Dual-domain CIFS
by Nils Vogels 30 May '07

30 May '07

Hi, In a cluster, since there are two heads, it is possible to make each head member of a different domain for CIFS. Will this cause problems during failover?

R200 AT-FC2/FCX
by Carl Howell 30 May '07

30 May '07

We currently have an R200 with six AT-FC2 shelves. We want to add three AT-FCX shelves. Currently, we only have two loops and the AT-FC2's are spread across both of them. Should I move all of the AT-FC2's onto one loop and put the AT-FCX shelves on the other loop or just add the AT-FCX's to the current loops? Thanks, --Carl

Re: ndmpcopy for Linux

Hi, I was able to build it on RHEL4, running kernel 2.6.9-42.EL. Grab the bits from here: http://www.ndmp.org/download/ndmpcopy The mods I made to get it to build were only in 2 files: ./src/Makefile 37c37 < LIBS = -L$(LIBDIR) -lndmp -lsocket -lnsl --- > #LIBS = -L$(LIBDIR) -lndmp -lsocket -lnsl 39c39 < #LIBS = -L$(LIBDIR) -lndmp --- > LIBS = -L$(LIBDIR) -lndmp ./lib/ndmp_common.h 40c40 < #define XDR_AND_SIZE(func) (bool_t(*)(XDR*, ...))xdr_##func##,sizeof(func) --- > #define XDR_AND_SIZE(func) (bool_t(*)(XDR*, ...))xdr_##func ,sizeof(func) I did not run any exhaustive tests after I built it, but hopefully this will at least get you started.

Max number of LUNs
by Robert Lazzurs 27 May '07

27 May '07

Hello, In relation to the recent threads on max inodes and max dir size I was wondering if anyone has any experience with the limit on the number of LUNs in a filer? Kind regards,

I presume this is one of the features coming out in the new 10.1 release?

RE: SnapDrive install with existing iSCSI LUNS
by Julio Calderon 24 May '07

If you want to test your procedure before you actually do it!! I would create a dummy lun and mount the same way dump some data in it, make sure you format the same type of file system.... Remove and try sd.... That wil raise your comfort level... My personal best practice is to try it, back it up, test restore and then do your live work....

I'd say disconnecting the LUN, removing all traces in the iSCSI initiator, then installing SnapDrive, and then using SnapDrive to 'connect' to the LUN is the right way. If I were you, I'd test this using an ONTAP simulator, though ;) Grtz, Nils -- Simple guidelines to happiness: Work like you don't need the money, Love like your heart has never been broken and Dance like no one can see you.

SnapDrive install with existing iSCSI LUNS
by Sean McWherter 24 May '07

24 May '07

I need guidance in setting up SnapDrive on our Windows 2003 Enterprise x64 servers. We have two of these servers clustered hosting our SQL 2000 servers. My question is this: What is the proper way to install snapdrive on a machine that already has LUNs mapped with the iSCSI initiator? Should I disconnect the LUN first? I did read one post on the NOW forums where a guy got hosed by disconnecting the LUN and then installing SnapDrive after someone told him that's what to do. He was never able to mount them back. I'm trying to dot all my I's and cross all my T's before I dive in here.

rysnc and filers
by tmac 24 May '07

24 May '07

Okay, I am trying to copy data from a DOT-7 to a DOT-GX. I start off with: mount filer7:/vol/src /src mount filerg:/ /gx I then do (from RHEL4U2): cp -a /src/dir1 /gx I then do: rsyn -avH --delete /src/dir1/ /gx/dir1/ There is nothing changing on the source, yet it transfers files anyway. Anyone have a clue as to why? The destination get some files marked with current time, yet others are marked with an older time. -- --tmac RedHat Certified Engineer #804006984323821 Principal Consultant, RABA Technologies 240-373-3926 (office) 301-688-4705 (Lab) 214-279-3926 (eFAX)

Or rsync --whole-file the first time, or ndmpcopy. ----- Original Message ---- From: Nils Vogels <bacardicoke(a)gmail.com> To: tmac <tmacmd(a)gmail.com> Cc: toasters(a)mathworks.com Sent: Wednesday, May 23, 2007 3:59:21 PM Subject: Re: rysnc and filers Hi tmac, On 5/23/07, tmac <tmacmd(a)gmail.com> wrote: > Okay, I am trying to copy data from a DOT-7 to a DOT-GX. > ... > > I then do (from RHEL4U2): > > cp -a /src/dir1 /gx > > I then do: > > rsyn -avH --delete /src/dir1/ /gx/dir1/ > > There is nothing changing on the source, yet it transfers files anyway. > > Anyone have a clue as to why? cp doesnt take all metadata.

A-SIS (Netapp DeDupe)
by Glenn Dekhayser 23 May '07

23 May '07

Doing some reading on the A-SIS feature. Will this only De-Dupe WITHIN a flexvol, or leverage 4kb block commonalities within an aggregate? I would think the savings would be dramatic across flexvols, especially in Boot-SAN environments. Glenn (the other one)
