We currently run with NFS v2/UDP on our NetApp. The change from v3 to v2 resulted in a noticeable decrease in expiry time for us. The disadvantage of NFS v2 is that you won't be able to get number of inodes (files) via NFS. I like the suggestion from Guy Harris to deal with this: Use two mount points for the NetApp file system - one NFSv2 for the main News spool, and one NFSv3 to be able to check inodes, selected by suitable mount options on client.

mixing 4Gb and 9Gb discs
by Tom Yates 05 Jun '97

05 Jun '97

here's the situation. i have an F330, currently with 20 4Gb discs in three shelves. it is not performance-bound, it's capacity-bound. i'd heard (from netapp) sometime back that, at some future date, mixed 4 and 9 arrays would be permitted, but that i couldn't remove existing 4s, and that 9s would require a dedicated shelf. therefore, i'd tried to keep my disc load on three shelves, and so far succeeded. if i understand correctly, whilst i will shortly be allowed to mix 4s and 9s, i won't be allowed to use a full set of 9s - in fact, i'll be limited to 21*4 + 3*9 for data, with one hot spare and one parity, leaving me two disc slots i can't use. is this in fact the case, and if so, would anyone care to try to explain why, *bearing in mind that this toaster is definitely not performance-limited*?

CIFS and HTTP performance
by Aamer Latif 22 May '97

22 May '97

I have a couple of questions regarding CIFS and HTTP performance on NAC filers. Appreciate any answers regarding these. In reviewing the CIFs performance white paper on the NAC website (http://www.netapp.com/technology/level3/3015.html), I'm unclear on what type of NetBench test is being run. Specifically, I'm not sure if the paper describes NetBench Disk Mix or Random Read/Write tests. I'd thought that the graphs pertained to the Disk Mix test but block size variation test (section 3.1 in above paper) made me think that perhaps Random Read/Write test was being described (Disk Mix does not allow the I/O block size to be varied? If the Read/Write test is being used, I would be very interested in knowing the file sizes that are being used in these tests. Second, I'm wondering if there is any info or experiences regarding how many http op/s can a Netapp Web filer support? Thanks! Aamer a.latif(a)ieee.org

serial port
by Tom Yates 22 May '97

22 May '97

if the serial port on an F330 seems to be "wedged", ie seems to be operating at the wrong speed, spitting back junk characters, and the like, is there any way to clear it without resetting the toaster? i have high confidence in the terminal being ok as it's on a serial switch between my two F330s, and the other one seems fine. i have tried the "busted" toaster on all three other ports on the serial switch, so i don't think the problem is there, either. just curious. tom yates unix chap

F520 slots?
by Jim Davis 21 May '97

21 May '97

I'm looking for info about how many expansion slots a F520 system has -- if that's at www.netapp.com then I'm overlooking it. We're looking at a system with 64, maybe 128MB RAM 2MB NVRAM 3 disk shelves 1 network card and I'm trying to find out how much room for future SCSI or networking cards that would leave.

problems with F220 and INN on BSD/OS 3.0 (NFS v3 over TCP)
by Chris Caputo 06 May '97

06 May '97

Hi. I am new to the list. Is anyone else having problems with INN's fastrm not actually deleting all files it intended to delete when used on BSD/OS 3.0 with an F220? /bin/rm seems to work fine and in looking at the code the major difference seems to be that /bin/rm stat()'s each file before unlink()ing whereas fastrm just unlink()s. I am working up a version of fastrm that always stat()s first to see if that makes a difference. Any similar experiences? Chris

write lock
by Tom Yates 05 May '97

05 May '97

one of my F330s in back in write hell: during large chunks of the working day, the "disk write" statistic is non-zero (extremely non-zero) most of the time. given that i'm maxed out on NVRAM (8Mb), is there anything i can do to tune things?
