00:00.000 --> 00:02.480
Okay, so here is the validation challenge.

2
00:02.480 --> 00:06.360
The very first thing the type I'd like you to do is to add two new hard disks

3
00:06.360 --> 00:08.000
to one of your managed devices

4
00:08.000 --> 00:10.680
and ensure that they are of the same size.

5
00:10.680 --> 00:14.850
Next, I'd be going to create a playbook that is going to construct a straight

6
00:14.850 --> 00:16.600
read array using these hard drives

7
00:16.600 --> 00:20.000
recall straight correlates to a very particular rate level.

8
00:20.000 --> 00:23.780
So give it a think and make that correct configuration and then give the array

9
00:23.780 --> 00:25.280
an XFS file system

10
00:25.280 --> 00:29.280
and then use the playbook to create and mount the file system in a directory

11
00:29.280 --> 00:32.160
called forward slash mnt forward slash
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

11
00:29.280 --> 00:32.160
called forward slash mnt forward slash

12
00:32.160 --> 00:37.280
validate hyphen read and ensure that the file system is going to be immediately

13
00:37.280 --> 00:39.800
mounted and will automatically mount

14
00:39.800 --> 00:41.400
when the system is rebooted.

15
00:41.400 --> 00:45.100
Then lastly, I wanted to create a playbook to check that there are no failed

16
00:45.100 --> 00:46.680
devices in the read array

17
00:46.680 --> 00:52.080
and this playbook should print a message specifying whether the test passed or

18
00:52.080 --> 00:54.240
whether the test failed for each device.

19
00:54.240 --> 00:57.150
So give it a think but of your terminal and I will see you in the very next

20
00:57.150 --> 00:57.680
video where

21
00:57.680 --> 00:58.760
we will discuss the solution.
