What information is found in the following excerpt from the file /proc/mdstat? (Choose two.)
A.
One of the disks in /dev/md0 has failed and a spare disk is used to recreate full redundancy
B.
The spare disk /dev/sda1 is used to restore full redundancy after the current recovery
C.
The information [UU_] means, that the raid is missing one disk and is not fully redundant
D.
The device is using version 1.2 metadata to allow LILO and GRUB Legacy to use /dev/md0 as the boot partition. This would not have been necessary with GRUB2
E.
The information [3/2] means that 3 RAID disks belong to the array and 2 disks are spare. Together they equal the number of available disks
It is A, C and E. A is correct, because we see a ongoing recovery process. C is correct, because [UU_] indicates two active disks and one missing, so nu full redundancy. E Is correct, too, since the notation of [3/2] is saying that this RAID 5 has three active disks and 2 spare disks.
