I managed to set up 8 raid1 mirrors and everything is working fine. The raid-Howto was a great help for me but I am missing some hints what to do in case of - a disk of my raid1 mirror fails - there is a power failure and the mirrors may be in an inconsistent state. There is a section "Error Recovery" in the old Software-Raid Howto but I guess most of it is out of date. I want to have some clear guidelines what to do in the "worst case", especially since I would have to fix the problem as soon as possible and I hate to work under pressure. Thanks for any hints, Werner
