at the time of creation. (I checked, it's not in 9.4) Greetings from Munich Sebastian NAI (NetApp Instructor) _________________________________________________ Jeremy asked Feb 5, 2016: In 7-mode we are able to make snapshots accessible, but invisible to NFSv3 clients. In this mode there is a .snapshot directory, but if you ‘ls’ that directory it appears empty. However, if you ls .snapshot/hourly.0 say then you can see that the snapshot is in fact there. We now have an 8.3.1 CDOT filer and have not been able to work out how to reproduce the behaviour. The snapshots are either accessible and visible (which causes problems for programs which walk the tree) or not accessible at all.…
