Re: grub and rootfs as LVM
I don't know: it just works. As long as you have the lvm2 package installed and the initrd package was created after the lvm2 package was installed, it should just work. Hi Stefan, After I changed root device to /dev/mapper/volume-root, Linux boots successfully. And I didn't make anything special for LVM when creating initramfs. Thank you very much. Stefan
Re: grub and rootfs as LVM
I setup /boot as a seperate disk parition. The rest is for LVM. /dev/volume/root is OK when I use a rescue CDRom. And I re-build the initrd, adding all dm-* modules to the initrd. Any suggestion? Try use /dev/mapper/volume-root instead. I'm not sure why, but I recently had a similar problem where using /dev/Debian/root didn't work but /dev/mapper/Debian-root did (even though once the boot is over, /dev/Debian/root can be used just fine, it looks like the alternate name is constructed later). Hi Stefan, Would you please tell me how to create a initrd with LVM support in Debian? I used the initramfs tool. Thank you very much!

grub and rootfs as LVM
Dear all, I setup my rootfs as an LVM, the menu.lst of grub looks like this; title Debian GNU/Linux, kernel 2.6.18-4-386 root(hd0,0) kernel /vmlinuz-2.6.18-4-686 root=/dev/volume/root ro initrd /my_init savedefault Error happens when the kernel tried to mount the root filesystem: The error message is Waiting for root file system... yuwen check root=bootarg cat /proc/cmdline or missing modules, devices; cat /proc/modules ls /dev/ I setup /boot as a seperate disk parition. The rest is for LVM. /dev/volume/root is OK when I use a rescue CDRom. And I re-build the initrd, adding all dm-* modules to the initrd. Any suggestion? Best regards, Yuwen

I fell into a busybox command. There's no dirs in /dev/mapper, only control: ls /dev/mapper control What is control?
