There’s nothing much difference in 64-bit installation, the same instructions also works for 64-bit CentOS 6.5 installation, have you tried? RAID 6 is upgraded version of RAID 5, where it has two distributed parity which provides fault tolerance even after two drives fails.
In our earlier article, we’ve seen distributed parity in RAID 5, but in this article we will going to see RAID 6 with double distributed parity. Now, many of us comes to conclusion, why we need to use RAID 6, when it doesn’t perform like any other RAID. Reading will be better than RAID 5, because it reads from multiple disk, But writing performance will be very poor without dedicated RAID Controller.
Note: In the above image depicts that there is no any super-block detected or no RAID is defined in four disk drives.

Narad always believes sharing IT knowledge with others and adopts new technology with ease.
Don’t expect extra performance than any other RAID, if so we have to install a dedicated RAID Controller too. RAID 6 have multiple disks even in some set it may be have some bunch of disks, while reading, it will read from all the drives, so reading would be faster whereas writing would be poor because it has to stripe over multiple disks. Hmm… those who raise this question need to know that, if they need high fault tolerance choose RAID 6.
Before creating a RAID drives, always examine our disk drives whether there is any RAID is already created on the disks. After creating partitions, it’s always good habit to examine the drives for super-blocks. You can also check the current process of raid using watch command as shown in the screen grab below.
Create some files under mount point and append some text in any one of the file to verify the content.
It is possible to add a spare drive while creating our RAID set, But I have not defined the spare drive while creating our raid set.
Now again confirm the new attached disk for any raid is already configured or not using the same mdadm command. Now, let us check whether spare drive works automatically, if anyone of the disk fails in our Array.


It’s highly recommended to go through release notes as well as the upstream technical notes about the changes before an installation or up-gradation.
It’s alike RAID 5, but provides more robust, because it uses one more disk for parity. Here in RAID 6 even if we loose our 2 disks we can get the data back by replacing a spare drive and build it from parity.
In every higher environments with high availability for database, they use RAID 6 because database is the most important and need to be safe in any cost, also it can be useful for video streaming environments. Here, we will show how to create partition on sdb drive and later same steps to be followed for rest of the drives. In some cases, if any one of the disk fails we can get the data, because there is double parity in RAID 6.
Do we have to add it in Raid or can we attach it directly and convert it into pv then extend vg..
