I myself have observed high error rates on the Quad 10BaseT card on the filer. It was clearly the largest source of errors on the network, and much higher than I'd ever seen on a normal network. Moreover, it seemed that the error rate increased which each port (I don't quite remember if it went from A to D or D to A) without correlation to the actual amount of traffic on those ports. A bug was filed on this. However, these errors never seemed to actually be a major problem for the network and while I suppose they were responsible for the occasional performance anomaly overall performance of the filer was never a problem.

Note that collision is not the same as error! On standard half-duplex Ethernet, a collision is a normal and healthy phenomenon - simply means that the Ethernet flow control meachnism is working. It's okay to be worried about high error rates. High *collision* rates (as long as we're not talking about "late collision") aren't really all that meaningfull by themselves - what you should probably look at is the *utilization* of the Ethernet segment.

Toasters list - any FAQs?

I'm new to this list, so forgive my ignorance... are there any FAQs or digests of past list submissions that I can come up to speed with??? Also, here's a real item: I'm seeing fairly high error and collision rates on my F330's quad ethernet card, (10BaseT Quad-Ethernet Controller (Znyx)) and was wondering if there are any known issues with this card, since the network traffic on these four nets does not warrent this high error rate (I'm on OnTap 4.3.1). -- Jim Morton, Applix Inc., Westboro, MA jim(a)applix.com

OnTap FIler OS Upgrade Q's
by Weeks, Thomas 08 May '98

08 May '98

Hi all... Have a NA FS230 box running 4.2aD9... I need to do CIFS inter ACL/UFS-permissions testing and evaluation (for our NFS-->CIFS migration) and was PLANNING on going to 4.3.3 because I do not have a "test box" and wanted to protect myself from the possible "problems" associated with going to the full 5.x release and then trying to back out. (yes.. I am planning on EVENTUALLY going to 5.x, but I want to address one problem at a time (i.e. don't want to have to adress UFS/ACL/locking issues AND variables associates with backing out of the 5.x upgrade.. that's all)) Does anyone have any information on this subject that I should examine? I guess 4.3.3 is no longer the highest pre-5 release version.. but it is now 4.3.4? Anyone? Thanx...

Does anyone know how well the Breece-Hill Q1-15 (single drive, 15 cartridges) DLT tape stacker plays with the NetApp 630? Does anyone know how well the smallest StorageTek DLT tape stacker plays with the NetApp 630? I'm about the buy a new netapp and I'm trying to decide between these two tape drives for a locally attached tape drive. Any comments, please? Amy

F330 running at 100%

Greetings, Today we experienced an F330 pegging at 100% CPU. netstat and nfsstat didn't reviel anything eye popping, and so I'm asking for suggestions as to what might cause this? I would guess that a network interface shouldn't be capable of causing this, but I'll let you tell me....

Odd, our problems seem to stem from mailtool / procmail interaction. It doesn't look like mailtool is freeing locks, so procmail can't write to the spool. But this didn't occur (at least procmail didn't complain about) before we moved the spool from the 4.1.3_U1 mail server to the NetApp. >In all of the mess, we learned a couple of things to look for: Is there a >cron job on the Sun that clears locks older than a few minutes?

If I could just get them to use something other than mailtool, I wouldn't have a problem. pine, elm, nmh, qpopper, and Netscape (movemail) all seem to be ok. mailtool seemed to be fine when mounting from the 4.1.3_U1 spool, now it's brain-dead. >Good luck.

file locking problem
by Jason D. Kelleher 01 May '98

01 May '98

This past Saturday we moved our mail spool from a SunOS 4.1.3_U1 system to our NetApp F330 running ONTAP 4.3.3. Since then, we've had problems with procmail processes hanging on open file locks. This only occurs when someone leaves mailtool or dtmail running. Does anyone have any idea why mailtool won't handle file locking when mounting the spool from a NetApp, but will when mounting from a SunOS system? Any insight would be greatly appreciated. jason --- Jason D.

I would try applying the numerous patches for 4.1.3_U1, particularly the NFS patches and the mailtool patches from your descriptions. I might also check out upgrading to 4.1.4 and it's associated patches. Actually, I'm assuming your clients are the same flavor as your old mail spool server. If you have Solaris 2.x clients, there are patches for them as well. If the problem still persists you can talk to Netapp, probably get them a trace and they can find out who isn't doing locking correctly. Bruce
