Ok, so my Ubuntu 12.10 install seems to have gone slightly sideways. It currently boots from a Compactflash card that I was planning on replacing soon, but as luck would have it it's gone down now. The boot process gets to a certain point and then just sits there, and if I boot up a distro off a flash drive and then mount up the LVM partition, the live distro freezes after a couple of minutes. Now I'm not averse to installing and starting again, but I would love to pull off all my config files etc (all user data is stored on a separate ZFS pool).
Is it worth me trying to fsck the drive first, or am I better off avoiding doing anything more to it?
If so, how about importing the ZFS pool and then DDing the filesystem to an image on the pool? That way I'll be able to gain access to it.
