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.
Feel free to update my article (mark the LVM specific changes) or create a new one. I cannot really assist you further since I never used LVM and I have no idea how LVM deals with RAIDs. Did you test the RAID by hot-plugging a harddisk (SATA is usually no problem) and rebooting the computer? LILO has to boot from each disk, no matter which one failed. A new spare disk also needs LILO installed in the MBR... Regards, Clemens
