filesystem full after many mmap/munmap cycles
Hi, I'm running FreeBSD 7.0 RC1 on AMD 64, dual Opteron with h/w raid1 (scsi). I have an app server that uses mmap a lot. After running a long batch (four hours, 5,100+ transactions), I got the message filesystem full (/usr--ufs, local, soft-updates). df -i says plenty of space. I restarted the batch process, and watched app server process carefully with fstat -p, and it looks to be behaving responsibly. The open file list is short, and when I looked up the file names by inum, they were correct. Each transaction does a mmap/munap cycle with a (big ?) file (79M), then copies another smaller file, using mmap to do the copy. fwrite failed on the copy operation; FreeBSD said no space. (When fwrite failed, I called abort, so I have a core and can see where it happened.) pid 29990 (r.fcgi), uid 1001 inumber 359181 on /usr: filesystem full pid 29990 (r.fcgi), uid 1001: exited on signal 11 Filesystem 1K-blocksUsed Avail Capacity iused ifree %iused Mounted on /dev/da0s1g 6297070 3380066 241324058% 183869 640449 22% /usr Is there some file system delay (maybe something related to softupdates) that could accumulate in some way that would cause the file system full message?

[LONG] vmstat: What I/O is blocked and how to fix it?
On two occasions recently, vmstat has showed me that a number of processes are blocked due to I/O. At the same time, the number of disk transactions per second reported is a small fraction of the disk's capability. I am thinking some kind of VM config will help, but based on what I have read, it is almost always best to let the default kernel behavior do its thing. Setup: Dual PIII 1.0 GHz (256MB L1 and L2 cache) 3GB RAM custom kernel (SMP + PF) 5.4-RELEASE one intel fxp0 network interface used (second unused) Case 1: (da0 36GB SCSI) The first case is simple: running spamd-setup to load the huge Composite Blacklist into spamd. The only other things running are sshd and spamd itself. When I run vmstat (vmstat -w 1 -c 10 output attached), it shows ten processes blocked due to I/O, 1 runnable and a total of four disk transactions during this particular ten-second interval. Accoring to postmark [1] da0 is capable of 250 transactions per second. Interrupts look fine (200 of the 300/sec is the clock, right?). No swapping. No network traffic to speak of. High CPU usage. Paging looks really high to me. I have plenty of RAM and swap--so why is it so high? Is there a kernel param I can tweak to improve performance? Note: While this was running, I tried running vmstat -m and got the kmem_map too small error. (I read the FAQ entry and haven't yet rebuilt the kernel using VM_KMEM_SIZE_MAX.) Should I make VM_KMEM_SIZE_MAX 400MB as mentioned in the FAQ? Any other kernel settings to switch from defaults when I build the kernel? Case 2: (mirror/gm0, da0 + da1 300GB SCSI) This case is more complex and more important. This box was heavily loaded, running SpamAssassin + ClamAv in one jail, Courier-MTA + MySql in another, and dspamd + pf in the jail host. It was processing about one incoming email per second, and had 20,000 entries in the spamd greylist and 4,000 in the whitelist. The black list was not loaded. Courier-authlib was using MySQL to figure out where to deliver the mail to for each of 20,000 virtual users. Courier-MTA was calling the ClamAV daemon via TCP/IP from a courier filter and calling SpamAssassin via TCP/IP from maildrop. Spamd (as in OpenBSD, not Apache) and courier were hitting the disk hard--I watched top in m mode [2] and over a five minute period these two apps had about pretty much 50% each of the WRITES. The only thing that jumps out at me is that when things finally do get written to disk, the context switches go really high. Is this a VM issue of some sort? The disk transactions per second are really low; this 300GB SCSI can do 730/sec according to postmark (well, this was testing on a single disk not with the RAID1 gmirror). Thanks for any tips. m [1] /usr/ports/benchmarks/postmark [2] Where can I find docs on what the columns mean in top's m mode? procs memorypage disks faults cpu r b w avmfreflt re pi pofr sr da0 da1 in sy cs us sy id 1 10 0 190424 1653924 1065 0 0 0 1337 0 0 0 796 2931 1971 3 8 89 1 10 0 190520 1653824 17407 0 0 0 17401 0 0 0 356 111 280 44 56 0 1 10 0 167376 1676992 23264 0 0 0 23264 0 0 0 359 119 301 40 23 37 1 10 0 190808 1659240 27728 0 0 0 29152 0 0 0 351 114 297 39 14 47 1 10 0 190936 1676864 18992 0 0 0 17544 0 4 0 352 115 286 39 45 17 1 10 0 191032 1676808 17586 0 0 0 17586 0 0 0 349 115 291 41 52 7 1 10 0 191160 1658572 28025 0 0 0 29374 0 0 0 347 114 270 42 10 47 1 10 0 191320 1676668 24949 0 0 0 23576 0 0 0 346 122 280 36 16 47 1 10 0 191384 1652968 17730 0 0 0 17724 0 0 0 350 111 278 41 59 0 1 10 0 191512 1665912 20409 0 0 0 23688 0 0 0 373 113 304 39 40 21 procs memory page disks faults cpu r b w avm fre flt re pi po fr sr da0 da1 insycs us sy id 0 27 0 345932 2622260 333 0 0 0 318 0 0 0 504 1261 842 8 3 89 0 25 0 341644 2622880 78 0 0 0 215 0 0 0 535 195 575 0 5 95 0 25 0 341644 26228800 0 0 00 0 0 0 455 159 458 0 6 94 0 25 0 341644 26228805 0 0 05 0 5 5 488 165 572 0 4 96 1 25 0 343856 2622408 270 0 0 0 126 0 3 4 472 867 706 1 7 92 0 28 0 355672 2620588 2356 0 0 0 1701 0 44 44 749 6224 1988 24 13 63 1 29 0 357616 2620356 1961 0 0 0 1757 0 44 44 819 7174 2333 46 15 39 1 29 0 357620 2620360 809 0 0 0 735 0 25 25 700 2694 1247 65 8 27 0 29 0

Stale dependency question
On a 5.4 box, pkgdb -F is reporting stale PHP dependencies and I'm not sure of the correct way to fix it. For example (one of nine such messages): php5-mysql-5.0.4_2 - php5-5.0.4_2 (lang/php). We have php5-cgi-5.0.4_2 installed, not php5-5.0.4_2. So ... 1. Portversion tells me that php5-cgi needs upgrading--will doing a portupgrade on php5-cgi fix this stale dependency? 2. Or should I replace the php5 dependency with the php5-cgi when running pkgdb -F? Where can I view a list of a port's dependencies? I tried poking around the ports directories to figure out the dependencies, but /usr/ports/databases/php5-mysql just has a Makefile which points to ../../lang/php5 as the MASTERDIR. Likewise, /usr/ports/www/php5-cgi just has a Makefile that points to lang/php5. This is inside a jail, with /usr/ports mounted nullfs from the jails container. In the container, I did a cvsup and portsdb -Uu. Then in the jail, I do pkgdb -F. Let's see, the only other thing that might be relevant is that as part of the original php5-cgi install, I renamed and moved the php binary to a different place. Then, when pear needed the php binary, we make a symlink from the moved and renamed binary back to the where pear expected it.

Network Debugging
I'm trying to improve the performance of our rural homebrew wireless broadband and am hoping some of the folks here can give me a pointer or two as to what network monitoring tools I should use. Background: - my internet access is five wireless and five wired hops downstream from a 1/2 T1 (ten Buffalo AirStation G54 routers in all). - my connection has a lot of jitter--ping's usually vary from 10ms to 150ms within a two second window - FWIU, jitter is related to congestion - I have setup a FreeBSD box to monitor [1] each router along the path using smokeping. The smokeping charts are showing me some interesting stuff. Here is some data from the past three hours (I am using the smokeping default of 20 pings sent every five minutes): |- Building 1 --| |--- Bldg 0 --... +---+ ++ +---+ | .203 | | .202 | | .201 | | Router In |- wire -| Router Out |- wireless -| Router In | +---+ ++ +---+ avg RTT: 7.3ms 12.1ms 7.8ms % lost: 2.37% 14.25% 2.64% max RTT: 20ms 80ms13ms My FreeBSD box is a four more wireless hops to the left of .203. A slew of questions ... What is going on here? I am confused by the max RTT readings and packet loss stats for .202 and .201. How can a router further away from me have better performance? Over the past 13 hours, the averages are consistent with the three-hour averages, while the Max RTT discrepancies are even higher: .203 / .202 / .201 = 20ms / 145ms / 13ms. Is .202 congested? Is the .202 router bad? How can I debug this further? SNMP? If SNMP, what values should I track/inspect? - # of packets with errors? - # of queued packets? - ??

I have a couple follow-up questions. (1) When do you run cvsup? I don't understand the relationship between cvsup and portupgrade. As I understand things, portupgrade fetches the latest tarball of the given port. If this is indeed the case, why does the portupgrade man page have a tip that says be sure to run portsdb -Uu everytime you cvsup? This tip suggests that you should run cvsup as part of the portupgrade routine. (2) What value do you use for the base parameter in your cvsup file? Should these bookkeeping files be shared between the jail and the mothership?

Re: Tuning FreBSD with specific applications

What could I do to speed those programs under freebsd? - Edit /etc/make.conf and set the processor and compiler optimizations. - Rebuild and install system (world and kernel) - Repost your results here. ;) The BSD handbook has good docs on the last step of this process. Coming from Gentoo, you probably have a good idea what to do in the first step. There is an example make.conf somewhere on you system you can look at for other things to set. If you want to get really detailed, look at the Makefile for R in it's ports directory. There may be some notes as to configure options and performance. FWIU, every port can have it's own set of configure options, and there is a way to put conditionals inside make.conf; for example, if in this ports directory, set this option. I haven't used that yet, but if you search the archives here you will find an example. BTW, don't mess around with the new scheduler. Just use the old BSD one. I did some testing (recompiled gcc) and the old one was faster on a dual processor system. From what someone told me on #freebsd, it works but is not optimized yet. Also, there are somethings you should do when testing speed. You can google to find the references, here's the two items I remember: - use single user mode (no cron) - unplug network cable (no broadcast packets) Have fun! m ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Managing updates in jails
I'm a recent convert to FreeBSD, mainly because of the jail functionality. I am trying to figure out a good system for keeping jails updated and am running against my lack of experience with the compile-from-source approach as well as the different startup scripts. I have pretty much settled on the idea of creating a template or base jail, updating that, then creating a tarball that I can extract over any other jail I need to update. I figure I won't have more than six jails and the complexity of hardlinks and/or unionfs/nullfs for me is not worth the saved disk space. Currently, I have been making buildworld, make buildkernel, etc on the host, then repeating the process inside the template jail. The host is just going to run sshd and ntpd, the template will be apache+mysql+php. A couple questions: - is there a correct way to reuse the makekernel and makeworld done on the host system for the template jail? for example, using DESTDIR and/or NOREBUILD? (I tried DESTDIR initially to install vim into the template jail, but when I ran vim inside the jail, it wouldn't start b/c it was missing a library. So I back tracked and installed the entire ports tree inside the jail and built stuff from there.) It takes around three hours to rebuild everything once, so this will be a limiting factor on how fast I can patch the system (unless I invest in another, faster machine just for compiling). - what directories in the template jail do i need to tar when applying an upgrade to other jails? just /usr and some selected pieces of /etc? - i need to support multiple ip's per jail. i found a patch that applies (pretty much--some wierdness in netinet6) against 5.4, but would like to use the existing rc.conf to manage startup. where would i look to modify the jail startup command to pass multiple ips? - what do people do with the mount command inside a jail--just delete it? are there other commands you take out? Thanks for any pointers, I think a section on jails would be a good addition to the handbook.
