RE: CIFS overhead with Netapp Filers
by Paul Keating 28 Mar '07

28 Mar '07

I assume, in both cases, you're doing the test, right after a clean reboot of the Windows server or filer? ie, you're reading from the disk and not from cache? Are you reading from a similar backend disk subsystem in both cases?

Let's say for instance a Windows Server to Windows Server transfer on the same switch, same subnet, GIG copper interconnects, no TOE card, etc gets me up to about 50% utilization (500Mbps). Should that same server to a Netapp Filer see a 20-30% degradation in TX/RX speeds because of CIFS overhead? What should I expect for data rates in this type of scenario? Are there any tweaks anyone knows of to decrease this gap?

Method to exercise tape drive?
by Darren Dunham 28 Mar '07

28 Mar '07

Sometimes when troubleshooting backups I want to see if the host can drive data to a tape drive at high speed without involving a filesystem or backup software or the like. I've got some slow NDMP backups on some filers that have fiber-attached LTO-3 drives. At the moment I'm assuming that the contents of the filesystem make it difficult to drive the tapes at high speed, but it would be nice to have another data point that would show that the local drive is or is not behaving properly. Is there any way to have the filer send data to the drive without actually invoking an NDMP backup or running a 'dump'? On another host I might mount a scratch tape and run 'dd if=/dev/zero of=/dev/tape' with an appropriate block size and count. I see a 'dd', but I don't know of a data source like /dev/zero. Is this or something similar possible? Thanks. -- Darren Dunham ddunham(a)taos.com Senior Technical Consultant TAOS http://www.taos.com/ Got some Dr Pepper?

NFS File locking between Linux/Windows
by masterblaster 28 Mar '07

28 Mar '07

Hi everyone, currently we have a problem with file locking between Linux and Windows. We use shared access via NFS to files on a FAS3050 filer from Linux and Windows clients. We noticed that file locks, which are set by Linux, only apply to Linux clients and file locks, which are set by Windows, only apply to Windows clients and not vice versa. Question: Is it possible to lock files via NFS from Linux in that way that the files are also locked for Windows client and vice versa (i.e. for OpenOffice Documents) ? Environment: - Netapp Filer FAS3050 with Ontap 7.1.1.1 - Linux NFS Client (Suse 10.0) - Windows XP NFS Client (NFS Client: Microsoft Services for Unix) - Windows NT with Maestro NFS (from Hummingbird) Test programs: - Linux: "flock" command - Windows: "locktest.exe" We don't need byte-range or oplocks ! Just the whole file needs to be locked. Any ideas ? Thanks in advance. -- View this message in context: http://www.nabble.com/NFS-File-locking-between-Linux-Windows-tf3452921.html… Sent from the Network Appliance - Toasters mailing list archive at Nabble.com.

Re: how to obtain patch releases
by Chris Thompson 27 Mar '07

27 Mar '07

Mention of patch releases prompts me to vent spleen about the following... If you exercise NOW to fetch ONTAP 7.1.2 you end up at http://now.netapp.com/NOW/download/software/ontap/7.1.2/download.shtml which looks fine until you realise there's no reference to checksums for the files you are about to download. Mystified, I tried 7.1.2P1 instead, which ends one at http://now.netapp.com/NOW/download/software/ontap/7.1.2P1/download.cgi which has the expected link to a checksum page. So although I didn't need any of the fixes in the P1 version, I decide to use that instead. Later, it occurred to me to look at http://now.netapp.com/NOW/download/software/ontap/7.1.2/download.cgi which does have a link to the checksums for the 7.1.2 files. But by then, it was too late ... [In case you are wondering, I am not avoiding 7.2.x because of the problems described by various toaster-posters, but because I am stuck with an F800 series filer.] -- Chris Thompson Email: cet1(a)cam.ac.uk

RE: Drive cleaning
by Todd Kofchur 27 Mar '07

27 Mar '07

" Now, LTO technology has a variable speed head which speeds up and slows down relative to the speed of the tape passing it. This removes the shoe-shine affect seen in DLT drives." This does not completely remove the possibility of shoe-shine. All tape drives must maintain a minimal speed to write data to the tape and they will NOT be able to go below this threshold. If your network is slower than this minimal threshold you will get shoe-shining even with variable speed heads. __________________________ Todd Kofchur President Penaria Technologies, Inc.

They are a fixed length of tape which is used to calibrate the gearing of drives when an error occurs. For instance, a DLT drive needs it's head spin speed to be synchronised with the speed that the tape passes it as the tape needs to move at a constant speed. If too many errors occur, a DLT drive will ask to be "cleaned". Now, LTO technology has a variable speed head which speeds up and slows down relative to the speed of the tape passing it. This removes the shoe-shine affect seen in DLT drives. I have never seen an LTO drive require "cleaning" as they tend to always be in sync. Take from this what you will, but I'd rather use the space in the library for data. If an LTO drive asks for cleaning, it has issues!!!

We currently are running OnTap 7.2.0 and not having fun with it. 7.2.1 contains many important fixes, but 7.2.1P1 has some critical fixes as well. I am getting fed up waiting for the next GA release, and I am willing to take the risk of running a patch build. The only problem... I cannot figure out how to download it! In the past I have found patch release download links in the NOW KB when referencing a related bug number... not so this time. Anyone know how to get the binaries? Open a support case? Bribe a NetApp tech? Thanks, -Greg Mackinnon University of Vermont

RE: Drive cleaning
by Paul Keating 27 Mar '07

27 Mar '07

The STK libraries only require them if you're using library based cleaning. If you're using tape alert, or otherwise using Netbackup controlled cleaning, you can make any tape ID a cleaning tape......then using "CLN" labels is only a Really Good Idea (TM). Also, Tape alert does not work (or didn't, last I heard) for Filer attached drives. Any tape drives connected to an NDMP device must be cleaned manually, or on a "frequency based" schedule, as the NDMP devices do not know what to do with the received tape alert message, like a Netbackup media server would. You could use Library based cleaning, but that must be turned on for all drives in the Libary, and frequently causes problems with Netbackup. Now back to your problem. If the media were "discovered" by Netbackup, and they didn't have a barcode rule defined for them, they were probably placed in the "DEFAULT" media type, which is probably HCART3. In that case, you need to change the cleaning tapes to media type "HC3_CLN", and make sure the "number of cleanings remaining" is set to a value higher than 0, Volume Pool is set to "None". However it is much easier to define your cleaning tapes before you inventory the robot, as you can't change the media type in the GUI for an assigned media cart.

ISCSI Issue and VMWare ESX 3.0.1
by Justin Brodley 22 Mar '07

22 Mar '07

I'm currently dealing with a problem on several of our ESX IBM LS21 Blades when trying to attach to ISCSI Luns on the Netapp FAS 3020's. Our Netapp currently connects to two separate physical networks to deliver ISCSI connectivity. The ESX support folks are telling us that the netapp presents both ISCSI interfaces to the server. Initially the ESX box connects on the correct interface, but then after a few hours it attempts to try the other IP address and fails and disconnects the entire VM Host from the Netapp, despite the fact that the network never went down. We have several Windows 2003 servers with ISCSI initiator that don't have this problem on identical hardware and chassis. I assume that either ESX's iscsi initiator is badly designed, or MS has broken some industry standard spec. To rearchitect our storage network will take significant investment on our part, and we'd rather come up with a way to fix this either by pushing on ESX to fix the initiator or finding a way to have the Netapp only send one IP address back to the initiator. Is there any way to resolve this from the Netapp perspective? Thanks in advance. -Justin

Vol copy will copy a volume's contents and the snapshots as well, but it won't work between traditional and flexible volumes. Since you have space for both the traditional volumes and the aggregates, could you just not migrate the volumes contents to the new volumes and start snapshotting there, and at the same time retain the old volumes for a period of time until you don't require the old snapshots anymore.

FYI, new hot-fix: Snapshot volumes do not mount successfully or the volume dismount operation reports an error when you use a Network Appliance storage device with the Windows Server 2003 Virtual Disk Service http://support.microsoft.com/default.aspx?scid=kb;en-us;931300&sd=rss&spid=…

move snapshots
by Scott, Tom E 21 Mar '07

21 Mar '07

List, We have a FAS270 recently upgraded to 7.0.5. We would like migrate from traditional volumes to flexible volumes and keep the existing snapshots. I searched the NOW site and could not find much, has anyone done this? Will we be able to retain the existing snapshots?? We have enough drives to have the aggregate and traditional volumes working simultaneously on the same filer. Cheers. Tom.

RE: FAS3020 - aggr best practises.

You can always go with a larger RAID group size - it does support up to 28. However, at some point you have to bite the bullet and lose 2 more disks to parity. It depends on how you want the math to work out in the long run. The reason you want to add the disks in large sets is so you have a more level writing of the data to the disks - you don't want to get 3-4 'hot disks' slowing the whole aggregate down until the data is spread evenly among the aggregate.'s new disks... -----Original Message----- From: owner-toasters(a)mathworks.com on behalf of Sphar, Mike Sent: Mon 3/19/2007 11:06 AM To: toasters(a)mathworks.com Cc: Subject: RE: FAS3020 - aggr best practises. Point one reminds me of a question I've been pondering. I've got a filer using RAID-DP with 3X14-disk raid groups, and currently 7 spares. Ideally I'd only keep two spares, but I'm still not clear on the pros/cons of adding a 5 disk raid group, effectively only adding three more data disks to the volume. I'm not in a space crunch currently but I certainly will be at some point. Is it best to leave so many extra spares until I can add a full raid group all at once? Or in my case is it not that important? -- Michael W.

Hi Darish Welcome to NetApp and to Toasters! 1. You can do an "aggr add aggr0 56" or use the FilerView GUI and add all 56 of the new disks into the existing aggregate. You can physically add the shelves and add them to the aggr while the filer is up and running. I see no disadvantages, and that is the best practice. (Add disks in large sets, ideally the raid group size).

Throughput on 3020
by Knut Kristan Weber 19 Mar '07

19 Mar '07

Hello, this is my first posting to this list. A customer of us has a NetApp 3020 with 3 S-ATA shelfes each filled with 500 GB disks. He has a trunked 2*1 GBit network connection. He has 3 volumes, each volume resides on a different aggregate built from the disks of one shelf each. Via NFS he gets a perfomrance of sustained 60 MB per second with large and small files. Only one connection used during the test, no aditional traffic on the system and network segment. He expected the performance to be "much" better. Besides any possible calculations - what´s the performance he can expect in real world practice under best circumstances? ------------------------------------------------------------ with kind regards ______________________________________creating IT solutions Dipl.-Chem.

new scrub feature...
by tmac 19 Mar '07

19 Mar '07

Not sure how many know about this, but kind cool We all know that scrubbing usually takes place at Sunday@1am There is a new option: raid.scrub.schedule Not sure when it came into being, but here is a valid use: 8h@mon@22,8h@tue@22,8h@wed@22,8h@thu@22,8h@fri@22,18h@sat@6,24h@sun@0 This schedule allows the scrub to run for 8 hours, mon-fri starting at 10pm. It also allows the scrub to run all day sat & sun. This is good for my environment, manipulate it to work with yours. The man page says that if a #m or #h is specified, then it overrides the default scrub duration option. As a precaution, I changed mine to 8 hours (from -1, which means run until completion) Not sure how well it works, I just tried this this morning. My FAS980 scrubs all finish before I get in Mondays. My R200s though usually run until about mid-day or late afternoon on monday. I will let you all know if it works next week.... -- --tmac RedHat Certified Engineer

FAS3020 - aggr best practises.
by Darish Rajanayagam 19 Mar '07

19 Mar '07

Greetings: I am new to the NetApp world and am looking for some advice/guidance. We purchased a NetApp 3020i with two shelves (10K 144GB FC drives) a few months ago. We have now placed an order for 4 additional shelves (fully loaded) with 10K 144GB drives. The current configuration is one large RAID DP Group with 1 HotSpare (27 Disk DP RAID Group), which belong to one aggregate (aggr0). My question: 1. The new enclosures, should I create 2 x 28 Disk DP RAID groups and add it to the existing aggregate? The application we run is IO intensive and more spindles the better. Does anyone see any disadvantages of doing the above? 2. Does anyone have a formula to calculate mean time to Repair on the 10K 144GB disks on a busy filer? I only have one hot spare disk, should I add more, is there a rule of thumb? 3. We currently have multiple volumes on the filer, after adding the new shelves/spindles, if I run a reallocate on the existing volumes, would it take advantage of the additional spindles. Any help/guidance greatly appreciated. Thanks, Darish.

FAS270: DOT on SATA disks possible?

Hi, I have a question regarding SATA drives in a FAS270. Is it possible to use a FAS270 with just 14x500GB SATA drives in an expansion shelf and run ontap on the sata disks? Or do I need 3 FC Disks as well for ontap? thanks in advance, Alexander -- Mit freundlichen Grüssen | Kind regards, -- Alexander Schalek Bacher Systems EDV GmbH - Technical Services Clemens-Holzmeister-Strasse 4 A-1100 Wien, Business Park Vienna phone: +43 (1) 60 126-34 | fax: +43 (1) 60 126-4 e-mail: as(a)bacher.at | http://www.bacher.at NetApp Certified Expert | Sun Certified Professional

More Auditing File Contents Questions....

Toasters; I'm currently using "treesize pro" to help me understand what kinds of files are being stored on my filer by the users. It's a good windows- only app that gives all kinds of good info. Do others of you out there have any good recommendations for how to do reporting on files, space reporting, etc. on your filers? Thanks; JKB

Auditing CIFS shares for compliance purposes
by Skip Norman 16 Mar '07

16 Mar '07

I am currently faced with having to provide which users have access to what directories within our CIFS shares on our 270 and 3020 filers. The only auditing that I have been successful with thus far is pulling success and failures of access to the shares using the cifs.audit.enable option and then viewing the event log via windows. Has anybody else been faced with having to provide a log of who has access to what directories? I would imagine that I am not the only one that has come across this...Any help would be greatly appreciated. I am using Ontap 7.0.5 if that helps. Thanks, Skip

Hi Toasters, we have a database on nfs space and i wonder about the output of nfs_hist. v3 read: 35280016 (blocking requests) - millisecond units 0 1 2 3 4 5 6 7 17347681 2028005 655821 757932 1061542 1463375 1943351 1721450 <16 <24 <32 <40 <48 <56 <64 UNUSED 6417253 1334072 338371 111465 43542 18991 10063 0 <128 <192 <256 <320 <384 <448 <512 UNUSED 20806 2364 1282 617 526 280 266 0 <1024 <1536 <2048 <2560 <3072 <3584 <4096 UNUSED 723 158 77 3 0 0 0 0 <8192 <12288 <16384 <20480 <24576 <28672 <32768 UNUSED 0 0 0 0 0 0 0 0 <65536 <98304 <131072 <163840 <196608 <229376 <262144 >262144 0 0 0 0 0 0 0 0 Is the amount of read-calls with a RTT greater than 7ms ok, or is it something i have to wonder about?? I mean, the calls between 7-16ms are about 18%. But on the other hand nfs_hist shows only the blocking requests so the percentage of total calls will be even less than 18%. Does my nfs_hist look like a healthy system or do i have a problem? Regards and thanks for every answer :D Jochen
