A Linux administrator receives a call from the network operations team that one of the database applications is down on a Linux server. The Linux server is configured with RAID 1 for redundancy, and the array /dev/md0 consists of two devices called /dev/sda1 and /dev/sdb1. After looking at the status of the RAID 1 array in the /proc/mdstat file, the administrator discovers the RAID 1 array is degraded and the disk /dev/sdb1 on which the database application was installed appears to have failed.
