Hi, After another day of investigation I found that both /boot and /root have to be on RAID array with metadata 0.90 (at least for LILO). So now I have: md1 - (sd{a,b}1 - boot) md2 - (sd{a,b}2 - root) md3 - (sd{a,b}3 - LVM) Another thing I have found is that system doesn't add md3 automatic, so LVM is not initialize nor partition on it. I had to add /sbin/mdadm --assemble - scan to /etc/rc (line 16 - before device-mapper nodes creation) Before I'll update Wiki I would like to ensure that may finding are correct.
