You can do this, but if you want to use a linux software raid as ROOT (/), you must use raid-1, or create one single partition for /boot. this is a limitation of grub/lilo to access the kernel and initrd images. > >DRBD would access /dev/md0, and there are LV's / and swap on /dev/md1.

Does you realy need to use LVM ? i have bad experiences with it, like having some problem with my lvm volumes, sending 300 GB of files in lost+found. i never had problems with software raid. :-D > >What do you think of this? > >Nate -------------- next part -------------- An HTML attachment was scrubbed...
