Data Ontap NFS and "no root squash"
by Milazzo Giacomo 16 Nov '07

16 Nov '07

Hi all A customer using Linux is asking me how to have an export from a NetApp volume with option "no root squash". I've looked for it on NOW site with no luck The only thing I normally do is to export with anon id=0, rw to some hosts and root to others... Help Thanks in advance

Thought I'd share
by Glenn Dekhayser 15 Nov '07

15 Nov '07

Had an interesting issue over the weekend at a client, with a happy ending thanks to Netapp support. Client had two aggregates on a 980 controller, one with 144GB drives, one with 300gb drives - each aggr had 1 hot spare, running raid-dp. During the weekend raid scrub, one of the 144gb drives starts popping errors and goes into a predictive failure mode, so the diskcopy starts copying data to the hot 144gb spare. Halfway through this, the predictively bad drive actually fails hard- now it gets interesting. Rather than rebuild the rest of the 144gb hot spare from parity (since it already had much of the data), ontap decided it would abort this diskcopy and pick ANOTHER spare drive to rebuild to- of course the only one left was a 300GB drive, so it picked that one- and instead of right-sizing it down to 144gb, it let it stay at the original size (since you can do that, as Adam Fox reminded us in an earlier post today). So now we had a 144GB aggregate with a single 300GB disk in it, and also, I have no 300GB spares left! Not good. So 1st level support zeroed out the 144gb drive that had the aborted diskcopy on it, and attempted to fail the 300gb drive with a disk fail -f, in order to bring balance back to this world. Didn't work; turns out if there are no spares, you can't do a disk fail on the command line, not even with -f! So the next answer here was to move all the data on the 144GB aggr to another aggr, wipe out the original aggr and rebuild. But of course we didn't have enough space to do that anywhere, so I was going to have to borrow a 300gb shelf from my friendly netapp office to do the trick, and I could see my weekend slowly slipping away. Luckily it didn't come to that; we escalated it up to support. The final answer involved literally yanking the drive, and some other stuff with the disk fail -i command. This started building back to the original 144gb hot spare, and that took care of the issue. The moral of the story - if you end up accidentally recovering to a bigger spare than the rest of your disks in the aggregate, don't despair! Netapp support can help. Also- it's probably a good idea, in mission-critical environments, to have at least TWO hot spares of each size. Glenn (the other one)

Same aggregate, different size disks?
by Wes Hardin 15 Nov '07

15 Nov '07

Is it possible to have both 144G and 300G disks in the same aggregate, but different raid groups? I can't seem to find any documentation on this. I tried using the ONTAP Simulator to test this, but the simulator seems to have a bug because I was able to add disks of multiple differing sizes to the same raid group (without right sizing them to a common size) and I was even able to add a smaller disk to a raid group of larger disks. -- Wes Hardin

Upgrade firmware, ONTAP and add hardware in one step?
by Stephen C. Losen 14 Nov '07

14 Nov '07

We are adding FC interface cards and new shelves of 750G disks to a FAS960c pair. We need to upgrade ONTAP from 7.1.1.1 to 7.2.3 to support the disks and our system firmware is not the latest. I was wondering if we dare try and do all of this with a single reboot like this: install firmware files and download install ONTAP files and download halt and run update_flash to install firmware power off install interface cards connect new shelves and power them up power up the heads I am concerned that now the filers will come up with new firmware, a new version of ONTAP, and newly installed hardware and disks. Am I asking for trouble? My conservative nature tells me to install the firmware, boot back up, install ONTAP, reboot, shut down, power off, install the new hardware and power back on. It will take only a few more minutes. Steve Losen scl(a)virginia.edu phone: 434-924-0640 University of Virginia ITC Unix Support

nfs tunneling with SSH
by Willeke, Jochen 14 Nov '07

14 Nov '07

Hi toasters, as we are getting more and more secure we do now have some firewalls within our internal network which prevent us from accessing e.g. installation files or some tool-stuff from central stores on our filers. I have tested a little bit with ssh-tunneling for NFS. With my client this works well, but i have trouble doing this with my filers. Here is what i do: client>> ssh -f -L 7777:filer:2049 -l root nstore2 sysstat 100 client>> ssh -f -L 8888:filer:4046 -l root nstore2 sysstat 100 Where 2049 is the filers nfs port and 4046 ist mountd. On the filer i have exported a volume /vol/test to the filer itself. When i now run client>> mount -t nfs -o tcp,port=7777,mountport=8888 localhost:/vol/test /mnt The client hangs and on the filer i see the message: [openssh.dispatch.protocol:warning]: SSH dispatch failed from address myclientsIP, type 90, packet 10 Has anybody ever tried this or has an idea where my problem is?? Or does anybody know if this is absolutely impossible with filers? Best Regards and thanks in advance Jochen

Max raid group size on FAS2050 with SAS disks
by Stephen C. Losen 13 Nov '07

13 Nov '07

I went to the NOW System Configuration Guide and it hasn't been published for the FAS2050. I was pointed to another document that lists max raid group sizes for SATA and FC disks, but not SAS. We are getting a 2050 with 20 SAS disks and I want to know if an 18 disk RAID DP raid group is supported. Steve Losen scl(a)virginia.edu phone: 434-924-0640 University of Virginia ITC Unix Support

CIFS File Services with local filer authentication
by Roger G 08 Nov '07

08 Nov '07

Hello, I am running Ontap 7.1.2.1 with CIFS, and trying to figure out a way to authenticate users locally using the Filer. I only manage 5-10, so I don't want to use an external Active Directory or NIS. I have followed http://www.netapp.com/library/tr/3358.pdf (CIFS File Services in a DMZ Environment), but couldn't make it work. I have configured authentication mode to Workstation: WinNT, and remove the default user mapping of Unix to Win and Win to Unix. I have also created a new group (using useradmin tool) with a "none" role and added a user to this group. All authentication requests from a Win2003 or WinXP, using the local user have failed. Have anyone setup a Filer to work in a similar configuration ? What am I missing ? Thanks. -- View this message in context: http://www.nabble.com/CIFS-File-Services-with-local-filer-authentication-tf… Sent from the Network Appliance - Toasters mailing list archive at Nabble.com.

How many 750G disks can can fit into an aggregate?
by Stephen C. Losen 07 Nov '07

07 Nov '07

We're going to buy some shelves of 750G ATA drives. An aggregate is limited to 16T "raw" (which I presume includes parity disks). Not having any 750G drives yet, we don't know what they size down to. Can anyone tell us how many 750G disks (including parity) that you can stuff into an aggregate? Steve Losen scl(a)virginia.edu phone: 434-924-0640 University of Virginia ITC Unix Support

accessing lun as a raw device using dm-multipathing from a rhel host
by Alexander Schalek 06 Nov '07

06 Nov '07

Hi! I have some troubles with a oracle rac installation on netapp fcp luns. We use rhel4 u5 with dm-multipathing with a 2.6 kernel Currently we have 4 partitioned and multipathed luns maped to the hosts(mpath0-3) but the rac installation exits with an error. I found the following lines in the fcp host utilities setup guide: Accessing LUNs using dm-multipath Accessing LUNs as a raw devices Overview Instead of creating a file system, you can access a LUN as a raw device. Be sure to use the /dev/mapper/ device created by dm-multipath to access the raw device. For the Linux 2.6 kernel used by RHEL 4, do not use the raw interface. Instead open the device using the open call with the O_DIRECT flag. ***** So I have to access the devices using the open call with the O_DIRECT flag!? Can anyone of you guys explain this sentence to me? How do I do that? Many thanks and best regards, Alexander

Symantec Antivirus Corporate Edition 10.1 and vscan on filer
by Richard Distrajo 04 Nov '07

04 Nov '07

Any help on registering the filer to the Symantec antivirus server. I tried to put the filer's hostname /ip address to the symantec antivirus center console but no success. Is this version of antivirus can register the CIFS only filer (ONTAP 7.2.2)? I'm getting error "no network provider accepted the given network path" every time I add the filer's IP address to the symantec antivirus console center...both sides can able to ping each other's hostname and user's permission is already been added as operator on the filer's side.... Thanks for your time on this.... Best regards, Richard Send instant messages to your online friends http://uk.messenger.yahoo.com

Re: R: VMWare CIFS driver
by Alan McLachlan 04 Nov '07

04 Nov '07

Hi Milazzo, You are absolutely correct, and beyond lower performance there's an issue of maintaining the CIFS connection in the case of cluster failover. However, if there's one thing that's true about I.T. it's that if something is _possible_, someone somewhere will have a set of circumstances (not necessarily technical, often financial or political), where that solution makes sense for them. 10 years ago it was a very hard sell to get people to access enterprise databases over any sort of file protocol, now Oracle themselves have vast deployments of Oracle over NFS. And Microsoft SQL Server over CIFS, while not so common, has been used for many years with both reasonable performance and high availability by many NetApp customers (although now we would recommend iSCSI with SnapDrive instead of course), and is a configuration that was originally supported by Microsoft only in the context of NetApp storage. It's very easy to say "that's a stupid idea", but eventually you learn that something that appears to make little sense on it's own can make more sense for a particular environment once all of the issues (technical and non-technical) are considered. There are serious scalability issues with using iSCSI or FCP for VMWare system images (leaving the data volumes aside as a seperate issue that is handled on it's own merits), and the NFS implementation is a very good solution for this apart from improving overall manageability of a large VMWare environment. While I would hestitate before using CIFS for this in any production environment, it may have value in creating a simple and scaleable dev/test solution for a client who then would still use iSCSI or FCP for their production vm images. regards, Alan. ----- Original Message ----- From: "Milazzo Giacomo" To: "M.

I only mentioned it so as not to exclude it as a technical possibility, my followup posts were intended to stop anyone getting too excited about it at this stage.

Windows SnapDrive Query
by Raj Patel 02 Nov '07

02 Nov '07

Simple question - We've just started to utilise some space on a second SAN head and for the life of me I can't remember what I needed to do on the SAN to allow our SnapDrive domain account to connect and create luns on the SAN. I've had a look 'useradmin user list' and 'useradmin domain list' but can't find anything obvious to match our domain 'sduser' account to a SAN account. When I use SnapDrive I get this in the event log - Error code : Access is denied. Verify that you have entered the correct domain and user name during SnapDrive installation and that this account has sufficient privileges to perform this operation. And this as a popup - SnapDrive error Error Description: User sduser does not have the capability to invoke API system-get-version I figure theres something really simple I'm missing or have taken for granted on our other SAN heads in terms of initial setup to use with SnapDrive.
