Partition Recovery Course - md-raid Test
md-raid allows to create arrays without superblocks at all
Superblock is always located before data
Check methods which can be used to determine a role for a disk
do entropy analysis, if RAID5
do parity analysis, if RAID5
When recovering md how you should sort superblocks?
by generation number
How the number of a disk in the array is called in md-raid?
The main component of md metadata is
GPT or MBR table
Why earlier superblock versions can give you more information about a RAID?
because such superblocks are typically written to safe place
because when NAS detects a disk failure, it no longer updates superblocks on them
because such superblocks are typically not affected by a rebuild
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 either in the beginning or in the end of the disks depending on superblock version
md superblocks are located at the same offset in the end of the disks
the disks will use the same partition layout
Superblock includes two significantly different parts; one describes a RAID and other – a specific disk
In what devices md-raid is commonly used?
