  • NetApp and SQL Server?

    - by Edinor
    Do you have any good or bad experiences to share running SQL Server OLTP Systems on NetApp appliances? I have been working with a small, relatively low-volume cluster with a lower-end NetApp device, and I have found the environment to be generally unstable, at least compared to my experiences with other SANs, iSCSI arrays, and DAS setups. I struggle to believe that RAID DP and WAFL are more than fairy-dust technologies. A solution has been proposed to me that I just need a bigger, better NetApp, with PAM cards and other cool technology I've not heard of, and I feel like I would be better off spending a quarter of that on good direct-attached drives and a beefy server. At the same time, I feel that an Enterprise-class SAN should be something I can count on to be consistently a more stable, better performer than the less expensive solution I might propose. Are you a SQL Server DBA in an OLTP environment and love your NetApp? If you don't like them, why not?

  • Why your Netapp is so slow...

    - by Darius Zanganeh
    Have you ever wondered why your Netapp FAS box is slow and doesn't perform well at large block workloads?  In this blog entry I will give you a little bit of information that will probably help you understand why it’s so slow, why you shouldn't use it for applications that read and write in large blocks like 64k, 128k, 256k ++ etc..  Of course since I work for Oracle at this time, I will show you why the ZS3 storage boxes are excellent choices for these types of workloads. Netapp’s Fundamental Problem The fundamental problem you have running these workloads on Netapp is the backend block size of their WAFL file system.  Every application block on a Netapp FAS ends up in a 4k chunk on a disk. Reference:  Netapp TR-3001 Whitepaper Netapp has proven this lacking large block performance fact in at least two different ways. They have NEVER posted an SPC-2 Benchmark yet they have posted SPC-1 and SPECSFS, both recently. In 2011 they purchased Engenio to try and fill this GAP in their portfolio. Block Size Matters So why does block size matter anyways?  Many applications use large block chunks of data especially in the Big Data movement.  Some examples are SAS Business Analytics, Microsoft SQL, Hadoop HDFS is even 64MB! Now let me boil this down for you.  If an application such MS SQL is writing data in a 64k chunk then before Netapp actually writes it on disk it will have to split it into 16 different 4k writes and 16 different disk IOPS.  When the application later goes to read that 64k chunk the Netapp will have to again do 16 different disk IOPS.  In comparison the ZS3 Storage Appliance can write in variable block sizes ranging from 512b to 1MB.  So if you put the same MSSQL database on a ZS3 you can set the specific LUNs for this database to 64k and then when you do an application read/write it requires only a single disk IO.  That is 16x faster!  But, back to the problem with your Netapp, you will VERY quickly run out of disk IO and hit a wall.  Now all arrays will have some fancy pre fetch algorithm and some nice cache and maybe even flash based cache such as a PAM card in your Netapp but with large block workloads you will usually blow through the cache and still need significant disk IO.  Also because these datasets are usually very large and usually not dedupable they are usually not good candidates for an all flash system.  You can do some simple math in excel and very quickly you will see why it matters.  Here are a couple of READ examples using SAS and MSSQL.  Assume these are the READ IOPS the application needs even after all the fancy cache and algorithms.   Here is an example with 128k blocks.  Notice the numbers of drives on the Netapp! Here is an example with 64k blocks You can easily see that the Oracle ZS3 can do dramatically more work with dramatically less drives.  This doesn't even take into account that the ONTAP system will likely run out of CPU way before you get to these drive numbers so you be buying many more controllers.  So with all that said, lets look at the ZS3 and why you should consider it for any workload your running on Netapp today.  ZS3 World Record Price/Performance in the SPC-2 benchmark ZS3-2 is #1 in Price Performance $12.08ZS3-2 is #3 in Overall Performance 16,212 MBPS Note: The number one overall spot in the world is held by an AFA 33,477 MBPS but at a Price Performance of $29.79.  A customer could purchase 2 x ZS3-2 systems in the benchmark with relatively the same performance and walk away with $600,000 in their pocket.

  • NFS "Permission Denied" getting cached on NetApp Filer

    - by Christopher Karel
    We have a bunch of Linux boxes mounting NFS shares off a NetApp filer. From time to time, I will flub some part of the export configuration. Typo on one of the allowed hosts, incorrect IP address, etc, etc. No worries, this is usually done on a test system, or with brand new exports that aren't yet in production. However, I've found that once I've been denied permission to mount something from a Linux machine, the failure gets cached for as long as a day. I will correct the problem that was blocking the mount, re-export on the NetApp, and still not be able to mount the share. I'm pretty sure this caching is done at the NetApp side. It normally ages out after a day or so, but it really sucks having to wait until tomorrow to mount a share. I've tried exportfs -f on the NetApp, as well as dns flush. (I found both suggestions via Google) However, neither one works. I would sell my soul if someone could help out with a command/pagan ritual that would clear up this cache issue. --Christopher Karel

  • Heartbeat (Linux HA) and NetApp?

    - by Drew
    Does anyone have any experience setting up a high availability two node Linux cluster using heartbeat (linux-ha.org) and NetApp storage (preferably using SnapDrive for Linux)? Basically I would like to mount the same NetApp LUN over Fibre Channel to two servers in an Active/Passive mode (only one server can access the LUN at a time) Thanks!

  • Backing up SQL NetApp Snapshots using TSM

    - by WerkkreW
    In our environment we have a 3 node SQL 2005 Cluster which is on NetApp storage. We are currently using SMSQL (NetApp SnapManager for SQL) to take Snapshot backups of the data. This works great, but due to some audit requirements we are also forced to maintain some copies on tape. We have used NDMP in other places across the enterprise but we do not want to use it in this specific instance. Basically what I need to do is, get the most recent snapshot copy of the databases on tape, via Tivoli Storage Manager (TSM). What I have done is, obtained a basic Windows Server 2003 VM with SnapDrive installed, which is SAN attached and zoned to the NetApp, and I have written a batch file to do the following: Mount the latest __RECENT snapshot lun to the host, using a specific drive letter Perform a TSM based incremental backup Dis-mount the LUN This seems to work fine, except sometimes the LUN's do not mount due to some sort of timeout. Also, due to my limited knowledge of windows batch scripting, I have no way to monitor the success or failure of these backups since I do not know how to send a valid return code back to the TSM scheduling service. Is there a more efficient/elegant way to accomplish this without NDMP?

  • NetApp NDMP backup with BE 2010 R2 works, restore fails

    - by uuwe
    Hi, I'm having some issues with a new Backup Exec 2010 R2 installation. I configured a NetApp FAS2020 as an NDMP device and want to backup files from the NAS to a tape drive connected to my backup server. I set up ndmpd according to this document (http://www.symantec.com/business/support/index?page=content&id=TECH48957) and created a separate backup user (http://filers.blogspot.com/2006/09/setting-veritas-netbackup-with-non.html). Backup works perfectly, but restoring any file gives me an authentication failed error. The NDMP device has a "global" ndmp user configured in the device tab (tried this with the newly created ndmpd backup user and the netapp root) and I can also configure separate resource credentials in the BE restore job. I have tried setting the same accounts for the "global" ndmp device and the restore credentials and have also tried setting different accounts for them. NDMP debug level is at 5 and this is what shows up in /etc/messages. The session is closed immediately after it has been granted. 16:12:07 PST [Java_Thread:info]: ndmpdserver: ndmpd.access allowed for version = 4, sessionId = 51, from src ip = 192.168.11.17, dst ip = FAS2020-1/192.168.11.75, src port = 50857, dst port = 10000 16:12:07 PST [Java_Thread:info]: Ndmpd51: ndmpd session closed successfully for version = 4, sessionId = 51, from src ip = 192.168.11.17, dst ip = FAS2020-1/192.168.11.75, src port = 50857, dst port = 10000 Running wireshark on the backup server doesn't produce much. It shows a SYN - SYN/ACK - NDMP CONNECT_CLOSE Request from the backup server. The Resource Credentials for the restore job behave very oddly. If I enter NDMP credentials and do "Test All" it fails. If I use my regular domain backup account, it is successful. There are no failed or succeeded logons in the NetApp ndmp log and tracing this check shows that it doesn't even connect to the NAS. This makes me think that this is more likely flaky BE behaviour rather than misconfiguration of the NAS. Here is the options ndmp output: FAS2020-1 options ndmp ndmpd.access all ndmpd.authtype challenge ndmpd.connectlog.enabled on ndmpd.enable on ndmpd.ignore_ctime.enabled off ndmpd.offset_map.enable on ndmpd.password_length 16 ndmpd.preferred_interface disable ndmpd.tcpnodelay.enable off

  • Searching Netapp Network Share in Windows 7

    - by user121270
    Windows 7 famously does not do what its predecessor, Windows XP, did very well, index and search network drives! Sometimes, the logic of MS isd absolutely baffling. That siad, I am trying to find some solution to the issue, which is made more complicated by the fact that we are using a Netapp FAS 2020 as a CIFS fileserver. I know some of the solutions to the Windows 7 search index issue revolve around having a Search Service installed on a Windows 2008 server and then adding that server sahre to the library on the Windows 7 workstation. Is it possible to accomplish this in any way with a CIFS share on a Netapp filer?

  • Howto align partitions in Linux + NetApp

    - by santisaez
    NetApp support has suggested us aligning partitions to improve performance, in short: starting sector must be divisible by 8. How can I move the start point in a misaligned partition -in production, with ext3- under Linux? A screenshot with a misaligned (start=63s) and aligned (start=64s) partition is available at: http://filesocial.com/lkwvvn2 (If anyone is interested in this topic, NetApp has a good document explaining performance issues in misaligned partitions, search for "tr-3747": Best Practices for File System Alignment in Virtual Environments.) I have tried using parted "resize + move" commands, but when moving start point a get this error: (parted) resize Partition number? 1 Start? [64s]? End? [419425019s]? 419425018 (parted) move Partition number? 1 Start? 65 End? [419425019s]? 419425019 Error: Can't move a partition onto itself. Try using resize, perhaps? Using fdisk 'b' command in expert mode ('move beginning of data in a partition') works, but it doesn't move the file system.. thanks!!

  • NetApp and Hyper-V 2012 best practice/whitepapers?

    - by grimstoner
    We've recently acquired a NetApp/Cisco UCS solution, and I'd like to gather some background knowledge as to the best practices when setting up Hyper-V 2012 on such a solution. There is an upcoming seminar (in the Netherlands, http://www.realdolmen.com/nl/MSHyper-v-2012_NetApp), but it's in Dutch, and a couple of weeks away... Does anyone have some whitepapers/documentation about such a setup, or hasn't it been done before?

  • iSCSI connection timing out on ESX 3.5 against a NetApp storage appliance

    - by Jesse1973
    I get a timeout on iSCSI on different ESX hosts (3.5) at different times. It is puzzling, as both the ESX hosts as windows and other guests are experiencing timeouts. The iSCSI network is segregated on a private network. Here is an export of vmkiscsid.log from last night: 2010-02-10-12:30:38: iscsid: an InitiatorAlias= is required, but was not found in /etc/vmware/vmkiscsid/initiatorname.iscsi 2010-02-10-12:30:38: iscsid: LogLevel = 0 2010-02-10-12:30:38: iscsid: LogSync = 0 2010-02-10-12:30:42: iscsid: Login Success: iqn.1992-08.com.netapp:sn.101197719,default,192.168.73.2,3260,2001, 0x1 2010-02-10-12:30:42: iscsid: connection1:0 is operational now 2010-02-16-02:03:35: iscsid: Kernel reported iSCSI connection 1:0 error (1008) state (3) 2010-02-16-02:03:39: iscsid: connection1:0 is operational after recovery (2 attempts) 2010-02-16-04:02:27: iscsid: Kernel reported iSCSI connection 1:0 error (1008) state (3) 2010-02-16-04:02:32: iscsid: connection1:0 is operational after recovery (2 attempts) Should i edit the timeout value on the ESX host for iSCSI? This may work around the problem but will not solve it.

  • NETAPP Fragmentation

    - by mdpc
    We all know that once a disk (or storage system for that matter) gets introduced into use, the performance degrades due to fragmentation of files. This seems to be why disk defragmentors are in fairly wide use on Windows boxes. And they do increase the performance substancially. As an aside, I haven't heard of many defragmentors in the Unix/Linux area. Despite the claimed WAFL protections for the NetApp, file fragmentation still will occur, especially with all the sparsely crated VMs. My question is does anybody do any sort of defragmention of such a storage system? Do you notice any measurable degration/improvement of either not doing/doing anything to address this situation? Does anybody do anything about it? If so what? Thanks

  • SQL Server iSCSI session issue with a NetApp SAN

    - by Matt Beckman
    We had an issue early this morning when iSCSI issues broke connectivity with a few of our databases (resulting in a SQL Server Error 21). Attempts to DBCC CheckDB did not work, and the only solution was to restart the SQL Service. Is there a known reason why an iSCSI initiator session would reset itself out of the blue? Example below from the NetApp syslog. This set of errors was replicated 4 times (once for each SQL server in production). Only one SQL server was noticeably impacted, however. [san1: iscsi.notice:notice]: ISCSI: iswta, ISID Rule: new connection from same initiator, shutting down old session 7 [san1: iscsi.notice:notice]: ISCSI: iswta, New session from initiator iqn.1991-05.com.microsoft:sql1.example.corp at IP addr 10.xxx.xxx.123

  • Open NetApp CIFS Share

    - by kingfish
    I have a CIFS share on a NetApp device. I want this share to be completely open to any user/computer on the same network. I don't want any authentication (domain, workgroup, etc) required; no login/password should need to be provided. Currently I have CIFS configured to use "Domain - Windows 2000" authentication and have the permissions on the share set to "Everyone - Full Read/Write" but if you try to connect to it from a machine that isn't bound to the domain it is asking for login info.

  • NetApp erroring with: STATUS_NOLOGON_WORKSTATION_TRUST_ACCOUNT

    - by Sobrique
    Since a sitewide upgrade to Windows 7 on desktop, I've started having a problem with virus checking. Specifically - when doing a rename operation on a (filer hosted) CIFS share. The virus checker seems to be triggering a set of messages on the filer: [filerB: auth.trace.authenticateUser.loginTraceIP:info]: AUTH: Login attempt by user server-wk8-r2$ of domain MYDOMAIN from client machine 10.1.1.20 (server-wk8-r2). [filerB: auth.dc.trace.DCConnection.statusMsg:info]: AUTH: TraceDC- attempting authentication with domain controller \\MYDC. [filerB: auth.trace.authenticateUser.loginRejected:info]: AUTH: Login attempt by user rejected by the domain controller with error 0xc0000199: STATUS_NOLOGON_WORKSTATION_TRUST_ACCOUNT. [filerB: auth.trace.authenticateUser.loginTraceMsg:info]: AUTH: Delaying the response by 5 seconds due to continuous failed login attempts by user server-wk8-r2$ of domain MYDOMAIN from client machine 10.1.1.20. This seems to specifically trigger on a rename so what we think is going on is the virus checker is seeing a 'new' file, and trying to do an on-access scan. The virus checker - previously running as LocalSystem and thus sending null as it's authentication request is now looking rather like a DOS attack, and causing the filer to temporarily black list. This 5s lock out each 'access attempt' is a minor nuisance most of the time, and really quite significant for some operations - e.g. large file transfers, where every file takes 5s Having done some digging, this seems to be related to NLTM authentication: Symptoms Error message: System error 1808 has occurred. The account used is a computer account. Use your global user account or local user account to access this server. A packet trace of the failure will show the error as: STATUS_NOLOGON_WORKSTATION_TRUST_ACCOUNT (0xC0000199) Cause Microsoft has changed the functionality of how a Local System account identifies itself during NTLM authentication. This only impacts NTLM authentication. It does not impact Kerberos Authentication. Solution On the host, please set the following group policy entry and reboot the host. Network Security: Allow Local System to use computer identity for NTLM: Disabled Defining this group policy makes Windows Server 2008 R2 and Windows 7 function like Windows Server 2008 SP1. So we've now got a couple of workaround which aren't particularly nice - one is to change this security option. One is to disable virus checking, or otherwise exempt part of the infrastructure. And here's where I come to my request for assistance from ServerFault - what is the best way forwards? I lack Windows experience to be sure of what I'm seeing. I'm not entirely sure why NTLM is part of this picture in the first place - I thought we were using Kerberos authentication. I'm not sure how to start diagnosing or troubleshooting this. (We are going cross domain - workstation machine accounts are in a separate AD and DNS domain to my filer. Normal user authentication works fine however.) And failing that, can anyone suggest other lines of enquiry? I'd like to avoid a site wide security option change, or if I do go that way I'll need to be able to supply detailed reasoning. Likewise - disabling virus checking works as a short term workaround, and applying exclusions may help... but I'd rather not, and don't think that solves the underlying problem. EDIT: Filers in AD ldap have SPNs for: nfs/host.fully.qualified.domain nfs/host HOST/host.fully.qualified.domain HOST/host (Sorry, have to obfuscate those). Could it be that without a 'cifs/host.fully.qualified.domain' it's not going to work? (or some other SPN? ) Edit: As part of the searching I've been doing I've found: http://itwanderer.wordpress.com/2011/04/14/tread-lightly-kerberos-encryption-types/ Which suggests that several encryption types were disabled by default in Win7/2008R2. This might be pertinent, as we've definitely had a similar problem with Keberized NFSv4. There is a hidden option which may help some future Keberos users: options nfs.rpcsec.trace on (This hasn't given me anything yet though, so may just be NFS specific). Edit: Further digging has me tracking it back to cross domain authentication. It looks like my Windows 7 workstation (in one domain) is not getting Kerberos tickets for the other domain, in which my NetApp filer is CIFS joined. I've done this separately against a standalone server (Win2003 and Win2008) and didn't get Kerberos tickets for those either. Which means I think Kerberos might be broken, but I've no idea how to troubleshoot further. Edit: A further update: It looks like this may be down Kerberos tickets not being issued cross domain. This then triggers NTLM fallback, which then runs into this problem (since Windows 7). First port of call will be to investigate the Kerberos side of things, but in neither case do we have anything pointing at the Filer being the root cause. As such - as the storage engineer - it's out of my hands. However, if anyone can point me in the direction of troubleshooting Kerberos spanning two Windows AD domains (Kerberos Realms) then that would be appreciated. Options we're going to be considering for resolution: Amend policy option on all workstations via GPO (as above). Talking to AV vendor about the rename triggering scanning. Talking to AV vendor regarding running AV as service account. investigating Kerberos authentication (why it's not working, whether it should be).

  • NetApp FAS270 head doesn't see disks

    - by wfaulk
    I have an FAS270C. For months, I've been running it in a split-head manner (that is, with each head serving data totally independently, and without any clustering even being enabled) in order to facilitate moving some data around. I finally got everything situated, moved all the data to one of the heads, and was trying to get clustering set back up. Now when I try to install OnTap onto the "new" head, it cannot see any of the disks in the head shelf. (That is, the shelf into which the heads are inserted.) I've booted into maintenance mode, and it shows me that the 0b adapter, which should be the adapter that that shelf and its disks should be presented on, is in "OFFLINE (physical)" state. If I try to enable it with either "storage enable adapter 0b" or "fcadmin online 0b", it waits for about 30 seconds and then says: [fci.initialization.failed:error]: Initialization failed on Fibre Channel adapter 0b. [fci.adapter.online.failed:error]: Fibre Channel adapter 0b failed to come online. There is currently nothing attached to its external 0b port. I've tried it with and without an SFP plugged into it, and with and without its internal termination switch on. The currently active head can see those disks, and can see that two of them are assigned to the other head. Before I started reconfiguring, the "new" head could see disks on that shelf. They may even be the same disks that OnTap was installed on previously. Does anyone have any idea how to proceed?

  • MySQL 5.1.34 on NFS w/NetApp

    Is this still a bad idea? I know older versions of MySQL performed poorly with NFS. I imagine the issue lies with the usage of fsnc() and/or O_DIRECT. If the issues are mostly resolved, are there common pitfalls/gotchas, specifically around a large (multiple tables with tens of millions of records) InnoDB database that may see up to 20-50 reads/sec

  • Are there no downsides to NetApp SAN solutions other than price?

    - by flashkube
    We have pretty much decided on a NetApp solution for our first SAN. Given that, I've been tasked with finding as much reason not to go with NetApp as I can. We like to do this A) so we know what we're getting into and B) so we aren't clouded by the inevitable post vendor demo euphoria. I have scoured the internet for cons and can only find one: price. Have you had a nightmare experience with NetApp that you just want to get off your chest? Please, only people with NetApp experience. Thank you!

  • Can I get "disk utilization" from a NetApp filer via SNMP?

    - by Andrew
    On a NetApp filer's command line I'm running "sysstat -u" to show disk utilization, (actually the utilization of the single busiest disk). By disk utilization, I mean "percent of time the disk is busy", not "how much space on the disk is being used to store data/metadata". Is there a way to get disk utilization info through SNMP? The netapp.mib file doesn't appear to expose this. It does have CPU utilization, disk usage & capacity information, etc, but not disk utilization. The MIB-II (rfc1213) seems to be the only other information exposed by the filer through SNMP. I hope I am missing something. The "CP (consistency point) time" metric is exposed through the NETAPP-MIB in SNMP, but this seems to only partially correlate with disk utilization under write load, and not really at all under read load.
