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/sda1and /dev/sdb1. After looking at the status of the RAID 1 array in the /proc/mdstatfile, the administrator discovers the RAID 1 array is degraded and the disk /dev/sdb1on which the database application was installed appears to have failed.

Which of the following steps should the administrator take to remove the device /dev/sdb1from the RAID array md0? (Choose two.)

• A.racadm --remove /dev/sdb1
• B.mdadm /dev/md0 --remove /dev/sdb1
• C.mdadm /dev/sdb1 --fail /dev/md0
• D.racadm --fail /dev/sdb1
• E.mdadm /dev/sdb1 --remove /dev/md0
• F.mdadm /dev/md0 --fail /dev/sdb1
