A few RedHat 7.2 nfs clients mounting a F840 volume via automount error out with the following. I have looked into everyting including NIS timeouts, filer sysstat, network performance and everything looks to be fine. Intrestingly all the other non linux Clients accessing the same auto-mount are working perfectly.

What are your mount options? We run NFS over TCP on all our machines, including hundreds of RH7.1 Linux boxes. No data corruption so far (or at least, we hope so ;-) -- Gregory -----Original Message----- From: Tom Felbinger [mailto:tom.felbinger@synopsys.com] Sent: Tuesday, March 11, 2003 4:04 PM To: toasters(a)mathworks.com Subject: RE: Weired Linux error A couple folks mentioned running NFS over TCP for linux. However, I've encountered data corruption (i.e. running a filer hosted binary will core dump) with RH 7.1 and 7.2 with NFS over TCP. Is there some patch/kernel rev/something I need to apply??? I stopped pursuing this because RedHat and NetApp said this was a known issue. Sounds like some people have it working though.

We have found that a Linux NFS v3 client using udp has this problem, but it goes away if you use tcp. I think Linux defaults to udp. You may need to enable tcp on the filer with options nfs.tcp.enable on

Re: Network Appliance's used equipment policies

Hello, Dan: NetApp's "Used-Equipment Support" policy described at http://www.netapp.com/support/ues.html does not support the following claims that are being made by some NetApp reps: 1) "The installation of used NetApp add-ons will void your filer's maintenance service agreement" 2) "If you buy used NetApp add-ons, you will be required to pay NetApp's recertification fee, even if you elect not to place these add-ons under your existing NetApp service contract" 3) "Used NetApp gear can only be purchased from "authorized" NetApp dealers" 4) "3rd party maintenance coverage is not allowed, as it will void your filer's software license agreement" 5) "Allowing hardware or software coverage to lapse will void your filer's software license agreement" We acknowledge that NetApp's standard policy is very clear with regard to "used software." However, NetApp makes exceptions, and as you know, Union Computer has resold many NetApp filers with transferable NFS, CIFS and CLUSTER licenses where Network Appliance actually processes the license transfers, free of charge.

Snmp traps
by Asbjørn Bjørkelund 11 Mar '03

11 Mar '03

Hello Toasters We are looking for some help for defining snmp traps, or to be more correct is there anybody who has already created lists with traps. i'm looking for 6-7 traps for example for Clusters: this filer is dead, Clusters: CFO this filer cannot takeover, CFO partner may be down, disk failed, power supply failed. Best Regards Asbjorn

Network Appliance's used equipment policies
by ferdberfl＠netzero.com 11 Mar '03

11 Mar '03

I'm getting so confused. This statement posted on Network Appliance's web site looks clear to me, especially regarding the transferability of software licenses. I keep reading these postings from Scott at Union Computer exchange and they don't look anything like what Network appliance specifically says in writing here: http://www.netapp.com/support/ues.html this looks kind of specific to me: All Network Appliance software license terms and conditions specify a "license to use," therefore software cannot legally transfer from one owner to another. Anyone purchasing used hardware equipment must also purchase new software licenses directly either from Network Appliance or from an authorized Network Appliance reseller. Software includes all protocols as well as streaming licenses, Snap products, and other software. Anyone trying to sell you "used software" would be violating the terms of the license. Support contracts such as warranty and maintenance agreements are also non-transferable ---------------------------------------------------------------------- -----Original Message----- From: ScottUCE(a)aol.com [mailto:ScottUCE@aol.com] Sent: Sunday, March 09, 2003 2:47 PM To: toasters(a)mathworks.com Cc: scott(a)unioncomputer.com Subject: Network Appliance's used equipment policies An active secondary market is developing for NetApp systems, parts, add-ons and maintenance.

RE: why should app care?
by Alan McLachlan 11 Mar '03

11 Mar '03

Farid, This is not a simple issue. Here are a couple of possibilities: 1) The application needs to do direct disk I/O (block level). In this case, you're out of luck using a network drive and should look at SnapDrive VLD or FCP. Examples: Microsoft Exchange 2000, some products like some FileNet modules that do block I/O. 2) The application does a check and won't install. However, you may be able to install on local disk then move the location to a network drive later. Example: SAP R/3 on SQL Server. Hope this helps. -----Original Message----- From: Farid Hamjavar [mailto:hamjavar@unm.edu] Sent: Tuesday, 11 March 2003 11:24 AM To: toasters(a)mathworks.com Subject: why should app care?

I have seen exactly the same nfs: not responding errors on some of my Solaris Servers. I also examined NFS at a very low level and showed no problems. Then I stumbled upon an article in NOW that explained the error to be harmless, more a nuisance than anything else. The performance of servers showing this error vs those not is virtually identical. However,I did not observe this error; Mar 9 06:38:36 linuxclient kernel: nfs: task 41929 can't get a request slot Mar 9 06:38:41 linuxclient kernel: nfs: task 43328 can't get a request slot Are you seeing any performance drops?

If you are using nfs version 3 on the Linux box, try these settings: filername:/vol/volpath /mntpoint nfs rw,bg,intr,rsize=32768,wsize=32768,tcp,noac,vers=3 If you are using a full-duplex network, you should not see any errors. If you are not, look at the output of ifstat and take, # of collisions + # of errors ------------------------------ divided by the total packets and multiple by 100%. The resulting percentage should be less than 5% or you definately have network problems. Hope this helps, --April ****************************************************** Sounds like RPC is working fine for you, otherwise NIS would have problems. Two thoughts, from when I've seen this in the past, for you: 1) Make sure you are using NFSv2. Linux NFSv3 is still fairly buggy. 2) Explicity define your read and write sizes. You might want to spec the retransmit as well, for now try adding the following client side mount options and see if things get better, if not tune the size alittle. Also don't use the intr option. use the options like this: mount -o rsize=8192,wsize=8192 server:/mount/point /localmount If these don't work for you, then sorry to say, it's a networking issue. Double check your NIC settings on the Linux client to make sure you are full duplex 100, if that's what your Filer is using. Use the linux tool "mii-tool" to check. Using "mii-tool -v" you can see what the current state is, and then use the tool again to force. If you exhast these, let me know. But one of the above should fix the problem. benr.
