Root on lvm
I am in the process of building a two node cluster.
Based on gentoo (mainly for the extensive customization)
I decided to use LVM for everything except /boot
Currently I decided to use 5 partitions on a 80GB disk
/dev/sda1 /boot 32mb
/dev/vg/swap 12GB
/dev/vg/root 4GB
/dev/vg/data 21GB
/dev/vg/drbd 21GB
The issue now is that when I try to boot I get a kernel panic with the error:
VFS: unable to mount root fs on unknown block (0,0)
I compiled the kernel with LVM support and added dolvm to the kernel line in grub.conf
I read something about needing to create an initramfs with lvmcreate_initrd, but could not find it.
I have a log of all the steps I took during the install (it isn't really clear, since it is mostly for personal reference)
grub.conf:
Code:
