Well, no, I do a regular shutdown with shutdown -h now, or reboot for rebooting. I have it working now however. I think what was wrong is that I had my /etc/fstab like this: # <fs> <mountpoint> <type> <opts> <dump/pass> /dev/sda1 /boot ext2 noauto,noatime 1 1 /dev/sda5 / xfs noatime 0 0 /dev/dsa2 none swap sw 0 0 /dev/md0 /raid xfs noatime 0 0 /dev/cdroms/cdrom0 /mnt/cdrom iso9660 noauto,ro 0 0 proc /proc proc defaults 0 0 tmpfs /dev/shm tmpfs defaults 0 0 I did not have the fschk option (the last one) set to 1 on /dev/md0. At least someone advised me to do so, so I set it to 1, tried to reboot and it works just fine now ;) (here is the thread of this help: http://forums.devshed.com/t101414/sd5d6d3f616a474180753071f3ce364ef.html ) I still would like to understand WHY this helped, could you explain? Another question: How do I restart "from scratch", reformatting the drives does not earase the persistent-superblock etc.... And last one: Now that the RAID is setup (which is not holding the OS, it's purely used for storage), I would like to use another disk for the OS. So after I install Linux on another disk, can I just mount the RAID afterwards?
