Re: Question : Developing/Making FreeBSD derivative.

I am keen to know and learn more on the process to make a new BSD's derivative/fork from FreeBSD ? There is a distinction. eg PC-BSD is a derivative while DragonFlyBSD is a fork. What do you want? How is the method for customizing/remastering FreeBSD ? The most interesting part is that if we could make the new fork of FreeBSD with its own uname. If I could make my own BSD derivative and used StefanBSD as its uname, it would be awesome. I think you want to read the release(7) manpage. make release BUILDNAME=StefanBSD will get you what you want. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
ZFS performance strangeness
Hi, There are quite a few threads about ZFS and performance difficulties, but i did not find anything that really helped :) Therefor any advice would be highly appreciated. I started to use ZFS with 8.1R, only tuning i did was setting vm.kmem_size_scale=1 vfs.zfs.arc_max=4M The machines are supermicro boards with 48 GB ECC RAM and 15k RPM SAS drives. Local read/write performance was and is great. But exporting via NFS was a mixed bag in 8.1R. Generally r/w speed over NFS was ok, but large reads or writes took ages. Most of the reads and writes were small, so i did not bother. Now i upgraded one machine to 8.2R and i get very good write performance over NFS but read performance drops to a ridiciously low value, around 1-2 MB/s. While writes are around 100MB/s. The network is a dedicated 1GB Ethernet. The zpool uses RAIDZ1 over 7 drives, one vdev. The filesystem has compression enabled. Turning it off made no difference AFAICT Now i tried a few of the suggested tunables and my last try was this vfs.zfs.txg.timeout=5 vfs.zfs.prefetch_disable=1 vfs.zfs.txg.synctime=2 fs.zfs.vdev.min_pending=1 fs.zfs.vdev.max_pending=1 still no luck. Writting is fast, reading is not. Even with enabled prefetching. The only thing i noticed is, that reading for example 10MB is fast (on a freshly mounted fs) but when reading larger amounts, i.e. couple hundred MBs, the performance drops and zpool iostat or iostat -x show that there is not much activity on the zpool/hdds. It seems as if ZFS does not care that someone wants to read data, also idle time of the reading process happily ticks up and gets higher and higher!? When trying to access the file during this time, the process blocks and sometimes is difficult to kill, i.e. ls -la on the file. I read and write with dd and before read tests i umount and mount the NFS share again. dd if=/dev/zero of=/mnt/bla size=1M count=X dd if=/mnt/bla of=/dev/null size=1M count=Y mount is done with this options from two centos 5 boxes: rw,noatime,tcp,bg,intr,hard,nfsvers=3,noacl,nocto thanks --lars ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
Re: Stopping Less from creating Log Files
Lowell Gilbert writes: The secure mode disables log files, but it also changes several other behaviours, so you may not find it to be an improvement. The code supports changing those secure features separately, but only by editing the source; if you go that way, it will probably be much easier to use the ports version of the program instead of the base system's. Very good.Thanks. I looked up what secure mode does and I see what you mean. I will just have to try it and see if I need the ports package or not. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

FreeBSD 8.2 (i386) does not install under Hyper-V
Hi, I'm facing issues with installing and updating of FreeBSD 8.2 (i386) under Hyper-V (Windows Server 2008, Service Pack 2): 1. Update Freebsd 8.0 (i386) - 8.2 under Hyper-V (via cvsup) FreeBSD 8.0 is running fine under Hyper-V on this system since a long time. I had no issues at the time when I installed it. Now I tried to update it to a more recent version: No issues with make buildworld, make buildkernel, but after make installkernel the VM does not boot any longer. Instead the following error message is displayed: freebsd ld-elf.so.1 libc.so.7 unsopported version Elf_Verdef. 2. Then I tried to install FreeBSD 8.2 into a new VM (via ISO image) I received several error messages during the installation, several packages can't be installed: Add of Package xx aborted, error code 0. Debug Screen: ldconfig: warning: /usr/local/Lib: No such file or directory pkg_add: could' t remove temporary dir '/var/tmp/instmp.y3gyg8' pkg_add: leave_playpen: can' chdir back to '' pid 72 (sh), uid 0: exited on signal 11 (core dumped) pid 73 (sh), uid 0: exited on signal 11 (core dumped) ... (several similiar lines with core dumped follow.) Eventually the installation abends with: Could'nt extract the following distributions. This may be because they were not available on the installation media you've chosen: (A lot of packages are displayed.) Then: Cannot dump. Device not defined or unavailable. Automatic reboot in 15 seconds - press a key on the console to abort After the restart the bootloader displays several error messages with dump info and then stops with BTX halted. I did validate the MD5 sum of the image. Another attempt to use VHD as SCSI disk failed as well - the drive is not recognized (No Disks Found!) Then I tested the installation of FreeBSD 8.2 (same image) on my desktop under Virtualbox (Windows 7) successfully. This did work without issues. Unfortunately this does not help with my Windows Server 2008. Is this a known issue?

Kernel loading very slowly with specific (wrong?) loader.conf
Hi, when you use the following loader.conf: # cat /boot/loader.conf hint.sio.1.flags=0x20 comconsole_speed=115200 boot_multicons=yes and have no /boot.config, then booting the kernel is extremely slow. It writes about one character per second on the screen.

Re: Stopping Less from creating Log Files
Date: Mon, 11 Apr 2011 11:36:37 -0500 From: Martin McCormick mar...@dc.cis.okstate.edu Subject: Stopping Less from creating Log Files This is a minor problem but I use more to read Email messages from nmh. If one forgets what screen one is in, it is possible to start typing and create a log file of the message in which ever mailbox directory one is reading out of. The man page for more is actually linked to less even though FreeBSD has /usr/bin/more and less. There is only one executable -- it has two hard links, thus giving the alternate names. I even tried in the .mh_profile to call more with -Oo/dev/null but if you hit a key, the logfile prompt appears and any subsequent key strokes are part of the new file name. This really is only a minor nuisance because it creates junk files that then have to be removed from the directory. So, if there is a way to make more or less not write anything, it would be more or less appreciated. It is said: For every fool-proof system, there exists a sufficiently-determined fool capable of breaking it. We have a winner! For the named programs, more or less, anyway. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
