benchmarks
by Steve Sapovits 12 Jul '01

12 Jul '01

I'm looking for any benchmarking info. related using a NetApp instead of server-dedicated disk in a web server cluster; i.e., how many web servers can I run before a single NetApp device becomes slower than using dedicated disk per server? The more specific the benchmarks, the better (relating to types/versions of servers, OS, etc.). ---- Steve Sapovits

RE: Deleting data on NetApp.
by Fox, Adam 12 Jul '01

12 Jul '01

This comes up quite a bit. It all depends on who how sophisticated you think the person is who may be trying to retrieve the data is. For 99.99% of the world, just zero'ing the disks (even multiple times if it makes you feel comfortable) is enough. I suppose you could create some dummy data to put on the disks after you zero out the disks, then zero them out again. But that's a lot of time and effort to get you from 99.99% to 99.999%. If you are concerned about professional, government-backed efforts to recover the data, then your only real option is to destroy the disks entirely. Bust them into thousands of pieces and dispose of those pieces in different trash containers. While this is certainly expensive since you can't return or re-use the disks, it is by far the most secure. However, there are very few people who need this level of security, but it's an option if your data abosulutely cannot ever be recovered. Hope this helps. -- Adam Fox NetApp Professional Services, NC adamfox(a)netapp.com > -----Original Message----- > From: Israel, Meital [mailto:meital.israel@intel.com] > Sent: Monday, July 09, 2001 8:55 AM > To: NetApp Mailing List (E-mail) > Subject: Deleting data on NetApp. > > > Hi All, > > Does anyone know a utility to format the NetApp disks without > being able to > unformat it? > > Thanks, > ************************************** > Meital >

RE: ndmp problem legato & netapp

Jan, Legato backup software needs to save client (NetApp) "index" information back to Backup server host. Create same pool name on Backup host's attached tape drive. If you don't have tape drive attached to backup server. You can create file device and label it same as NetApp pool. Make sure you have patch 001 for 6.0.1 Legato Networker. Please collect savegrp output. savegrp -vvvv -G netapp_group_name Cheers, Chris -----Original Message----- From: Schepers, Jan [mailto:Jan.Schepers@atosorigin.com] Sent: Wednesday, July 11, 2001 5:12 AM To: toasters(a)mathworks.com Subject: ndmp problem legato & netapp Hello list, The following messages are generated by Legato, NetApp and NDMP backup.

Problem renaming files
by Frank Gilmurray 11 Jul '01

11 Jul '01

We have our CVS repository on a F840 running 6.1R1. I've been chasing (what I thought was) a CVS Commit problem re renaming files but now I think this may be a filer issue because I've been able to reproduce the problem outside of CVS. We're using FreeBSD. Basically I have group write permission to a directory where I want to rename a file. All attempts fail with a "Permission denied" error. Then I restored the directory from a tgz file and after that, everything started working fine! The owners, permissions, and modified dates were the same as before so I don't understand why restoring this directory would change anything. Previously we had our CVS repository on a F520 running 5.3.6 and we never had any problems. Please, can anyone explain this? Thanks much, Frank Here's the output: gilmurra:/sweng/CVS_BACKUP/src> ls -la total 452 drwxrwxr-x 2 1237 staff 8192 Jul 11 10:41 . drwxrwxr-x 22 1237 staff 8192 Jun 11 19:42 .. -r--r--r-- 1 141 staff 52845 Jun 11 19:12 ata-all.c,v -r--r--r-- 1 1237 staff 14819 Mar 26 19:26 ata-all.h,v -r--r--r-- 1 141 staff 14819 Jul 10 16:35 ata-all.h,v.old -r--r--r-- 1 gilmurra staff 14819 Mar 26 19:26 ata-all.h,v~ORIG -r--r--r-- 1 1237 staff 28550 Mar 26 19:26 ata-disk.c,v -r--r--r-- 1 1237 staff 4179 Mar 26 19:26 ata-disk.h,v -r--r--r-- 1 1237 staff 35634 Mar 26 19:26 ata-dma.c,v -r--r--r-- 1 1237 staff 16649 Mar 26 19:26 ata-raid.c,v -r--r--r-- 1 1237 staff 5170 Mar 26 19:26 ata-raid.h,v -rw-rw-r-- 1 gilmurra staff 67396 Jul 11 10:37 ata.tgz -r--r--r-- 1 1237 staff 21862 Mar 26 19:26 atapi-all.c,v -r--r--r-- 1 1237 staff 9893 Mar 26 19:26 atapi-all.h,v -r--r--r-- 1 1237 staff 48595 Mar 26 19:26 atapi-cd.c,v -r--r--r-- 1 1237 staff 12804 Mar 26 19:26 atapi-cd.h,v -r--r--r-- 1 1237 staff 12470 Mar 26 19:26 atapi-fd.c,v -r--r--r-- 1 1237 staff 3748 Mar 26 19:26 atapi-fd.h,v -r--r--r-- 1 1237 staff 18632 Mar 26 19:26 atapi-tape.c,v -r--r--r-- 1 1237 staff 7100 Mar 26 19:26 atapi-tape.h,v -r--r--r-- 1 gilmurra staff 14819 Jul 10 16:35 x gilmurra:/sweng/CVS_BACKUP/src> mv x ata-all.c,v override r--r--r-- 141/staff for ata-all.c,v?

what ndmp user account i can use to backup filer by legato networ ker 6.0
by Zhonghua-Dennis.Huang＠nokia.com 11 Jul '01

11 Jul '01

Hi all, Forgive me if I asked a naive question. I believe there should be a user who can access filer's ndmp service. But I can not see such configurations on filer's ndmp options, is any user on filer ok for ndmp backup use? And on Legato networker, where i can specify the ndmp port which supposed to be 10000? If someone has successful experience on Networker ndmp configuration to backup filer, pls help me. ************************************************************************ Huang Zhonghua-Dennis System Administrator,Product Creation Process IM Beijing Product Creation NOKIA(CHINA) INVESTMENT CO.LTD Nokia Mobile Phones Nokia Tower, Pacific Century Place 2A, Gong Ti Bei Lu, Chaoyang District Tel:+86-10-65392828 Ext.3450 Fax:+861065393825Mobile:+86-13910218853 E-mail:zhonghua-dennis@nokia.com <mailto:E-mail:zhonghua-dennis@nokia.com> ***********************************************************************

RE: du -s after ndmpcopy - why are the filesizes different?
by Melvin, Grant 11 Jul '01

11 Jul '01

Hi Simon, In addition to Adam's comments: > the restore making better use of blocks since > it gets to re-write your data from scratch, etc. Directories on the source won't reclaim space from old entries on deletion, but will be reclaimed using restore via NDMPcopy. You will also probably have a restore_symboltable file on the destination side that is required by restore when doing incrementals. Cheers, Grant -----Original Message----- From: Fox, Adam [mailto:Adam.Fox@netapp.com] Sent: Monday, July 09, 2001 8:05 AM To: 'Clawson, Simon'; 'toasters(a)mathworks.com' Subject: RE: du -s after ndmpcopy - why are the filesizes different? I guess my question is how different were the results? A couple of percentage different is normal in dump/restore situations, which ndmpcopy is. Things like the restore making better use of blocks since it gets to re-write your data from scratch, etc. As far as verifying ndmpcopy, remember that ndmpcopy is just a native ONTAP dump/restore so any method you would use to verify your backups would also apply here. Most of them are not fun like what has been suggested of comparing file by file. If you trust your backups, you should be able to trust ndmpcopy. -- Adam Fox NetApp Professional Services, NC adamfox(a)netapp.com > -----Original Message----- > From: Clawson, Simon [mailto:simon_clawson@mentorg.com] > Sent: Monday, July 09, 2001 8:11 AM > To: 'toasters(a)mathworks.com' > Subject: du -s after ndmpcopy - why are the filesizes different? > > > I ran an NDMP copy on my filer to take some qtrees from one volume to > another.

NetBackup with large Indexes.
by Mati Giladi 10 Jul '01

10 Jul '01

Hi, We use Veritas Netabackup 3.4 to backup - on Solaris platform - Netapp / EMC in our site. The index size is growing to over then 70 Gb tape capacity. As far as we know the DbBackup ( the command that backup the index ) doesn't know to backup more then one tape capacity. One of the solutions is to backup the index using ufsdump ( it works ) to more the one tape. Does someone have any solution for this problem using the official veritas tool ( or other ) ?
