"Unable to send_ errno = No buffer space available" errors on F740
by Greg Earle 10 Apr '07

10 Apr '07

Greetings, fellow Toaster-ites. Hopefully this will distract you from the previous l1nux4411 "I'm 16 and Linux r00lz" troll-fest ... We've got a creaky old F740 running 6.3.1R1 that's performed yeoman duty for us for many years. All of a sudden it's having regular (at least once an hour) issues with "No buffer space available" errors that cause temporary NFS mount hiccup issues. I'm not sure how bad the situation is but it hasn't happened to us before (we also had our first panic on the F740 the other day, too) and more to the point, a reboot didn't fix the problem - it came right back shortly thereafter. Which is what worries me - a reboot should've fixed the issue, at least for awhile. I'm also troubled that there doesn't seem to be any tunable options parameter to increase the number of kernel buffers (or kernel buffer space in general) to deal with this issue. Has any other Toaster-ite run into this before? Here's the configuration and the error messages below.

I think our support contract may have expired (our F740 is obviously EOL'ed and frankly, we had expected to be completely moved off of it and onto our SAN by now, but the wheels of industry grind slowly around here), so I don't know what the status is of that. We keep getting the NetApp Field Alerts, but I don't know if that indicates we still have a valid service contract or not. (And the guy who used to handle our NOW account left and moved down to Costa Rica) Other than knowing that ONTAP 7.x doesn't run on an F740, what's the latest version that does? (Assuming I can find out whether we're still entitled/able to get ahold of it) - Greg

Linux on netapp filers
by linux4ever＠hushmail.com 10 Apr '07

10 Apr '07

Hello, we received a couple netapp filers and have some questions about upgrading them. 1) what version of linux will run on these filers (preferably gentoo) and what is the upgrade procedure? 2) setting up volumes does not allow me to format them with EXT3 or ReiserFS currently so i will need to know how that is done for increased filesystem performance and reliability 3) what brand/type of off the shelf disks will work with these systems? -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Linux is the choice of a GNU generation -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- -- Click for free info on online degrees and make $150K/ year http://tagline.hushmail.com/fc/CAaCXv1WBTAcV0HTxGkWPENUHMqa3zaJ/

to use anything but 100% open source in the enterprise is a moral crime. no company should pay money for closed source evil platforms that do not strive to increase the common good. plus linux outperforms just about anything on the market when you do it right. why would we want to support microsoft or companies that engage in the killing of third world people and put profits in front of mankind? we dont want a linux server just a nice appliance that we can put linux on and use proven technologies like ext3 or reiserfs and serve up our open source content. i strongly doubt WAFFLE is as robust or fast as similar linux raid filesystems. perhaps if netapp switched to linux they could also help the environment and help companies too but i dont know much about if they care about the people >On Mon, 09 Apr 2007 10:04:30 -0700 Blake Golliher ><thelastman(a)gmail.com> wrote: >>Installing linux on an awesome box like a 940 is pretty insane >>dude. >>As a server, you might find it underpowered.

Installing linux on an awesome box like a 940 is pretty insane dude. As a server, you might find it underpowered. It's got 6g of memory, and 1.6 P4 Zeon processor (two I think). While you can get a modern Dell 1950 with a dual core Intel proc and 8g of ram for around 6k. Maybe you got a smokin' deal on the 940? Maybe you have no support, or any licenses on this box? I'm not sure you are going to get what you want out of this. A 940 is an awesome OnTap platform, for NFS block storage. As a platform for Linux or BSD, it might not be the best of choices.

number of disks in an aggregate ?
by John Foley 09 Apr '07

09 Apr '07

Hi all, I wanted to ask the collective wisdom out there about how many disks to put in an aggregate. I have an F825 with 2 DS14 shelves, currently set up as 1 aggregate (so 28 disks in the aggregate), double parity, and 2 spares. I will be adding another DS14 shelf, identical disks as the other 2 shelves. My preference is to just extend the existing aggregate to 42 disks, and set up another volume for the new data that will be going on there - but I believe NetApp says that 28 disks is the max for an aggregate. So, question is - anyone out there using more than 28 (like 42 !) disks in an aggregate ? Is it possible ? recommended ? I thought that the more disks the better in an aggregate for performance reasons, but I thought I'd see what you all say !

Weird NFS need
by Glenn Dekhayser 08 Apr '07

08 Apr '07

So I figured I'd give the group a shot at this. I've got a client that wants to have 2 linux-based ftp/http servers, one in the LAN and one in the DMZ, share some data. NFS would be perfect. However- The security group will not allow server in the DMZ to access the LAN-based Netapp through the firewall for its NFS resource. Also, I cannot put an interface from the Netapp into the DMZ. They WILL allow it if it's encrypted. I saw WebNFS, does Netapp support some sort of NFS over HTTPS? or SSH? Alternatively, the client said that what would be allowed is if the two servers could share the same LUN- FC only, no iSCSI. Has anyone out there tried that before, what needs to be done on the linux side to make that happen? Thanks Glenn (the other one)

RE: Tools for managing filer content

For cifs my favorite when I looked at it was filecensus Not cheap though -----Original Message----- From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com] On Behalf Of jbrigman(a)nc.rr.com Sent: Saturday, 7 April 2007 7:34 AM To: toasters(a)mathworks.com Subject: Tools for managing filer content Hey Toasterz; Are there any free software tools which might run on a filer's server host (whether Linux or Windoze) for managing content on a filer? I'm looking for something I can run, preferably as a cron job or a scheduled job. I'm envisioning something that will let me configure a "control file" list of names of files to look for on the filer, then the program would walk the shares and exports and tell me how much space is being taken up on the filer by each file type. Even just a perl script would be great. I do have a windows app called Treesize Pro (which is not free) I use to get a snapshot of occupancy of various CIFS shares. It's useful and is the best thing I've got at the moment. But I'd like to have something I could script to send out a report summary providing both the overall occupancy of a volume plus a breakdown of what's in the volume.

ONTAP supports IPSEC. That should work, but it will increase the CPU load on the filer. I don't think it's an issue for HTTP/FTP setups, but it might cause problems with heavy PPS environments. What I don't understand is if the data their sending is basically unencrypted (HTTP and FTP?!??!) why does the NFS component need to be super secure from "teh hax0rz."?
