That wasn't quite right. Amazingly, mullender.c works unmodified
on 4.3/vax. Using simh-pdp11 and
www.tuhs.org/Archive/PDP-11/Boot_Images/{2.9BSD_rl02_1145.gz,README}
confirms that the output was the same on both machines.

Re: Pre-Order Prizes
2009/3/2 new_guy byte8b...@gmail.com I mentioned this when I pre-ordered 4.4... I think folks thought that I was joking. Do prizes for pre-orders. Nothing fancy just something like this: 1.

Since there's no special format for raid1, as a last resort you can adjust the disklabel location and change the type to ffs, then mount it normally without going through softraid. scanffs can probably make this easier.

3Qs, including How insane to have /var mount with softraid discipline raid 1 ?
#1 In a real world for small non-profits, in many cases, its what was left over or donated, so question one, does the softraid, bioctl, have to much heartburn if the drives are not the same geometry... I've always used matching drives for raid of anytype, but even $60*2 for two drives is a stretch for some nonprofits these days #2 And the next question in the subject, thinking about which mounted partition changes the most frequently through the day that would be /var The others, /usr for example don't change as much and could be rsync or tgz nightly...or weekly however... perhaps /home and /tmp, but definitely /var. could change significantly during the day. For example the log files, /var/mail, /var/mysql and so on are active. I wander about /var/mysql and ldap being on a softraid.? How insane would it be to use the new softraid features for all of /var to make a mirror raid 1 of say 3 drives and then dump and restore the orig. /var to that softraid and change /etc/fstab for /var to use it? #3 Of note, as I understand (might not documented in man yet) if one or two of the three raid1 partitions making the volume fails, it will keep running but cannot be rebuilt... To 'rebuild' means dumping the volume, in this case /var with say 'dump' may be best over pax/tar and then making anew a softraid and restoring the dump. But what happens if the computer reboots with say the third drive missing the power cable? and it runs for a day or so, then tech reboots with molex plug put back it? does the softraid catch the third drive up? This is something I guess I could test myself, just asking. tia.

disk perfomance issues with Symbios Logic MegaRAID SAS 1064R and mfi driver
Hello, Some what of a novice openbsd user and hope I didnt miss something obvious. I have a box running openbsd 4.2 which I cannot upgrade for various reasons. The machine has the Symbios Logic MegaRAID SAS 1064R controller and currently has a 4 disk Raid5 set up in bios with Seagate ST9146802SS disks. We also run the same machines with Linux and openbsd 4.2 with older hardware using an Ultra Scsi controller. Anyway we have some basic tests we run and noticed that a basic Bonnie++ test on all 3 machines gave the following performance numbers. Openbsd 4.2 and Symbios SAS 6073 K/sec Block Seq Output and 83086 K/sec Block Seq Input Linux RH 7 and Symbios SAS 65096 K/sec Block Seq Output and 165194 K/sec Block Seq Input Openbsd 4.2 and Adaptec SCSI 30849 K/sec Block Seq Output and 36291 K/sec Block Seq Input Now I wouldnt expect the numbers to match exactly given a number parameters but the 6073 K/sec Block Seq Output is somewhat of a concern. Since it doesnt seem to affect Linux using the exact same hardware I think its most likly a driver and or configuration issue. So does anyone know if there are issues with the mfi driver or any configuration bits within openbsd I might be missing with regaurds to disk performance? Here's the exact line from syslog if thats of any help: Feb 18 19:45:33 /bsd: mfi0 at pci4 dev 14 function 0 Symbios Logic MegaRAID SAS 1064R rev 0x00: apic 8 int 18 (irq 5) Feb 18 19:45:33 /bsd: mfi0: logical drives 1, version 5.1.1-0038, 128MB RAM I will note that we needed to apply a driver patch to recognise this card in 4.2 but that was simply to add the pci device type to the list of other supported types. I am unaware of any other changes. thank you for your time -denis -- __ Denis Alan Hainsworth de...@alumni.brandeis.edu

Re: Dual-port gigabit PCI card options

OpenBSD PCI wireless card (for bridge)
Hi all! I've got an Intel server that I would like to turn into a wireless bridge. I'd be using OpenBSD 4.4, and I'm asking for recommendations on the wireless end. Is there a PCI (not PCI-E) card that would be well supported and provide good range? I'm looking for 802.11b/g. Anything else is nice, but not needed. Or perhaps would PCI not be the way to go (i.e., USB, something else I haven't considered)? I have a SOHO wireless bridge, but I hate it (and I can't install OpenWRT or anything NICE on it). I'd like to get to know PF and OpenBSD a lot better, and this seemed like a good project. Thoughts? - Jon
Re: disk perfomance issues with Symbios Logic MegaRAID SAS 1064R and mfi driver
I think I have to conclude that you (or your hardware) are doing it wrong. Either you have interrupt issues or your raid card setup wrong. I also have no idea how you measured these numbers so I can't deduce any validity from them.

Re: 3Qs, including How insane to have /var mount with softraid discipline raid 1 ?
#1 no #2 i use softraid for all kinds of uses; nothing you mention here is odd or out of place #3 that is correct; the lazy author still hasn't finished partial bringup and rebuilds. that guy kind of sucks and needs to be reminded often to get off his lazy slack bum butt.

I've always used matching drives for raid of anytype, but even $60*2 for two drives is a stretch for some nonprofits these days #2 And the next question in the subject, thinking about which mounted partition changes the most frequently through the day that would be /var The others, /usr for example don't change as much and could be rsync or tgz nightly...or weekly however... perhaps /home and /tmp, but definitely /var. could change significantly during the day. For example the log files, /var/mail, /var/mysql and so on are active. I wander about /var/mysql and ldap being on a softraid.? How insane would it be to use the new softraid features for all of /var to make a mirror raid 1 of say 3 drives and then dump and restore the orig. /var to that softraid and change /etc/fstab for /var to use it? #3 Of note, as I understand (might not documented in man yet) if one or two of the three raid1 partitions making the volume fails, it will keep running but cannot be rebuilt... To 'rebuild' means dumping the volume, in this case /var with say 'dump' may be best over pax/tar and then making anew a softraid and restoring the dump. But what happens if the computer reboots with say the third drive missing the power cable? and it runs for a day or so, then tech reboots with molex plug put back it? does the softraid catch the third drive up? This is something I guess I could test myself, just asking. tia.

Delaying BGPD Failover
Hi Misc@, I got 2 internet upstream providers, 1 is main and another is backup. I'd like to ask has anyone had experience to setup a measured failover time using either holdtime or keep-alive parameters. This is because of my main upstream bgp router is oftenly restarted (twice a week now), and yes their not using OpenBGPD. I'm thinking to delay fail-over sequence from 5 to 15 minutes. If its not possible, then I'll go with scripts and cron. Thanks, -- insandotpraja(at)gmaildotcom
