Re: Another SSD question

I couldn't find anything about CIFS and Flash Pool not working together- could you send me a link? Flash Pool is at the aggregate level and shouldn't care what kind of data is in the volumes.

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

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.

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?

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.

check Global Status of a CDOT cluster using SNMP?
by Rue, Randy 29 Jun '15

29 Jun '15

Hello All, We're rolling out a pair of CDOT clusters and setting up Nagios monitoring. On our pre-CDOT clusters we check the global health of the filers using SNMP and the miscGlobalStatusMessage OID. It returns along the lines of: NETAPP-MIB::miscGlobalStatusMessage.0 = STRING: The system's global status is normal. In 8.3, even though the MIB that NetApp publishes for CDOT includes this OID, an SNMP query returns: NETAPP-MIB::miscGlobalStatusMessage = No Such Object available on this agent at this OID Anybody got any guidance? And if we're out of luck via SNMP, any ideas for an equivalent shell command I can pass via SSH? Hope to hear from you, Randy in Seattle

RE: OnCommand Performance Manager events
by Weihs, Yossi 29 Jun '15

29 Jun '15

Hello list, First post here … my role w/NTAP in the last three years has been with the OnCommand Performance Manager (OPM) program. For your first question – OPM 1.0 had many limitations, OPM 1.1 is the GA version and has many improvements in the troubleshooting analysis page. I can help you figure out 1.0 but we’ve fixed many of the confusing issues in it with the 1.1 release. We also have OPM 2.0 in the works coming out within weeks. I suggest you switch to 2.0 once it ships. It’s a much improved product. OPM 2.0 calculates an Aggregate and Node utilization metric, shows it front and center in the dashboard and allows you to set alert thresholds. All metrics in OPM 2.0 are hyperlinked with an explorer interface. As for figuring out what is pushing an aggregate, again there are improvements in 1.1 to help with that and 2.0 is MUCH BETTER (and yes I know I’m speaking loudly). All the best, Joseph "Yossi" Weihs Sr. Manager, Product Management Manageability Products Group NetApp “Simplicity is complexity resolved” - Constantin Brâncuși<http://en.wikipedia.org/wiki/Constantin_Br%C3%A2ncu%C8%99i> From: toasters-bounces(a)teaparty.net<mailto:toasters-bounces@teaparty.net> [mailto:toasters-bounces@teaparty.net] On Behalf Of Basil Sent: Thursday, June 25, 2015 8:51 AM To: toasters(a)teaparty.net<mailto:toasters@teaparty.net> Subject: OnCommand Performance Manager events I'm using 1.0.0 r2 with a CDOT cluster running 8.2.3.

Has anyone had any experience with this software? Another question- is there a way to look directly at an aggregate's utilization?

cDOT 8.3: disk assignment

Hi, I've been configuring aggregates on 6 nodes cluster today and managed to assign a disk to a node that the disk is not "cabled" to, ie it sits in a disk shelf that is managed by a different HA-pair: na201::> disk show -container-type unknown Usable Disk Container Container Disk Size Shelf Bay Type Type Name Owner ---------------- ---------- ----- --- ------- ----------- --------- -------- 6.45.16 - 45 16 SAS unknown - na201node-3a The disk is "cabled" to na201node-1a, so I'm trying to change the ownership: na201::> storage disk assign -disk 6.45.16 -owner na201node-1a -force Error: command failed: Failed to assign disks. Reason: Disk 6.45.16 does not exist. OK, this time trying to remove the ownership: na201::> storage disk removeowner -disk 6.45.16 -force Warning: Disks may be automatically assigned to the node because the disk's auto-assign option is enabled. If the affected volumes are not offline, the disks may be auto-assigned during the remove owner operation, which will cause unexpected results. To verify that the volumes are offline, abort this command and use "volume show". Do you want to continue? {y|n}: y Error: command failed: Disk 6.45.16 is not connected to na201node-3a I'm out of ideas at this point .. any hints? Cheers,

snmp and cdot 8.3
by Sayla, Mustafa 22 Jun '15

22 Jun '15

Anyone has experience with monitoring CDOT 8.3 with snmp? I have configured the CDOT system and configured SNMP trap host and community string yet we are not receiving traps. We were told by our third party vendor Solar Winds that netapp does not use standard snmp OID. We are not using snmp v3.

Recommendations on preserving a filers data?
by Arnold de Leon 22 Jun '15

22 Jun '15

What are the recommendations for the "best" way to preserve a copy data on a filer for future use? Background: A company has ceased operations and wants to preserve copies of its data "just in case someone wants it in the future". All the interesting data has been copied to the a single "archive" filer. There are about eight volumes in using about 50TB (with dedupe but no compression). This will be backup copy #1. The other filers that previously held the data are being sold and scheduled to be wiped. The data is a mixed of virtual machines and file shares. Now I'm trying to see if if a way to make another copy of the data for safe keeping at a reasonable cost. Speed of restore would not be high the feature list of this secondary archive. One of the first thoughts simply dump the data onto an AWS volume for "cold storage". Sane? Tips/tricks? Data presumably gets scrubbed to prevent bit rot. Conveniently available just about anywhere. Has a recurring cost but avoids some upfront cost. Second thought is find a relatively inexpensive array of disks and dump the data to that. Most likely benefit is fastest to write to. Maybe cheapest but in the end all the data is on non-spinning disks without verification. Tapes? I don't like tapes. Don't know if a working tape system available but if there was is this a good case for it. Tape static storage better than disk? Thanks. arnold

Clustered ONTAP 8.2 routing
by Legato, John (NIH/NHLBI) [E] 17 Jun '15

17 Jun '15

Hello, We've recently acquired a 2 node FAS8020 cluster running Clustered DataONTAP 8.2. We inherited a rather unusual/silly network topology, in which we have two subnets (a publicly routable one and an RFC1918 one for internal use only) running on the same VLAN. In other words, there's no router between these two subnets. In Linux, we're able to get boxes on the publicly routable subnet to communicate with the internal subnet (10.1.0.0/16) as follows: route add -net 10.1.0.0 netmask 255.255.0.0 dev eth0 This command tells the Linux box that it can send packets to 10.1.0.0/16 hosts out eth0 without going through an intervening router. However, we've yet to find a way to do this with Cluster DataONTAP. We've played around with routing groups and routes, but we cannot figure out a way to tell Clustered DataONTAP to route through an interface. Does anyone know if this is possible? NetApp has advised us to set up a router between our two subnets. We share NetApp's concern over fail over We'll set up a router if we can't figure out any other way to make this work. Thanks John

issue with Ontap upgrade 7mode system
by Sayla, Mustafa 15 Jun '15

15 Jun '15

I recently upgraded one of my 7mode controller from 8.1P1 to 8.2.3P3 and ran into issue during the second controller upgrade. I installed the upgrade version on both the controller than performed the cf takeover from controller B to controller A and it went fine. I then waited about 10 minutes and did the cf giveback and that also went fine. after waiting another 10 minutes I tried the cf takeover from controller A to controller B and I got the version mismatch error. I then issued cf takeover -n and at the time controller A did not took over controller B but just rebooted controller B. This caused a downtime with our vmware farm as servers lost connection to the data store on controller B. This is with NFS protocol. I only see this error in the logs Fri May 29 15:53:59 CDT [rddata1b: cf_takeover: kern.rc.msg:notice]: vlan: interface creation failed due to internal errors Partner vlan create command failed This explains why the takeover did not work but does not explain why this happened in the first place. I have worked with Netapp and validated that the rc file is correct and we have done failover and failback in the past without any issue. I also did the failover and failback after this to rule out configuration issue but could not recreate it. I need to upgrade 3 more HA pairs and I want to know if anyone has seen this issue before and does this have anything to do with the upgrade.

cifs.smb2.client.enable
by Ray Van Dolson 15 Jun '15

15 Jun '15

cifs.smb2.client.enable This option enables SMB 2.0 client capability on the Filer. When this option is enabled, Filer-initiated connections to Windows servers use the SMB 2.0 protocol. If the Windows server does not support the SMB 2.0 protocol, the Filer uses SMB 1.0. If a session was established over SMB 2.0 and then this option is disabled, existing sessions are not terminated. The Filer continues to use SMB 2.0 for the existing sessions; new sessions do not use SMB 2.0. Probably missing something obvious -- but would someone describe to me a scenario in which the NetApp would act as a CIFS client? Thanks, Ray

unified manager for CDOT 8.3
by Sayla, Mustafa 13 Jun '15

13 Jun '15

We recently installed our first CDOT system with 8.3P1 and now I want to setup the monitoring and configuration environment for it. I have few questions * Do I need a separate OnCommand Server for CDOT or I can use my existing server that I use to manage my 7mode systems. My current system is using OnCommand 5.1. * We are on Vsphere 5.0 and per admin guide it seems like I cannot use Unified Manager 6.2 so can I use Unified Manager 6.1 with CDOT 8.3P1 * Is performance manager part of unified Manager or it is a separate appliance. What I want to know that if I download and install the unified manager appliance do I get performance manager as part of it or I have to download performance manager appliance separately and install it as a separate VM Thank you Mustafa Sayla Visit us on the Web at mesirowfinancial.com This communication may contain privileged and/or confidential information.

Mystery quota on qtree?
by Jeff Cleverley 12 Jun '15

12 Jun '15

Greetings, I have a 8.1.2 7-mode cluster and was asked to adjust a couple of quotas. The problem is there doesn't appear to be a quota set on the trees. If I cd to the top of the volume and do a "df -h .", I get the volume totals. When I go into any of the sub-directories, it shows me different numbers for size allocated and used. The free is consistent at all levels but not the size and used. I've looked at the /etc/quotas, quota report, and viewed it through OnCommand. Nothing shows a quota limit. I've also run pwd-P and the df -h . both show I'm in the same file system and have not followed a symlink. The space reservation is volume and guaranteed, and snap reserve is at 0% utilized and has not grown beyond it's reserve. Below is the best I can give for details. Thanks, Jeff [root@admin storage1]# df -h . ## top level volume Filesystem Size Used Avail Use% Mounted on filer2:/vol/storage1 2.4T 1.1T 1.3T 45% /net/filer2/vol/storage1 [root@admin storage1]# cd tools [root@admin tools]# df -h .
