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] sdb5[2](F)
297088 blocks [2/1] [_U]
unused devices: <none>
[root@server1 ~]#
Which two statements are true? (Choose two.)
A.
The RAID array is destroyed because one disk partition has failed and the entire data on the
disk would be lost.
B.
The RAID array could be restored back to the high availability state using a new RAID disk
partition replacing the faulty one.
C.
The RAID array would not synchronize with the newly created files and directories after the
failure, even if the array is re-created.
D.
The faulty RAID device, /dev/sdb5, could be replaced with a new RAID disk partition and RAID
array would be regenerated with the new disk partition after synchronizing with the /dev/sdb6
RAID disk.
