Here's the same for "du", which is even more annoying because there isn't a "-prune" option for du. Anyone at NetApp care to comment about whether the inode number for ".snapshot" is constant (and can be counted on)? It always appears to be inode 67. - Dan --- fileutils-3.16/src/du.c.orig Mon Feb 16 00:46:43 1998 +++ fileutils-3.16/src/du.c Mon Feb 16 00:56:35 1998 @@ -54,6 +54,10 @@ #include "save-cwd.h" #include "error.h" +#ifndef S_IRWXUGO +#define S_IRWXUGO (S_IRWXU|S_IRWXG|S_IRWXO) +#endif + #undef convert_blocks #define convert_blocks(b, size) (size == size_kilobytes ?

question about multi-RAID
by Daniel Quinlan 17 Feb '98

17 Feb '98

I have a new F630 with 4 shelves (2 pairs) or about 200GB of disk space. Ideally, I would like to configure it with two 100GB RAID groups composed of 12 data drives, one parity, and one spare each (maybe only one spare for the entire filer). If I remake the filesystem with half the disks and start using it, will I be able to upgrade to multi-RAID/multi-volume and add the other half of the disks without a backup/restore cycle? Is there anything else I should know about trying this? - Dan

Re: Multiple IP Addresses per interface?

From: Brian Tao <taob(a)nbc.netcom.ca> > > According to the man page: > > The interface name vh is used to specify IP virtual host > addresses associated with the filer. Only alias addresses (using > the alias option) may be assigned to the vh interface. > > So I can assign multiple IP's to vh... how do I bind those IP's to >a physical interface? Or is this only used for the virtual hosting >feature in the HTTP server? Unfortunately the doc on this subject doesn't really spell all this out in a manner that could be described as crystal clear, but... My understanding is that the vh interface is just associated with the HTTP daemon's virtual hosting feature. The addresses on vh are the ones that the web server runs through /etc/httpd.hostprefixes to locate a target specific home directory for inbound HTTP requests. However, there is of course the "little" issue of packets destined for a vh address being able to find their way into a filer in the first place, which will inevitably require some cooperation from the real, physical interfaces. This could conceivably be made to happen via routing trickery, perhaps using host routes to ensure that packets destined for vh addresses get fired at a filers physical interfaces on their last hop, or maybe even full network routes, where the vh addresses are on a subnet that is entirely internal to the filer and the physical interfaces form routes to that subnet. Failing this, then you're right, there needs to be some correlation between vh addresses and the addresses being supported by the physical interfaces. Alas I haven't been able to find a description of whether this is a manual or automatic process. I have to assume manual for now. My own experience starts and ends with loading up just the physical interfaces with addresses, and leaving the vh interface alone. Keith

NetApp 450 end of life
by Mark Richards 17 Feb '98

17 Feb '98

Hello We have a Netapp 450 (the 486 EISA-based machine). NetApp will soon discontinue support for the machine and I'm curious as to what others think of this. We bought our 450 in Nov. 1995 before the PCI-based filers appeared. We are a fairly small shop, (nothing like some of the huge servers discussed on this list :-), but we are delighted with our filer which has never crashed or given us any problems. I understand NetApp reasoning for desupporting the 450 - it costs money to test each new version of the OS on the EISA boxes for what I assume is a small number of remaining users. What do other successful vendors do with older hardware? Does the newest Solaris run on older Sparcs? What about CISCO? I have some seven year old Telebit netblazer routers and they still run the newest OS. NetApp compares its filers to routers, why can't they do what Telebit has been able to do? Our 450 is 27 months old....its performance is terrific for our purposes and I'd have a hard time forming a technical and business case to replace the system with a new model. I guess I just don't think 27 months is VERY OLD! What do you think? I'm not bashing NetApp, they're a great company, I'm just disappointed.

Exabyte Mammoth (exb-8900) and 220 changer support?
by Dave Cole 16 Feb '98

16 Feb '98

I am in the process of evaluating tape units and came upon the startling discovery that (as of at least) ontap 4.3R3, there is still no support for the Exabyte Mammoth tape drive. Does anyone know any details about this issue? I would really like to be able to recommend the Exabyte Mammoth 20/40GB tape drives. ------------------------------------------------------------- Dave Cole (DC1110) | dacole(a)netcom.ca Systems Administrator | dacole(a)vex.net | office/~dacole/ Netcom Canada | www.vex.net/~dacole/ 905 King Street West, Toronto, M6K 3G9 | phone - 416.341.5801 Toronto, Ontario, Canada, Earth, Sol | fax - 416.341.5725

Re: Multiple IP Addresses per interface?
by Keith Brown 16 Feb '98

>The purpose of this email is to ask if I can configure multiple IP >addresses per physical interface on an F330. Sure. It's very easy using the "alias" option to ifconfig(1). For example, the sequence: ifconfig e0 192.1.1.1 ifconfig e0 alias 192.1.1.2 will put a couple of addresses on the e0 interface. >If it is possible I did >not see reference to it in the manuals. It's described on the na_ifconfig(1) man page in the command reference guide for Data ONTAP 4.3.X. If you have a NOW account, you can obtain this electronically from: http://now.netapp.com/knowledge/docs/crq41.pdf >the filer is a F330 running 4.0.2c (?) and I have NFS over TCP turned off. Hmmm. I don't know offhand when the multiple IP addresses on a single interface support was formally introduced. There's a chance it was post 4.0.2c, although I'm not certain. If your na_ifconfig(1) man page doesn't mention the "alias" option, you may need to get a hold of a newer software release. Again, you can download that from the NOW web site if you have an account there. Keith

GNU find patch to fix .snapshot annoyance
by Daniel Quinlan 16 Feb '98

16 Feb '98

It's really annoying when find(1) descends into a .snapshot directory. Here's a patch against GNU findutils 4.1 tested under Linux and Solaris to fix the problem. It still allows descent into .snapshot, but only if .snapshot is specifically listed on the command line. GNU findutils is available at <URL:ftp://prep.ai.mit.edu/pub/gnu>.
