NFS v3 tcp brokenness....
by alexei＠cimedia.com 01 May '97

01 May '97

Tonight my filer stopped serving NFS over its FDDI interface. Twice. I called NAC support, got a call back, they had me take the interface down and back up. That fixed it temporarily. It was then reccomended that I disable the tcp extension (of course, it involves some work on the client side as well; joy). I did it and now it seems to be happier. My beef with NAC is that the tech guy said that there had been many problems like this, alot of open tickets in the support queue and that the next release of the OS would have the tcp option disabled (as the default; not removed). Why in the world has NAC not sent out an advisory about this? If it has been causing so many problems, the least they could have done is let us know that it could happen. Since this is a new filer (f540, 256MB read cache, 8MB nvram, 100GB, 2x100bT, 1 fddi), the problem only affected some setup stuff I was doing. The problem seems worse with fddi than with ethernet connections (my mounts that occured over ethernet were fine while the fddi ones were not). Anybody from the peanut gallery? Alexei

toaster testing.
by Michael Salmon 29 Apr '97

29 Apr '97

We are about to loan a toaster to see how well it performs in our environment (mixed Sun/Auspex/pc, NFS/SMB, ATM(Fore)/Ethernet). Does anyone have any tips about toaster weaknesses that we should try? We aren't trying to run down NAC, all systems have weaknesses, it's the one that you don't know about that are troublesome. /Michael -- /--------------------------------\ ___ | Michael Salmon | / \ | Ericsson Utveckling AB | / | | ÄS/UAB/Z/IPE | / _| | Box 1505 | / | | 125 25 Älvsjö | / / | Sweden | / / | | | | +--------------------------------+ | \ | Michael.Salmon(a)uab.ericsson.se | / *| | | / _/ | Tel: +46 8 727 30 74 | | | | FAX: +46 8 647 82 76 | | / # | GSM: +46 705 902 842 | | __// \--------------------------------/ |_/ "*Real* wizards don't whine about how they paid their dues." -- Quentin Johnson (quent(a)atanasoff.cs.iastate.edu)

Re: 9Gb discs for F330s

Are there any issues we should know about mixing different sized disks on the same system? I know it will work but is it something I should avoid? regards, Steve Gremban gremban(a)ti.com ------------- Begin Forwarded Message ------------- >this is great, and many thanks, but as someone who has only two slots left >in the third shelf of each of his F330s, and will need to know what to buy >shortly, could you give some indication of the timescale for the official >announcement? > >thanks. > > Tom Yates - Unix Chap - The Mathworks, Inc. - +1 (508) 647 7561 ------------- End Forwarded Message -------------

Since I happen to be an official spokesperson for product related issues, I'll defer product details and schedules until the forthcoming announcement. NetApp expects to support 9 GB disks on all our current filers: NetApp F220, F330 and F540. Configuration details will be provided at product introduction time. Cheena

would anyone care to comment on when we might expect to see 9Gb discs approved and available for the F330, and whether different shelves will be required?

NetApp reports
by Christoph Doerbeck 18 Apr '97

18 Apr '97

Greetings, I've recently been approached by management and asked to produce some weekly/monthly reports on our F330's. Do you have any suggestions on which technique provides the best reports? Are there pubically available scripts you might recommend? ++-------------------------------------- Christoph Doerbeck Motorola ISG / DIS Mansfield, MA.

Reporting Statistics on NetApp's

I apologize for the lack of detail. Our admin who had been in charge of our NetApps has recently left, and now the maintenance of these systems has fallen into my hands. The reports I've been asked to generate focus mainly on who/what users are consuming most of the space. We would also like to chart growth in order to predict expansion needs. These items are not very technical, but given the added overhead of NFS and the .snapshots, I was just curious to know how others monitor their Network Appliances. Are there any cool tricks? I guess that means "disc-usage related"... ++-------------------------------------- Christoph Doerbeck Motorola ISG / DIS Mansfield, MA.

F540 crashes while unlinking many files, Assertion failure?
by Ragnar Lonn 17 Apr '97

17 Apr '97

Hello, I have a Netapp F540 that has some 2-3 million files on its filesystem currently. I've been testing a news server setup on it and now I'd like to erase all these files, starting all over again with an empty filesystem. I did "rm -rf <dir>" (and no, I didn't erase the /etc dir on the Netapp) and it ran for a while, erasing lots of files, then the Netapp crashed and rebooted! I hoped it was a freak occurance so I did another rm when it got back up again but that made it crash once more. Now, I'm thinking this may have something to do with the snapshots. Because this is a newsserver I used "options nosnap on" following advice I got from people at Netapp. I also tried enabling snapshots and doing "snap sched 0 0 3@1,9,17" (just to test if it would make a difference) but the machine still was still prone to crash. I know the snapshot reserve may be too small - can that cause the server to crash like this? Yesterday I started an rm job and the F540 crashed at 2am this morning with the following message: PANIC: ../common/wafl/write_alloc.c:770: Assertion failure. version: NetApp Release 4.0.1c: Wed Jan 8 05:53:54 PST 1997 cc flags: 1 .dumping core: ........................................done ...it rebooted and ran until, I think, 4 am when it gave the same message but this time it didn't go online again because an old core file was present apparently: .Old core present on disk --- not dumped. This time it just halted. I think I read somewhere about this write_alloc.c:770: Assertion failure message/bug/whatever but I can't remember where. Can I just tell the Netapp to reboot again from the "ok" prompt or should I do something else? How do I make the machine *not* crash when erasing lots of files? Also, is there some way to re-initialize a Netapp server to the state it was when shipped? Doing a separate unlink on each file when you have several million files can be very time-consuming even if the server doesn't crash ;-) Regards, /Ragnar, Algonet
