Hello. Last week, I installed Archlinux-i686-2007.08-2.ftp.iso on my system. I'd like to have / on /dev/sda3 (PATA) and /usr on /dev/sys/ArchUSR. "sys" is a LVM2 Volume Group, which I also use in my Gentoo Linux installation on the same system. I've read some installation guides on the Arch Wiki and changed USELVM=YES in /etc/rc.conf and have this in mkinitcpio.conf: HOOKS="base udev keymap autodetect pata lvm2 filesystems" After changing that line, I re-ran mkinitcpio and a new img was created; this image is loaded through grub; menu.lst has: title Arch kernel (hd0,2)/boot/vmlinuz26 root=/dev/sda3 initrd (hd0,2)/boot/kernel26.img In /etc/fstab of the Arch installation, I've got: /dev/sda5 swap swap defaults proc /proc proc defaults usbfs /proc/bus/usb usbfs defaults sysfs /sys sysfs defaults udev /dev tmpfs defaults,size=8m devpts /dev/pts devpts defaults devshm /dev/shm tmpfs nodev,nosuid,noexec temp /tmp tmpfs defaults /dev/sda3 / ext3 noatime 0 2 /dev/mapper/sys-ArchArch /Arch ext3 noatime 0 2 /dev/sys/ArchUSR /usr ext3 noatime 0 2 When I boot the system, I see that the "sys" VG gets activated and fsck.ext3 is run for /dev/sys/ArchArch and /dev/sys/ArchUSR (messages to the effect that such-and-such fragmentation exists shows and before that, something like LVM [done]). BUT: I can't boot. Booting stops with: mount: special device /dev/mapper/sys-ArchArch does not exist mount: special device /dev/sys/ArchUSR does not exist This shows, that both "paths" are not accessible; neither the /dev/sys/* stuff (which on a Gentoo Linux installation contains symlinks to /dev/mapper), nor the "proper" /dev/mapper path can be accessed. Any ideas about why that happens, and, more importantly, how to fix that? Thanks a lot, Michael
