I've never been able to install a working copy of Linux on my PC, so I don't know squat. Linux cannot use the disks on my ATARAID controller, even though it says on the box that the controller supports Linux. Using the proprietary driver, I can't recompile the kernel with eg. appropriate sound card drivers and the open source ATARAID driver isn't up-to-date with the metadata format. I'm trying again now that DM and DMRAID has arrived, but (as is probably apparent), I haven't got a clue what I'm doing :-) >> Any hints on what is going wrong / what I am doing wrong? > > The Device-Mapper mirroring target is called "dm-mirror".

Gerte, is there somehow that I can persuade you to build a new LiveCD with dm-mirror support? I would like to do it myself, but am a bit stuck since no Linux distro will install on my PC :-/.. -- dm-devel mailing list dm-devel@redhat.com https://www.redhat.com/mailman/listinfo/dm-devel
