Partition Recovery Course - md-raid Test

If one of the array disk has a damaged superblock how you can fix it?

copy a superblock along with all GPT table from a healthy disk and edit a role for the disk with damaged superblock
just copy a superblock from a healthy disk
copy a superblock along with all GPT table from a healthy disk

If you know that array member disks, say in RAID 5, are all of the same size, then

md superblocks are located at the same offset in the end of the disks
md superblocks are located at the same offset either in the beginning or in the end of the disks depending on superblock version
the disks will use the same partition layout
md superblocks are located at the same offset in the beginning of the disks

md-raid allows to create arrays without superblocks at all

rue
false

Superblock can be located after data

true
false

How the number of a disk in the array is called in md-raid?

disk identifier
disk function
role

The main component of md metadata is

i-node
GPT or MBR table
header
superblock

Why earlier superblock versions can give you more information about a RAID?

because when NAS detects a disk failure, it no longer updates superblocks on them
because such superblocks are typically written to safe place
because such superblocks are typically not affected by a rebuild

Superblock is always located before data

true
false

What is the difference between 1.x versions of md superblock?

superblock format
superblock configuration
superblock location

The superblock part describing an array is

the same only on first and the last disks
the same on all array member disks
different on each array member disk
