Service is also an important factor, which NetApp is +very+ adept at. David, if you buy F330s, though, make sure they send you BLUE NettApp tee-shirts. We bought a pair of F330s last fall and are still waiting for ours. Maybe their sales department needs to take lessons from their support department... ho hum! -Caroline

Considering buying an F330
by David Drum 28 Mar '97

28 Mar '97

Hello anyone and everyone, I found the article announcing this list on comp.protocols.nfs via Deja News. Rather than lurk for a while, I need to jump right in and ask a leading question: If you the choice to make again, would you buy another Network Appliance, or would you get the biggest disk array you could find for the same money? Why? We're about to buy an F330, and I am in search of decision reassurance. I can't help but think I am splurging some. Regards, David K.

Re: "DU" lying on sunos5 machines
by Amy Chused 20 Mar '97

It's 'cuz Solaris du counts blocks, not K, and the netapp blocks are 16K, not 1/2 K. I think there's an option to du to tell it how big the bloody blocks are or to make it count K, not blocks. 'Course, if I remember correctly, that option is broken in the stock install, but there's a patch available from sun that fixes it, I think.

DU Lying to me on Sunos5 (last word)
by Jim Fondren 20 Mar '97

20 Mar '97

Hello again, Just a last update on my problem with DU which has now been happily resolved. :-) The patch for sol 2.5 (2.5.1 includes it) is now up to 103477-07. I'm mirroring it at ftp.cartotech.com/pub/sunpatch/103477-07.tar.gz Symptoms are DU returning erroneous info on filesystems mounted from a NETAPP device using NFS V3. Thanks, Jim F CARTOTECH

DU lying on sunos5 machines (update)
by Jim Fondren 20 Mar '97

20 Mar '97

Thankyou to all that responded. Your hints let met get closer to a solution. http://puma.join.ad.jp/tech/faq-e/sun/solaris2/Q5.51.html ...contains a related reference and mentions a patch to 2.5, 103226 (SPARC). Apparently solaris 2.5.1 doesn't have this bug (and I verified that on one of my 2.5.1 boxes).

Theis is a known bug in SunOS 5.? Their nfs client/server code has a bug in it that makes du report wrongly. There are patches available. (I can't remember offhand what their IDs are, though) regards, ---Ketil Kirkerud, Scandinavia Online

Write operations using NFS v2?
by Ragnar Lonn 18 Mar '97

18 Mar '97

Hello, Thought I'd try out this list in the hope of sharing some info with others as opposed to bugging NetApp support only for my own sake ;) (but I'll CC them at least) I'm setting up an F540 as a newsspool NFS server. That is, I will store Usenet news articles on it. A handful of machines will mount the filesystem read-only and these machines will accept user newsreader connections. Then I will have one single machine that mount the filesystem read/write - it will be the machine that stores incoming articles and removes old ones from the filer. Now, for news I've got the advice to use NFS v2 because clients using v3 issue the readdir+ operation unique to v3 and this operation does some extra stuff (as opposed to v2's readdir) that most applications take advantage of but news software (INN nnrpd) has no use of the extra data returned by readdir+ and this makes it a performance loss to use v3 in this particular case. But... I've read that NFS writes are much faster in NFS v3 than v2. This, of course, leads me to my question (ta-daa) : Actually, I'll make it two questions. If the anser to the first one is no, the second one is not so interesting anymore ;) 1. Are write operations slower on a NetApp server if you use NFS v2 compared to when you're using NFS v3? (and if so, about how much does it differ?) 2. (if the answer to the above question was 'yes') Could I leave the option "nfs.v3.enable" ON, on the NetApp and mount the filesystem from the reader clients using e.g "mount -o vers=2,proto=udp" (can't remember the exact syntax) while at the same time, from the client that is supposed to be doing a lot of *writing* to the NetApp, mount using version 3 to speed up the writes? This machine won't be running nnrpd so it won't be doing any readdir+ in vain. Regards, /Ragnar, Algonet

I'm going to turn off v3 on our NetApp box tonight, just to see how much of a difference it makes. Another thing I've been wondering about is options.minra. I find the documentation a bit thin, shall we say. If the 'aggressive read ahead' mentioned in the documentation is *per file*, it's probably a good thing for a NetApp used as a News spool - since you normally retrieve a whole article at a time. If the read ahead is based on something other than file, I'm not so sure. Anybody played with minra on a NetApp news spool? Steinar Haug, Nethelp consulting, sthaug(a)nethelp.no
