6.0.1R1 Filerview -- How to print
by Darragh, Stephen J 17 Jan '01

17 Jan '01

I hope this is one of those questions that I will say "of course, why didn't I see that". 6.0.1R1 filerview running from netscape 4.7.5 on a sun solaris 8 system. There are now a great number of reports and disk information, but I can't see how to print them. There is no CTRL-P, or alt-click to bring up a print option. I could use xwd, but there must be a simple way that I am just missing. Thanks in advance... Stephen Darragh

ENTERPRISE EMAIL
by Joe Luchtenberg 17 Jan '01

17 Jan '01

There are a number of good threads in the toasters archives touching on large-scale e-mail implementation. My question is what other sites/newsgroups would you suggest are good primary resources for information/threads on enterprise e-mail? (I already have the Earthlink whitepaper from an earlier toasters thread) FWIW, the particular implementation under consideration is open to most anything at this time -- Exchange, sendmail, web-based, POP, etc. TIA.

Multicast support in ONTAP?
by Brian L. Brush 17 Jan '01

17 Jan '01

I'm experimenting with back-to-back (crossover) links between Sun boxes and filers. Specifically, I'm trying to use Solaris 8's IP network multipathing failover and fallback with such connections. The problem is that Solaris is unable to recognize the failure of a NIC directly connected to a filer. In testing, the feature works as expected on our normal switched network. Solaris's IP network multipathing failover and fallback (what a mouthful!) works by initially sending multicast ICMP echo requests (to ALL-SYSTEMS.MCAST.net). The Solaris box relies on routers and hosts to respond to the multicast requests. Then it sends periodic unicast ICMP echo requests to those specific routers/hosts and knows a NIC has failed when the responses stop. Snoop on the Solaris box reveals the filer is not responding to the multicast requests. The Solaris box, therefore, never even begins its monitoring because it thinks there is nothing to ping. Here is an excerpt: 192.168.0.5 -> ALL-SYSTEMS.MCAST.net ICMP Echo request (ID: 8194 Sequence number: 1) 192.168.0.5 -> ALL-SYSTEMS.MCAST.net ICMP Echo request (ID: 8194 Sequence number: 1) 192.168.0.5 -> ALL-SYSTEMS.MCAST.net ICMP Echo request (ID: 8194 Sequence number: 1) The filer is definitely sitting on the other end of the cable: ping -s 192.168.0.1 PING 192.168.0.1: 56 data bytes 64 bytes from 192.168.0.1: icmp_seq=0. time=1. ms 64 bytes from 192.168.0.1: icmp_seq=1. time=0. ms 64 bytes from 192.168.0.1: icmp_seq=2. time=0. ms 64 bytes from 192.168.0.1: icmp_seq=3. time=0. ms Solaris box is an Ultra 1 with Solaris 8 10/00. Filer is an F760 running Data ONTAP 5.3.7. We've tested Sun ge to NetApp gigabit and also Sun hme to NetApp quad fast ethernet. I'm interested in hearing any suggestions that might make this configuration work. --Brian L. Brush Senior Systems Administrator Paradyne Corporation

That's one of the (few) beauties of NIS -- you don't have to go around telling everything that a map has changed. I've never gone machine-to-machine running automount(1) to kick it in the pants just because we changed the password or auto_home map. The _worst_ is that ncsd caches something and we need to kill and restart it.

There are two types of automount maps (direct and indirect). I believe that direct maps are the ones that need to be signaled when a map changes. We have had to use direct maps for nested filesystem mounts, but do this only on an exception basis. See the O'Reilly book "Managing NFS and NIS" by Hal Stern.

inode limitation?
by Magnus Thorne 16 Jan '01

16 Jan '01

Greetings, I'm planning on using a NetApp 760 to store *many* small files. However, I'm getting vague answers from NetApp for my problem, so I figure I'd ask here. NetApp has told me that they don't recommend that I have more than 250,000 inodes per volume. Is this a real limitation, because my NetApps currently have 6.1 million inodes available? The online documentation says I only need to add more hard drives to get more inodes (1 per 32K). Has anyone used the netapp for small files? Small means millions of < 60K. Also, I need all these files available on one share. Also, what should I look out for? I know to disable the read ahead cache. I plan to not use snapshots. thanx, -Mag

Basically, if it's indirect map, as auto_home, you don't need to kick "automount" on every client, but if it's direct map - you have to. -----Original Message----- From: Jeffrey Krueger [mailto:jkrueger@qualcomm.com] Sent: Monday, January 15, 2001 12:38 PM To: Rainchik, Aleksandr (MED, Non GE) Cc: 'Jeffrey Krueger '; 'toasters(a)mathworks.com ' Subject: Re: /home layout with many filers and NIS automount On Sat, Jan 13, 2001 at 03:16:20PM -0600, Rainchik, Aleksandr (MED, Non GE) wrote: > > There is another thing against > > #auto_home NIS map > > user1 filer2:/vol/vol1/& > design.

Are you sure you're not confusing this with "per directory" ? Even though WAFL is fairly efficient when it comes to large directories, there are limits to what you would want to experience.. > Is this a real limitation, because my NetApps currently > have 6.1 million inodes available? Neo, it's not. This is a 760: df Filesystem kbytes used avail capacity Mounted on /vol/vol0/ 343184120 265805356 77378764 77% /vol/vol0/ df -i Filesystem iused ifree %iused Mounted on /vol/vol0/ 13987164 6012814 70% /vol/vol0/ And it's running just fine (mailspool with one file per message) > The online documentation says I only > need to add more hard drives to get more inodes (1 per 32K).

I'm not sure that would help a lot with small files - this is more of a win wit large files (or possible very slow clients) > I plan to not use snapshots. Whether or not to use snapshots is more a question of the change rate in your data set than the number of files - the 760 shown above is running with readahead set, and snapshots. No problems whatsoever. Regards, -- ---Ketil Kirkerud Elgethun, Infostream ASP

Jim, The website I fix uses very small files to handle details of customer events so they can be billed. One file per event. I'm not saying this is a good design. <chuckle> smith> maxfiles spool Volume spool: maximum number of files is currently 8258829 (1428275 used). smith> df -i /vol/spool Filesystem iused ifree %iused Mounted on /vol/spool/ 1428275 6830554 17% /vol/spool/ smith> df /vol/spool Filesystem kbytes used avail capacity Mounted on /vol/spool/ 46944924 14936040 32008884 32% /vol/spool/ /vol/spool/.snapshot 0 7834048 0 ---% /vol/spool/.snapshot smith> How come it's not "maxfiles /vol/spool" -- different coders?

The training I received from NetApp personnel indicated that a particular strength of WAFL is the ability to add more inodes on the fly. There wasn't any mention of any particular recommended limit. A quick check of my system shows that even my smallest volumes currently have "Maximum Numer of Files" set over 1 million. On a 760, one volume with 330 GB of data space, 13 million on MAX files, 550 thousand currently. Another with 150 GB of data space, 6 million on MAX files, 414 thousand currently. As far as I know, no one at our site purposely expanded any of the MAX settings. ===== Jim VandeVegt vandevegt(a)yahoo.com vandevegt(a)avaya.com http://members.xoom.com/vandevegt Toilet paper should come off the front! __________________________________________________ Do You Yahoo!?
