Quota CPU hog with Ontap 7.0
by JONES P.S. 21 Feb '07

21 Feb '07

We've just upgraded our main filers to 7.0.5 after running 588 days with no interruption on 6.5.5. However we've run into serious problems when enabling quotas. The system runs at 100% for ages and we eventually have to disable quotas altogether. On the old system it took about 1 hour and 20% CPU to initialise quotas so there's an enormous difference. The system is unuseable if we enable quotas on 7.0.5. Netapps haven't been much help; the articles they refer me too mention this problem but in all cases the bug notes claim its been fixed in 7.0.5. Anyone been here before me? We have ~20,000 accounts but most are captured with default quotas although we have around 1000 explicit entries defined in the quotas file. Thanks ...

RE: Large Oracle database question

I agree with your thoughts on performance but not the use of large raid groups. It would eat into the data spindle count but I think 10 disk RGs would increase the warm fuzzy feeling. I have pushed single parity RGs well past the safe point without problems but the guy is antsy about failures. I have never lost any data in the years I have been taking care of the filers. The plan right now is to use what comes with Solaris for filesystem management. VxVM was thought of for a while.

F760 memory spec
by Ronan Mullally 19 Feb '07

19 Feb '07

For sheer geek purposes, I've got an old F760, long out of warranty, in my garage. One of the DIMMs has developed a fault and I'd like to replace it. Does anybody know what the memory spec is? The DIMM is branded Samsung KM48S16030BT-GL. From what I can gather it's 168 pin 256MB SDRAM, but I don't know what speed (PC-100? PC-133?), and given that it's got 9 chips on it, it's ECC. Is the filer fussy about the memory it will accept? Do I have to replace this with identical memory, or will a pair of similar DIMMS do? -Ronan

Large Oracle database question
by Miller, Michael CTR USTRANSCOM J2 16 Feb '07

16 Feb '07

(This might show up twice) We are getting ready to stand up a 30+TB GIS app and I was wondering if anyone on the list has done something like this on a filer. The guy who will be running this doesn't think a filer would give him the performance required (not specified) and is also concerned that the parity drives will get beat to hard. He has been told by others that the only way to make this work as needed is to use RAID 1+0. This started out being required for all of the data but has been relaxed to just the indexes and current point of interest data. Any thoughts?

BayLISA meeting tonight - Feb 15 7-10pm NetApp HQ Sunnyvale
by Jennifer Davis 16 Feb '07

16 Feb '07

I know this is late notice, but I forgot that there might be people interested on this forum in this talk. If you are interested, make sure to RSVP: http://www.eventbrite.com/event/46941403 We will be recording the meeting, so if you can't make it in person you can always watch the video recording after the fact. The February General meeting will be held at NetApp HQ. Location: Network Appliance HQ Building 1, Founders' Theater 495 E Java Dr Sunnyvale, CA 94089 Time: 7:00-10:00pm Architecting a Resilient Storage System Steve Strange, NetApp Engineering The job of a storage engineer is to find ways to turn a collection of unreliable disks into a resilient system. In this presentation, NetApp engineer Steve Strange shares his perspective on some of the core technologies that help make NetApp systems reliable and easy to manage. In particular, Steve will discuss the NetApp RAID-DP implementation.which carries no significant performance penalty.versus traditional implementations of RAID-6, as well as other alternative approaches to storage problems. Steve Strange has been a member of the NetApp engineering team for nine years and has worked on numerous resiliency projects including the launch of NetApp's first clustered failover product, the rearchitecture of the RAID subsystem, and the development of SyncMirror. Case Study: Decreasing Data Center Power Utilization Devinder Singh, NetApp IT Architect In a recent upgrade of its corporate datacenter, NetApp IT reduced the physical footprint of its storage by 40% and cut power consumption by up to 75% while doubling performance. All told, the project touched 165 different applications (with as many as 8 environments each), 343 servers, and just under 5000 mounts. In this presentation, IT Architect Devinder Singh describes the reasons for the upgrade, the migration methodology, and the results.

High disk reads but low network out
by Paul Letta 15 Feb '07

15 Feb '07

I have been having some performance issues on my F880 the past couple of days. Specifically, an NDMP backup that normally takes 2 hours to complete was stuck in the mapping phase for 12 hours before I killed it. What I am seeing is a high disk read, but without a corresponding network out. Here is a sysstat: > CPU NFS CIFS HTTP Net kB/s Disk kB/s Tape kB/s Cache > in out read write read write age > 62% 1456 6 0 794 16954 46326 0 0 0 4s > 56% 1418 0 0 597 13689 36506 0 0 0 5s > 64% 1737 3 0 867 17637 43572 0 0 0 5s > 53% 1135 18 0 572 14823 42905 1155 0 0 4s > 73% 2067 20 0 1282 37835 69880 6347 0 0 4s > 69% 2031 24 0 1267 38868 67632 0 0 0 4s > 74% 1921 3 0 1027 26644 50881 7778 0 0 5s > 59% 1459 0 0 774 18843 41313 0 0 0 6s > 60% 1212 2 0 665 16391 38766 0 0 0 7s > 54% 1028 19 0 509 11873 33960 0 0 0 7s > 61% 844 302 0 571 13765 39032 0 0 0 7s > 72% 1164 598 0 1870 16750 39968 0 0 0 5s > 71% 948 640 0 8961 9788 29552 0 0 0 5s > 79% 1297 603 0 24157 5831 26034 0 0 0 4s > 87% 2130 465 0 23581 9794 31269 0 0 0 2s I don't know why the disks are reading so much without it going out the network.

RE: High disk reads but low network out
by Glenn Marsh 14 Feb '07

14 Feb '07

The problem may not be due to a full nisk and/or the lack of contiguous space. It may be due to the type of data on the filer and that your filer may not have enough cache memory. We have cache age issues but we have been having increasing problems with large files (larger than 1GB and some well over 10GB) and the creation of directories with large number of entries (directories with thousands of sub-directories and files). Both of these can cause the cache age to get very low. The real problem occured for us when we added a lot of high end Linux boxes with Gigabit Ethernet connections that really pound on our filers. The only fix is to upgrade to a filer with more cache memory. See Bug ID 3986, there is no fix and if you contact NetApp they will suggest the upgrade.

RE: High disk reads but low network out
by Glenn Dekhayser 14 Feb '07

14 Feb '07

Look at your cache age. It's very low, meaning that you are not serving data out of memory, only directly from disk. As the cache age does down, see that your network out numbers go down as well. When your filer gets full, it isn't able to find contiguous space to write data to (thus write 'anywhere'), so it starts breaking things up and you lose temporal locality, which eliminates the benefits of Netapp's read-ahead caching mechanism, thus low cache ages and poor performance. That's probably what's happening. You should think about a wafl_scan reallocate when the system utiliziation goes down, or getting a bunch of data off the box.

Snap Manager for SQL / SnapMirror issue.
by Rod Newcomb 14 Feb '07

14 Feb '07

Help! We have a SQL Cluster, running Server 2003, Snapdrive 3.2r1 and Snapmanager SQL 1.5 On node one, we have an sql instance that runs that Snapshots/Snapmirrors the SQL data over to our offsite location twice a day. Works like a champ. On node two, we have a new instance running all the same software, the backup runs and complets with no issues, but for some reason it will not snapmirror. From the logs, it looks like it doesn't even try. There are no errors. On the node that works, we get the following in the backuplogs: *** REQUEST SNAPMIRROR UPDATE AFTER BACKUP *** Starting SnapMirror update... Querying disk list for SnapMirror update...

I've been fighting this for five days. Netapp support is trying to help, but we're getting no where fast. Rod Newcomb

I've actually used the vol and aggr rename commands frequently, not in the process of migration. My current environment was\has been in disarray before my arrival and I'm trying to go back and standardize and clean up some things. That said, in the pretext of migration, perhaps it should be an optional thing to rename the exports/shares?

In my opinion, Netapp should NOT be renaming CIFS shares when you change volume names. They do this automatically without warning you or logging. I know they're doing it because they think they're being helpful; but really the only time I can forsee changing volume names is if you're doing a migration like you're doing. VERY frustrating indeed. I found myself having to document all the existing shares, and write a script that deletes, then re-creates all the shares and their permissions on the new volume. Hours of work. Netapp, is there a way to disable this "feature" prior to renaming a volume?

But this night I tried to move the data (shares / lun's / exports) from the old /vol/vol0 (trad) via "ndmpcopy -l 0 /vol/vol0 /vol/vol1" and some hour later, "ndmpcopy -l 0 /vol/vol0 /vol/vol1". Everthing was copied. All Clients where offline, and than I renamed /vol/vol0 -> /vol/vol0old and /vol/vol1 /vol/vol0. Because I thought than after the reboot all shares and luns and nfs-exports are back on /vol/vol0 but now on the new DS14. Well I failed, I found out that the vol rename also renamed the CIFS Shares Paths and also the LUN paths. So the CIFS clients where still reading from the old FC9 (/vol/vol0old now) and the iSCSI clients where too. Because I did't terminate CIFS and NFS and iSCSI. To be honest, cool renaming feature to prevent stupid germans from losing data ;-) So, I though be smart forget about the LUNs, they are fine, care about the shares. "CIFS terminate" and replace vol0old -> vol0 in the /etc/cifsconfig_share.cfg. "CIFS restart". "Year! I am the master !" But I was too stupid again. Because now my CIFS Clients got the shares but they could not see any data. And I got no idea why! So I "vol rename vol0 vol1" and "vol rename vol0old vol0" And now the CIFS clients connect back to their shares on the old FC9 again. So whats wrong about my proceedings?

Snapshot question
by Miller, Michael CTR USTRANSCOM J2 07 Feb '07

07 Feb '07

I have a soon to be problem with snapshots coming up. I will be deleting a directory that has 238GB in it and I would really prefer this not to get captured by a snapshot if there is anything I can do about it. I don't want to destroy the exsisting snaps either. Does anyone know of any way to keep this out of the snap? Any thoughts on how to limit the hit?

HiThis does sound like SecureAdmin might be the source of these ills, take a look at http://now.netapp.com/Knowledgebase/solutionarea.asp?id=kb6282 and http://now.netapp.com/Knowledgebase/solutionarea.asp?id=kb6270.Basically what you would need to do is:Disable SSL by running the command:secureadmin disable sslRe-create the certificate by running the command: secureadmin setup ssland re-enable SecureAdmin by running the command: secureadmin enable sslIf you disable secureadmin before copying the vol across it may even work; I don't have a filer to hand to be able to test it.Viel Glück und Viele Grüssen!Kenneth> Date: Tue, 6 Feb 2007 23:13:31 +0100> From: bormann(a)bbtel.de> To: toasters(a)mathworks.com> Subject: moving data from trad -> flex vols> > Hello,> > we are running an FAS920 with FC9 shelfs with data and new empty DS14> shelfs.> On the FC9 we got one volume /vol/vol0 with root and data on it.> > Last week we upgraded from ONTAP 6.5.6 to 7.2.1 without problems.> > Now we want to move our data to the DS14 shelfs.

Script to automate Dev System from Production.
by Rod Newcomb 06 Feb '07

06 Feb '07

I am looking for some help. We have two MS SQL servers. One is running in production, and we are snapmirroring the data over to an offsite location. Since Snapmirrors are read only, we would like to use Flexclone to create a writeable copy of this LUN for our off-site SQL server to use. We also have SnapDrive and Snap Managager/SQL software available to us. The trick is that I would like to automate the following process: Snapmirror to our offsite location (done using SMSQL) Shut down SQL at our offsite location. (No Problem) Disconnect the LUN (Using SDCLI ?) Create a new flexclone from our Snapmirrored copy. (Lun Create ?) Reconnect to the new Flexclone LUN (????) Start up SQL Services. (No problem) I would like this process to run automatically every 24 hours. Does anyone have any scripts or suggestions on how I can do this? Rod Newcomb

RE: Vista and Netapp??
by Callaway, Michael 02 Feb '07

02 Feb '07

Can other non-visa clients access this CIFS share in the way you want your vista box to access it? Just because your user is in AD, doesn't give it permissions on the share. You need to make sure that user has access on the filer through group and user permissions as well as the shares have to be given to that user or a group that user is in. I would first make the exact same setup on an XP or 2000 box (whichever you have) and determine if it's a user setup problem or something that can be directly attributed to Vista. -- *--------------------------------------- Michael Callaway (Server Administrator) North Texas Tollway Authority http://www.ntta.org <http://www.ntta.org/> 214-461-2033 o 214-325-5523 m 972-930-2633 f ---------------------------------------- ________________________________ From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com] On Behalf Of Brent Ellis Sent: Thursday, January 11, 2007 9:09 AM To: toasters(a)mathworks.com Subject: Vista and Netapp?? I am just starting to test Vista against our netapp FAS 3020c filers. We use these machines with the CIFS license for basic file sharing. The shares have Active Directory permissions applied to them and the servers have been added to AD. In Vista, I cannot connect to the servers using an AD account. Only the accounts created on the filer itself will allow me to connect from Vista. Has anyone run into this? Any solutions?

Steve I sure hope that is not the problem. I had gone down that line of thought but I keep coming back to the snapmirror transfer rates. I don't know the details of a snapmirror transfer but I would expect to see issues there also if latency was the problem.

Perhaps you can send a large burst of data to the netapp (high bandwidth) but it takes a while for that burst to travel all the way across the network (high latency). In this situation a process on the NFS client sends a request and has to wait for the request to arrive at the netapp and then wait for the response to before sending the next request. During these wait periods, more data could be sent or received, so the network just sits idle for most of the time. If the load on the netapp is really low (which is probably the case) then I suggest testing this theory by firing up a bunch of parallel processes on the NFS client that each read and/or write a large file on the netapp. If the throughput goes up, then that probably indicates latency.
