RE: BudTool transition news
by Cormier, Darleen 07 Apr '01

07 Apr '01

To Marion and any other Budtool users on this list. NetApp received this offical notification from Legato just this week, on the new migration policy. As we understand it Marion, it is available now. -----Original Message----- From: Marion Hakanson [mailto:hakanson@cse.ogi.edu] Sent: Friday, April 06, 2001 6:30 PM To: toasters(a)mathworks.com Subject: BudTool transition news Folks, Dunno if it's top secret, or what, but this week I innocently (hah!) asked Legato about transferring my BudTool license to a new NetApp that may be coming in soon. Their website says host transfers are free, so what the heck? Anyway, instead of getting an answer, I got directed to my local Legato salesperson, who informed me that they've finally come to their senses and are offering a one-for-one exchange to replace our BudTool products with equivalent NetWorker products, at no cost other than putting it all back on tech-support contract. I checked, and it's not 1-April-2001. Maybe by the Mayan calendar? By my investigation so far, NetWorker-6.1 claims it will do everything our BudTool-4.6.1 does, with the exception of: (1) NDMP backup to non-NetApp tape drive. An extra-cost SnapImage option turns your Networker tape host into an NDMP tape server to provide this functionality. OK, so it's not quite 1-for-1. (2) Cloning NDMP tapes. They say that'll be along soon (I forgot to ask if I could do that with SnapImage). But one can do a second backup to offsite media to partially work around this limitation. I'm still not wild about Networker, but "Free is a very good price." Well, not counting the initial $30k investment in BudTool, anyway. So, has anyone else heard about this? I could find no mention of it (nor any previous transition programs) on their website. Regards, -- Marion Hakanson <hakanson(a)cse.ogi.edu> CSE Computing Facilities

RE: Data Copy from Filer to Filer
by Knight, Graham 06 Apr '01

Hi Jessica, ndmpcopy is a great way to go. There are compiled versions on the NOW site, and the source code is on the ndmp.org site. ndmpcopy starts a dump on one filer and pipes it directly to a restore on another filer (or the same filer). It can be done on a directory level. It will preserve all of your unix permissions and NT ACL's when making the copy. It is also a much faster way to transfer data because there is no intermediate machine involved in the transfer. Yes, volcopy will only copy entire volumes.

RE: Windows, free space displays, gah
by Tom "Mad Dog" Yergeau 06 Apr '01

NetApp has an unsupported perl script that you can run as a cron job that will scan for users near their quotas and alert them to the fact. You can download the script from the NOW site. http://now.netapp.com/NOW/download/tools/disk_usage/ Another option is to upgrade to ONTAP 6.1, which supports quotas for Windows users based on SIDs. Also, I'm told that when you use the Windows quota feature, the amount of free space available to the user appears to be the amount of their quota that is free. Sounds like just what you need. :-) Tom -----Original Message----- From: Mike Knell [mailto:mike.knell@cs.tcd.ie] Sent: Friday, April 06, 2001 7:24 AM To: toasters(a)mathworks.com Subject: Windows, free space displays, gah Mornin' all, I'm besieged by Windows users complaining about not being able to find out what the state of this mysterious "quota" thing is, and complaining about files going missing because they've gone over quota, and _naturally_ this is all the fault of our filer rather than of either the users themselves for not keeping an eye on how much disk they're using, or Windows applications for not handling write failures gracefully.

RE: Inodes a go go
by Tom "Mad Dog" Yergeau 06 Apr '01

06 Apr '01

Okay, now I am really really confused. Here's a summary of my understanding; maybe someone can point out where I'm off track. 1. WAFL blocks are 4 KB 2. Max # of inodes is one per 4 K block 3. Each directory, even an empty one, fills at least one block 4. But, up to 128 empty directories can be sqeezed into one block So based on 3, I will run out of room before running out of inodes, but based on 4, I will run out of inodes before running out of room. (Maybe the problem is I don't understand was a dirent is?) Slightly off topic, can anyone suggest possibly a different, non-NetApp storage/file system that will give me a lot more inodes than I can get out of a filer? (Sorry Greg, but I need the best platform to meet the needs of the application, which might or might not be NetApp, so I have to ask.) The IO demands of this application are quite low, but storage and inode requirements are high. So any solution needs to be able to store large amounts of data and provide massive quantities of inodes, but doesn't need to be as fast as a filer. Thanks, Tom

RE: performance question ablout oracle on F840 filer
by Yarmas, Tom 05 Apr '01

05 Apr '01

Several people have made some good suggestions, and I would advise you look at the white papers on the Netapp site as well. One thing that will improve things for Solaris in particular is to specify DISK_ASYNC_IO=false in the Oracle parameter file (init.ora). Solaris will not do async i/o correctly, and each async i/o request will take extra time. When you do this, you may want to use multiple DB writer processes. Finally, how are you loading the data? If you are using SQL*Loader, it may be that the SQL is slowing you down. Direct path loading should show a dramatic change if you are not using it already. Just an FYI, it is generally going to be counter productive to have table and index data on different volumes oin the Filer. Because of the way the Filer does I/O to the disks, it generally does not help to seperate things that way. By having more drives in a volume, performance will improve. Although it sounds like your problem is just getting the data out of the Oracle engine and to the Filer (hence the direct path loading should help that). -tom

Agreed. You can't want more than 1 inode per 4K WAFL block, right? This application generates reports by generating directories. Each report can generate hundreds of directories on the filer. I don't know why it works this way but I'm told changing it will be quite a headache. So, all these directories take up lots and lots of inodes, but no real space on the filer.

What are the contents of these inodes? One would normally expect every inode to have at least one 4K block of data associated with it unless 1. It is a regular file with length <= 64 bytes (fits in the inode). 2. It is a symbolic link with length <= 64 bytes (ditto). 3. It is a device, or socket, or named pipe, or some other implictly zero-length object. That is presumably the rationale behind NetApp's "you can't possibly want more than 1 inode per 4 KB of data, can you?" upper limit.

We just upgraded all of our mirror filers (630's and 760's) to v6.1 and one of our development (760) filers to v6.1 and have seen no problems in the past few weeks (knock wood). The more nice features that are added it seems the more I want, for instance SnapMirror now states Transferring (0% complete, 100MB done), but what would really help is knowing how much needs to transfer and an estimation on how long it will take at the current rate. Overall, it is a big step forward from the 5.x days, and I must admit working with Network Appliance Filers is actually fun!

It appears to work extreemly well and I ahve had no problems so far... ...it has some neat little features, and the dismounting of volumes without a reboot makes things a lot easier. Anyone else gone to 6.1 yet ? If so, had any problems at all ? Jason Palmer WorldCom Server Engineering and Design Group

single mode trunc with a direct connection to unix host
by luis santos 04 Apr '01

Good day folks, we have ordered an F740 that we will be attaching to a M80 IBM aix host. with the Filer /unix host connection, we are planning to use a GB ethernet and 100 mbps ether card, with the 100 mbps card as the backup. We are exploring the possiblity of using a single mode trunk virtual interface. we are going to hook up the filer and the host direct with out the use of a switch and this will be a local dedicated network between the filer and the host. has anybody used a similar configuration and got it to work. the problem is that the IBM host has to be able to figure out which connection it will be talking to the filer and switch to the secondary if the primary fails. we will set the ether GB card as the favored path. regards, Luis Santos Loblaws Co.
