Reallocate a Deduplicated Volume?
by Brad Smith 18 Jan '13

18 Jan '13

Looking for help/direction on reallocating deduplicated volumes. Have a FAS2040 running 7.3.6 and adding an additional DS4243 shelf with SAS drives and want to extend current aggregate by adding a new raid group created with the new disk to the aggregate. On this aggregate I have volumes that are deduplicated and have snapshots. I have read several NetApp documents that seem to conflict on running reallocate on the volumes after adding the new disks to the existing aggregate. I have read you should reallocate but not on a volume that is deduplicated. I have also read that if you use the -p switch this will be OK, reallocate start -f -p /vol/VOLUMENAME. Will I have problems if I run reallocate on my deduplicated volumes? Thanks. Brad

Snapvault between 8.0.2P4 and 8.1.1
by Steven Kreuzer 17 Jan '13

17 Jan '13

Hello- I have two filers that are both running 8.0.2P4 and they are both snap vaulting a volume from one to the other. Rebooting one of the filers requires tons and tons of coordination between several different groups and the other filer I can pretty much reboot whenever I fancy. I would like to upgrade that filer to 8.1.1 so I can take advantage of all the 64 bit migration stuff and also test out the branchcache support. The only thing I am concerned about is that I may lose the ability to snapvault between the two. I recall it was not possible to snapvault from a filer running 8.x to one running 7.x, is it possible to still snap from a filer running 8.0 to one running 8.1? Thanks

Re: wafl_cp_slovol_warning_1 with big latency spikes
by Brian Beaulieu 17 Jan '13

3rd time is the charm. I've attached my sysstat from the other night when NFS/CIFS hung up... is this what you've seen as well? During that issue, FCP was also slow.. had some MPIO failovers happening on our AIX LPARs. But, AIX handles that just fine and at least has an alternate path through the other filer. NFS isn't so lucky. I have a 3250+1TB PAM sitting on deck.. you'd think that the 3240+512GB PAM would be sufficient for what we do. While I do have SATA in use for VMWare, it's not heavy hitting VMs.. it's the dormant stuff, mostly. I'm moving a lot of it, though, to 6xDS4243x600GB-15k shelves ASAP. I'm drinking the PAM kool-aid too but do have some measurable results primarily on our PeopleSoft DB2 databases. I definitely wouldn't bet on SATA+PAM == FC/SAS performance. Brian

wafl_cp_slovol_warning_1 with big latency spikes
by Fletcher Cocquyt 16 Jan '13

16 Jan '13

resending this without the 80kb chart Yesterday morning one of the heads on our 3270 experienced large NFS latency spikes causing our VMware hosts and their VMs to log storage timeouts. This latency does not correlate to any external metrics like CPU, network, OPS etc. But in the logs do show CP events on the aggregate hosting the VMs: Jan 14 05:27:56 [n04:wafl.cp.slovol:warning]: aggregate aggr2 is holding up the CP. And the EMS log has CP events logged for the duration of the episode - what can we do to prevent these issues? <wafl_cp_toolong_warning_1 total_ms="117825" total_dbufs="32276" clean="4312" v_ino="3" v_bm="29" a_ino="0" a_bm="3428" flush="1209"/> </LR> <LR d="14Jan2013 05:19:38" n="irt-na04" t="1358169578" id="1335304168/148007" p="4" s="Ok" o="wafl_CP_proc" vf="" type="0" seq="633232" > <wafl_cp_slovol_warning_1 voltype="aggregate" volowner="" volname="aggr2" volident="" nt="35" nb="22045" clean="1346852" v_ino="0" v_bm="113" a_ino="0" a_bm="4" flush="0" rgid="2"/> Netapp support wants me to run perfstats, but the issue is not ongoing - things are idle thanks

PDU in netapp cabinet mysteriously switched off
by Steve Losen 15 Jan '13

15 Jan '13

Hi Folks, Last Sunday six shelves in a netapp cabinet each lost power to one PSU. The other PSUs still had power, so no downtime. I investigated and the PDU in the cabinet that the PSUs are plugged into was powered off, i.e., the switch was in the "off" position. I flipped the switch and everything went back to normal. The PDU is plugged into its own 240V circuit. The same thing happened to us several months ago, but I can't remember if it was the same PDU. I am very confident that when this happened, no one was anywhere near that cabinet (or even in the room). This was definitely "spontaneous". Has anyone heard of a netapp cabinet PSU switch flipping itself to "off" ? Does it behave like a breaker if there is a surge? I'm trying to remember if the "off" position is down. Could the switch be faulty and get flipped by gravity and vibration? Steve Losen scl(a)virginia.edu phone: 434-924-0640 University of Virginia ITC Unix Support

New Bundled DS4243 Shelves
by Brian Beaulieu 15 Jan '13

15 Jan '13

I received our order of a new FAS3250 along with a 7 shelves. I want to use the shelves on our FAS3240 for now. We'll be doing a head swap in the future. I got 5 of the shelves attached today and then realized they were all owned by the FAS3250 that we got. On top of that, it looks like all disks are in an aggregate. I suspect this because I forced disk ownership of drive 0 on one of the shelves and it imported aggr0 but then renamed it to aggr0(1) and put it offline. I tried the same thing with drive 0 of another shelf and that imported aggr0(2) and put it offline. So, what's the best way to handle this? disk reassign ? My fear is if I import 144 drives using 'disk assign <disk> -s <sysid>-f', I will end up with 144 aggr0(X) offline aggregates and then have to clean all of that up. Once the headswap is done, the FAS3240 along with the other 2 remaining shelves will be going to our DR site and I imagine I'll be doing a fresh install of OnTAP on there since there will be no root vol Thanks!

When is 1Tb == 1000Gb == 1000^2Mb == 1000^3Kb == 1000^4bytes ?
by Fletcher Cocquyt 13 Jan '13

13 Jan '13

This came up when I was doing some work with our new backup vendor's API, pulling out their backup numbers all reported in bytes and converting to Gb or Tb for our cacti graphs. set bytes=7696581394432 echo $bytes bytes = `echo $bytes"/1024/1024/1024/1024" | bc` Tb 7696581394432 bytes = 7 Tb But the numbers on the vendors dashboard were different. I asked vendor support and the next day they confirmed (as I suspected) they were converting using powers of 10 But what I did not know, was this was on purpose due to the disk manufacturer's convention: http://en.wikipedia.org/wiki/Hard_disk_drive#Units For someone with a computer science background this was surprising to not have uniform definitions of units across media Ram manufacturers don't do this according to the article they use (do Flash or SSD makers?) So if I have full 1Tb RAM drive and try to copy it to a 1Tb HDD, it won't fit - I'll need 9.95% more space due to the different definitions of Tb Made me wonder what the Netapp reporting tools, OpsMgr, System Manager, DFM etc do when reporting the #bytes available on a HDD as Tb do they do binary or decimal conversions? What are some other implications of the unit definition difference? thanks

CIFS Proxy
by Steven Kreuzer 11 Jan '13

11 Jan '13

Greetings- I have a remote office that is a mix of Windows and Unix clients that have to access a filer far away in our main office. For the unix folks, we have deployed a flexcache and their quality of life has greatly improved. It looks like NetApp doesn't offer any type of flexcache type solution for CIFS so I am look at other options. Are there any flexcache like solutions from a 3rd party that people have deployed and is anyone using a tcp accelerator appliance such as Riverbed to speed to access to a volume via CIFS? At this point, I am open to just about any solution :) Thanks

Where does the "125L" come fromin diskname 0c.125L72 (when using ATTO FC-to-SAS bridges)
by Filip Sneppe 10 Jan '13

10 Jan '13

Hi, This is perhaps a bit of a silly question, but a customer of ours asked this , and I am not able to provide him with a full answer. On a FAS system with ATTO FC-to-SAS bridges, a disk is identified by a name like this 0c.125L72. On a V-series system, you may encounter disks names such as "fcswitchname:17.126L31". This link: https://library.netapp.com/ecmdocs/ECMP1147535/html/GUID-6F23FBA1-07DC-4CF1… explains the 125L and 126L are device IDs, but can anyone give me a little more information on what they represent, how they are set etc. Thanks in advance, Filip

Latency reporting
by Peta Thames 04 Jan '13

04 Jan '13

Hi and happy new year to you all! My first conundrum of 2013... Anyone got any ideas on how I get the amount of time in any given time period that overall FCP read/write latency has been above a certain threshold? The threshold is already set in perf advisor and has been for some time. I have the usual free opsmanager tools to hand, plus Balance. I know there are other performance metrics I can and do look at, however for this report I have very explicitly been asked to find something that can be expressed as a percentage, and so far this is the best I can come up with (% of time in a month spent over the threshold). Any other ideas would be welcome though. Thanks, Peta

BURT 519766 panic on production 3270
by Fletcher Cocquyt 02 Jan '13

02 Jan '13

Happy 2013! One of our production 3270 heads panic'ed and rebooted 3:30 am Dec 25 - lump of coal ? The good news is, when our system panic'ed and rebooted, the failover performed as expected so we had only a 2 second timeout logged on our ESXi hosts, Oracle - no downtime. There is scarce public info on this issue and Netapp is recommending options from "do nothing - (its rare and may never happen again)" to "replace motherboards and all cards" Our 3270 clusters (we have 2 in Active:Standby mode) have been stable since we installed them in Feb 2011. We are on 8.1GA - Netapp support says the issue is independent of OnTAP version. Anyone else encountered this issue?

Aggregate Best Practices
by Ray Van Dolson 28 Dec '12

28 Dec '12

We're revisiting how we set up our aggregates and I want to see how others out there do it. Specifically, what strategies do you use for ensuring certain key applications or environments get the performance they need in a shared environment. Typcially we'll create large aggregates based on a homogeneous disk type. 15K SAS disks in one aggregate, SATA in another. In some cases when it's only a single type of disk, we'd have 60 15K disks in one aggregate and 60 in other (assigned to each controller respectively). The idea here is that more spindles gives us the most performance. However, some applications/workloads are more important than others, and some can be "bullies" impacting the important stuff. Ideally we'd try and keep our OLTP random workloads on one filer and heavy sequential workloads on another (maybe dedicated). We've also been discussing creating multiple, smaller aggregates that we then assign to specific workloads guaranteting those spindles for those workloads. Lower possible maximum performance, but better protection against "bullies"[1]. I also know ONTAP has some I/O QoS options. I'm less inclined to go that direction however. Our workloads tend to be ESX VM's using the filers as NFS datastores. We have the usual budgetary / purchasing cycle constraints, so trying to minimize pain for as long as possible until we can add resources. How do folks out there handle this? Thanks, Ray [1] Controller obviously still is shared.

question about NDMP dumps
by Scott Eno 21 Dec '12

21 Dec '12

In investigating why an NDMP dump over 10GbE isn't going as fast as it seems it should, a question arose. Does the data being dumped via netbackup to a data domain device, 1.58TB deduped down to 813GB, have to get re-hydrated as the dump proceeds? And, if so, would that impact the speed of the dump?

Moving to 64bit aggrs
by Steven Kreuzer 21 Dec '12

21 Dec '12

Greetings- On our primary filer we are running 8.0.3p2 and I have a 11TB 32bit aggregate that is close to running out of space. I would like to move this volume, along with all its snapshots to a new 64bit aggregate. >From my research, it looks like if I was running 8.1 I could either upgrade the aggr in place, or do a vol move from a 32bit 64bit aggr. In 8.0.3, do I have any options like this? I would really like to avoid using rsync to copy over a snapshot and take a snapshot on the destination, wash rinse repeat. Many Thanks

8.1.1 RLW Performance Trouble, 8.1.2 issues?
by Randy Rue 12 Dec '12

12 Dec '12

Hello All, After a few months of planning and preparation we were just about to pull the trigger on an 8.1.1 upgrade to our v3170 currently running 7.3.5.1P5 with a 3Par T800 spinning 528 SATA spindles. We've crawled through release notes and upgrade notes, used the online "upgrade advisor" tools, checked this list and engaged our NetApp SE. Tested against a simulator , killed a chicken at midnight of the full moon, etc. Then last week one of our admins found this link and asked in passing if this issue was relevant to our situation: Data Ontap 8.1 upgrade - RLW_Upgrading process and other issues https://communities.netapp.com/thread/22676 Looks like upgrading to 8.1x implements a new layer of protection called RLW (RAID protection from Lost Writes). This requires the addition of some metadata to the disk system and after upgrade a background process "rlw_update" runs for some period of time. The trouble is, this process does not "nice" itself as it's meant to when other processes are running. Worse, if it runs at the same time as other "not so nice" processes like de-dupe there can be disastrous performance issues. This problem is exacerbated if disk utilization is high, or if slower disks are used, or if a lot of misaligned traffic is running. Users in the wild have reported the rlw_update process taking several weeks and horrible performance issues during its tenure. Yike, I'm just glad we found out about this now and not Monday morning. Our filer consistently runs ~90% disk utilization, is usually running two or three de-dupe processes, is running on SATA disks, and one node does nothing but serve up NFS datastores to our VMware farm which we suspect is running mostly misaligned VMDK files. So now we've postponed the upgrade. We'll need to retest against 8.1.2 (or later). We're averse to get too eager to upgrade to 8.1.2 until it's been out a while, especially as NetApp seems to be on a roll lately, releasing new versions to address performance issues that then seem have performance issues. We're also concerned about upgrading to any new version while the system is heavily loaded (we're also in the process of deploying a new block-level storage system that will offload more than half of the current performance load on the v3170). So. This post is intended first as a heads-up to anyone in a similar situation who's about upgrade to 8.1.1. Another takeaway might be to acknowledge the value of the official NetApp Communities pages: I've usually relied on this toasters list and/or our NetApp/VAR technical staff, but will also be following the "official" user community resources from now on. And I also welcome any feedback from anyone with experience or information to offer. Anyone been in this situation? Anyone running 8.1.2 yet? Anyone have advice on upgrading a significantly busy system? Hope to hear from you, Randy Rue Seattle

CIFS share hiding qtrees within it
by Andrew Leonard 08 Dec '12

08 Dec '12

Yesterday afternoon around 2p local time, a CIFS share of a FlexVol containing multiple qtree spontaneously began hiding the qtrees within the share (filer is running 8.0.2P3 7-Mode): At the root of the share, non-qtree directories are still visible; qtrees are no longer visible. However, if a user enters the path to the qtree manually, they can access a hidden qtree and files beneath it. By "spontaneously," I mean that /etc/log/auditlog and our homegrown API-based tool confirm that there were no filer configuration changes made. The FlexVol and qtrees are all ntfs mode. The "hidden qtree" behavior has been seen on SMB connections from Windows 7, w2k3 and OS X (at least 10.8, probably other versions). We also share this FlexVol to NFS clients, although usage is light. NFS clients can see and access all qtrees as usual. There were a couple of initial reports from OS X users that they could not connect to the share at all, although I could not confirm or replicate this myself. Share permissions are basic: Name Mount Point Description ---- ----------- ----------- General /vol/general General public share everyone / Change BUILTIN\Administrators / Full Control DAYJOB\Domain Admins / Full Control If we use "Previous versions" on Windows to access the 12p snapshot yesterday, the qtrees are all visible. Using "cacls" or the "Security" tab to view permissions on both hidden and visible directories shows nothing unexpected - and no changes in permissions relative to the 12p snapshot. A "cifs terminate"/"cifs restart" requested by NetApp support did not resolve the issue; they continue to work on it, but assert that they have never seen anything like it before. I'd be grateful for any ideas anyone here might have. Thanks, Andy

File size and age distribution stats per volume on Ontap8.1?
by Kawakubo, Ken 07 Dec '12

07 Dec '12

Dear List, I am trying to get file size and age distribution stats per volume on a Ontap8.1 system. Apparently, "filestats" command was removed on Ontap8.1 as "filestats" relies on java and java was removed on 8.1. Does anybody know of any quick ways to get this kind of stats on 8.1? Regards, Ken Kawakubo Seattle

Flexcache on 7.2.6.1
by Steven Kreuzer 07 Dec '12

07 Dec '12

I have an old 2050 running 7.2.6.1 which has been decommissioned in favor of new equipment running 8.0.2P4 I would like to redeploy the 2050 at a remote office as a flexcache volume of the new filer to improve the quality of life for the folks working remotely. I don't see any reason why this would be a bad idea, but is there anything I should be aware of when putting a flexcache volume on a filer running 7.2.6.1 (I am going to put the latest 7 code release on it before it gets deployed) in front of a filer running 8.0.2p4?

CIFS clients unable to access folders/ACL's until attached session is closed
by Ray Van Dolson 05 Dec '12

05 Dec '12

Got a strange one here... Have a folder (NTFS qtree w/ oplocks on) shared out via CIFS (also NFS, but expected to be minimal NFS access but still a variable). This folder contains files used for internal software builds/compiles and so several clients can be accessing it at the same time. CIFS clients in this case are typically Mac OSX. Ocassionally (lately, a couple of times a day), CIFS clients are unable to access portions of the tree. Even from Windows we get a permission denied error and can't even view ACL's on the affected folder. To solve the problem, we look for a CIFS client holding the location open and close it out. Then the folder becomes usable again. The CIFS client only has the folder open in "Read" mode. A couple thoughts from my side: - Maybe we should disable oplocks. Shouldn't be a lot (if any) NFS access to this share, but is a variable. - Our permissions are a bit wonky here. Share level permissions are in place to restrict most access to read-only, but file level permissions are set to full for "Everyone". Perhaps this is resulting in some sort of exclusive locking happening based on the more open nature of the file system permissions even if the share level allows read only? We'll probably try the oplocks thing for starters, but looking for any insights. Oh -- this is ONTAP 8.0.2P3 in 7-mode. Thanks, Ray
