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.

Hi Mark, I just tried this on a lab filer here running 6.4.1R1 and in workgroup mode on an NT4.0 Workstation client (as still used by many of our government Novell customers - some are even still using Win98...) the mapped drive still shows up as FAT - no ACL's.

Filer shelfs on Linux x86
by Ben Rockwood 16 Apr '03

16 Apr '03

Hello Toasters. I've done some testing recently with using NetApp shelfs (FC8/FC9) attached directly to a Linux box. It's worked very well, and I'm happy with the setup. There are some rough points, but the implimentation is pretty straight forward. I had started writting an article on how to do things end-to-end, but somehow half way thru just didn't see the point. Anyway, here are some interesting tidbits to wet the lips of anyone with shelfs sitting unused. Single FC8 shelf with 18G disks: [root@nexus /]# df -h Filesystem Size Used Avail Use% Mounted on /dev/evms/fc8_volume 118G 15M 118G 1% /filer_shelf [benr@nexus benr]$ bonnie++ -d /filer_shelf/ Version 1.03 ------Sequential Output------ --Sequential Input- --Random- -Per Chr- --Block-- -Rewrite- -Per Chr- --Block-- --Seeks-- Machine Size K/sec %CP K/sec %CP K/sec %CP K/sec %CP K/sec %CP /sec %CP nexus.homeste 1256M 5604 81 19477 18 15546 17 6861 98 59964 37 677.7 5 ------Sequential Create------ --------Random Create-------- -Create-- --Read--- -Delete-- -Create-- --Read--- -Delete-- files /sec %CP /sec %CP /sec %CP /sec %CP /sec %CP /sec %CP 16 998 7 +++++ +++ 376 2 422 5 +++++ +++ 401 3 And this is 2 FC9 shelfs with 36G disks: Filesystem Size Used Avail Use% Mounted on /dev/evms/fc9_vol 474G 60M 474G 1% /filer_shelf [benr@nexus benr]$ bonnie++ -d /filer_shelf/ Version 1.03 ------Sequential Output------ --Sequential Input- --Random- -Per Chr- --Block-- -Rewrite- -Per Chr- --Block-- --Seeks-- Machine Size K/sec %CP K/sec %CP K/sec %CP K/sec %CP K/sec %CP /sec %CP nexus.homeste 1256M 5636 82 33744 33 23145 28 6306 93 60607 37 712.0 7 ------Sequential Create------ --------Random Create-------- -Create-- --Read--- -Delete-- -Create-- --Read--- -Delete-- files /sec %CP /sec %CP /sec %CP /sec %CP /sec %CP /sec %CP 16 775 5 +++++ +++ 345 2 326 4 +++++ +++ 358 3 In both cases, the volumes that were build were striped across all avalible disks, using a stwidth of 16k. LVM was used under EVMS control to all volumes. As you can see from the benchmarks, the block read performance was excellent. For the tests I used my standard Linux workstation, a very slow Dell PIII 550Mhz with 512M RAM. JFS was used as the filesystem. The following are some notes for anyone who might wanna try this: a) DO NOT USE THE KERNELS QLOGIC DRIVER. It sucks! And don't think that you can just push the dev count to 255 and get past it, that only works for 3-4 devices. If you use a QLA2100 grab the QLA2200 driver from Qlogic.com, hack the makefile to build you a QLA2100.o module, the code is there but they don't advertise it. b) I tests all this with a custom 2.4.20 kernel, works great, added EVMS patches. c) EVMS rox, much more fun than LVM raw, but takes much longer to set things up due to the abstration layers added d) You'll have to wipe out the 2 partitions on the disk, which fdisk can't do. You'll need to dd over the first 1k to manually wipe the partitioning scheme. e) If your not already using DevFS I highly suggest it before piling shelfs on. If anyone wants more information or benchmarks, mail me directly and I can send my notes over. benr.

Who to buy additional drives from?
by David L Kindred (Dave) 16 Apr '03

16 Apr '03

I need to add some drives to the DS14 on our F810, but had a couple of questions. Since the Filer has performed so well, I haven't had much need to deal with it, which is good, but it also means I'm not as familiar with it as I'd like. It seems I only have time to learn about the things that break :( I have been able to find answers to the technical questions on NOW, so I don't have to act stupid about those. I do have one non-technical questions left though: When the time comes to buy the drives should I go back to the VAR we bought the system from, or direct to NetApp, or should I consider some other source? We are maintaining NetApp support, so we would need an "approved" vendor, etc. Thanks. -- David L.

RE: Reassigning low UIDs
by Ben Rockwood 16 Apr '03

16 Apr '03

The generally accepted low bound is 500. Which goes for both UIDs and GIDs. As for re-assigning, sounds like a job for PERL or some expertly crafted "find" commands. You could create an index in a 2-dimensional array (or just a flat file) mapping new to old UID and then just spider the mount points in question. Just make sure you heavily test it prior to unlessing it. benr. -----Original Message----- From: Jim Davis [mailto:jdavis@cs.arizona.edu] Sent: Wed 4/16/2003 10:43 AM To: toasters(a)mathworks.com Cc: Subject: Reassigning low UIDs Our Unix-side password files go back to the days of SunOS 3.x (if not before), so we have some users with UIDs less than 100. Nowadays this causes problems with NFS on, eg, Linux boxes that seem to assume any UID under at least 1000 is fair game for placeholder accounts. After struggling with this for a while it looks like it's time for a wholesale UID reassignment for those users. - what's a "safe" lower bound for UIDs? 1000? 10000? We'd rather not have to do this more than once! - is there some slick way to reassign UIDs en masse on a filer? We could run 'chown -R ...' on the admin host, but is there a better way?

If you are running with ONTAP 6.1.1 or later you can create up to 96 local users in workgroup mode and use NTFS security with NTLM authentication. Even without local users you can use UNIX-style security if you are willing to use /etc/passwd accounts (which unfortunately implies the use of plaintext passwords over the wire during CIFS login). However, it is true that for the very best available CIFS security (which uses Kerberos authentication) you do have to have the filer installed in a Win2k domain. Mark

Yes Option 1 implies that every packet that comes from the Filer is dissassembled on the Novell gateway machine and reassembled outbound in the format defined.

"df" output on filers running 6.3.1R1D1

G'day. Does anyone here happen to run ONTAP 6.3.1R1D1 on a filer with more than two volumes on it? If so, what order does a "df" command on the console report them in? We just upgraded a two-volume filer to 6.3.1R1D1 and the reporting order reversed itself from vol0, vol1 to vol1, vol0. This, in turn, goofed up the SNMP monitoring bits by reversing the index-to-volume numbers.

RE: CIFS in Workgroup mode
by Alan McLachlan 16 Apr '03

16 Apr '03

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?

CIFS in Workgroup mode

Does anybody run CIFS shares in workgroup mode? That is not booted/authenticated with a PDC? I have the joy of trying to make my machine work in a Novell environment and no DC and would love to share ideas with other lucky souls like me.... TIA -Bob Borowicz

Andy, I killed the threads but there are two other processes listed relating to ndmp: ndmpdclassloader ndmpdserver Should those be deleted also?

Brian, Thanks for the reply. I'm in the java shell and ps in fact returns several Ndmpd threads even though > ndmpd status indicates no sessions active. But when I try to kill, the following returns: jsh> kill Thread-517 Arg expected Is there a switch I'm missing, like kill -9 <threadName> By the way the filer is running the most current version of ONTAP for the model ( F520 ) and has been rebooted in the last 42 days which postdates the timestamp on the snapshots. It looks like the kill solution or boot from floppy into maintenance mode and deleting them are going to be the only workable solutions. Regards, Joseph C.

RE: Legato and NDMP

Gavin, How long is the root password on the Netapp? You will need to make sure it is 8 characters or less otherwise a NDMP connection will not be able to be made from the Legato Server. Mike -----Original Message----- From: Gavin Kelman [mailto:gavin@metahusky.net] Sent: Tuesday, April 08, 2003 4:42 AM To: toasters(a)mathworks.com Subject: Legato and NDMP We've just received a nice new F825, which we're trying to integrate into our exsiting Legato Networker backup system. I've been speaking to our Legato support, but they're not getting very far, and each day that passes is another day for us without backups. We have a Quantum ATL1500 jukebox directly attached (Robot controller and one drive) to a Sun box, which is a Legato storage node. The 2nd SCSI drive is connected to the back of our F825, which picks it up fine, and is configured as an NDMP device in Networker. Now, the problem is, Networker complains that it can't establish an NDMP connection to the F825, even tho NDMP is enabled on the F825, and I've double-checked the username is root and the password is correct. Attempting to do an inventory in nwadmin fails on either device in the jukebox. Also, NDMP doesn't do incrementals the normal way, so I was thinking of just backing up the F825 over the NFS mounts, but I hear that's not a good idea with Legato. We're running DOT 6.3.1r1 and Legato Networker 6.1.3. Anyone have any suggestions, apart from "stop using Legato"?

RE: rsh sysstat (was: 2 telnet sessions)
by Ehrhart, Rick 14 Apr '03

14 Apr '03

Be careful about running non-terminating commands from rsh. See burt 88028 for details. When a non-terminating command executed via rsh is aborted, it leaves a rsh session hanging of the filer. If the abortions continue, all the rsh sessions will be used up. Try rsh <filer> "sysstat -c <count> 1". The count is the number of times the sysstat will execute. - Rick - ----------------------------------------------------------------- Rick Ehrhart Network Appliance "I believe in nothing, Everything is sacred." > -----Original Message----- > From: Neto, Antonio Jose Rodrigues > Sent: Monday, April 14, 2003 8:59 AM > To: devnull(a)adc.idt.com; toasters(a)mathworks.com > Subject: RE: 2 telnet sessions > > > Hi, > > Could I give a suggestion? > > Enable rsh. > > tty1 > #rsh filer sysstat 1 > > tty2 > #telnet filer > > Hope this helps > > regards > > neto > > -----Original Message----- > From: devnull(a)adc.idt.com [mailto:devnull@adc.idt.com] > Sent: Monday, April 14, 2003 12:26 PM > To: toasters(a)mathworks.com > Subject: 2 telnet sessions > > > Dear Toasters, > > I am trying to see if its possible to connect to the filer > via more than 1 > telnet session. > > The only "options" i see is telnet.enable > > I would like to be able to connect to the filer via 2 telnet sessions, > maybe even run sysstat under 1 and do "work" on the other. > > Please advice, > > Thanks, > > /dev/null > > devnull(a)adc.idt.com > > P.S: Running ancient versions 6.1.1R2 and 6.1.2R1. >
