Root on LVM bug
Greetings, I recently installed etch on an amd64 box which previously had Fedora. It had a small ext2 /boot and large LVM, so I shrunk Fedora's volume and made a new one for Debian, where I installed everything. I included the LVM modules in /etc/initramfs-tools/modules . Then I added the following section to /boot/grub/menu.lst : title Debian root (hd0,0) kernel /vmlinuz-2.6.18-4-amd64 root=/dev/VolGroup00/LogVol02 initrd /initrd.img-2.6.18-4-amd64 When I booted, it sat at Begin: Waiting for root file system... but the Fedora 2.6.11 kernel started right up with otherwise identical options (except that it couldn't load the Fedora modules in Debian). After a few hours of messing around, on a whim I tried changing the root= parameter to /dev/mapper/VolGroup00-LogVol02 , which worked! So I believe something is wrong with either mount or udev used in the initramfs, such that it either doesn't create the /dev/groupname entries, or can't mount them. I did a ton of searching and couldn't find anything, so I don't think this is a known issue. Given that installed Debian and other distros can use both /dev/mapper and /dev/groupname, shouldn't this be supported in the root= parameter in grub? Where is the bug, and has it been fixed already in lenny? If not, how can I help?
