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

Hi Jeff, I'm curious, what are the issues that stop you from using ndmpcopy?

However, if you have the problem I do which is wanting to copy specific data from one volume to another you use something like ndmpcopy. My particular case is special and ndmpcopy doesn't work for me either due to filesystem fragmentation so rsync is my only option. ~JK Jessica Fernandez wrote: > > What are your recommendations of copying data from one filer to > another? > > I have estimated time of 28 hours to transfer 70 GB via a copy command > on the host machine. > > I have tried to copy via CIFS accessing from NT servers using drag and > drop.

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.

I have estimated time of 28 hours to transfer 70 GB via a copy command on the host machine. I have tried to copy via CIFS accessing from NT servers using drag and drop. Encountered errors which halted the copy process due to files that were linked to incorrect locations. Unix files in the users desktop were linked to other machines and the path was invalid. Did a grep to locate these linked files in the user folders, and found too many to change one by one. The vol copy command is only useful when copying from volume to volume on the same filer, correct? I am looking for the most efficient way to move data. Any suggestions would be great!

If you have Snapmirror, that works very well. The other option I have found is to use ndmpcopy from a Unix host.

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. What they tend to do is point to the Windows (NT and 2000, btw) disk free display and say "Look! It says I've got 35GB of free space!" without working out that this is the free space on the entire volume rather than in their quota. What are peoples' views on providing state-of-quota information to Windows users? Ideally, the disk free display should show the state of their quota rather than the volume, but things just don't seem to work that way. We have a web page they can query their quotas from, but either that or the simple act of logging into a Sun and saying "quota -v" is considered to be rather complex and not pro-active enough..

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
