NSF client listing
by Weasner, Matthew K 19 Oct '12

19 Oct '12

This is probably a silly question, but what is the most reliable way to get a list of NFS clients that have an export mounted? OnTap 7.3.3, and the share is exported R/W to the world.

Expand SATA aggregate or buy SAS disks
by James Andrewartha 10 Aug '12

10 Aug '12

Hi, We have a small metrocluster with 2TB SATA disks in DS14mk2 trays, mostly used for VMware. We desperately need more IOPs, and are tossing up another 14x2TB SATA tray, which would have the benefit of just expanding the aggregate, vs 12 of 600GB 15krpm SAS (half a DS4243), which would give more IOPs but be more admin overhead since we'd have to move VMs amongst the shelves. Capacity isn't a problem, and when we built the metrocluster the ATTO 6500N fibre bridge wasn't available, so SATA was our only option at the time. We're getting quotes for both options, but does anyone have an opinion on expanding the SATA aggregate vs setting up a new SAS one?

ndmpcopy from 6.x to 8.1
by Jon Bousselot 23 Jul '12

23 Jul '12

Has anyone used ndmpcopy to migrate volumes from ontap 6.5 to 8.1 without going through any intermediate steps? The 8.1 docs say qtree snapmirror doesn't support source volumes prior to 6.5, so I'm looking for success stories on possible alternatives in case it doesn't work as advertised. rsync takes a long long time, but it works fine. This is all linux data, nfs. -Jon

Getting NFS3ERR_ACCES for NFS Share
by Ray Van Dolson 30 May '12

30 May '12

IBM N6240 running ONTAP 8.0.2P3. Have a number of NFS shares set up with pretty straightforward permissions: /vol/napc2_p2_Data6 -sec=sys,rw,nosuid Filer is connected both to NIS and AD and most shares are shared out via both NFS and CIFS. When attempting to copy file content to the share above (all shares really, but using this one as an example), I get a Permission denied error (packet capture shows this to be an NFS3ERR_ACCES message). The file itself is successfully created, but is size zero. Once the file is created (with error message) I can then run the exact same copy command again and this time the data is populated. Packet capture seems to show the CREATE call succeeding, while the subsequent SETATTR call failing with the aforementioned error. Anyone run into something like this before? NFS client(s) in this case are Linux (RHEL, Fedora). NFSv3 is in use with NFSv4 explicitly disabled. Ray

Install OnCommand Core on Ubuntu?
by Fredrik Pettai 30 May '12

30 May '12

Hi, Earlier I got a tip on how to install and run DFM on an Ubuntu server instead of RedHat / SuSE (http://www.eigenmagic.com/2009/06/26/how-to-install-netapp-dfm-on-ubuntu/) However, I would like to do the same thing with OnCommand Core, but the former DFM routine doesn't seem to work well at all. So, I wonder if someone else has manage to do the same thing with OnCommand Core and succeeded? Thanks, /P

Snapvault stop on 8.1 7-mode
by Jeff Cleverley 30 May '12

30 May '12

Greetings, I posted a couple of weeks ago about snapvault relationships not going away. It turned out the snapvault stop had not cleaned up all the associated snapshots on the destination used for qtrees. Since that time I have had a similar problem on multiple filers. The problem seems to be that snapvault stop doesn't actually do anything in 8.1. I upgraded one of the filers from 8.0.1P1 to 8.1 GA. I was able to get the SV stop to work at 8.0.1, but it hasn't worked once since I've upgraded. One of my other filers is doing the same thing. Ultimately after multiple SV stop attempts (at least 5), rebooting the filer, then doing more multiple SV stops, I was able to get some of them to lose the SV lock. I've got a call open for this but haven't received any useful information from it. This is an example of the error message I get. isolation> snap delete former_mofab isolation(0118075592)_former_mofab_root-dst.0 Snapshot isolation(0118075592)_former_mofab_root-dst.0 is busy because of LUN clone, snapmirror, sync mirror, volume clone, snap restore, dump, CIFS share, volume copy, ndmp, WORM volume, SIS Clone The snapvault stop was the first thing run. Nothing else was done until after it completed. Everything else is cleaned up. The schedules, relationships, etc. A snapvault status doesn't show a source because that has already been cleaned up. The volumes are not part of a mirror and this snapshot is the only special snapshot in the volume. I've also taken the volume offline and brought it back online but that doesn't help either. Is there some magic recipe at 8.1 to make SV stop work? I can't keep rebooting filers and spending 30 minutes per volume doing multiple stops and snap delete attempts.

VSC Privilege
by Carl Howell 30 May '12

30 May '12

I'm trying to get the Virtual Storage Console working using a domain account. Every time I try to log in, it gives me "In order to determine which controller privileges are allowed for this username, the following controller privilege is required: useradmin-user-list" The domain user account I'm using is a member of a group on the filers that has a role with login-*, api-*, and cli-* capabilities. What am I missing? Thanks, Carl

Curiosity killed the NetApp admin: Empty lun not empty
by Peta Thames 30 May '12

30 May '12

Hi all, I have a question born mostly out of curiosity but also slight paranoia. I don't know VMware very well so forgive me if I'm missing something obvious. I have a VMware lun that is thin-provisioned and presented via FC. vSphere reports that the lun has no VMs in it, and yesterday I deleted the datastore from VMware. It was only mapped to one cluster. The lun is currently offline and no-one's complained (yet). On the filer, it reports that the lun occupies 962.9gb of its 1tb. Surely it should be empty? There are no snapshots. We don't use snapmirror. Fractional reserve was set to 100 but I've since set it to 0 and it made no difference. I haven't been here long so I don't know any more history I'm afraid. Any ideas? Thanks, Peta P.S. If anyone was curious about my last email sent to this list re reallocation and de-duped volumes, I can't get a detailed answer from NetApp support aside from "generally, don't reallocate de-duped volumes". So that's what I'm doing (or not, so to speak).

Poor NFS 10GbE performance on NetApp 6080s
by Dan Burkland 29 May '12

29 May '12

Hi all, My company just bought some Intel x520 10GbE cards which I recently installed into our Oracle EBS database servers (IBM 3850 X5s running RHEL 5.8). As the "linux guy" I have been tasked with getting these servers to communicate with our NetApp 6080s via NFS over the new 10GbE links. I have got everything working however ever after tuning the RHEL kernel I am only getting 160MB/s writes using the "dd if=/dev/zero of=/mnt/testfile bs=1024 count=5242880" command. For you folks that run 10GbE to your toasters, what write speeds are you seeing from your 10GbE connected servers? Did you have to do any tuning in order to get the best results possible? If so what did you change? Thanks! Dan

ONTAP & IPv6?
by Fredrik Pettai 29 May '12

29 May '12

Hi, IPv6 support in ONTAP has be there for a while, but is anyone really using it? and in production? I asked NetApp (the local Swedish office in Stockholm) and they tried to asked both their integrators and internally in NetApp worldwide to see if anyone knew about any customers running ONTAP and IPv6 enabled, but only got "no" as answer or no feedback at all. That was disappointing... So does anyone on the list run IPv6 on their NetApp(s)? or know of any other NetApp customer that enabled IPv6? We're starting to use it (on ONTAP 8.1 GA), but it would be comforting if we where not the only ones using it... Thx, /P
