Partition Recovery Course - md-raid Test

Check methods which can be used to determine a role for a disk

do entropy analysis, if RAID5
guess
do parity analysis, if RAID5

Superblock is always located before data

false
true

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 beginning of the disks
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

The superblock part describing an array is

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

The main component of md metadata is

i-node
header
superblock
GPT or MBR table

In what devices md-raid is commonly used?

NASes
Windows Servers
DASes

md-raid can consist of other mad-raid arrays

false
true

The superblock part describing a particular disk is

the same on all array member disks
the same only on adjacent disks
different on each array member disk

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

What is the difference between superblocks among array member disks?

the copies of superblock are identical between array member disks
information about a particular disk
