RE: Shrkinking volume on filer
by Bui, Marcus 17 Apr '03

17 Apr '03

Don't know about your first question.. But just a few days ago, both of my F760c were constantly 100% CPU usage. Accessing files was really slow. Both home folder (MS clients) volume on each of Filer was at 92% capacity. Expanded the volume (added 6 drives). CPU usage is now around 60% on both Filers. You won't see the performance improvements right away because it takes a while for the new disk to even out with the existing ones. It took about 4 hours before I see any performance gain. Be careful not to add too few disks causing the new disks to be 'hot'.

I know we can grow a volume by adding a drive on a filer, but I haven't heard of the possibility of shrinking a volume by pulling a drive. Did I miss something or is this a new feature? BTW: Anyone seen a drop in performance after growing a volume which was almost full?

I don't know if this might help you but this is what I'm doing with my filer and MRTG: http://redhook.univ-wea.com/mrtg/ Pike is the name of my filer, look for that..... -MannyO -----Original Message----- From: Deepak Soneji [mailto:sonejideepak@hotmail.com] Sent: Wednesday, April 16, 2003 7:57 PM To: toasters(a)mathworks.com Subject: MRTG - MIB for Filer Capacity vs Utilization Hello I am using MRTG - MIB downloaded from netapp.com which provides me wonderful historical data.

RE: Resize existing volume
by Alan McLachlan 17 Apr '03

17 Apr '03

Patrick, This type of situation in mixed size volumes can be alleviated somewhat by double rebuilding with manual fail/unfail operations. However, if you're getting bigger replacements in a mixed size volume this situation can be difficult to avoid. See if NetApp or your will loan you a shelf of 36's for a weekend. Then you can build a new temporary volume and copy your data to it. Then blow away and rebuild your existing shelf as permitted by the physical disks (36GB Parity, 3x36GB data, 3x18GB data - I assume your hot spare is a 36). Then copy your data back and return the loan shelf. Voila! An extra 68 odd GB will appear. regards, Alan McLachlan Senior Systems Engineer Storage Management Solutions ASI Solutions www.asi.com.au Ph +61 2 6230 1566 Fax +61 2 6230 5343 Mobile +61 428 655644 e-mail amclachlan(a)asi.com.au -----Original Message----- From: Patrick Lee [mailto:pat@patlee.org] Sent: Saturday, 15 March 2003 7:59 AM To: toasters(a)mathworks.com Subject: Resize existing volume I have a Filer 720.

RE: CIFS in Workgroup mode
by Mark McGilvray 17 Apr '03

17 Apr '03

Along the NetWare support lines, we are hoping that iSCSI will provide the support we need for Novell. From what we understand the NetWare iSCSI initiator will ship in the NetWare 6.5 box in June. Any thoughts? Mark >>> Alan McLachlan <amclachlan(a)asi.com.au> 04/16/03 12:17AM >>> Robert, One problem is that in workgroup mode NTFS security isn't available. In fact, no real security is available... There appear to be two options to using a filer in a Novell environment: 1) The "gateway" Novell server approach. This involves using a Novell server running Novell NFS Services (with lots of CPU and RAM) with a direct back-to-back link to the filer to act as an I/O path. Clients and application hosts only see the Novell server, while the filer thinks the Novell server is a Unix NIS server that also happens to be it's only client :o). Security is a subset of Novell permissions as available by mapping Unix permissions. The drawback here is that the Novell server itself will be an I/O bottleneck. 2) eDirectory and Windows integration. For this you need a DC, as you have identified. The Windows DC runs the Novell eDirectory client and the security is synchronised with Novell Account Manager. All clients that need to access the filer need to have the CIFS redirector running. Permissions are mapped by Novell Account Manager. An issue with approach 2 is that when passwords are changed by a helpdesk directly in eDirectory, they may not be synchronised immediately. If anyone has found a workaround for this please respond. regards, Alan. -----Original Message----- From: Robert Borowicz [mailto:rbaus@swbell.net] Sent: Wednesday, 16 April 2003 6:26 AM To: toasters(a)mathworks.com Subject: CIFS in Workgroup mode Does anybody run CIFS shares in workgroup mode?

Hi Toasters, I have a F820 (6.3.1R1) which get FC error every during boot up. But once the Filer is up, all volumes are available and can see all disks. Do 'sysconfig -c' and no errors. Try swapping the cable around but same error at boot up. Any ideas? Starting Press CTRL-C for floppy boot menu ispfc: Fibre Channel adapter 8b appears to be unattached/disconnected. If adapter is in use, check cabling and seating of LRC cards in disk shelves.

RE: Slow NFS filer performance on WAN connection vs Solaris NFS W AN c onnection
by Alan McLachlan 17 Apr '03

17 Apr '03

Mike, This is very interesting, particularly considering that on regular LAN connections NetApp filers blow away Sun boxes (on SpecSFS anyway). I half expect a "filers can't deal with being asked to run that slow" response from NetApp.... :o) Seriously though, OnTap does not use an NFS daemon. I believe NFS is handled in a state-machine fashion within the Ontap RTOS kernel. It's possible that what your seeing is the result of a timing condition that doesn't show up on faster links. Are you running NFS in sync or async mode on the client? regards, Alan McLachlan Senior Systems Engineer Storage Management Solutions ASI Solutions www.asi.com.au Ph +61 2 6230 1566 Fax +61 2 6230 5343 Mobile +61 428 655644 e-mail amclachlan(a)asi.com.au **** ASI Solutions Disclaimer **** The material transmitted may contain confidential and/or privileged material and is intended only for the addressee.

Slow NFS filer performance on WAN connection vs Solaris NFS WAN c onnection
by Mike McBride 16 Apr '03

16 Apr '03

We have several engineers working from home using Solaris boxes and utilizing VPN's to the office. Typical application use is Cadence. What i have noticed is the NFS performance on the Filers are almost 50% slower than the performance of the Solaris machines. I have run several tests including cp, ftp and utilizing ping roundtrip times, traceroute, snoop and tcpdump to monitor activities between home SUN systems and file systems at work. I have also tested NFS using different transport protocols(tcp/udp) modifying rsize/wsize buffers and using NFS2 and NFS3 versions of NFS. The filers and the Solaris systems at cooperate are on the same subnet - there is no differences in the routing. FYI - the VPN's at home are all Linksys VPN cable/dsl routers configured for Site to Site VPN connections to corporate office. The problem is definitely with NFS and it is isolated to the Filers. I am confused why the performance of the NetApp NFS would be so poor compared with NFS on the Solaris systems. Now, I know NFS on a WAN is slow and VPN encryption is going to degrade the performance severely, but I am wondering why NetApp NFS performance is much worse than Solaris NFS performance. Basically, when accessing files on a Solaris system(local disk) at the corporate office from home i'm getting about 915KBits/sec. When accessing the same files on a NetApp(F740) at the corporate office from home i'm getting about 510KBits/sec. The transfer mechanism is NFS. When using FTP i get the same 915KBits/sec on the Solaris(local disk) and Filer. The load on the Filer at the time of testing is minimal. Anyone have any insight on this subject? Any feedback would be appreciated since I put quite a bit of time in this to try and understand the problem here. Thanks, Mike McBride Silicon Wave, Inc.
