Hmm. Is there anything useful under /var/log/messages ? I can't think of anything else. If you have NFS over tcp turned on on the filer you could try mounting it over tcp on the linux box.

Strange mounting problem (More info)
by Stephen C. Woods 05 Mar '01

05 Mar '01

We have a Dell Linux 7.0 system that can't mount from a 740 (5.3.4R2). However it can mount from a 540 (5.1.2R3), and also from a AIX (4.2) and Sun (2.6) machine with no problems. Packet sniffer indicates that packets are sent to the filer but never return. A little more info, the filer mounts OK to linux 5.2 (Red hat) and all sorts of other machines. The filer and the failing machine can ping, and telnet to each other. ----- Stephen C.

Silly question, is nfs licensed and turned on? On the console: type 'license' to see if it's licensed, type 'nfs' to get a status of the nfs daemon, and 'nfs on' to turn it on it its not. > -----Original Message----- > From: Stephen C.

Recent Field Alerts invisible at NOW?
by Chris Thompson 05 Mar '01

05 Mar '01

The last two Field Alerts (#78, 26 Feb and #79, 28 Feb) are visible in the full list <http://now.netapp.com/NOW/products/field/>, but in the "Field Alerts" section of my "customised home page" <http://now.netapp.com/Self-Service/Personal/usrPage.asp> only #77 and earlier are visible. At first I thought this might be some sort of local caching problem, but I think I have eliminated that possibility. Do you all see the thing?

Backups on F630 filers
by svawter＠c-cube.com 05 Mar '01

05 Mar '01

I have four (4) F630 filers (yeah, yeah, yeah, I know, upgrade!) and an additional two (2) F740 filers. I want to direct attach at least 1 drive from a library to each filer and I want to use Ultrium LTO libraries. Failing LTO support, I would like to use AIT-2 libraries. The problem that I have is that neither of these is officially support on the F630 platform! (AIT-2 is on the F740) Does anyone have AIT-2 running on F630? I don't want to run Mammoth, as I have heard too many horror stories (yes, I know that M2 beats AIT-2 by 2:1 for speed and by 10GB capacity, but that's irrelevant if the drive is down for maintenance much more often). Better yet, does anyone have LTO running on a Filer of any model, preferably a F630? (since they are barely shipping LTO, I doubt it). If you don't know what LTO is, go looking at HP, Seagate or IBM. Seagate seems to have the best drive at 16mb/sec with 100gb capacity and I think that this is due to a variable speed motor (which should also allow it to kick HP & IBM's butt when you can't keep data streaming in at 15mb/sec or better!)

Your choice for AIT-2 is solid (2 generations, backward read/write compatible, investment in media usable in later generations, less than 2% AFFR (raw field failure rate over the past 4 years)NDMP compliant, etc.etc. By the way, what have you heard about LTO's field reliability, cross-compatibility format compliance,(multiple manufacturers of LTO on the same format should be able to read data written by other mfgs. LTO units), media availability, and any actual backup/restore stories. I'd like to hear from anyone out there why they are looking at this format vs. sticking with DLT or transitioning from formats at the end of their cycles (DAT, Travan,etc.) 'Backup is worthless if you can't restore it.'

sounds like a filer routing problem on the problem filer netstat -r look for the problem Linux system this the correct interface and gateway? -----Original Message----- From: Stephen C.
