The correct answer is B. The RAID array could be restored back to the high availability state using a new RAID disk partition D. The faulty RAID device, /dev/sdb5, could be replaced with a new RAID disk partition and RAID. See the full explanation below for the reasoning.
Question
You have the redundant array of independent disks (RAID) device /dev/md0 mounted on /data to store some critical system files. While watching the /var/log/messages log file, you found the following kernel log message: Apr 25 22:09:59 server1 kernel: raid1: Disk failure on sdb5, disabling device. Apr 25 22:09:59 server1 kernel: Operation continuing on 1 devices Apr 25 22:09:59 server1 kernel: md: md0: sync done. You opened the /proc/mdstat file to check the RAID statistics as shown below: [root@server1 ~]# cat /proc/mdstat Personalities : [raid1] md0 : active raid1 sdb6[1] sdb52 297088 blocks [2/1] [_U] unused devices: <none> [root@server1 ~]# Which two statements are true? (Choose two.)
Options
- AThe RAID array is destroyed because one disk partition has failed and the entire data on the disk
- BThe RAID array could be restored back to the high availability state using a new RAID disk partition
- CThe RAID array would not synchronize with the newly created files and directories after the failure,
- DThe faulty RAID device, /dev/sdb5, could be replaced with a new RAID disk partition and RAID
