Question on ndmpcopy and restore_symboltable
by kyle 22 Apr '03

22 Apr '03

I run multiple ndmpcopies daily, and want to know if after each successful copy should the restore_symboltable be removed or should I always leave it around? There is no space issue, I just want to know what the correct way to handle this is. Thanks.

RE: Question on ndmpcopy and restore_symboltable

Hi, As Lance points out if you intend to do incremental restores then you need to leave the restore_symboltable file in place. However, if the transfer is complete then you can remove it.

Identify This Filer, Firmware
by Ryan Ward 20 Apr '03

20 Apr '03

I am trying to identify this product; I bought it off Ebay and of course know little about it. Guessing it's a Netapp based on the ST136403FC drives. NA10 and NA11 firmware currently on them. It's a 7 drive system and it looks like it's in a Eurologic Chassis EL Part Code: XL501R-F-03N-A2 Drive enclosures have Part Code DISK-36GB-10-NF5 again looks like a Netapp part code. Other than that nothing else to revealing Next question ;) Does anyone have the latest flash and utility to upgrade the firmware on these drives? Your help would be much appreciated Thanks Kindly -Ryan

Shrkinking volume on filer
by frank marxs 18 Apr '03

18 Apr '03

I heard someone tell me that if I had a volume with lots of extra space I could pull a drive from that volume and use it to grow an other volume which was full.... 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?

Re: Who to buy additional drives from?
by ScottUCE＠aol.com 17 Apr '03

17 Apr '03

Here are the facts: 1. Adding or attaching uncertified "gray market" NetApp hardware WILL NOT VOID your NetApp warranty or service agreement. In the same vein, attaching other devices to your NetApp (switches, SCSI devices, etc.) will not void your warranties. 2. NetApp DOES NOT REQUIRE "gray market" hardware to be certified, unless the buyer wishes to add the hardware to their NetApp service agreement. If NetApp disputes the above, would an officer of the company please post a detailed response to the Toasters group so that this "debate" can be settled once and for all?

RE: Slow NFS filer performance on WAN connection vs Solaris NFS W AN connection
by Mike McBride 17 Apr '03

17 Apr '03

I would like to add a few more details to the problem i'm having with the poor NFS performance on the Filers using NFS over the WAN(See towards the bottom). The remote Solaris system is 2.8 The NetApp filer(740) is 6.2.2 The Filer has a quad board to Etherchannel ports on a Cisco switch 100mb is the backbone on LAN My first suspicion was maybe the filers were slow on the LAN also but since i was running 100mb I didn't notice the problem. However, this is not the case. I forgot to add i did do extensive testing on the LAN at corporate and I was getting between 6-8.5MBytes/sec from Filer to Solaris system and from Solaris(local disk) to another Solaris(local disk) system. There really was not much difference between the performance on the Filer or the Solaris box. Also, when I used the UDP transport for the remote NFS the performance was terrible. I was seeing a lot of retransmissions. TCP definitely works better on the WAN. Also, the RTT's were the same from the Remote Solaris system to the corporate Filer or from the Remote Solaris system to the corporate Solaris system. I also want to thank several people for their comments on this subject. Unfortunately, i still have been unable to identify the source of the problem.

From a third system ("C") at the same central site run the test talking the Sun ("A") and the 740 ("B"). Run the test on the local LAN and see what you get. If the filer speeds are the same and the Filer is loafing you have a networking problem in the LAN. Try manually setting all network interfaces to Full. Never use auto detection mode. What speed interface is each system, A & B? If the Filer runs at about 6-8.5mbytes per second, assuming a 100mbit LAN interface on the file you still have network problems somewhere between the filer and the VPN box The problems you describe are normally found in the network when the filer is loafing. Check the stats on the LAN interfaces on the filer too, lost frames, retries, etc.. Might be a bad Filer LAN interface.

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.

Can you speed up the time it takes to browse large CIFS shares?
by Hight, Steve - Perot 17 Apr '03

17 Apr '03

Anyone know of any client specific or filer tunable parameters that will speed the time it takes to browse large directories in windows explorer? We have several CIFS shares with 2k or more files/directories in the root of a share. The performance seems to be the same from an NT4, Win2k Pro, XP or Citrix client. This is not really a NetApp issue, the same performance problems exist when trying to browse a share of this size located on an NT server. Any ideas? Thanks, Steve

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'.
