Re: lost network during freebsd-update install
at this stage, i have no remote access. even if i could gain access, i wouldn't know what state it's in or how to proceed. it's probably best now to pay for the hosting company to install 8.1 from cd.

Rollback does work, and has worked for me in a very similar situation, and hopefully will work for you as well. After the rollback, reboot, and start again from your initial upgrade command. I would highly recommend using tmux, and also installing a remote console/management card for your system so you can control it remotely.

On 03/10/2011 04:24 PM, Tom Worster wrote: before resorting to cd. Hi, I've read your last post, this sucks. I missed a point which you have thought about (see below) The best thing would have been either rollback or reboot and continue, see below. the handbook describes a procedure: A) 1st freebsd-update install: The kernel and kernel modules will be patched B) reboot C) 2nd freebsd-update install: The state of the process has been saved and thus,freebsd-update will not start from the beginning, but will remove all old shared libraries and object files i'm just guessing...

A) did complete while i was disconnected. when i repeated freebsd-update install it attempted C) but because the old kernel was still running it didn't work and started dumping cores all over the carpet. result: system hangs attempting to start some userland part. I guess you're right here. When ssh disconnects the shell does not immediatly exit, it takes some minutes. So freebsd-update succesfully installed the kernel and when you got connected again and ran install the second time it tried to install a new userland on top of the old running kernel which in case of this major version upgrade did not work. Why so much stuff is missing though is not clear to me, I would think that freebsd-update just overwrites the old binaries. it seems a pity now that freebsd-update chose to use the same command verb for both A and C. It would be nice if freebsd-update had the same command sequence (without the build parts) as in a source upgrade. First fetch of course, then freebsd-update installkernel with a message to reboot on succes or rollback on failure, then after reboot freebsd-update installworld, with a check if the new kernel is actually loaded, after that and rebuilding ports freebsd-update delete-old-libs I would like to know how others think about this approach, or am I thinking completely wrong here? real hw. i'm considering going to the clouds. i could easily restore from a vm snapshot. but for that i need to learn linux, another big time sink. add votes here: http://feedback.rackspacecloud.com/forums/71021-product-feedback/suggestion s/989519-create-a-freebsd-image Voted.
