CIFS Scanner
by Jordan Slingerland 23 Oct '13

23 Oct '13

Does anyone know of a good tool that would scan a cifs share for meta data and possibly put the information in a database that can be queried for Creator Owner Information. For example, the netapp "quota report" command shows a user owns 100GB and 5000 files. I would like to give said user a list of the 5000 files and their sizes. Alternatively, a less sophisticated too that accomplishes the same result that is better than a power shell script that could scan for this information for single user or as needed. In the past I have gathered this information to a text file with a power shell script and it was very messy and certainly less then optimal. --JMS For the fourth consecutive year, Independent Health is the highest ranked health insurance plan in the New York/New Jersey region by J.D.

Deswizzling and Reallocate
by Martin 23 Oct '13

23 Oct '13

I've recently destroyed one aggregate and merged the spared disks it into another aggregate on the same Filer. I now need to snapmirror the volumes out of this aggregate into another on another Filer (musical volumes!). I didn't run a volume reallocation on the volumes after I added the disks from the recently destroyed aggregate as I'm going to be snapmirroring the data out of it. I'm not clear on whether I will need to run a volume level reallocate on the volumes once they are in the new aggregate? Will the deswizzle post snapmirror on the destination aggregate optimise the layout on the aggregate? I did a Google for "reallocate deswizzle" and looked on the NOW site but didn't find many hits and none were relevant. I can run a reallocate measure once the volumes are on the new Filer and aggregate but wonder how the volume reallocate and deswizzling are related. -- View this message in context: http://network-appliance-toasters.10978.n7.nabble.com/Deswizzling-and-Reall… Sent from the Network Appliance - Toasters mailing list archive at Nabble.com.

unexplained read operation

Hello toasters I encounter rather strange situation I have a system FAS2040 with 1 aggr of 23x450g raid group ontap version 8.1.3p2 Every write operation being generated on this aggregate automatically caused a read operation When I try to create 100% sequential write operation using tools such as sio_ntap or filersio Instead of the expected 150Mb throughput I get 100MB write and 50MB read On another FAS2040 system using the same commands I get 100% write and no reads As you can see filersio asyncio_active 0 -r 0 64k 0 15g 60 1 /vol/test/testfile CPU NFS CIFS HTTP Total Net kB/s Disk kB/s Tape kB/s Cache Cache CP CP Disk OTHER FCP iSCSI FCP kB/s iSCSI kB/s 93% 0 0 0 5 26 1 24242 118671 0 0 0s 99% 72% Fn 43% 0 0 5 0 0 24 0 90% 0 0 0 4 4 1 40959 102501 0 0 19 100% 89% Fn 43% 1 0 3 0 0 2 0 86% 0 0 0 3 3 1 23126 125022 0 0 0s 99% 69% : 59% 0 0 3 0 0 2 0 93% 0 0 0 7 1 1 28200 135740 0 0 0s 99% 97% Ff 48% 7 0 0 0 0 0 0 92% 0 0 0 6 15 1 48764 115324 0 0 0s 99% 91% Ff 52% 0 0 6 0 0 14 0 90% 0 0 0 6 16 1 36148 156492 0 0 0s 99% 83% Ff 56% 0 0 6 0 0 14 0 95% 0 0 0 0 4 4 32784 114555 0 0 0s 99% 77% Fs 48% 0 0 0 0 0 0 0 92% 0 0 0 18 90 12 34931 104059 0 0 0s 99% 88% Fn 42% 0 0 18 0 0 79 0 88% 0 0 0 8 3 1 20463 124800 0 0 0s 100% 83% Fn 45% 5 0 3 0 0 2 0 89% 0 0 0 2 2 1 34050 112166 0 0 0s 99% 87% Fn 44% 0 0 2 0 0 1 0 92% 0 0 0 3 7 1 33025 112816 0 0 0s 99% 88% Fn 46% 0 0 3 0 0 5 0 91% 0 0 0 3 3 1 30929 130833 0 0 0s 100% 73% : 50% 0 0 3 0 0 2 0 92% 0 0 0 7 24 2 36484 134260 0 0 0s 100% 98% Ff 50% 0 0 7 0 0 22 0 86% 0 0 0 6 1 1 38608 125140 0 0 0s 99% 90% Ff 44% 5 0 1 0 0 1 0 93% 0 0 0 4 3 1 28748 104544 0 0 0s 100% 75% Ff 43% 0 0 4 0 0 2 0 87% 0 0 0 5 18 1 28128 158608 0 0 0s 100% 90% Fs 55% 0 0 5 0 0 17 0 93% 0 0 0 2 3 34 33115 104980 0 0 0s 99% 85% Fn 41% 0 0 2 0 0 1 32 84% 0 0 0 5 28 7 37185 109425 0 0 0s 100% 78% Fn 48% 0 0 5 0 0 21 0 91% 0 0 0 9 3 1 30224 118322 0 0 0s 99% 97% Fn 47% 7 0 2 0 0 1 0 89% 0 0 0 2 3 4 27649 118335 0 0 0s 99% 88% : 45% 0 0 2 0 0 1 0 CPU NFS CIFS HTTP Total Net kB/s Disk kB/s Tape kB/s Cache Cache CP CP Disk OTHER FCP iSCSI FCP kB/s iSCSI kB/s in out read write read write age hit time ty util in out in out 88% 0 0 0 14 57 39 43284 133480 0 0 0s 100% 98% Ff 50% 0 0 14 0 0 52 0 92% 0 0 0 2 6 16 47936 109432 0 0 0s 99% 86% Ff 46% 0 0 2 0 0 1 0 88% 0 0 0 23 86 3 45340 141014 0 0 0s 99% 73% Ff 55% 3 0 20 0 0 82 0 92% 0 0 0 10 5 4 21787 123980 0 0 0s 99% 80% Fn 44% 7 0 3 0 0 1 0 95% 0 0 0 2 4 3 34751 98158 0 0 0s 99% 82% Fn 44% 0 0 2 0 0 1 0 91% 0 0 0 1 3 1 35022 118549 0 0 0s 100% 60% Fn 48% 0 0 1 0 0 0 0 92% 0 0 0 87 3 1 25455 123066 0 0 0s 100% 80% Fn 47% 84 0 3 0 0 1 0 83% 0 0 0 8 32 2 36956 121303 0 0 0s 100% 88% : 46% 0 0 8 0 0 30 0 85% 0 0 0 5 2 1 62064 140088 0 0 0s 100% 92% Ff 59% 5 0 0 0 0 0 0 95% 0 0 0 3 3 1 39352 117364 0 0 0s 99% 71% Ff 48% 0 0 3 0 0 2 0 94% 0 0 0 3 3 1 42008 136943 0 0 0s 99% 94% Fs 53% 0 0 3 0 0 2 0 92% 0 0 0 0 2 7 26147 111286 0 0 0s 99% 58% Fn 44% 0 0 0 0 0 0 0 90% 0 0 0 3 3 1 29567 110665 0 0 20 99% 87% Fn 44% 0 0 3 0 0 1 0 90% 0 0 0 9 4 1 40031 111273 0 0 16 99% 86% Fn 43% 5 0 4 0 0 2 0 84% 0 0 0 0 1 1 36760 105709 0 0 0s 100% 84% Fn 43% 0 0 0 0 0 0 0 92% 0 0 0 3 3 1 31033 137891 0 0 0s 100% 99% : 53% 0 0 3 0 0 2 0 83% 0 0 0 4 6 1 32991 140148 0 0 0s 100% 89% F 51% 0 0 4 0 0 5 0 Any thoughts why this could happens ?

Slow copy of a directory full of files via an NFS client across a WAN
by Arnold de Leon 21 Oct '13

21 Oct '13

I have an NFS client (CentOS 5) that is mounting a volume from filer across a WAN with about 20ms of latency (40 ms round trip). We have an application that makes a "backup" copy of a directory of data before modifying it. The directory can contain a lot tiny of files (for example 600 files, taking up less than 12MB). I'm using NFS V3 over TCP (also tried V3 over UDP). The NFS copy (using cp -a) is glacial. Looking at the WireShark packet captures shows the client and the server in a deadly lock step request/reply situation (typically GETATTR and SETATTR). As far as I can tell the client/server are not allowing any windowing/pipelining of requests. Is there a setting I am missing to enable more outstanding requests (on the client or the server)? All the searches I've done for tuning seem to be about fixing issues for large bulk transfers. Is the NFS protocol inherently limited in this way. I expected this kind of behavior in SMB 1 but not with NFS. Thanks. arnold

AW: Dedup killing performance (again)
by Alexander Griesser 18 Oct '13

18 Oct '13

Yah, just found it while googling I guess, must be bug id #657692 :-/ Anyhow, I'm now stuck with this: > sis status Path State Status Progress /vol/CIFS_SHARES Enabled Active Fingerprint is being recovered from aggregate (6% complete) It's doing that since quite some time now, although it now actually jumped from 0% to 6%, so it at least is still alive. This bug is first fixed in 8.1.2P4 as it seems, so I might need to upgrade ASAP; for now, I'll check if it at least finishes this process now, my volume is filling up quickly, but there's still some aggregate space left so I'll just increase the volume size before it goes full. I'll go above the magic 80% fill of an aggregate then, but better that then having the volume go full. I'll see how it goes and if it troubles me too much, I hope there is a way to abort sis in that state.

Aftermarket Hardware Support?
by Randy Rue 17 Oct '13

17 Oct '13

Hello All, This is not a NetApp question but a general storage question. We have an older system with two years left in it maximum. Its support contract is coming up. We're considering going with Sherlock Services for hardware support. There's potentially a savings over the next two years that significant enough to warrant the risk. Anyone gone this route? Anyone familiar with this provider? Hope to hear from you, Randy

Cluster mode root volume recovery
by Mike Thompson 17 Oct '13

17 Oct '13

Hey all, I've got a 8.0.2 c-mode cluster that recently had a single node joined to it, and a few empty aggregates created on it. We had a extended power outtage that required a lot of gear in the data center to get shut down, and since this node in the cluster didn't have any live data or VIFs on it, it got shut down. A few days later, and we are now powering it up, but get this upon login: "The contents of the root volume may have changed and the local management databases may be out of sync with the replicated databases due to corruption of NVLOG data during takeover. This node is not fully operational. Contact support personnel for the root volume recovery procedures." The node comes up fine, can see all it's aggregates, and the other nodes in the cluster can see it via the cluster network, but the node is indeed not fully functional and part of the cluster again. It's aggregates and other info are not visible from the other nodes in the cluster. Did a wafl_check of the root aggr and vol0 and that came back clean. I seem to recall having been through this before in the past, but can't find anything in my notes. This particular cluster is not under support, due to some genius decisions by management, so I'm on my own with this. There are a few empty aggregates on this node, no volumes other than the root vol. Maybe I can force unjoin it from the cluster and rebuild it? Would rather not try to do that. If there is a way to sync up the dbs on the rootvol so it will come back into the cluster, that would be ideal. Any ideas?

Dear toasters, Did anyone seen any script that provides an oversubscription rate for a volume. Something like 1. Check for thin lun size allocated size 2. Compare that to "Occupied" size 3. Compare that to volume size And give a oversubscription rate Thanks in advance

Options reduce support renewal
by Fletcher Cocquyt 10 Oct '13

10 Oct '13

We have two 3270 clusters (active/standby) coming off 3 yr warranty support (10 trays of DS4243 + 5 trays of MK14 each) Our software ELA is also expiring - resulting in the Netapp support renewal quote being over 2 times last year's total (and budget) - they want ~$160K I'm looking for advice on support options. I've already got a quote from Zeriva for the HW support (we just need the parts, we can handle the replacement ourselves) What other creative ideas might help lower the support renewal? thanks, Fletcher
