Verify SME snaps -- yea or nay?
by Andrew Laurence 11 Feb '14

11 Feb '14

For those running Snap Manager for Exchange... do you verify the snapshots? We've been running Exchange on filer iSCSI luns for several years, dutifully verifying our snapshots and dealing with the added IO during verifies. We're currently in process of setting up mirrors to a remote filer, with the intent of running the verifies on the remote filer. I heard in conversation, however, that verifies have fallen out of fashion. Is it that the snap process has so little error that there's no point in running verifies? Are verifies obviated when running in a DAG? Thanks for your thoughts,

What triggers raid.disk.copy.threads changes?
by Jeff Cleverley 10 Feb '14

10 Feb '14

Greetings, I've noticed that periodically the raid.disk.copy.threads option gets changed on my filers. It appears this gets turned on when disk problems occur. Once a disk is rebuilt/failed/replaced, the option goes away. I've noticed that I current have this running on one of my heads fro almost 2 weeks now. The disk has been replaced, aggr status -f/m report nothing, The vol and aggr status show everything as online with no redirect type messages. There are no new disk related messages in the messages, audit, or ems log files. Is there a way to figure out why this option is still showing up and potentially reset it? Thanks, Jeff -- Jeff Cleverley Unix Systems Administrator 4380 Ziegler Road Fort Collins, Colorado 80525 970-288-4611

Constrained Access Model
by Ray Van Dolson 10 Feb '14

10 Feb '14

Have an internal requirement to set up some file share space that is fairly restricted. While we can isolate access of course with ACLs (AD environment), we're also looking for a way to generate access reports for the data. The users would also like to restrict the ability to copy the data (though OK to view). The last one sounds like a non-starter to me. :) The ability to report on all ACL change activity would also be nice (though maybe could find some 3rd party tool for this). Am thinking that we could use fsecurity to enforce permissions (not allow someone to override) and explore CIFS audit logs to generate reports on access. Perhaps there is a slicker approach though or some pre-existing tool that would make at least the access reporting easier (assuming turning on CIFS auditing would generate some overhead). Thanks, Ray

OSSV / SnapVault Newbie - Scheduling an automatic update.
by Ray Van Dolson 04 Feb '14

04 Feb '14

7-Mode ONTAP 7.1.2P4 as a secondary system and OSSV on Windows as a primary. I have a relationship established and have been doing manual, periodic "snapvault update"s to bring across changes. I want to schedule this, but I'm not sure that snapvault snap sched is what I'm after or not. It seems to be about retaining snapshots of data and really I just want to keep one copy -- as up to date as possible (once an hour or so). We're preparing for a migration. Maybe I do something like: snapvault snap sched -x <vol_name> hourly 1@mon-fri@0-23 ? Thanks, Ray

Random/Sequential measurement on Filers
by Martin 24 Jan '14

24 Jan '14

Hi, I'm trying to characterize the workload on our Netapp Filer running VMware over NFS and iSCSI for benchmarking purposes using IOmeter. Is it possible to determine what the percentage random sequential distribution the workload is on a Filer e.g from a perfstat? I've looked at vscsiStats but that is only per VM and not for the aggregate workload on the Filer. -- View this message in context: http://network-appliance-toasters.10978.n7.nabble.com/Random-Sequential-mea… Sent from the Network Appliance - Toasters mailing list archive at Nabble.com.

flow control and 10g interfaces - ifgrps and vlans
by Jordan Slingerland 22 Jan '14

22 Jan '14

Can flow control be disabled on a vlan interface? I tried in a simulator and It spits back "SIOCSFLOWCONTROL - Operation not supported by device" In the same simulator I can enable or disable it directly on the interface. Example RC: hostname toasterA ifgrp create lacp nfs_ifgrp -b mac e2b e1b vlan create -g off nfs_ifgrp 100 ifconfig e0M 192.168.1.100 flowcontrol none netmask 255.255.255.0 partner e0M up ifconfig nfs_ifgrp-100 192.168.0.100 flowcontrol none netmask 255.255.255.0 mtusize 1500 partner nfs_ifgrp-100 trusted up nfo route add default 192.168.0.1 --Jordan For the seventh consecutive year, Independent Health was named one of the best companies to work for in New York State.
