I tried setting my maxd size to 3.5G on a machine with 4gigs ram. It caused squid to seem to rop out on occasion. It seems so odd that on i366, maxd size is so small that one likely needs to set it higher to allow access to more memory. However on amd64, is such a high number that one would need to lower it to prevent accessing too much memory? Something really odd about that. I also found that I could even double the datasize / maxd size to 2X 33554432kB and it would boot and run just fine on a machine with 8 gigs of ram. How weird is that! Did amd64 just cause this setting to add 3 zero's? I can see the legacy documentation for i386 BSD and applications is going to cause some weirdness and problems if not careful. As for squid, just like Sendmail and Apache, yes there and plenty of I do it better and I am newer, alternatives out. But some things stay old favorites for a reason. I will take a look at Varnish, but it seemed much less user friendly to me that squid and much much less feature laden. Also, I saw no way to purge individual files from storage. (something I have to have) So it's always nicer to know how to make things work with what one has or needs to use, rather than just being told to use something else. I have over 30 machines with various configurations of squid in accelerator mode and most seem to work fine. However I will say they do have a preference for running on (1) Single core cpu and SCSI hard drives. On an average server with ~300G of disk, I have over 10M objects in storage. As usual though, I am dealing with a program(squid) that seems to be, Linux first, it happens to also run on FreeBSD second. Even though it seems many people seem to be using it with FreeBSD. Squid has also been great for me to test/beatup on gjournal (which should be in 6 by now and be available standard) and zfs.

FreeBSD-Current 7.0 reporting SCSI drives at 1/2 that of 6.2
Hello I seem to be having a problem similiar to one I found also reported back in April. I am running/testing FreeBSD-CURRENT 7.0 Dated Fri Jul 27. amd64 On boot-up, SCSI disk speed being reported as 1/2 that found when using 6.2. It also seems to be somewhat unstable. FreeBSD 7 da0: SEAGATE ST336753LW HPS2 Fixed Direct Access SCSI-3 device da0: 160.000MB/s transfers (80.000MHz DT, offset 63, 16 bit) da0: Command Queueing Enabled FreeBSD 6.2 da0: SEAGATE ST336753LW HPS2 Fixed Direct Access SCSI-3 device da0: 320.000MB/s transfers (160.000MHz DT, offset 63, 16 bit), Tagged Queueing Enabled However the transfer speeds seem to be about the same. I have tried 2 different TYAN S2881 opteron board with built in Adaptec SCSI (ahd - AIC7902 Ultra320) Why would 7.0 be reporting disks at 1/2 speed? Thanks!

Hi Nicole, I was also having system lockup problems with my FreeBSD-6.x servers running Squid with SATA disks. I could ping it but could not login using SSH. However, in my case, it was due to high mbufs usage. What's your output of the following commands? netstat -mb sysctl kern.ipc.nmbclusters Thanking you... Thanks! Nicole Hi I have my servers behind a load balancer that also does TCP acceleration / offloading so my mbufs usage is pretty low. (it manages about 24 connections tops) However I have been noticing a larger and larger use of swap space. Either because of an increase on our part in the number of files stored or from upgrading to the newest squid versions (2.6-STABLE12 and 13) (last look showed me having 9 million objects in storeage for that one server) So, we could be suffering from the same thing but from different causes. I plan to be adding more memory soon (from 4gigs to 6 and 8) as a test. Also I have been adding SW_Watchdog to my kernels for now. It seems very good so far at sensing the death and rebooting. As well as soon adding some debugging to it to hopefully capture something useful. Be well.

Nicole Ok, so it's an AMD 8111 northbridge versus an Adaptec onboard SCSI controller. 1. What release / version of FreeBSD are you using? You should upgrade to 6.2 STABLE because there have been a variety of issues worked out in previous releases. I have a range of Versions from 6.1-Pre to 6.2-STABLE as of a few months ago. 2. Do you have any logs for activity during the hours when it locks up (in particular anything interesting / fishy popping up)? Nope. That would make it too easy :) They commit suicide without a note. 3. What scheduler are you using? 4BSD, ULE? 4BSD 4. Does your machine (using the SATA controllers) lock up under heavy load? If so, you may have a northbridge cooling issue that you need to put a fan on. For instance, the motherboard that I was using for a while (ASUS P5N-E SLI) was really close to my CPU heatsink, and there was a lot of heat transfer between my northbridge and CPU heatsink, which was raising the onboard temperatures 5~10 degrees C. The new motherboard (ASUS P5B DLX) doesn't do that though. The lockups seem rather random. I have healthd running and they never seem to show very warm. The room is cold and the servers have great fans. Altho healthd can seem wonky as the cpu temp has actually gone below the minimum. Also the -2Volt line seems very low. But some servers runs forever that way. At least with SCSI, since it seems to manage itself as another layer away from the system, you get some error messages. Sort of like windows 3.1 dropping to dos. Verses sata issues where it's just blue screen of death but without even some debugging code. I am going to try the patch chuck Swiger sent me and see how that effects things. Also try a few replacement sata cards. Altho that is always fun especially in 1U servers. As well as seeing if using SAS drives may help if I can find some cheap enough. Do you think that using the ULE scheduler could really help?

How does one bond two interfaces together to share bandwidth?
I am trying to figure out how to bond or combine 2 interfaces together. Such that they each share traffic. I have tried one way, however when I use it I seem to have an odd broadcast occuring on my switch. Such that I am seeing incoming traffic hit some other ports on the switch. Can someone confirm if I am doing it correctly? Perhaps I have a switch issue? Do I also need to bond the ports together on the switch? Sadly the switch they are connected to does not support port bonding. Does that matter? I have not seen any mention of that being required. I have: /usr/sbin/ngctl -f- -SEQ mkpeer fec dummy fec msg fec0: add_iface em0 msg fec0: add_iface em1 msg fec0: set_mode_inet SEQ Thanks for any help!

How does one route traffic to always go in and out via the same port/ip?
Fron a previous post I found I cannot solve my problem via port bonding since I am stuck with a switch that does not support Port bonding or trunking, I would like to then try to setup various interfaces with various IP's to help balance the traffic. Basicly as normal, assign say: ifconfig em0 192.168.1.10 netmask 255.255.255.0 (switch port1) ifconfig em1 192.168.1.11 netmask 255.255.255.0(switch port2) ifconfig em2 192.168.1.12 netmask 255.255.255.0 (switch port3) However if I do this, I get arp complaints because of being on the same network. Now I can stop the arp complaints via setting the below in sysctl.conf net.link.ether.inet.log_arp_movements=0 net.link.ether.inet.log_arp_wrong_iface=0 But, the problem I really have if that all the outbound traffic, goes back out the first port to the default gateway. I have tried everything I could think of, but I cannot figure out how to make sure that traffic that comes in via a particular port, will go back out that port. I am running a load balancing program on this machine. Each IP address would then correspond to an aggrigate of servers that would send traffic back to the machine in response to a request passed to it. However all the responses to the clients, regardless of which IP they came in on, are being sent back via the first port instead of the port/ip they came in on. Any assitance on how to bind an ip and gateway to a port much appreciatted! Sorry if my explanantion sucks. Feel free to ask for more info. Thanks!! They really push this program for running on linux. They offer it for FreeBSD but don't support it as much. I would really like to solve this.

How can I make sure traffic that comes in on one ethernet port/ip goes out that port/IP?
Hello I have a server I am using as a load balancer that has multiple ports. I have set sysctl net.link.ether.inet.log_arp_movements=0 so I could have the multiple ports on the same lan. However, I need to make sure that what comes in via one port/IP also goes out the same port/IP address. I have, lets say: 192.168.1.1 as gateway 192.168.1.2:255.255.255.0 as a managment 10/100 port 192.168.1.3:255.255.255.0 as a 100/1K 192.168.1.4:255.255.255.0 as 2nd 100/1K port When I use this, traffic that comes in on .3 and .4 will still go back out via the .2 default port.

Can you also try just copying a 100MB file from the filer to one of the web servers and record the time? 9907187 bytes/sec for a 16M file. It will transfer in nanotime. So, I believe that eliminates network performance as an issue. Are you running nfsiod? Yes, I show 4 instances running. When going through the issues with Netapp, the reasons given were that we have too many GettAdr/Lookup requests compared to actual reads. So all the NFS IOPS are being used up by these requests. As soon as the webservers get busy, requests pile up. I have tried everything I can think of. The web servers are even mounted read only with no help. My current mount options are: filer:/vol/fvol31/home/13/13 nfs ro,noatime,-r=32768,-T,-b,-R0,-i,-D2,-L 0 0 Mounting noatime for web servers is a good idea but... your noatime option has no effect on NFS mounts (check out the mount man page). You need vol options no_atime_update on the NetApp. Hmm. Drat. We have some web servers that do nothing but send out data, but some that are used for uploading and file manipulation. I will have to make sure that global of an option will not effect what they do. Any advice for sysctl tunes or anything else would be much appreciatted!

Errors Using tcpdump with tcpshow
Hello For some time now I have been watching tcp dumps by sending them through tcpshow -cooked. This has worked quite well on BSD 4.X and also I believe 5.2.1. However, when I tried to do this on a 5.5 or 6.1 server, I get an error. Can anyone help with why I might be getting these errors with later versions of FreeBSD? I have tried all I can think of. tcpdump -i bge1 -s 1518 -lenx | tcpshow tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on bge1, link-type EN10MB (Ethernet), capture size 1518 bytes tcpdump: 1 packets captured 162 packets received by filter 0 packets dropped by kernel bad dump file format Or tcpdump -i bge1 -s 1518 -lenx | tcpshow -cooked tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on bge1, link-type EN10MB (Ethernet), capture size 1518 bytes --- Packet 1 ***Error: Badly formatted Ethernet address 1 packets captured 178 packets received by filter 0 packets dropped by kernel Thanks!!

Re: SATA Cables Suck!

From: Nikolas Britton [EMAIL PROTECTED]
The number one problem I've had with SATA RAIDs
has been the cables! 4
times I've lost arrays because the cables came
loose or some other
stupid problem with the cables.
I need a vendor that has high quality latching
SATA-II cables. Also...
what can we do with the old cables to fix them...
super glue them
on?... Here's a question... Are all SATA cables
rated for SATA-II?
I've never seen a definitive answer to this
question and newegg.com
does not sells SATA-II cables... Also does the
spec call for
shielded cables?
frustrated, need a place to unload thanks.
First google hit SATA-II cable specification:
http://www.satacable.com/
Second google site hit
http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=2076134CatId=84
I've done business with Tiger Direct. They were
prompt for delivery.
Searching for things on their site was annoying,
though.
Adding site:newegg to the search gives:
http://www.newegg.com/Product/Product.asp?Item=N82E16812207001
and
http://www.newegg.com/Product/Product.asp?Item=N82E16812162003
First has a right angle connector.
You were saying?
{^_^}
Well, according to all this, my nice new 3-ware
9550SX SATA II card has SATA I connectors and came
with SATA I cables. That seems, well, disapointing and
odd.

Need Advice for Tuning NFS to place nice with a Netapp
Hi I have several web servers that are attached to a Netapp (network appliance) unit via NFS-3. A few servers are 5.5 and a few are 6.1 for comparison testing. All seem to have lousy performance. When going through the issues with Netapp, the reasons given were that we have too many GettAdr/Lookup requests compared to actual reads. So all the NFS IOPS are being used up by these requests. As soon as the webservers get busy, requests pile up. I have tried everything I can think of. The web servers are even mounted read only with no help. My current mount options are: filer:/vol/fvol31/home/13/13 nfs ro,noatime,-r=32768,-T,-b,-R0,-i,-D2,-L 0 0 I have tried plenty of others. an example nfsstat -c 2 (while working ok) GtAttr Lookup Rdlink Read Write Rename Access Rddir 4357 2976 0125 0 0 3425 0 4173 2836 0115 0 0 3288 0 4254 2912 0106 0 0 3344 0 3668 2528 0 99 0 0 2880 0 3992 2746 0101 0 0 3136 0 3916 2706 0 93 0 0 3080 0 3748 2551 0106 0 0 2948 0 4121 2851 0 86 0 0 3231 0 Any advice for sysctl tunes or anything else would be much appreciatted!

Re: best way to copy from one fbsd box to another
--- David Banning [EMAIL PROTECTED] wrote: I am installing a new server and have to copy many files from old server to new. I have connected a windows box to each via samba, and am dragging from one to the other via the windows box. This might seem like a silly question, but what is the way to copy -directly- from one fbsd box to another? If you have a secured connection I like using rcp. (complied without the evil conversion to using scp) scp works too but has more overhead and for rsh maintains permissions better. (I think) One thing to keep in mind is that if you are copying OS files, you may run into files that have the file (immutable) flags set such that even as root, you cannot update or overwrite them while in multiuser. (see chflags) Hope this helps. Nicole The Large Print Giveth And The Small Print Taketh Away -- Anon __ Do You Yahoo!? Tired of spam? Yahoo!

Jeremy Kister http://jeremy.kister.net./ Hi Jeremy Thanks for the suggestion. Would using the -w do anything for me since I am mounting read only? I will try 16384 again however, as they could not settle on wether 16k or 32k would be best. Thanks Nicole The Large Print Giveth And The Small Print Taketh Away -- Anon __ Do You Yahoo!?
