being new with this topic I followed the instructions in http://www.eclectica.ca/howto/openbsd-software-raid-howto.php
Everything worked until I tried to mount /dev/raid0a /mnt (for changing the entries for the disks in /etc/raid0.conf) I got the message device busy so I changed the entries in /etc/raid0.conf manually on both disks. I could reboot from the raid. However raidctl -s raid0 tells: raid0 Components: component0: failed /dev/wd1d: optimal No spares. Parity status: DIRTY Reconstruction is 100% complete. Parity Re-write is 100% complete. Copyback is 100% complete. What do I have to do to get a working raid1 configuration in this situation? Harry
