Partition Recovery Course - md-raid Test

Where are copies of superblock stored?

on each array disk either in the beginning of the disk or in the end
only on the first member disk in the end
on each array disk always in the beginning
only on the first member disk in the beginning

The superblock part describing an array is

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

Superblock includes two significantly different parts; one describes a RAID and other – a specific disk

true
false

When recovering md how you should sort superblocks?

by size
by relevance
by generation number

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

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

Superblock can be located after data

false
true

In what devices md-raid is commonly used?

Windows Servers
DASes
NASes

Check what can be designated as "md"

driver
software RAID metadata
NASes using Linux
disks from a NAS

The main component of md metadata is

header
superblock
GPT or MBR table
i-node

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

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