RE: Exports file

Most permissive permission always applies. So here, client will get RW from the "rw=-123.123.4.0/24" statement. ro will be dropped as client gets most permissive permission when conflict. Try it! You can also play with 'exportfs -c' (I think "-c" is the arg - give it a client name and it will show you what exported and how) Best regards, ~~~~~~~~~~~~~~~~ Kevin Parker Mobile: 919.606.8737 http://theparkerz.com <blocked::http://theparkerz.com/> ~~~~~~~~~~~~~~~~ _____ From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com] On Behalf Of Conner, Neil Sent: Thursday, May 08, 2008 6:28 PM To: Toasters Subject: Exports file I want configure an exports file to grant a client ro access when I've excluded the subnet the client belongs to from rw access.

Re: Max of 20MB/sec through FC attached LTO tape drive? Overland neo 2000

I have seen the minra option on the volume have a major affect on backup speed. Have you got it set to minra=on on any of your volumes?

Hey Folks, Bringing up 'minra' starts to tread into a performance issue. I highly recommend that a NetApp support case be opened to ensure that this is handled with the appropriate skillset, experience and attention.

I've seen for instance java going horribly wrong in that way. This is because when running the 'software install' / 'software upgrade' commands, you are sure the commands are run as the local admin on the filer (=root). When using CIFS to place/unpack the files, you usually are performing that action with the permissions of "whoever is currently running explorer.exe", which might be the cause of spending some extra after-office hours, and (most importantly) might cause you to miss dinner @ home. Actually, I don't quite understand why NetApp still uses this method in their upgrade advisors, IMHO, they have developed far better alternatives by now by way of the 'software *' commands.

SnapDrive for Windows & CIFS
by Milazzo Giacomo 08 May '08

08 May '08

Hi, this is a good question: must CIFS be licensed to use SnapDrive for Windows? I've never had the chance to perform some test but I think that the answer is "yes". And you know why: because SnapDrive for Windows needs to 'see' and 'reach' the volume where you create the LUN(s) by CIFS using a UNC path. It's also true that there a limited CIFS that permit to access to the administrative share C$ but, as example, when I've tried to upgrade a DataOntap using the windows package, without a full CIFS license, the unzip of data failed! So. Why customer ha sto spend money for an unused license if he needs only SAN functions. Regards
