I'm successfully running a SIL 3112 dmraid mirrored configuration since months, but I have just recently started using the mirror from Windows. I started out using a home-brewed initrd setup on linuxfromscratch and then switched to gentoo using gerte's excellent livecd and init scripts. Now, each time I boot linux after having run a Windows (XP) session, the device names have changed! I can manage to get everything up and running by using the provided shell and figuring out the new boot device name, then fixing fstab and grub.conf afterwards. I have found out that the sil incarnation_no seems to increase by two everytime I run Windows. What is the incarnation_no used for, and why is it used to create the device name? /Erik
