Why is new raid 5 build 'recovering'?

view full story

http://askubuntu.com – I am building a home server with raid 5. I first set up the system to boot from compact flash. After i got that working I tried to create the raid 5 array. All disks are new and have no data on them. I used the following command to create the array: mdadm --create --verbose /dev/md0 --level=5 --raid-devices=3 /dev/sd[bcd]1 After this I ran 'watch cat /proc/mdstat'. The system is recovering - very very slowly (like 40 hours to recover). How do I tell the system these are new disks with no user data on? I don't want to recover anything. (HowTos)
