The f760 is rated (per SPEC, http://www.spec.org/osg/sfs97/results/) is abround 7500 NFSops with the read/write mix they put on it. In one service (with almost equal reads and writes), we see somewhere around 75% cpu with 4k nfsops and 2M/sec in and 2M/sec out, on average. The peaks are much higher, and disk reads/writes are quite high. The cache age is low (3 min). This is on a loaded f760 with 1GB of cache, 3 raid groups of 14 drives (9GB) each. On the other hand, in a mainly read environment I have seen filers push the 9k+ nfsops and pushing 10M/sec with highg cache age, while the cpu is still not higher than 80%. It all depends on your mix and your configuration. Alexei

Strange routing problem.
by Mohler, Jeff 26 Jul '99

26 Jul '99

Greetings: I have a routing problem on a 2.6 box, here is the detail. I want to send traffic out to 10.16.118.20 on qfe0, which will be a private 10/100 segment to the NetApp for NFS traffic. I am only using 10.16.118.0 in this message, because 119.0 does the same thing on qfe1. This is a prototype box to configure and test first, then deploy to the field installed Solaris machines. The network is like this: NETAPP-F760:e0 public interface connected to 3/1 on a Cat 5505 Switch, on VLAN 223 (public addressed traffic) NETAPP-F760:ech1 channel of e1a and e1b on 10.16.118.0 on 5/1-2 (channel) on VLAN 118 - 10.16.118.10 NETAPP-F760:ech2 channel of e1c and e1d on 10.16.119.0 on 5/3-4 (channel) on VLAN 119 - 10.16.119.10 On the sun box I have: Sun:e0 public interface connected to 3/2 on Cat 5505 on VLAN 223 Sun:qfe0 10.16.118.23 connected to 3/15 on Cat 5505 on VLAN 118 Sun:qfe1 10.16.119.23 connected to 3/16 on Cat 5505 on VLAN 119 Sun:qfe2 10.16.254.23 not yet connected for ADSM traffic Sun:qfe3 10.16.3.117 connected to management LAN The interface is up, here is netstat output: Routing Table: Destination Gateway Flags Ref Use Interface -------------------- -------------------- ----- ----- ------ --------- 151.142.223.0 151.142.223.53 U 2 282 hme0 10.16.118.0 10.16.118.23 U 2 5351 qfe0 10.16.119.0 10.16.119.23 U 2 0 qfe1 10.16.3.0 10.16.3.117 U 2 3 qfe3 default 151.142.223.1 UG 0 129 127.0.0.1 127.0.0.1 UH 0 4 lo0 A traceroute to 10.16.118.10 shows the machine choosing hme0 for a route...why? # traceroute 10.16.118.10 traceroute: Warning: ckecksums disabled traceroute: Warning: Multiple interfaces found; using 151.142.223.53 @ hme0 I have an NFS mount on the Sun box to the filer using the 10.16.118.10 address, and it even shows up as the propler hostname:/<path> in the 'df' output. I can blow large amounts of dd traffic to/from the mount, and I see NO traffic on the correct Channel (ech1) on the Filer.

Shelf2 SCSI Drives
by John Tatar 25 Jul '99

25 Jul '99

Does anyone know where I can get shelf2 SCSI drives (And don't say netapps;-)? I didn't realize when Netapp announced that they were discontinuing some products that they were discontinuing their entire line of SCSI products. Now I can't add disks to the shelf2 that I bought partially filled with disks last year. TIA JT -- =================================================================== John J.

Id'ing stale NFS file handle - solaris mounting netapp?
by Elizabeth Schwartz 23 Jul '99

23 Jul '99

We have a solaris 2.6 server with MANY users, that is getting regular "NFS stale file handle" errors. We have the file handle from /var/adm/messages but we do not know which process is generating the error. Is there anything we can do to get a file name from the file handle, to help identify which process is the source? Rebooting this machine is a last resort option since it is a primary user server (meaning we'd have to do it in the wee hours) thanks Betsy (new to the list, hello all!)

Re: restore from dlt is failing

Hmmm, ARG b is specifying a blocksize of 1 KB, it looks to me as though you should specify 63. I presume that you know what you are doing with ARG s (File 33 of n on the tape). #ifdef PARANOID_MODE Also, unless you are planning to write on the tape, it should be write protected, just to protect against fumble fingers or other errors. #endif /*PARANOID_MODE*/ <scw> > > I'm trying to do a restore from tapes where the netbackup images have expired.

Unusual request
by Sitzkrieg Redundus 23 Jul '99

23 Jul '99

Hi! I'm fairly new to the list, so here we go. I've got a 630 sitting in a rack happily serving up webpages to 12 front end machines via NFS. The NetApp needs to be Y2k tested, however I can not test a live machine. Yes, I know NetApp has certified ONTAP and the head unit itself. Doesn't matter, I work for an ISP, and we trust nothing. :) Does anyone have/know of someone who has a 630 head unit that I could buy outright or borrow/lease for a couple of weeks (at most, I should think) to do some testing? My NetApp salesdude has informed me that NetApp doesn't have a single 630 anywhere in the company, so my options are somewhat limited. I can a) scrounge a 630 or b) buy a 760 (which while an option, isn't all that high on my list of happy things). Thanks. Noah Robin

strange sysstat output
by Graham C. Knight 23 Jul '99

23 Jul '99

This is an F540 running 5.2.1P2D14 The filer is basically doing nothing - but every 5 seconds or so the CPU goes up to 80 or 90% and stays there for 6 or 7 seconds. We've been having trouble with systems that have NFS mount to this filer hanging. The only solution (thus far) has been to reboot the filer. I'm not too worried about it because this system was due to be replaced this Sunday, but it'd be a good one for the data banks if anyone knew what caused this type of behaviour. sysstat is below. Thanks, Graham sysstat 1: CPU NFS CIFS HTTP Net kB/s Disk kB/s Tape kB/s Cache in out read write read write age 1% 3 0 0 1 0 0 0 0 0 2 1% 2 0 0 0 0 0 0 0 0 2 2% 30 0 0 59 109 0 0 0 0 2 81% 26 12 0 16 148 0 0 0 0 2 90% 5 12 0 5 2 0 0 0 0 2 90% 3 12 0 4 2 0 0 0 0 2 92% 3 9 0 3 2 800 136 0 0 2 89% 2 11 0 4 2 16 732 0 0 2 90% 3 12 0 13 2 0 0 0 0 2 90% 2 13 0 4 2 0 0 0 0 2 13% 2 1 0 0 0 0 0 0 0 2 1% 10 1 0 2 2 0 0 0 0 2 1% 2 0 0 0 0 0 0 0 0 2 1% 4 0 0 9 1 0 0 0 0 2 1% 2 0 0 0 0 0 0 0 0 2 80% 3 12 0 4 2 0 0 0 0 2 90% 2 12 0 4 2 0 0 0 0 2 92% 1 12 0 4 2 312 0 0 0 2 93% 2 12 0 4 2 16 668 0 0 2 90% 4 12 0 4 2 0 0 0 0 2 CPU NFS CIFS HTTP Net kB/s Disk kB/s Tape kB/s Cache in out read write read write age 89% 4 11 0 4 2 0 0 0 0 2 92% 5 10 0 4 2 0 0 0 0 2 1% 10 0 0 2 2 0 0 0 0 2 1% 2 0 0 0 0 0 0 0 0 2 1% 9 0 0 1 1 0 0 0 0 2
