What information is found in the following excerpt from the file /proc/mdstat? (Choose two.)
What information is found in the following excerpt from the file /proc/mdstat? (Choose two.)
The excerpt from /proc/mdstat provides information about the current state of RAID arrays and their configurations. The option describing a disk failure and the use of a spare disk for recovery is correct because the excerpt indicates an active recovery process. The information [UU_] marks that the RAID array is currently missing one disk and is not fully redundant, as a fully redundant RAID 5 array would typically display [UUU]. Thus, the correct answers are: one of the disks in /dev/md0 has failed, and the information [UU_] means that the RAID is missing one disk and is not fully redundant.
A, C - 100%
A, C - OK
A, C - OK
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.
