Robert's comment prompted me to try this on my home server which runs 7-STABLE, but which I will probably upgrade to 8-STABLE in a few months time. What I did was: 1. Replace 'device sio' with 'device uart' in the kernel configuration file. 2. In /etc/ttys change all ttydX to ttyuX, where X was 0 to 3 in my case. 3. In /boot/device.hints change all hint.sio.X.Y to hint.uart.X.Y I then rebooted with my fingers crossed since said machine is headless. I need not have worried since it worked first time. If anyone thinks I forgot something please _do_ speak up.

If you have both sio and uart in your kernel (the default on 7.x IIRC), sio will take precedence. N.B: please exercise caution when doing this to a server in a colo 1 km away. :) ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"

Could you briefly elaborate on how that's done with 7.x? I.e. is changing device.hints and /etc/ttys enough (what changes?), or do I need to recompile the kernel? (I'm a bit confused because both uart and sio seem to be in GENERIC, but I haven't been able to active uart through device.hints. I couldn't find anything on freebsd.org or the internets, either.)

The binary upgrade from 7.1 -> 7.2 went without any problems. I didn't bother to switch to single user mode. I did however stop some critical services in /etc/rc.conf before starting the upgrade. The reason why I didn't go to single user mode was that my /usr and /var were not mounted in single user. I had only /. I wasn't sure how to deal with that. Anyway, all is fine and I have a fresh 7.2! Thanks again all of you!

I've seen the instructions here: http://www.freebsd.org/releases/7.2R/announce.html I've heard that it's safest to start the machine in single user mode when doing upgrades, but I see no notice about it in the announcement. So my question is: Is it ok to do this binary upgrade without start single user mode first? If no, must I reboot my machine to enter single user mode? I always did upgrade in multiuser for minimalising the downtime of servers. I always do it this way, but accept the risk involved. I actually did my 7.x -> 8.x upgrade on my web/shell server this way, with users logged in, but I think that's probably only for the brave of heart. FWIW, the main problem I ran into with my 8.0 upgrade is that 8.0 uses the uart(4) driver for serial ports, and sio(4), 7.2's default, has been removed. They require mutually exclusive lines in device.hints and different /etc/ttys lines. If you rely on a serial console, I would recommend first switching 7.2 to using uart, pausing for a bit, and then switching forward to 8 so that you separate the risks associated with changing console drivers from those associated with sliding a major kernel version.

The announcement explicitly points to the FreeBSD Handbook for the procedure for doing source upgrades, which does indeed including booting the new kernel into single-user mode before doing the installworld. > So my question is: Is it ok to do this binary upgrade without start > single user mode first? Sure. It's riskier; if the new kernel doesn't boot, but you already have the new userland installed, you're stuck. You'll need to recover from some other bootable media, which may well take quite a while. Just how risky it is depends on how big a version jump you're making. > If no, must I reboot my machine to enter single user mode? Rebooting is at least as important as getting into single-user mode. You want to know your kernel is good. Single-user mode is good, too, because you don't want to change utilities out from under running processes if you can help it. All of that said, though, I do it all the time on lightly loaded machines. I always reboot after completing the upgrade, and usually also in between the installkernel and installworld. Trying the upgrade on a test machine first helps reduce the risk as well. Unfortunately, machines that you want to avoid downtime on are usually the same ones that you really can't afford to fail an upgrade... ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
