Hello Im playing with a new box running RELENG_7.0 from yesterday. I got two discs with gmirror on ad[6|14]s1a and zfs-mirror on s1d.

Btw, Im doing ZFS'ed root as on wiki, but i added gmirror to the root partition to (and steps to install from one disc to the other, then boot over and add the original disc to mirrors)..

The problem isn't specific to GEOM or ZFS. It's a known issue with two kernel printf()s being called simultaneously. There are older threads discussing the issue.

I can provide details if needed, but > thought I'd ask something somewhat vague for starters. :-) The panic message that you cut from the above text is panic: handle_written_inodeblock: live inodedep In version 1.181.2.17 of ffs_softdep.c (the current copy I have) that panic happens at line 4664 when it attempts to free an inodedep structure and fails because the structure is still needed for some reason. From the comments in the softdep.h file: * The "inodedep" structure tracks the set of dependencies associated * with an inode. So its a softupdates related panic relating to an I/O to an inode that has completed. I can't see how dirhash could have caused this. To see why savecore() isn't saving your cores you might want to check syslog. savecore() should log to syslog at LOG_ERR priority in the DAEMON facility. Changing savecore_flags in /etc/rc.conf to be "-vv" might show up what the problem is if the box panic's and fails to save core again (it might also make boot a lot messier on the console) Regards, Gary P.S. I'm no softupates expert so I don't know what circumstances caused the panic in the first place. ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Re: 2 x quad-core system is slower that 2 x dual core on FreeBSD
Hi, It seems that I'm not the only one who faced the problem that FreeBSD is non productive on multiprocessors platforms. I use OS Linux on my hosting for web-servers, base for all servers is the same m/b S5000PAL ( SR1500), 2 quad kernel cpu Xeon E5320 or E5345, 8Gb RAM. I decided to install FreeBSD 6.2 i386 on one of the servers, and the result was totally non productive. Used software, Apache 2.2.6 (worker) as frontend Proxy, backend Apache 2.2.3 (prefork) By the time we understood,that something was wrong with FreeBSD, there had already been placed about 10 sites with high-capacity and about hundred of usual ones. And this was the limit for FreeBSD. It came along with a great amount of Context Switches, about hundred thousands. I attached the log what was then happening with FreeBSD. After playing with ab (ApacheBenchmark) options, it turned out that even with the following options you can totally down the server: ./ab -n 100 -c 20 -t 30 http://somesite-freebsd.com I copied at the same time somesite.com (php scripts) to Linux server, launched ab with the same options, and saw that it has no influence on work of the server.

The 6.x series was intended to get us back to the stability that we had had pre-SMP integration. I believe we mostly succeeded. One of the major thrusts for 7.0 development was to fix the performance regressions that had been introduced. From the results that I have seen (I am not one of the participants), there has been major progress over the past 2 years in removing yet one bottleneck after another. Recent tests show us to be on a par with Linux on a number of benchmarks; of course, we need more people testing 7.0 in real-world environments to confirm this. You may want to try the 7.0 release candidate on a testbed to see if your results have improved as much as we think that they will have. mcl ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"

I use OS Linux on my hosting for web-servers, base for all servers is the same m/b S5000PAL ( SR1500), 2 quad kernel cpu Xeon E5320 or E5345, 8Gb RAM. I decided to install FreeBSD 6.2 i386 on one of the servers, To be a bit mor specific with my previous reply, in order to use SCHED_ULE you need to be running 7.x (which is quite stable already even being a beta. And of course with 64 bit hardware it's best to run amd64 version of the OS. -Reko ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"

PAE is known to decrease performance, and this is probably 95% of the cause. > Using _ULE might yield a bit more performance as well Yes, in 7.0-BETA3 I'm seeing a 7% increase in performance (sysbench with 8 threads on a 4-core system) with ULE over 4BSD. Both great suggestions. If he needs the high memory support, I would test without PAE just to test the performance (along with changing to the ULE scheduler), then rebuild the system later with amd64 so he doesn't have to use the PAE hack.

Intel S3000AH stall on boot
Hi, I am doing some work for a company that recently bought 2 systems based on the above motherboard and mostly they work fine, however on boot just before userland starts they stall for about a minute. (Just after it starts the second CPU). They have an Adaptec 3405 connected to 4 HDs in RAID10 (using the driver from Adaptec's website). The swi2 is.. 18 ??
