1gb sfp support in fas2500
by Mike Gossett 09 Dec '15

09 Dec '15

I was reading the tech specs on the fas2552/4 platforms and there is verbiage indicating that with 8.3.1 and onward, there is support for 1gb sfp modules in the uta2 ports. I have deployed many of these units in the past 18 months and have always forced 10gb switching to support it, even though 4x1g may have been adequate in some circumstances. My NetApp sales team seems to be unfamiliar with this and is researching. Can anyone shed some light on this for me? Are there 1g copper modules or only 1g fiber sfp? Has anyone quoted / sold / deployed these yet? Any caveats? Thanks Mike Sent from my mobile phone

Hey, does anyone have the download link for SP firmware 2.3.2 at hand? The website is still showing 2.3.1 as the latest and greatest and we got two FAS2552 delivered recently and one of them came with 2.3.2 already, so I'd like to update the second one tot hat release too :) ::*> sp show IP Firmware Node Type Status Configured Version IP Address ------------- ---- ----------- ------------ --------- ------------------------- nodeA SP online true 2.3.2 10.100.55.112 nodeB SP online true 2.3.2 10.100.55.111 Thanks, Alexander Griesser Head of Systems Operations ANEXIA Internetdienstleistungs GmbH E-Mail: AGriesser(a)anexia-it.com<mailto:AGriesser@anexia-it.com> Web: http://www.anexia-it.com<http://www.anexia-it.com/> Anschrift Hauptsitz Klagenfurt: Feldkirchnerstraße 140, 9020 Klagenfurt Geschäftsführer: Alexander Windbichler Firmenbuch: FN 289918a | Gerichtsstand: Klagenfurt | UID-Nummer: AT U63216601

FAS8040 getting crushed by Solr replication
by Philip Gardner, Jr. 04 Dec '15

04 Dec '15

Hi all - I have an 8040 with 88 x 900G 10k disks, all assigned to a single aggregate on one of the controllers. There are a few volumes on here, all vSphere NFS datastores. This aggregate also has a slice of flash pool assigned to it, currently about 900GB usable. We recently deployed some CentOS 6 VMs on these datastores that are running Solr, which is an applciation that is used for distributed indexing. The replication is done in typical a master/slave relationship. My understanding of Solr's replication is that it is done periodically where the slaves download any new index files that exist on the master but not on the slaves, into a temp location, and then the slaves replace their existing index files with the new index files from the master. So it appears to be a mostly sequential write process. During the replication events, we are seeing the controller hosting this particular datastore basically getting crushed and issuing B and b CPs. Here is some output of sysstat during one of the replication events: CPU Total Net kB/s Disk kB/s Tape kB/s Cache Cache CP CP Disk ops/s in out read write read write age hit time ty util 7% 854 60795 38643 14108 107216 0 0 20 96% 100% : 9% 7% 991 61950 41930 6542 89350 0 0 20 95% 100% : 9% 4% 977 62900 38820 1244 2932 0 0 20 93% 9% : 1% 4% 811 52853 35658 76 12 0 0 20 96% 0% - 1% 5% 961 67428 43600 60 12 0 0 20 97% 0% - 1% 4% 875 57204 41222 66 4 0 0 20 97% 0% - 1% 5% 1211 78933 59481 110 12 0 0 20 97% 0% - 1% 16% 1024 55549 31785 33306 84626 0 0 20 97% 89% T 14% 7% 1164 56356 36122 14830 102808 0 0 20 96% 100% : 8% 49% 13991 909816 56134 3926 62136 0 0 24 82% 100% B 7% 78% 13154 842333 55302 53011 868408 0 0 24 83% 100% : 51% 83% 12758 818914 59706 44897 742156 0 0 23 89% 97% F 45% 84% 11997 765669 53760 64084 958309 0 0 26 89% 100% B 59% 80% 11823 725972 46004 73227 867704 0 0 26 88% 100% B 51% 83% 15125 957531 46144 42439 614295 0 0 23 87% 100% B 36% 74% 9584 612985 42404 67147 839408 0 0 24 93% 100% B 48% 78% 11367 751672 64071 49881 770340 0 0 24 88% 100% B 46% 79% 12468 822736 53757 38995 595721 0 0 24 87% 100% # 34% 56% 6315 396022 48623 42597 601630 0 0 24 94% 100% B 35% 67% 7923 554797 56459 26309 715759 0 0 24 87% 100% # 43% 69% 13719 879990 37401 41532 333768 0 0 22 87% 100% B 22% 45% 24 52946 42826 33186 736345 0 0 22 98% 100% # 41% 72% 13909 888007 46266 29109 485422 0 0 22 87% 100% B 28% 59% 8036 523206 53199 41719 646767 0 0 22 90% 100% B 37% 68% 7336 505544 63590 46602 870744 0 0 22 91% 100% B 49% 71% 12673 809175 29070 21208 556669 0 0 6 89% 100% # 38% 70% 12097 726574 49381 36251 588939 0 0 24 90% 100% B 35% And here is some iostat output from one of the Solr slaves during the same timeframe: 12/03/2015 06:48:36 PM avg-cpu: %user %nice %system %iowait %steal %idle 7.54 0.00 7.42 44.12 0.00 40.92 Device: rrqm/s wrqm/s r/s w/s rMB/s wMB/s avgrq-sz avgqu-sz await svctm %util sda 0.00 4.50 0.00 0.00 0.00 0.00 0.00 5.46 0.00 0.00 62.65 sdb 0.00 26670.00 0.00 190.50 0.00 95.25 1024.00 162.75 214.87 5.25 100.00 dm-0 0.00 0.00 1.00 11.50 0.00 0.04 8.00 5.59 0.00 50.12 62.65 dm-1 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 dm-2 0.00 0.00 0.00 3.00 0.00 0.01 8.00 2.44 0.00 135.33 40.60 dm-3 0.00 0.00 0.00 26880.00 0.00 105.00 8.00 20828.90 194.77 0.04 100.00 12/03/2015 06:48:38 PM avg-cpu: %user %nice %system %iowait %steal %idle 9.23 0.00 16.03 24.23 0.00 50.51 Device: rrqm/s wrqm/s r/s w/s rMB/s wMB/s avgrq-sz avgqu-sz await svctm %util sda 0.00 177.00 1.00 19.50 0.00 0.79 78.83 7.91 651.90 16.59 34.00 sdb 0.00 73729.00 0.00 599.50 0.00 299.52 1023.23 142.51 389.81 1.67 100.00 dm-0 0.00 0.00 0.00 0.00 0.00 0.00 0.00 4.56 0.00 0.00 27.55 dm-1 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 dm-2 0.00 0.00 0.00 186.50 0.00 0.73 8.00 87.75 483.59 1.82 34.00 dm-3 0.00 0.00 0.00 74310.00 0.00 290.27 8.00 18224.54 402.32 0.01 100.00 12/03/2015 06:48:40 PM avg-cpu: %user %nice %system %iowait %steal %idle 9.27 0.00 10.04 22.91 0.00 57.79 Device: rrqm/s wrqm/s r/s w/s rMB/s wMB/s avgrq-sz avgqu-sz await svctm %util sda 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 sdb 0.00 24955.50 0.00 202.00 0.00 101.00 1024.00 142.07 866.56 4.95 100.05 dm-0 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 dm-1 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 dm-2 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 dm-3 0.00 0.00 0.00 25151.50 0.00 98.25 8.00 18181.29 890.67 0.04 100.05 12/03/2015 06:48:42 PM avg-cpu: %user %nice %system %iowait %steal %idle 9.09 0.00 12.08 21.95 0.00 56.88 Device: rrqm/s wrqm/s r/s w/s rMB/s wMB/s avgrq-sz avgqu-sz await svctm %util sda 0.00 2.50 0.00 1.50 0.00 0.01 18.67 0.46 36.33 295.33 44.30 sdb 0.00 59880.50 0.00 461.50 0.00 230.75 1024.00 144.82 173.12 2.17 99.95 dm-0 0.00 0.00 0.00 1.00 0.00 0.00 8.00 0.81 0.00 407.50 40.75 dm-1 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 dm-2 0.00 0.00 0.00 3.50 0.00 0.01 8.00 0.13 37.29 10.14 3.55 dm-3 0.00 0.00 0.00 60352.50 0.00 235.75 8.00 18538.70 169.30 0.02 100.00 As you can see, we are getting some decent throughput, but it causes the latency to spike on the filer. I have heard that the avgrq-sz in iostat is related to the block size, can anyone verify that? Is a 1MB block size too much for the filer? I am still researching if there is a way to modify this in Solr, but I haven't come up with much yet. Note, the old Solr slaves were made up of physcal DL360p's with only a local 2-disk 10k RAID1. The new slaves and relay-master are currently all connected with 10Gb, which removed the network 1Gb bottleneck for the replication, which could be uncorking the bottle so-to-speak. I'm still at a loss why this is hurting the filer so much though. Any ideas? -- GPG keyID: 0xFECC890C Phil Gardner

Re: Shutting down a controller pair in a 4-node cluster.

Yes manually moving epsilon is feasible in a planned downtime scenario.

That would only happen for a new/fresh slave with no existing index. The index is split into many files, and only the new ones that the master creates are pulled down by the slaves and written to disk. We are talking about 1-2GB for an update, but only if there are updates to the master.

I agree there are a few different ways to do it, but the snapmirror option seems like a good one. I also agree that its ineffecient to have the same copy of data getting written numerous times. These are really write heavy at the moment because they are not in production yet. We just recently got these new VMs set up and going, and I was just watching performance take a hit across this controller and wanted to investigate. The index does need to be updated relatively frequently. We use this particular index to store vehicle/inventory data for the frontend web site to query, so when a client makes changes on the backend, they want the changes to take affect relatively quickly; otherwise its a "bad experience" :) > What's the load on the Netapp when no nodes are writing at all?

Shutting down a controller pair in a 4-node cluster.
by Peter Choi 03 Dec '15

03 Dec '15

Hi, Please consider the following scenario, as we are conducting testing. I've done my research and received varying information from support , so I thought to get this audience's take on this. Basically we have a flexpod. - 2 cabinets; - Each cabinet consists of: CN1610, Nexus, FI, 2 x FAS8020 (cDOT 8.3.1P1), UCS blades; - Controllers are joined together in a 4-node cluster configuration; - Cabled in such a manner that we have controller HBA and switch port redundancy. If we were to shutdown a controller pair (2 nodes that are HA partners to each other), effectively shutting down 1 of the 2 cabinets. - Will the data on the disks attached to the other two controller nodes (the surviving HA pair) still be served and accessible? - What happens if epsilon resides on one of the nodes that are shut down. Will it be automatically shifted to a surviving member in the cluster? Thanks.

Hi, i have trouble with NFS on a Volumen with quota on 8.1.4P4 7-Mode. Diskquota not work correct. /etc/quota testuser user@/vol/vol_test 1M When testuser ist copy files 2x 512k (as sample) and will then copy one more file, quota works. The new file is 0k. BUT when testuser copy a 5MB single file (volume is empty), ontap give me a error: wafl.quota.user.exceeded:notice: uid 1004: disk quota on volume vol_test. What is the trick???? Uwe

NETAPP TOASTERS FACEBOOK GROUP HAS BEEN CREATED

Hi everybody, don't you think that time for mail newsgroup have passed? I think so. https://www.facebook.com/groups/netapptoasters/ I've just created a new group on Facebook and named it "NetApp Toasters". I've also mutuated from the LinkedIn logo I've designed years ago a new one. And I please NetApp to let me use their own as header. I know that this could be another YAST where s stands for support :) ... but considering that NetApp mailing list is active since years maybe this group could be. Many advantages can be useful on using a FB group to share infos and comments and, moreover, to enclose same discussions in just one thread. I'm alone with a few guys managing a group that I hope will grow on a daily base, so please be patient if your admission request could take one hour such one day. Of course we all are professionals and any kind of content unpolite or inappropriate will be removed by the incontestable judgement of administrators. Thank you in advance if you'll appreciate it. My best regards, PS) netapptoasters(a)groups.facebook.com<mailto:netapptoasters@groups.facebook.com> mail sent to this address will be addressed as post...but not sure about this Dott.

On the other hands, if not with a free and quite easy to setup FB page, WHO should take the weight to create some “forum” page that could be better that a mailing list? In all these years I’ve not seen a forum page and, after all, NetApp community pages do their job well. Until now FC page has been joined by roughly 40 members, some of them from NetApp too. We’ll see it. In the main time everybody is free to open new threads wherever he/she wants. Regards. Da: toasters-bounces(a)teaparty.net<mailto:toasters-bounces@teaparty.net> [mailto:toasters-bounces@teaparty.net] Per conto di Milazzo Giacomo Inviato: martedì 24 novembre 2015 01:10 A: Toasters <toasters(a)teaparty.net<mailto:toasters@teaparty.net>> Oggetto: NETAPP TOASTERS FACEBOOK GROUP HAS BEEN CREATED Hi everybody, don’t you think that time for mail newsgroup have passed? I think so. https://www.facebook.com/groups/netapptoasters/ I’ve just created a new group on Facebook and named it “NetApp Toasters”. I’ve also mutuated from the LinkedIn logo I’ve designed years ago a new one. And I please NetApp to let me use their own as header. I know that this could be another YAST where s stands for support ☺ … but considering that NetApp mailing list is active since years maybe this group could be. Many advantages can be useful on using a FB group to share infos and comments and, moreover, to enclose same discussions in just one thread. I’m alone with a few guys managing a group that I hope will grow on a daily base, so please be patient if your admission request could take one hour such one day. Of course we all are professionals and any kind of content unpolite or inappropriate will be removed by the incontestable judgement of administrators. Thank you in advance if you’ll appreciate it. My best regards, PS) netapptoasters(a)groups.facebook.com<mailto:netapptoasters@groups.facebook.com> mail sent to this address will be addressed as post…but not sure about this Dott.
