Lab 10 part 2. Verifying new disks This lesson focuses on initializing new disks that have been thin provisioned. In this lab-based lesson, participants receive step by step instructions in how to initialize disks that are thin provisioned and inflating them to their full size.

Video Transcription

00:04
Okay, so now let's log into this system
00:09
and verify that we can see the new disc that was added.
00:24
So I opened up Windows Explorer.
00:27
I could see that I still have have not expanded this particular drive even though I have extended the partition
00:33
and I don't see
00:35
my new desk.
00:38
So what I need to do is
00:41
go back to mine,
00:46
creating four man hardest partitions or just management tool.
00:52
That tells me that it found a new disk,
00:55
and I can go ahead and initialize this
00:58
notice. You get the option to use the N b E r G P T format.
01:03
You would only use GPT
01:06
if the disk was larger than two terabytes. So this is only three gigabytes. I'll just stick with standard NPR.
01:15
All right, so now I'm the first task. Let's expand this partition, since I needed to do that from earlier
01:22
extend that volume,
01:23
adding the one gigabyte of unallocated space.
01:27
OK, that's done.
01:30
Now I have a
01:32
A new disk. Just 10 was my C drive,
01:36
and this disc is basically
01:38
ready to use.
01:42
It's a
01:45
rob device mapping, so there's nothing on this system right now. Okay, So in order for me to use this this storage with this virtual machine, I still have to
01:53
right click the volume
01:57
saying that it's a new, simple volume.
01:59
I can specify its size. I could just use the maximum available here
02:04
and even give it a new drive letter.
02:07
Or I could mount it as an anti F s
02:12
file system
02:14
to an existing folder. But right now, I'm just gonna make it a regular Dr.
02:19
And we get our usual choices
02:22
for doing a quick format.
02:25
All right, now that disk is usable.
02:30
So if I go back to
02:32
my computer and refresh the screen, I can see that I've got
02:37
my additional space available on the C drive
02:39
and my new volume with three gigabytes available Space is now ready for use.
02:45
Okay, cellar. Next task.
02:49
Since we wantto
02:51
extend
02:52
expanding a thin provisioned disc
02:54
first we're going to need to shut down this virtual machine.
03:06
And then what I'm going to do is add
03:08
another virtual disc
03:10
as a thin provisioned disk, and then we will see some of the changes that happened,
03:15
Uh,
03:16
when the discus formatted and also when we try to inflate it to its full size,
03:23
So we'll go back to edit settings.
03:30
I'm going to add
03:31
her disk.
03:35
In this case, I'm gonna create a new virtual death. Last time we added a rod device mapping,
03:42
so it doesn't need to be very big.
03:46
We'll just make it
03:47
to gig.
03:49
Mmm.
03:50
And I'll select thin provisioning
03:53
if you'll recall from our earlier discussion.
03:54
Thin provisioning means that can eventually get to two gigabytes and size,
04:00
but it's
04:01
when it's provisioned. It starts off with a very small amount of storage and grows as needed,
04:09
so this allows for quicker provisioning. But you do take a slight hit and performance because the disk file needs to be expanded, as data has written to the desk.
04:19
Anyways, we'll stick with thin provisioning,
04:24
pick the defaults cosy node,
04:27
and I'll go ahead and click finish. And it says that now it's adding that disk.
04:36
Okay,
04:38
now what I'd like to do is
04:41
look at the data store
04:45
for Win seven.
04:46
So got my summary tab
04:47
selected, and I could just right click my dear storm browsing.
04:55
So the first disc
04:57
is in the wind. Seven folder.
05:00
Ah, the second disk, which goes to the raw mapping
05:02
is seven underscore one,
05:05
and then win seven. Underscore, too,
05:09
is my new
05:11
desk.
05:12
You'll notice that
05:14
the provision size is
05:15
two gigabytes,
05:19
but the actual sizes zero.
05:25
So a couple things that we need to think about here. If I were to form at this disk
05:30
within the guest operating system,
05:32
the size would change. It would go to AA couple 100 kilobytes,
05:39
I believe, for a size for disk this large.
05:43
But what I want to do now is
05:46
just what the what the
05:50
the disc. In a raw format with no file system, I still want to be able to grow it to its full provision size just to see that this is possible.
06:00
So what we can do is right. Click and select Inflate.
06:08
This will take a little bit of time,
06:10
tells you where which host it's on
06:13
and which,
06:15
rather which data stores on and which folder V. M d K file exists.
06:24
So
06:26
if I were to ah,
06:28
inflate this disk, it wouldn't matter, really. If I had a file system on the disk already or not,
06:32
it would still work the same way. The only major drawback
06:38
for this operation is that the machine must be powered down for this step
06:45
once. Once that completes,
06:48
then we should be able to look at the provisions provisions to size and the regular size, and they should more or less match up.
07:00
All right, now we can see that
07:02
the size of the the disc has now grown to the full two gigabytes.
07:09
The provision size no longer has a
07:12
entry here because now we've expanded
07:15
to the full provision size. There's no reason to list that information redundantly.
07:20
And if we look at the summary tab for this P. M,
07:26
we can see that we've got our
07:28
provisions storage here,
07:30
showing the new total available storage and the total that we see is the sum of all the
07:36
just sort of been allocated weaken
07:39
double check that
07:43
go back at it settings
07:45
and we can look at our disks.
07:47
I got one just that's 12 gig.
07:51
We've got another.
07:54
Ah, that is
07:56
three gigs. I remember
07:58
another one. That's true.
08:05
I'm sorry that the raw match one is eight.
08:09
I believe that's a kicker bites.
08:11
In either case,
08:13
this is the total provisions storage for the entire VM
08:16
with the various different disks that we've attached.
08:24
Okay, so we've we've added, Ah, a rod device disc.
08:30
We've added another virtual disk that was thin, provisioned, and then we,
08:33
uh,
08:35
inflated it to its full size,
08:37
which is basically they whipped the equivalent of doing a thick provisioning where you build the entire
08:43
storage container
08:43
when it when the VM is created.
08:48
And we also increase the memory for this V m.
08:50
So that concludes Lab 10
08:54
in lab 11.
08:56
What we'll be doing is working with migrating virtual machines
09:00
where we can use things like
09:03
of emotion and storage of emotion.
09:05
All right, See you in, lad. 11. Thank you.
