Reinstallation after boot error

Hello everyone!
I just registered on this forum. I have been using Arch for a couple of months now, it's my first experience with linux so I often land in situations where I'm confused about what to do. I wanted to learn it "the real way", so that's why I chose a dist that's beyond my experience. I've gained a lot of knowledge by just searching this forum and the wiki. I've looked at some threads for my new problem but I'm not sure what to do so I decided to make my own thread. I hope this will not upset anyone.

Anyway, it all started last night. My system went "read only" for some reason. I thought it was wierd, but I figured I'd just restart it and hope for the best. Here's where the problems started. At boot I get similiar errors as in

https://bbs.archlinux.org/viewtopic.php?id=93107

At first I thought I'd test some of the solutions that where given there, but since I'm never very sure of what I'm really doing I thought I'd reinstall Arch again and not risk ruining more than I already have. Should I test print's solution

# root
# mount /dev/sda7 /mnt
# mount /dev/sda5 /mnt/boot
# mount -t proc none /mnt/proc
# mount -t sysfs none /mnt/sys
# mount --bind /dev /mnt/dev
# chroot /mnt
# pacman -S --noconfirm linux-util-ng
# pacman -S kernel26
# reboot

before I go on with the reinstall?

For the reinstall. How should I proceed to loose as little data as possible from my old system? I've put a lot of effert in some websites and configuration files so it would take me a lot of time to do this again. I assume there is some way to only reinstall the parts that are crucial for the system to work? Maybe it's that I accomplish with the solution given above?

I really don't have a clue now and hope some of you could help me out. Maybe I could have posted this in some other thread but it felt better to do a new thread. I hope this isn't breaking any rules.

Just a heads-up:
http://www.archlinux.org/packages/?sort … =&limit=50
There's no linux-util-ng in the repos anymore so you can't use the same commands.

Even if you system is read-only you should be able to copy all the data out of the if you want to reinstall.

Re: Reinstallation after boot error

Ah, ok! Thanks for the reply.

So the smartest thing to do is boot up with the installation media, mount the disks and copy the data I need, then just make a clean install? The problem is that my only other two disks is raided with lvm, not sure if I have to any thing fancy before I could go on?

Not sure if it's just a coincidence, but https://bbs.archlinux.org/viewtopic.php?id=122058 somebody else is having such problem too.

I can't really see the connection between this and that thread hmm Anyways, it seems that the easiest solution for me is to somehow save the data I want and just reinstall Arch.
