snapmirror question
by Alexander Schalek 21 Aug '07

21 Aug '07

Hi, I have a short snapmirror question for the experts... I try to set up a qtree snapmirror where the source is a snapshot (-s option) I couldn't find any example with a snapshot as source and every syntax I tried failed. The source should be a snapshot named snapshot.latest on volume testvol1. what I tried: snapmirror initialize -s snapshot.latest -S 3020:vol/testvol1/source_qtree 270:vol/testvol2/dest_qtree can someone please post an example with a snapshout as source... thanks a lot! cheers, alex

Bugs Online behavior/enhancement/bug
by Todd C. Merrill 21 Aug '07

21 Aug '07

So, I've been working with our SE's on trying to pick a new release to which to upgrade. I've also been doing my own research with the Bugs Online part of the NOW site. I either haven't figured out how it works, or the feature doesn't exist. If someone could tell me which one... :) Starting at the Release Comparison Tool: http://now.netapp.com/NOW/cgi-bin/relcmp.on I click on one release and enter another (not on the pre-determined list). I leave "fixes" set (I assume this means "bugs") and choose the checkbox "Filter Bugs to list of watched bugs." Then I click "go." The result I get back is what confuses me. It only shows me 8 bugs. There are 47 bugs on my watch list. What about the other 39 bugs? Do I assume they are fixed in both releases (dangerous!)? Or, was there no state change of that bug in both releases (e.g., it is still *not* fixed in both releases)? It's ambiguous. I really want to know the state of all my watched bugs in both these releases. Feature enhancement request: The ability to get a table of my watched bugs for more than two releases. Bug report (?): After getting the abovementioned list of 8 bugs, if I click the "arrow" icon to sort by severity, it will show me ALL the bugs in those releases (more than 8, more than 47... more like a few hundred), not just the pre-filtered ones (that checkbox is still checked when I click the sort arrow). I would expect it to sort only what is shown. Until next time...

Change UNIX security to NTFS - ACLs?
by Roy McMorran 14 Aug '07

14 Aug '07

Hello all, I have a qtree that I wish to change from UNIX security style to NTFS. Experimenting on a test volume I've found that when I make the change the ownerships of all the objects are preserved*, and appropriate ACLs show up for the owners. However, Unix "group" and "other" privileges do not seem to get translated to ACLs. Before I can proceed I really need to find a way to duplicate the group-based permissions that existed on the Unix side. I've started hacking together a script using smbcacls (the ACL utility in Samba). The idea is to set appropriate ACLs for specific groups and "Everyone" based on what the Unix mode bits used to be. Still I wonder if there's an easier way. Has anyone had a similar "challenge"? *In our environment all Unix and Windows user IDs are identical. We use an LDAP back end for Unix authentication and for our Samba-based domain controller. This is 7.2.1.1 on a FAS3020 in case it matters. Thanks for any input. -- Roy McMorran Systems Administrator MDI Biological Laboratory mcmorran(a)mdibl.org

On ONTAP versions 7 that's menu choice 4. How well does this erase the contents? Is it all overwritten? How often? Or is it just a reformat of some kind that only rewrites the meta data?

I've never understood that logic: If the disk is fully wiped, and "Safe Enough" to consider the data unrecoverable, then why restrict what you can do on that filer. You could always move the disk elsewhere (another filer, or a PC, or whatever) if you really wanted to try to get stuff back from it. Davin.

Increasing the size of disks in an existing array
by Bryano 10 Aug '07

10 Aug '07

Hi, I have 'inherited' several filers including FAS 270's and FAS 940's which only have 72GB drives and we are now running very low on spares and the company I work for is reluctant to buy another shelf, it has therefore it has been proposed that we remove a disk at a time from a volumes raid group and replace it with a larger drive (300GB) and then once the raid has recovered then remove the next disk and repeat the procedure until all the disks in the volumes raid raid group have been replaced with larger ones. My initial question is - is this possible and if so once all the drives in a particular raid group that makes up a volume have been replaced with larger ones will that show immediately as free space available in that volume or will we need to do something else to get the filer to see the additional free space?

snmp traps down/up-events
by Willeke, Jochen 09 Aug '07

09 Aug '07

Hi toasters, i have a strange issue which i was not aware of right now. We had a reboot of one of our nearstores these days and i recognized within our monitoringtool that we had only two events for the system: 1. system cold start 2. appliances is overall status changed to critical Plus is got an e-mail from the system saying REBBOT but this was too a few seconds after the "System Cold start" . But the suprising fact about that is, that we first got the cold start and then the critical event. Shouldn't it be the other way round?!?! I am open for any ideas about that :D Best Regards and thanks in advance Jochen

Right, but if you do that, you have to put all of non-qtreed data into a qtree on the destination. You can't do <dest_file>:/vol/<vol_name>/- as the destination. It won't work. You have to specify an actual qtree as the destination which means your data won't be in the root of the volume on the destination.

You can have more that one shelf on the 270, so you might want to buy a cheap second hand shelf from zerowait, and attach that to the existing filer, migrate the data. Not too hard to do. I've purchased 2 shelves and disks from zerowait in the past and never had any problems. cheers Matt -----Original Message----- From: owner-toasters(a)mathworks.com <owner-toasters(a)mathworks.com> To: Bryano <tgbryano(a)gmail.com>; toasters(a)mathworks.com <toasters(a)mathworks.com> Sent: Wed Aug 08 20:30:20 2007 Subject: Re: Increasing the size of disks in an existing array The 300G disk will be right-sized to the usable space of a 72G disk (68G?) and the extra space from the larger disk will be lost/unusable. http://now.netapp.com/NOW/cgi-bin/bol?Type=Detail&Display=164167 Do you have a shelf of 300G disks or were you just planning on buying a set of 300G disks to migrate into the shelf enclosure that the 72G disks are in? If you have a shelf of 300G disks, attach it with a new loop and snapmirror or ndmpcopy migrate the data to the new shelf. Then detach the 72G shelf. Of course that is trickier with the 270's since the head IS a shelf.

You might be right....i have heard that too, but never tried.

I'm almost sure I saw something in a Netapp Knowledgebase a while back saying that if you replaced the parity disks with larger disks you could add disks up to the size of the parity disks in a raidgroup and not loose space. -----Original Message----- From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com] On Behalf Of Willeke, Jochen Sent: Tuesday, 7 August 2007 6:20 PM To: Josef Radinger; toasters(a)mathworks.com Subject: RE: moving disks from one shelf to another Hi Josef, to you questions: 1) yes it is possible to mix...BUT if you have different sized disks in one raid-group the bigger disk will only serve the space of the smaller onces.

Mac OS AFP support?
by Daniel Brown 07 Aug '07

07 Aug '07

I've read TR 3472 "Integrating Mac(r) OS and NetApp Storage<http://www.netapp.com/library/tr/3472.pdf>" http://www.netapp.com/library/tr/3472.pdf and am aware of Thursby Software's DAVE: http://www.thursby.com/products/dave.html, which is of course >$100/seat, depending on number of seats purchased. I would like to know if there is any plans to support AFP natively in Ontap? Has anyone found any other solution to allow for multiplatform (for example PC's and Macs) use of the filer without having to worry about the data fork/resource fork issues? Yes, the macs can talk both CIFS and NFS, the problem is that all files touched by the macs look like this: -rw-r--r-- 1 501 foo 82 Jun 6 16:55 ._NTAP AAPL3472.pdf -rw-r--r-- 1 501 foo 699229 Jun 1 15:45 NTAP AAPL3472.pdf

moving disks from one shelf to another
by Josef Radinger 07 Aug '07

07 Aug '07

Hi, We have the following situation: A 3020c with 3 FC shelves (with 144G disks), and 2 SATA shelves. one head has the FC ones, the other ownes the SATA ones. For some reason 2 of the FC shelves are only half-filled and we would like to buy larger FC disks. *) is it possible to intermix different sized disks in one aggregate? (i think so) *) is it possible to intermix different sized disks in one shelf? eg. 7 144G disks and 7 larger disks in one shelf. i dont think so, without loosing the extra space. at least in the past this was not possible with older versions of ontap, if i read the older posts correctly. *) is it possible to move 7 disks from one shelf to the other half-filled shelf without data loss and interruption? then i would have 2 full shelves and one empty shelf and could ad the new disks to that empty shelf (and the same aggregate). yours josef -- MfG Josef Radinger it-services Medizinische Universitaet Innsbruck

Using Subinacl for CIFS ACL changes
by Jimmy Corncrake 03 Aug '07

03 Aug '07

Hi, We are attempting to make alterations to our file and directory ACLs using the microsoft utility Subinacl.exe. All attempts to use this utility under an account which has anything less than Administrative status on the Filer fail. For example running the following command subinacl /subdirectories \\sharesfiler\adm$ <file://sharesfiler/adm$> /display - with an account which has Power User & Backup Operator group membership on the Filer returns an error message - CreateFile Error : 1314 A required privilege is not held by the client. The account the command is being run under has both Full Control on the share and the ACL. If we use other MS utilities to perform the same function such as cacls, xcalcs or the windows GUI we can view and alter all ACLs without the need to grant the account Administative status. This implies that the access permissions are sufficient and therefore there is something subinacl is doing that is different to other tools designed for the same purpose. Upgrading the account priveleges to Administrator overcomes this problem but this is not an option except in our test environment. This behaviour is consistant on Ontap 6.5.7, 7.0.5, 7.0.6 and 7.2.2 implying that its not a release bug. Has anyone else come across this behaviour before or have any idea what subinacl is doing that the other tools do not? Your assistance will be appreciated. rgds, Oisin
