Anybody using Solid State Disks for DB I/O intensive activities?
by Art Hebert 26 Apr '01

26 Apr '01

We currently have all of our database components on a f760 which is in a netapp cluster. Another set of redo logs is on the other filer. Has anybody used solid state disks to move their redo logs off of a filer to improve performance? If so what brand and what kind of improvement did you see? Thanks Art Hebert Email: art(a)arzoon.com <mailto:art@arzoon.com> Arzoon IT Dept. Phone: 650 522-6125 Mobile: 650 444-8667

RE: "Case survey" stuff from NetApp
by Tom "Mad Dog" Yergeau 26 Apr '01

26 Apr '01

After reading the other responses to this thread I'd like to reiterate some points others have made that I agree with: (1) A better description of the case would be helpful. Some of us open a lot of cases. (2) A survey for every case is too much. If it's just a drive replacement or a simple administrative task like updating the location of a filer, a survey is really not necessary. I tend to ignore all the surveys I get now just because I get ones for cases that don't justify a survey, and without a detailed description its not worth my time to go to NOW to figure out which case was which. (3) NOW is much more confusing and harder to use since the last redesign. It's also too slow. Also, PLEASE please please MAKE THE COOKIES PERSISTENT. Especially since it is so slow, it is a major PITA to have to sign in EVERY TIME I GO TO THE PAGE. WHY IS THIS NECESSARY? (Sorry about yelling but this bothers me a lot.) Haha. Venting. Thanks for listening.

I admit I throw them in the e-wastebin. It seems to me that providing only a method of returning these (probably only marginally meaningful) answers by e-mail is absolutely pessimal. If they really want to increase the response rate, surely NetApp should provide a method using forms at now.netapp.com? My vague recollection is that at one time a WWW-browser-based method was offered, but this doesn't seem to be the case now.

RE: Input/output errors from Linux clients?

Ditto here.

Ooh, *baguette*! Linux's NFS has been "okay" since the mid-2.2 kernels, and I've had no problems whatsoever with it as of 2.4. Yes, things were Bad in the past, but truly, honestly, surely, everything's okay now.

legato ndmp
by neil lehrer 26 Apr '01

26 Apr '01

hi, does anybody know an engineer at legato that really understands ndmp and how it is implemented in networker? we can't get it to work[with the correct version, patch, and enablers] and their customer service/techsupport has been very poor. since we already use legato for other things, management would prefer to stay with it. thanks.

Defragging / Balancing
by Andrew Siegel 26 Apr '01

26 Apr '01

Here's something that I've been curious about for a while: how does WAFL deal with fragmentation and balancing? For example, when you add a new disk to a volume, does DataONTAP/WAFL do any shifting of data to the new disk in the background in order to balance out disk usage across the volume? Does any kind of defragmentation take place automagically? (Is fragmentation even an issue with WAFL?) I ask because we are having just these issues with another manufacturer's journaling file system, requiring us to spend significant time and effort to stay on top of. -- Andrew Siegel, Head of Systems Blue Sky Studios, Inc.

More info on Input/Output errors...
by Nick's Lists 26 Apr '01

26 Apr '01

A bit more info I forgot to include in the first place along with responses to some other folks: We're using 2.2.16-21.7.1smp - We're holding off on 2.4 for now, as our vendor, VA Linux doens't feel comfortable with us moving up to 2.4 yet (I know, we are pushing it, but we don't want to go against their recommendations for now). If this problem is resolved in 2.4, then that'll be another thing to push us towards 2.4. Network wise - Transport is UDP This is occuring on clients in multiple sites, against 7 different filers as well. I don't see how it could be a network problem tho, but I'll go over the configuration of the filers. In all cases, the clients and servers are all on the same subnet, and in some cases, on the sames switch. I've verified that we are getting 100 mbit full duplex negotiation to the switch. Andrew - good suggestion on the soft vs hard. I'll go over my logic for that, and try to figur eout why we're doing that. It may be ahold over from when I had a <insert name of compeditors product here> that was heavily loaded and was responding very slowly. The thing is - other OS's aren't experiencing this problem in this environment, just the Linux boxes. That leads me to think its not a common problem like network of filer config.

FW: More info on Input/Output errors...
by Mark Baenziger 26 Apr '01

26 Apr '01

We had nearly identical problems with our Linux boxen (various kernels 2.2.5-2.2.14) running off of our filer. We tried dozens of different NFS settings without any luck. The only thing that finally got all of our NFS problems under control was going with a custom kernel with all of trond's various NFS patches in place. RFC compliance is a wonderful thing. Go ahead and compile new kernels with patches in place. Patches for various kernels are at http://www.fys.uio.no/~trondmy/src/. Additional information is (of course) at http://nfs.sourceforge.net/. You do not need to go with a 2.4 kernel for this; these patches can be applied (with varying levels of success) for kernels from 2.2.14 on up.
