I’ve been having hardware issues with my Fedora 20 installation (yes, I know it’s still beta until tomorrow). I had it on a new WD 2T drive, but occasionally I was having boot problems, and having to repair the filesystem. I noticed that it was making strange noises and running hot, and taking a long time to even get to GRUB, indicating that it was hanging up the BIOS itself. I was on the verge of returning it, when I tried moving it from the first to the second SATA interface on the MB (I have six). The problems went away, so apparently it’s a motherboard problem on that interface (at least that’s what I’m inferring). Unfortunately, it refuses to boot now, dropping into emergency mode, and telling me that it can’t switch root, because /sysroot/etc/os-release is missing (which it does seem to be). I tried copying /etc/os-release to /sysroot/etc/os-release, but it wouldn’t let me (and etc doesn’t seem to currently exist on /sysroot).

Any ideas how to fix this?

[Update a few minutes later]

Apparently Anaconda can’t be bothered to load logical volumes before looking for linux partitions. But why?

And what do I do about it? When I do a ‘vgchange -ay’ it loads them, but if I then run anaconda, it still doesn’t work, and when I go back to shell, they’re no longer mounted. I can’t believe I’m the only person having this problem, but I’ve done searches and can’t find any useful information about it.

Someone on twitter asked me to post the contents of grub.cfg, so here it is, after the fold:
