As far as I know, there is no "automatic conversion tool" for most of these. Switching from non-raid to RAID-1 (mirroring) is the only one I think that might work. > >> I want to do it this way because I don't trust LVM enough to put my OS > >> on.

If I was a guru on it, I might feel better about it. Worst case I had: the metadata was incorrect. This was back with 2.6.18 kernels though. That was also easily recovered as all the LVM-tools, with default configuration, backup the metadata to a text-file before/after making any chances. You can then easily recover if anything goes wrong :) > > Please note, I have not lost data related to issues with LVM.
