Hi All, We have a Debian 3.1 Sarge Stable running on a backup server. The server has 5 Harddisks, two IDE and Three SCSI. When we manually form the RAID array with the mdadm command , do an mkfs.ext3 on the array and then mount the array ( /dev/md0) on /backup every thing is fine. But when a restart is done, the raid array is not formed. How can i initialize the Raid array formation at boot up? While installing mdadm , i did say yes to auto-start it. -- TAC Support Team
