Most FAQs advise you to partition your disk. But my PV is about 5TB, which stupid DOS partitioning can't handle anyway. I think it should be possible to have a small LV containing the /boot directory. With my PE size of 32M, I don't even have to worry if it is contiguous, as it will fit into a single PE. The very first sector of a PV seems to be unused by LVM, thus a Lilo or Grub MBR may be installed. The remaining problem is to set up the mapping for LILO or Grub to load further stages and the kernel itself. I looked into the LILO sources and indeed found some fragments dealing with LVM when trying to get the physical sector numbers of the files to load (using FIBMAP). But I'm still searching where this is documented. The Grub development seems to be focused mainly on wired mutiboot problems with DOS and Windows XY. The whole system fundamentally depends on the concept of a partition table to solve problems I will never have :-) Dieter.

My thanks to everyone for = answering.

From the lilo author, I found that my choices are for = “/boot” to either be on RAID-1 or to be under LVM. But both are not = allowed.

So I am considering what to do = next.

What is the state of the LVM mirroring code? = Could I create mirrored logical volumes in LVM rather then putting LVM on top of = RAID-1 md?

Thanks!
