Yes. You overwrite your first ifconfig_bridge0 setting with the second one. These are shell variable initializations, not executable statements. There are various ways to fix the problem.

Bridge Interface Members
Trying to configure a bridge interface with two member interfaces, fxp0 and re0. Configuring the interface from scratch manually works fine but when I add config entries to rc.conf the two member interfaces aren't added at boot. Bridge0 is created it just doesn't have any members. From the serial console I can manually add the two member interfaces and everything is fine but obviously I'd like it to work without manual intervention. Any ideas?

ZFS + GPT with root on memory stick and mirrored SATA drives
Posting the below for input. The bulk of this is from a guide that Morgan Wesström posted to this list. Some of it is taken from the root on ZFS wiki entries on freebsd.org. Some from a pjd post here: http://blogs.freebsdish.org/pjd/2010/08/06/from-sysinstall-to-zfs-only-configuration/ And then there's this that Svein Skogen posted to the list: I usually (today) set up something similar. I sysinstall FreeBSD onto a CF card with the one-big-root method, then create a zpool (on spinning-metal-storage) where I create the usr, tmp, var fs'es, tar|tar the originals over and fix the mountpoint info on the zfs'es. Then I add swap on a zvol (since I don't know how to properly use a kernel dump, I don't need swap to store it). I'm setting up a new home server and I always agonize over partitioning. So the steps below install the base system with zfs root on a usb stick and /tmp /usr /var and swap on mirrored sata drives. I've tested these steps and everything works but before I press on with actually configuring and using the server, does anybody have any input on whether I should or shouldn't do it this way? ZFS best practices suggests that having elements of the root filesystem on different pools is a bad idea. So that might be strike 1. Memory Stick / /bin /boot /dev /etc /lib /libexec /media /mnt /proc /rescue /root /sbin /sys -- /usr/src/sys Hard disk zpool --- /tmp /usr /var swap on zvol Separate zfs datasets - /tmp /usr /usr/home /usr/local /usr/obj /usr/ports /usr/ports/distfiles /usr/ports/packages /usr/src /var /var/log /var/audit /var/tmp Install Procedure (Mostly by Morgan Wesström) - Select your country and keyboard layout. Enter the Fixit environment and use the live filesystem on your DVD. Your usb memory stick will most likely be da0 but you can (and should) check it with camcontrol devlist before you continue. Create a new GPT partitioning scheme: # gpart create -s gpt da0 Create a 64KiB partition for the zfs bootcode starting at LBA 1920: # gpart add -b 1920 -s 128 -t freebsd-boot da0 Create a zfs partition spanning the remainder of the usb memory stick and give it a label we can refer to: # gpart add -t freebsd-zfs -l FreeBSDonUSB da0 (The starting LBA for the first partition is there to align the partitions to the flash memory's erase block size. This is particularly important for the main zfs partition. The main partition above will start at exactly 1MiB (LBA 2048) which will align it to any erase block size used today. This alignment is also of great importance if you use this guide to install FreeBSD to one of the newer harddrives using 4096 byte sectors.) Install the protective MBR to LBA 0 and the zfs bootcode to the first partition: # gpart bootcode -b /dist/boot/pmbr -p /dist/boot/gptzfsboot -i 1 da0 Create /boot/zfs (for zpool.cache) and load the zfs kernel modules: # mkdir /boot/zfs # kldload /dist/boot/kernel/opensolaris.ko # kldload /dist/boot/kernel/zfs.ko Create a zfs pool and set its bootfs property: # zpool create zrootusb /dev/gpt/FreeBSDonUSB # zpool set bootfs=zrootusb zrootusb Switch to fletcher4 checksums and turn off access time modifications: # zfs set checksum=fletcher4 zrootusb # zfs set atime=off zrootusb Create zfs mirrored data pool on SATA disks # zpool create zdata mirror /dev/ad4 /dev/ad6 # zfs set canmount=off zdata # zfs set mountpoint=/zrootusb zdata # zfs set checksum=fletcher4 zdata # zfs create zdata/tmp # zfs create zdata/usr # zfs create zdata/usr/home # zfs create zdata/usr/local # zfs create zdata/usr/obj # zfs create zdata/usr/ports # zfs create zdata/usr/ports/distfiles # zfs create zdata/usr/ports/packages # zfs create zdata/usr/src # zfs create zdata/var # zfs create zdata/var/log # zfs create zdata/var/audit # zfs create zdata/var/tmp Create swap zvol on zdata pool # zfs create -V 5G zdata/swap # zfs set org.freebsd:swap=on zdata/swap # zfs set checksum=off zdata/swap Extract at a minimum, base and the generic kernel: # cd /dist/8.1-RELEASE/base # DESTDIR=/zrootusb ./install.sh # cd ../kernels # DESTDIR=/zrootusb ./install.sh generic Delete the empty, default kernel directory and move the generic kernel into its place: # rmdir /zrootusb/boot/kernel # mv /zrootusb/boot/GENERIC /zrootusb/boot/kernel Make sure the zfs modules are loaded at boot: # cat /zrootusb/boot/loader.conf zfs_load=YES vfs.root.mountfrom=zfs:zrootusb kern.cam.boot_delay=1 ^d Create /etc/rc.conf.

Bridging Gigabit and Fast Ethernet Interfaces
if_bridge(4) says: The if_bridge driver currently supports only Ethernet and Ethernet-like (e.g., 802.11) network devices, with exactly the same interface MTU size as the bridge device. Am I correct to assume then that I can bridge a gigabit interface and a fast ethernet interface and that one of the negatives of doing this is that Jumbo frames couldn't be used on the gigabit side? I've got an Atom based server with an onboard gigabit nic and only one PCI slot. The server sits physically close to my 10/100 switch that hangs off my firewall. I was thinking of putting a 10/100 nic into the single PCI slot and running that to the 10/100 switch for internet access and then running cable across the room from the gigabit interface to a gigabit switch on my workbench. Wired gigabit clients on the bench would then have the benefit of gigabit access to the server for doing backups but also still have internet access via the server's bridge interface right? Is there a reason I wouldn't want to do it this way?

Re: pxe LiveCD setup
After a very cursory setup, it works! I took notes and will write it up in a bit. The only complaint I have so far is the speed of download via tftp. A 236M ISO took two minutes to load, or about 2M per second. A full CD takes a long, long time. Is that typical, or maybe just the poor Ethernet on this Aspire One D250? I haven't timed them so I can't say for sure. The biggest file I currently use is a windows PE .iso and it does take a bit to transfer. I'll breakout the stopwatch next week and see. My DHCP/tftp server is a Sunfire V240 with Solaris 10. I was having a horrible time with the default tftp server and switched to tftpd-hpa which helped a lot, especially with being able to remap \ to /. Floppy images work well also. I've got a Freedos boot disk floppy image with 3com's universal PXE ethernet driver for dumping and restoring ghost images. Works out of the box with every PXE client I've tried, no need to have custom boot disks with different nic drivers. One of the tweaks I did with the grldr file was to hex edit a section so it goes straight to the menu instead of cycling though the mac address variations. Then I added the company logo to the background of the menu... and ... nobody sees it but me! ___ 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

For example: # zpool iostat tank 2 Later it says about the -v option: You can use the same set of options (interval and count) when examining virtual device statistics. http://dlc.sun.com/pdf/819-5461/819-5461.pdf Page 95 ___ 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
Write attempt to file in ZFS snapshot dir causes panic

I experienced some strange behavior and was wondering if this would warrant a bug report: 1. load zfs from bootloader prompt and then boot. 2. enter fixit environment. 3. import zpool (in this case a 2 disk vmware mirror named sodpool) 4. cd to previously created snapshot at sodpool/test/myfs/.zfs/snapshot/one 5. attempting to create a new file here results in: Fixit# echo hello hello.txt cannot create hello.txt: Read-only file system 6. That seems like the desired response. Next, attempt to modify a file that already exists in the snapshot: Fixit# echo hello test.txt panic: dirtying snapshot!

My settings: /boot/loader.conf: boot_multicons=YES boot_serial=YES comconsole_speed=115200 console=comconsole,vidconsole /etc/ttys: # Serial terminals # The 'dialup' keyword identifies dialin lines to login, fingerd etc. ttyu0 /usr/libexec/getty std.115200 vt100 on secure /boot.config (which is read properly): -Dh -S115200 Anything wrong in the above? Hyperterminal is set to 115200 bps, 8 bits, no parity, 1 stop bit, and no flow control (if that's the correct translation to English). On the serial console, I go from the screen with the FreeBSD logo, with single-user options etc. (which works fine), and then nothing, until a login tty pops up (which also works fine). The main, if not only, reason I want a serial console is to be able to use it for single user mode, DDB, and so on. All kernel messages, and all rc messages are seen only on the graphics card; the serial console receives nothing but the /boot.config: - Dh ..., the logo screen, and then the login screen, during startup and *nothing* at all during shutdown. Also, I'm able to login and use the system both via the serial console and via the graphics card/ keyboard... Is this supposed to be? I'm not complaining, I just got the impression it was one or the other. Any advice on how to get the kernel/rc messages etc. to the serial console (only or as well)? Regards, Thomas Do you use the VGA/vidconsole at all? A serial-only device (think soekris, ALIX/WRAP boards) that has no VGA will have different requirements than a serial-only device will. Your loader.conf statements are different than mine in the definition that you have more than I do to enable serial. My loader.conf just has one statement: console=comconsole - to feed ALL bootloaders, kernel probing, rc startup on the serial device. /etc/ttys defines the login lines. Though trial and error, I found when you use a dual-setup: comconsole,vidconsole, the first one (comconsole) will get rc output, and vidconsole won't. Of course, you're on 8.0 and I don't run BETAs. So the 8.0 BETA might still be having com port oddities, plus I noticed your ttys line is ttyu0, not ttyd0. Did 8.0 change the serial line device? To enable a serial-only device in my setups: /boot/loader.conf: console=comconsole /boot.config: -D /etc/ttys: # enable serial line, cons25 or vt100, depending if I'm originating from a bsd or windows box. Enabling dual-setups should be just the loader.conf change to dual console. HTH (Sorry for the lack of inline replies.) I do have a graphics card, and ideally I'd like to be able to use both, but serial has higher priority (with serial access, I can use minicom on another *nix box and essentially ssh into DDB, and stuff like that - right now I have to borrow a monitor, and write info down manually if needed, turning my head back and forth). I've tried lots of combinations of console=, including simply 'console=comconsole' and/or combinations of that and -D, -h- -Dh and -P in /boot.config. The extra lines in loader.conf are from the handbook, which says they're needed to use comconsole_speed. It seems they do the same thing as -D and -h, though. Oh, and re: /etc/ttys: Yup, it's ttyuX when using uart(4) which seems to be the default now. Actually, since my last buildworld half an hour ago I'm on 9.0-CURRENT. ;) Also, I made sure to set flags to 0x10 for the serial port as per the handbook (although I did it using loader.conf, not the kernel config); before the change, dmesg didn't mention any flags, but it now does. Didn't help squat, though. Though trial and error, I found when you use a dual-setup: comconsole,vidconsole, the first one (comconsole) will get rc output, and vidconsole won't. This doesn't mirror my experience; comconsole and comconsole,vidconsole appears to be just the same for me. I've never gotten anything except the boot loader and a login prompt over to the serial line - at least not at

Re: from very early this morning...
Hi Gary, Just a couple of thoughts, as your setup sounds similar to mine (and a lot of others' I'm sure) - I too recently decided to make a concerted effort to reduce power consumption. I just re-did my file server with FreeNAS and even though I've got tons of hardware laying around I decided to buy the Intel 945GCLF mini-itx board based on the Atom processor, like you find in most netbooks. I put a gigabit NIC in it though as the onboard is 10/100 (but I knew that and already had the NIC). It's running great so far. I'd like to replace my pfSense router/firewall, which is currently powered by an AMD Duron with another mini-itx board that I've had forever, it's one of the Via C3 500 Mhz based boards. It's only got one PCI slot though, which gets me back to the topic at hand. I just changed my network topology when I stood up the new file server. It's now: |-- Wired LAN ADSL Modem -- pfSense | |-- WAP -- WLAN | |-- DMZ (web server) Forgive my artwork. I have my ADSL modem set to bridged ethernet mode which disables all the router/firewall/dhcp features of the modem and just turns it into a media/protocol converter between the phone line and the ethernet cable going to the pfSense box. I use the onboard 10/100 NIC for that PPPoE connection. I've got three more NICs installed to make up the remaining connections. The wired LAN and the WLAN interfaces are bridged. I initially had these as separate networks but most of my media players are wireless and the file server is on the wired side so bridging it was the easiest way (for me!) to get the broadcasts through. The web server is connected directly to the third NIC at the moment and is it's own network. It's still behind the firewall but I can open ports now to it while still protecting the rest of the LAN from the web server if it get's compromised. At least, that's the theory. So that's my setup, don't know if that's the kind of feedback you're looking for but I'd like to hear comments and see what others have going.

What are your requirements for your network ie. are you requiring any fancy trickery, or is this simply trying to NAT a couple of machines behind an ADSL connection?

Re: Monitoring geom
From Michael Lucas' Absolute FreeBSD book page 550: FreeBSD can include a status check of your mirrored disks in its daily periodic(8) run. Just add the line daily_status_gmirror_enable=YES to /etc/periodic.conf. Not sure about other raid types beyond mirrors. On 3/5/09, Mister Olli mister.o...@googlemail.com wrote: Hi hi...
