RE: Veritas Netbackup Database
by Strange, John 25 Oct '01

25 Oct '01

Hmm, I would say that file locking has improved, if you want to test that setup a mail server on the NFS mount and generate a lot of emails, or database of some type to test it. Where I would be concerned would be in the middle of the back to have a network problem and end up trashing the backup database. I would really be hard pressed to use NFS to store the backup database. If you plan on doing it make sure you are forcing sync on your NFS mount also as NFS v2 usually defaults to async writes. Which could cause a consistency problem if you suffer a network outage. Also another concern would be that your backup would probably fail if you hang the NFS mount as most *NIX boxes hate when you lose network connectivity across an active NFS mount. - John -----Original Message----- From: Manny Kaiser [mailto:mkaiser@mmcnet.com] Sent: Thursday, October 25, 2001 3:28 AM To: Jon Walton Cc: toasters@mathworks. com Subject: RE: Veritas Netbackup Database I was under the distinct impression that file locking in NFS in today's operating systems is considerably more reliable then it was years ago. I have never encountered a problem with any application running on an NFS mounted file system. I am under the impression that the quote below is something that was copied out of earlier versions of the manual and never reviewed again. When using NFS you might suffer a performance penalty if your systems are not correctly configured. -----Original Message----- From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com]On Behalf Of Jon Walton Sent: Wednesday, October 24, 2001 11:31 PM To: Jeff Kennedy Cc: toasters@mathworks. com Subject: RE: Veritas Netbackup Database Now that I look, the 3.4 DataCenter install guide states: "Because the product uses file locking, VERITAS recommends that you not install NetBackup in an NFS mounted directory.

carrierscan
by Tim Longo 25 Oct '01

25 Oct '01

Greetings: I am preparing to install Symantec CarrierScan, and came across something in the manual I have a question about. There is a statement in the manual that says "Virus scanning should be disabled before initiating backup of the NetApp Filer". It seems to me that this may not apply if ndmp were being used for backup? Anyone else have experience with this issue? Thanks, Tim

Ndmpcopy - inconsistent dumpmap
by Dawn Lovell 25 Oct '01

25 Oct '01

Thanks to everyone who replied to my question regarding ndmpcopy versus vol copy when migrating from a F740 to a F820! Based on the recommendations, we've done a level 0 ndmpcopy and two increasing incrementals (level 1 and level 2). On what was to be our last incremental (level 3) with the source filesystem read-only, we received the following message: newfiler: LOG: RESTORE: newfiler: LOG: Inconsistent dumpmap on inode 10831660. The copy goes on to complete successfully, but I'm concerned about the impact of this. I'm running a find to try to locate the file or directory with that inode, but it's going to run forever with the number of files we have. Is there a faster way than find to match the inode to a file? Does anyone know if this is a serious error? I'd thought that it was probably the result of a file on the target filesystem being changed outside of the ndmpcopy process. That shouldn't have happened, but it's certainly possible. I called NetApp support about this, however, and was told that it was a filesystem problem on the target filer and that we should bring it down and run wafl_check. I can't find the error in the archives or on the NOW site, so I would greatly appreciate any insight. Thanks for your time! Dawn Lovell dlovell(a)centurytel.net

Deleting data
by Benny Wiström 25 Oct '01

25 Oct '01

Hi! I have copied approximately 70Gb from one volume to another. Now I want to delete the data from the original volume. Is is possible to do this without having the data end up in the snapshots and filling up the volume? I would prefer if this could be done without having to delete any snapshots since it still is other data on the volume. -- Regards: Benny Wiström CSC Phone: +46 13 4653647 Systemadministrator 581 88 Linköping Fax: +46 13 185771 Benny.Wistrom(a)consultant.saab.se Sweden Mobile: +46 13 4653647 Sometimes I think the surest sign that intelligent life exists elsewhere in the universe is that none of it has tried to contact us. -Calvin & Hobbes (Bill Watterson)

RE: View Security Log from W2K Client

I would like to be able to scan my security logs on our netapps for unauthorized access. Most of the products I have looked at only work on NT servers, and will not work on our filers.

I believe they do not support this due the fact that operations on the database files involve file locking. That is what is remember reading in the Unix Admin Guide.
