v3170 Setup
by Chris hansen 05 Jul '15

05 Jul '15

I have a old v3170 in my lab with one MK2 SATA shelve. I am trying to find documentation on setup for wiring and HA setup. I have one side working but can’t seem to get both sides working….assume I have some wiring wrong. Searching online I can’t find much out on this model. Thanks -Chris

Fixing NTFS permissions in cDOT 8.3 CIFS share
by John Stoffel 03 Jul '15

03 Jul '15

Guys, I've got a strange problem with a CIFS share on a cDOT 8.3 system. It's a small 2250 with some NFS storage for ESX and one volume with a single CIFS share. The local admin to making changes to permissions and managed to lock himself out completely. The top level share name is /MIS, and we can get into sub-folders (luckily!) but can't actually map the top level any more. I've opened a ticket, and I'm reading the man pages at: https://library.netapp.com/ecmdocs/ECMP1196891/html/GUID-3D32772D-B4E8-4497… but I'm hesitant to make changes. So here's some example info: ntap_019::*> vserver security file-directory show -vserver filestorage -path /MIS Vserver: filestorage File Path: /MIS Security Style: ntfs Effective Style: ntfs DOS Attributes: 10 DOS Attributes in Text: ----D--- Expanded Dos Attributes: - Unix User Id: 0 Unix Group Id: 0 Unix Mode Bits: 0 Unix Mode Bits in Text: --------- ACLs: NTFS Security Descriptor Control:0x9504 Owner:BUILTIN\Administrators Group:BUILTIN\Administrators DACL - ACEs ALLOW-FOO\MIT Admins-0x1f01ff-OI|IO ntap_019::*> vserver security file-directory show -vserver filestorage -path /MIS/UserDrives Vserver: filestorage File Path: /MIS/UserDrives Security Style: ntfs Effective Style: ntfs DOS Attributes: 10 DOS Attributes in Text: ----D--- Expanded Dos Attributes: - Unix User Id: 65534 Unix Group Id: 65534 Unix Mode Bits: 0 Unix Mode Bits in Text: --------- ACLs: NTFS Security Descriptor Control:0x8504 Owner:FOO\someone Group:FOO\Domain Users DACL - ACEs ALLOW-FOO\MIT Admins-0x1f01ff-OI|IO (Inherited) And since I'm a Linux/Netapp admin with limited understand of NTFS or Windows, I'm wondering what I can do to fix the permissions, or at least be able to open things up so that we can go in and fix it properly. I have tried setting up a 'vserver security trace filter create ...' but it never seemed to give me any results back. Is there any simple way I can just change the top level permissions to make them WIDE open, so they can be modified again? I even tried creating a new share, thinking that it was a share level issue, but it looks more like it's an NTFS permissions issue, which is why I'm stuck. Thanks, John

API calls to replicate a 'df'
by Edward Rolison 03 Jul '15

03 Jul '15

I'm currently fiddling with a project using the ONTAPI (perf stats monitoring sort of thing). What I'm wanting to do is reproduce the information from 'df' and 'df -s'. Doing well so far, because the api 'volume-list-info' seems to have most of the information I want. There's just one thing missing - how much of the 'snap reserve' I'm actually using. I can't seem to find it in either that, or the 'snapshot' counters. I would ideally be able to do this without having to do a per-volume calculation, because one of the things I'm hoping to do is support a lightweight proxy client that 'just' fetches source XML for processing on a server. Or is there a way I can calculate this from the size/used/available in the volume-list-info? Thanks, Ed

maxdirsize
by Rhodes, Richard L. 03 Jul '15

IBM N3220 - 2857-A22 (NetApp FAS2240-2) Data ONTAP Release 8.1.2P1 7-Mode We are trying to move a share from a EMC CX4 to a nSeries system. The method for moving is to mount both shares to a Win server and robocopy. The application using this share has a BUG - it creates little files and NEVER deletes them. There is now almost 10m files in the share, almost all of them in one directory. This bug won't be resolved anytime soon. ==> PROBLEM The robocopy runs, then fails with out of space condition. The filer gets the following these messages - all the same - all for the same directory "Resubmitted". ___ Thu 06 11 17:28:28 EDT [isnapr0664a:wafl.dir.size.max:warning]: Directory /vol/v_prdieeapp_cifs/q_prdieeapp_cifs/XXXXData/Data/HVRI/Resubmitted/ reached the maxdirsize limit. Reduce the number of files or use the vol options command to increase this limit. ==> Comments/Questions So we've hit the maxdirsize on something, but on what? The Win admin doing the robocopy ran TreeSize Professional on both shares, and it looks like the copy is almost complete. The REALLY WEIRD THING is that the dir "WorkBIn" with +8m files did NOT get any errors. But the dir "Resubmitted" with +470k files DOES get the errors. Q) Why would we hit maxdirsize on a dir with +460k files, but not hit maxdirsize on a dir with +8m files? Q) Is maxdirsize for an entire dir structure, or, for an individual dir? I have a case open with IBM support, but not getting very far. ==> maxdirsize ssh -q xxxxxxxx options wafl.maxdirsize wafl.maxdirsize 45875 ==> vol size Size = 1tb, used = 564gb, avail = 484gb Thin, autogrow = 5g ssh -q xxxxxxxx df /vol/v_prdieeapp_cifs/ Filesystem kbytes used avail capacity Mounted on /vol/v_prdieeapp_cifs/ 1048576000 564393044 484182956 54% /vol/v_prdieeapp_cifs/ /vol/v_prdieeapp_cifs/.snapshot 0 0 0 ---% /vol/v_prdieeapp_cifs/.snapshot => inodes Used = +10m, Free = +21m ssh -q xxxxxxxx df -i /vol/v_prdieeapp_cifs/ Filesystem iused ifree %iused Mounted on /vol/v_prdieeapp_cifs/ 10056313 21073268 32% /vol/v_prdieeapp_cifs/ => vol options ssh -q xxxxxxxx vol options /vol/v_prdieeapp_cifs nosnap=on, nosnapdir=off, minra=off, no_atime_update=off, nvfail=off, ignore_inconsistent=off, snapmirrored=off, create_ucode=on, convert_ucode=on, maxdirsize=45875, schedsnapname=ordinal, fs_size_fixed=off, guarantee=none, svo_enable=off, svo_checksum=off, svo_allow_rman=off, svo_reject_errors=off, no_i2p=off, fractional_reserve=0, extent=off, try_first=volume_grow, read_realloc=off, snapshot_clone_dependency=off, dlog_hole_reserve=off, nbu_archival_snap=off ==> TreeSize info of SOURCE and TARGET shares SOURCE share ------------ Full Path Size Allocated Files Folders Y:\ 513,366.5 MB 564,771.9 MB 10,077,444.00 713 Y:\XXXXData 513,366.2 MB 564,771.7 MB 10,077,437.00 710 Y:\XXXXData\Data 513,181.4 MB 564,585.9 MB 10,077,161.00 609 Y:\XXXXData\Data\HVRI 345,036.1 MB 394,556.1 MB 9,597,937.00 476 Y:\XXXXData\Data\HVRI\Readings 312,822.8 MB 312,898.3 MB 18,255.00 0 Y:\XXXXData\Data\HVRI\WorkBin 22,386.3 MB 68,378.2 MB 8,768,414.00 473 Y:\XXXXData\Data\HVRI\Resubmitted 9,827.0 MB 13,279.6 MB 811,268.00 0 Y:\XXXXData\Data\Import 167,672.7 MB 169,541.3 MB 475,794.00 102 Y:\XXXXData\Data\Export 470.3 MB 486.1 MB 3,420.00 27 Y:\XXXXData\Data\XMLExamples 2.3 MB 2.4 MB 10.00 0 Y:\XXXXData\CRFFiles 144.0 MB 144.9 MB 255.00 83 Y:\XXXXData\IEE Installs 29.4 MB 29.5 MB 20.00 12 Y:\XXXXData\RODSData 11.4 MB 11.4 MB 1.00 2 Y:\.etc 0.3 MB .3 MB 7.00 0 Y:\lost+found 0.0 MB .0 MB 0.00 0 TARGET share ------------ Full Path Size Allocated Files Folders Z:\ 490,573.6 MB 518,678.1 MB 9,776,433.00 714 Z:\XXXXData 490,573.3 MB 518,677.8 MB 9,776,426.00 710 Z:\XXXXData\Data 490,388.6 MB 518,492.5 MB 9,776,150.00 609 Z:\XXXXData\Data\HVRI 322,961.8 MB 350,056.7 MB 9,299,556.00 476 Z:\XXXXData\Data\HVRI\Readings 294,757.3 MB 294,792.3 MB 17,375.00 0 Z:\XXXXData\Data\HVRI\WorkBin 22,621.6 MB 48,775.0 MB 8,823,422.00 473 Z:\XXXXData\Data\HVRI\Resubmitted 5,582.8 MB 6,489.4 MB 458,759.00 0 Z:\XXXXData\Data\Import 166,956.4 MB 167,957.6 MB 473,182.00 102 Z:\XXXXData\Data\Export 468.0 MB 475.8 MB 3,402.00 27 Z:\XXXXData\Data\XMLExamples 2.3 MB 2.4 MB 10.00 0 Z:\XXXXData\CRFFiles 144.0 MB 144.5 MB 255.00 83 Z:\XXXXData\IEE Installs 29.4 MB 29.4 MB 20.00 12 Z:\XXXXData\RODSData 11.4 MB 11.4 MB 1.00 2 Z:\.etc 0.3 MB 0.3 MB 7.00 0 Z:\~snapshot 0.0 MB 0.0 MB 0.00 0 Z:\lost+found 0.0 MB 0.0 MB 0.00 0 ----------------------------------------- The information contained in this message is intended only for the personal and confidential use of the recipient(s) named above.

Hi All, Found that $subj is actually available (just by probing URLs), but NetApp didn't publish references to that anywhere. Is it "production ready"? What do you think guys? Cheers,

CDOT failover groups in 8.2.1P6
by Mark Flint 02 Jul '15

Does anyone know if you can re-order the entries within a failover group? My understanding of this is that it’s an automagically created list, but I’d be real happy to find out I’m misunderstanding the docs :) ~Mark mark.flint(a)sanger.ac.uk

FAS2xxx Upgrade - Flash Cache Performance Estimation?
by Stephen Stocke 30 Jun '15

30 Jun '15

Greetings We're looking to upgrade two sites which consist of a FAS2020 (7.3.7) and FAS2240-2 (8.1.4-7m) at each site. The 2240-2 systems have a FlashPool accelerated aggregate and the customer is happy with the performance. The new filers will be either a FAS2552 with additional shelves or we may ditch the entry toasters and go with a FAS8020 system and shelves at each site. If we go with the 2552 we'll keep using FlashPool. If we go with the 8020 we have the option of going FlashCache. We'd like to evaluate the potential performance improvements of using FlashCache on the 8020 in order to help with the purchasing decision. However, reading TR-3801 it looks like the FAS2000 and 2200 platforms don't support Predictive Cache Statistics (PCS). This is confirmed by trying to enable PCS: toaster> options flexscale.enable on FlexScale PCS is not active and cannot be enabled. Are there any other tools which can help us estimate the performance benefits of FlashCache? Or perhaps some key metrics we can collect and analyse?

Hello list, I’m trying to understand if it’s possible to get info similar to the 7-mode command nfsstat -l I apparently need to collect statistics with the statistics start -object nfs* -vserver svm But would like to be able to pinpoint the top 10 NFS hosts, could someone let me know how if they’ve worked it out, or commiserate if not :( ~Mark

cluster mode 8.2.3 / 8.3 dynamic home directory change
by Tomlinson, Thomas 30 Jun '15

30 Jun '15

Hi Toasters, I just stumbled upon a change in 8.2.3/8.3 with respect to the dynamic home shares and curious to get other folks views on it. Currently we make extensive use of the traditional static 7mode home directory share, cifs.homedir (\\filername\cifs.homedir<file:///\\filername\cifs.homedir>). This is further referenced behind DFS as a single link name with multiple targets. It works great, allows for all users to have a static username defined in AD, allows migration of filers without massive user updates, DR, etc. So life is good, or as good as it can be managing windows home directories. We're now slowly staring to lifecycle 7mode clusters to cmode, which has had a few hiccups, but I expected that . Prior to 8.2.3, you can replicate 7mode home directory functionality perfectly, even making up whatever static name you want. Fast forward to just recently when I was configuring a small cluster at a remote location. 8.2.3, sure slap that on. Configure the dynamic home directories, sure,errr.... no. A seemingly innocent entry in the release notes for 8.2.3 states that static names are no longer acceptable. A previously configured static share is brought forward and continues to function but you can no longer create new ones. Any new dynamic home share has to have the username in it (%w or %u). Needless to say this is a major change to our environment. Automation changes, massive AD updates (close to a nightmare with our IT organization) and a complete invalidation of our DFS namespace structure for home directories. Is anyone else similarly affected by this? I'm struggling to understand what twisted logic guided this coding decision.
