Backup F720 with Legato/NFS
by Sanborn, Ed 03 Sep '99

03 Sep '99

Hi all, Does anyone have experience backing up a filer with Legato via NFS? So I need to just backup the snapshots, eh? Legato doesn't backup NFS partitions by default so I'm assuming I'll need a custom directive, right? Does anyone have an example directive? My Legato (version 5.0) server is a Sun running Solaris 2.6. Thanks, Ed Ed Sanborn (978) 691-6496 Northchurch Communications Inc. 5 Corporate Drive Andover, MA. 01810 Fax (978) 691-6300 http://www.northchurch.net <http://www.northchurch.net/>

Web Hits per NFS ops/s ?
by beepy＠netapp.com 03 Sep '99

03 Sep '99

Hey, hey. Without divulging corporate secrets, does anyone have rules of thumb for some "normal" activity, how much NFS traffic if generated out the back of a beefy Web Client to a filer that is serving up the pages via NFS? Rough feels and spreads is all I was curious about... I'm not sure I have ready access to a Web front end/filer back end setup that would be meaningful... Mostly I'm curious. (The number just thrown out, with no justification, was Each "hit" results in 5 NFS operations. I'm sitting here pounding my head trying to understand the "5". V3 might yield: LOOKUP ACCESS READ Per page hit. Is average object size 8 - 12KB? So one read on V3? I assume Apache front ends are not "browsing" they're firing names at the filer. Etc. I thought it an interesting question. What does the op mix look like for a filer backing a Web host? (I've seen the mix, I guess I was never startled enough to remember, seemed boring with lots of LOOKUPs, 10% READs, 5 - 8% WRITEs?). beepy

RE: Anyone mounting filer on Linux with smbfs ?
by Sam Schorr 02 Sep '99

02 Sep '99

Stephen, We are mounting multiple filers (2 F740's, 2 F760's), running OT 5.3.2D2, using NFS on Linux running on a Compaq. We are almost exclusively a CIFS environment and had wanted to do exactly what you want. However, there are known problems with OT that prevent using Samba (for example) to do a direct CIFS mount. So, we have a mixed ACL on the filers, run both CIFS and NFS, and mount the filers from Linux as NFS. It does require some tricks with WAFL settings to insure that non-trusted UNIX users are defaulted to the proper NT user domain account, and you have to make sure that the wafl options for unicode are set to both convert and create. If you convert from 5.2.x or prior, and your filer data has been created through CIFS, you will HAVE TO go through some procedure to open every directory to force conversion. If you do not, any directory not converted will be inaccessible in its snapshot, and snapshots cannot be converted. --srs -----Original Message----- From: Stephen C. Losen [mailto:scl@sasha.acc.virginia.edu] Sent: Thursday, September 02, 1999 12:54 PM To: toasters(a)mathworks.com Subject: Anyone mounting filer on Linux with smbfs ? Linux provides a SMB fs type and we are trying to mount a netapp CIFS share on a linux box, but with no luck. We are using unix authentication on the filer from a NIS map. We have no Windows or NT authentication set up at all. Windows and NT attach to CIFS shares on the filer just fine, using cleartext passwords. And they also attach to a linux samba server just fine, with unix authentication and cleartext passwords. But we can't get linux to mount a smb fs from the netapp. We would like to do this because we expect a large number of users to run linux on their desktops and we would love to not have to manage the exporting nightmare that NFS would require -- especially when most folks will be getting IP addresses via DHCP. It would be much more convenient (for us sysadmins) for linux users to just mount their home dir as a smb fs type, and they authenticate with their unix password.

Has anyone been able to get FrontPage 98 extensions working with Netapp filers?
by Mike Ball 02 Sep '99

02 Sep '99

I am running Data Ontap version 5.3D20 on F230 authenticating to NT 4.0 domain. We are unable to access web pages created in FrontPage 98 stored on the Netapp. The error I receive when I try to access the pages states "credentials passed by the client do not have access to the particular resource. Unauthorized due to ACL on resource". Has anyone been able to run FrontPage extensions on the Netapp? Thank you, Mike Ball mball(a)opensystems.com

RE: DLT problems on F740s

It's been my experience that "differential" SCSI drives as well as terminators are clearly marked as being such. Best Regards, Paul -----Original Message----- This sounds remarkably similar to the symptoms I saw when I accidentally plugged a single-ended (i.e, non-differential) DLT4000 into our F740. I removed the drive after I noticed it was hanging at a similar point to where yours was, and all was well. I've since had a wide differential DLT7000 on the F740 working without any problems. As to how to test the tape drives; no idea. `Check with your vendor'?

Hello Dave, Is it possible that a single ended SCSI drive and terminator were plugged into the differential SCSI port?

DLT problems on F740s
by Dave Atkin 01 Sep '99

We are just in the process of replacing our two F230s with three F740s and it's all going well apart from the DLT drives. We bought two Quantum DLT7000 differential SCSI drives, but we can't get them to work. On startup the 740 hangs for a long time just after the memory test and the "Complete" message. We've tried each drive on two 740s and they both act the same. We used the cable and terminator supplied with drives. The 740s hang even with the drive powered off. We've tried 5.2.2P1 and 5.3.2. Booting the diagnostic disk and running the scsi disgnostic tends to report SCSI errors of various types, eg "SCSI bus reset failed". Any ideas anyone? Could it be that these drives are not really differential - how could we tell? ------------------------------------------------------ Dave Atkin, Head of Technical Services Computing Service, University of York, YORK YO10 5DD Phone: +44-1904-433804 (ddi) Fax: +44-1904-433740 Email: D.Atkin(a)york.ac.uk ------------------------------------------------------

This means: in takeover mode, have the local "eta" interface takeover for the partner "eta" interface. > Then I came up with another enlightened idea "ifconfig eta -partner > 10.10.10.11" that does not do what "ifconfig eta partner 10.10.10.11" did > in the past (Oh, BTW, thanks NetApp for changing the syntax of the > command between revs). "partner" and "-partner" mean different things. "partner" specifies the takeover interface mapping; the argument after the "partner" keyword specifies the interface that should be taken over. "-partner" clears such a mapping, and takes no argument. These keywords were introduced in 5.2; we haven't changed the meaning of them since. "ifconfig" consumes its arguments one at a time, processing a keyword (and arguments, if applicable) and progressing on to the next keyword. Thus, when you specified "ifconfig eta -partner 10.10.10.11", "ifconfig" parsed it as follows: ifconfig eta -partner # clear the eta partner mapping ifconfig eta 10.10.10.11 # set eta's address Granted, this is somewhat counter-intuitive. > I should add that I tried "ifconfig eta partner 10.10.10.11" before only > to receive this error: > ifconfig: 10.10.10.11: bad vif partner address This is a very poor error message which will be fixed in an upcoming release. Partner mapping for vifs and ATM must be specified by interface name only; partner mapping for other interfaces can be specified by IP address or interface name. The error message is trying to tell you, in a round-about way, that you've specified a IP address, not an interface name. Thanks for your feedback; please don't hesitate to bring other such issues to our attention. Sam
