00:00:00,000 --> 00:00:11,160
In this video, you'll learn how to create GPT partitions with ParThet.

2
00:00:11,160 --> 00:00:15,520
Now let me mention one thing, ParThet is not the only utility.

3
00:00:15,520 --> 00:00:21,459
You can also use fdisk and create a GPT partition, or use the gdisk utility instead.

4
00:00:21,459 --> 00:00:26,320
And depending on where you come from, you might find that a little bit more intuitive.

5
00:00:26,320 --> 00:00:30,100
As in ParThet, you need to use options that are a bit surprising.

6
00:00:30,100 --> 00:00:32,080
So how are you going to use ParThet?

7
00:00:32,080 --> 00:00:34,119
You need to open the ParThet shell.

8
00:00:34,119 --> 00:00:38,639
So ParThet dev sdb will open the ParThet shell on your sdb device.

9
00:00:38,639 --> 00:00:44,320
And access commands that allow you to work with it, like print, which will show the current

10
00:00:44,320 --> 00:00:45,720
partition type.

11
00:00:45,720 --> 00:00:52,560
MK label allows you to set either GPT or MBR, which is the MS-DOS partition label.

12
00:00:52,560 --> 00:00:58,480
MK part, which will prompt for the partition name, file system type, and start and end.

13
00:00:58,480 --> 00:01:03,400
This prompt for the file system type is rather confusing because it won't create a file system

14
00:01:03,400 --> 00:01:04,400
for you.

15
00:01:04,400 --> 00:01:07,599
It will just mark the partition in the appropriate way.

16
00:01:07,599 --> 00:01:11,320
Next, you can use print to verify what you've done so far.

17
00:01:11,320 --> 00:01:16,639
And assuming that you are happy, you can use quit to exit ParThet and update the partition

18
00:01:16,639 --> 00:01:18,040
table.

19
00:01:18,040 --> 00:01:22,080
Let me show you how to do this on an example disk.

20
00:01:22,080 --> 00:01:28,720
So once again, I'm starting with LSBLK, which is showing that my free device is NVMe 0 and 2.

21
00:01:28,720 --> 00:01:29,720
Good.

22
00:01:29,720 --> 00:01:35,720
So I'm using ParThet on dev NVMe 0 and 2.

23
00:01:35,720 --> 00:01:38,680
And there we can see the ParThet interface.

24
00:01:38,680 --> 00:01:44,559
At any time, you can use help for help about the commands that are available that can be

25
00:01:44,559 --> 00:01:48,360
useful if you get lost on this interface.

26
00:01:48,360 --> 00:01:52,040
Now I'm going to start with the print command.

27
00:01:52,040 --> 00:01:55,639
And the print command is giving me partition table unknown.

28
00:01:55,639 --> 00:01:58,199
Now that's a serious, serious situation.

29
00:01:58,199 --> 00:02:01,760
And that is why I need MK label GPT.

30
00:02:01,760 --> 00:02:05,559
And now we have the partition label set to GPT.

31
00:02:05,559 --> 00:02:12,000
Then I can use MK part primary, which is surprising, but it's a requirement in ParThet.

32
00:02:12,039 --> 00:02:20,399
I mean, GPT doesn't have the notion of primary and secondary and standard and logical partitions.

33
00:02:20,399 --> 00:02:22,880
GPT just has partitions.

34
00:02:22,880 --> 00:02:29,800
But ParThet, due to its compatibility with MBR, needs you to specify primary.

35
00:02:29,800 --> 00:02:32,800
Then I need to specify the use of the partition.

36
00:02:32,800 --> 00:02:35,119
And in this case, it will be ext4.

37
00:02:35,119 --> 00:02:40,080
That is also surprising because it doesn't do anything with that information.

38
00:02:40,119 --> 00:02:42,720
It doesn't add an ext4 file system.

39
00:02:42,720 --> 00:02:46,479
You still need to add the file system separately.

40
00:02:46,479 --> 00:02:47,880
0%.

41
00:02:47,880 --> 00:02:52,279
That's how I indicate that the partition should start at the beginning of my disk.

42
00:02:52,279 --> 00:02:56,759
And one gigabyte is the size of the partition.

43
00:02:56,759 --> 00:02:58,399
And now I'm going to repeat that.

44
00:02:58,399 --> 00:03:02,440
And I'm using MK part primary once more.

45
00:03:02,440 --> 00:03:04,919
And this time I'm using Linux swap.

46
00:03:04,919 --> 00:03:06,720
Linux swap is a partition type.

47
00:03:06,720 --> 00:03:08,399
We will talk about it later.

48
00:03:08,399 --> 00:03:11,639
And here you can set the partition type directly.

49
00:03:11,639 --> 00:03:14,000
Then I need to indicate where it should start.

50
00:03:14,000 --> 00:03:16,399
Well, it should start at one gigabyte.

51
00:03:16,399 --> 00:03:19,080
And it should end at six gigabyte.

52
00:03:19,080 --> 00:03:21,160
And that is doing it.

53
00:03:21,160 --> 00:03:22,679
Hey, we are working in the blind.

54
00:03:22,679 --> 00:03:24,320
I don't like this very much.

55
00:03:24,320 --> 00:03:30,759
So please use print so that you can verify what is going on and what it has done so far.

56
00:03:30,759 --> 00:03:32,440
And this is looking good.

57
00:03:32,440 --> 00:03:37,119
So I am going to use quit to write all of it.

58
00:03:37,119 --> 00:03:40,240
And that's telling me you may need to update ETCFS app.

59
00:03:40,240 --> 00:03:46,000
No, because I still need to use MKFS to create my file systems.

60
00:03:46,000 --> 00:03:47,839
Now, I want to show you a command.

61
00:03:47,839 --> 00:03:51,000
And this command is UDEF ADM settle.

62
00:03:51,000 --> 00:03:57,479
UDEF ADM settle is what the Parthet guys are recommending to update systemd UDEF

63
00:03:57,479 --> 00:04:01,240
and make sure that the devices are created throughout.

64
00:04:01,240 --> 00:04:05,279
On modern Linux, you won't need to do that very often anymore.

65
00:04:05,279 --> 00:04:08,240
But you are preparing for an exam.

66
00:04:08,240 --> 00:04:12,399
And in the exam, this might come in handy to know about it.

67
00:04:12,399 --> 00:04:14,479
And here you can see what is going on.

68
00:04:14,479 --> 00:04:15,759
And what has it done?

69
00:04:15,759 --> 00:04:20,239
Well, it has created two partitions, the P1 and the P2.

70
00:04:20,239 --> 00:04:24,920
And kind of funny, I asked it to create a one gigabyte partition.

71
00:04:24,920 --> 00:04:25,679
It did not.

72
00:04:25,679 --> 00:04:29,760
It created a 1,023 megabyte partition.

73
00:04:29,760 --> 00:04:35,679
And that is one of the reasons that I'm not sure that Parthet is the best utility.

74
00:04:35,679 --> 00:04:37,279
You know what I'm going to do?

75
00:04:37,279 --> 00:04:40,079
I'm going to show you how to do the same with FDisk.

76
00:04:40,079 --> 00:04:44,559
So FDisk on dev NVMe 0 and 2.

77
00:04:44,559 --> 00:04:46,559
Using P to print.

78
00:04:46,559 --> 00:04:50,200
And here we can see the partitions that have been created so far.

79
00:04:50,200 --> 00:04:52,399
Using M for the menu.

80
00:04:52,399 --> 00:04:58,320
Now, in FDisk, it's important to know that FDisk is an MBR-oriented utility.

81
00:04:58,320 --> 00:05:05,079
So if you want to create GPT, you really must use G to create a new empty GPT partition table

82
00:05:05,079 --> 00:05:07,480
before you do anything else.

83
00:05:07,480 --> 00:05:10,880
Now I'm going to use N to create a new partition.

84
00:05:10,880 --> 00:05:13,239
And I like it that FDisk is telling me something.

85
00:05:13,239 --> 00:05:16,480
Hey, it's suggesting me to create a default partition 3.

86
00:05:16,480 --> 00:05:19,279
And I can go up to 128.

87
00:05:19,279 --> 00:05:23,559
And then first sector, yeah, well, I'm just going to enter what it proposes.

88
00:05:23,600 --> 00:05:29,959
And last sector, I'm going to make that plus 1G for one gigabyte.

89
00:05:29,959 --> 00:05:34,320
And there we can see new partition 3 of type Linux file system.

90
00:05:34,320 --> 00:05:35,600
I'm using P.

91
00:05:35,600 --> 00:05:41,720
And there we can see that my very first partition that I created in Parthet is the type Linux file system.

92
00:05:41,720 --> 00:05:43,359
Oh, that is this one.

93
00:05:43,359 --> 00:05:47,160
And the FDisk partition is the type Linux file system as well.

94
00:05:47,160 --> 00:05:52,359
The funny thing is when in Parthet I specified I want an EXT4 partition,

95
00:05:52,359 --> 00:05:54,799
it doesn't do anything with EXT4.

96
00:05:54,799 --> 00:05:58,519
It just sets the partition type as Linux file system.

97
00:05:58,519 --> 00:06:00,359
And that is what it is doing.

98
00:06:00,359 --> 00:06:03,920
And here you can see that FDisk has done what I asked it to do.

99
00:06:03,920 --> 00:06:06,359
It created the one gigabyte partition.

100
00:06:06,359 --> 00:06:07,959
And that's what I wanted, right?

101
00:06:07,959 --> 00:06:09,480
So I'm happy with it.

102
00:06:09,480 --> 00:06:11,720
And I'm going to use W to write.

103
00:06:11,720 --> 00:06:15,880
And in case you are wondering, doesn't it hurt to use two different utilities?

104
00:06:15,880 --> 00:06:17,119
No, not at all.

105
00:06:17,119 --> 00:06:21,720
Because they are just two different ways to write information to your disk.

106
00:06:21,720 --> 00:06:23,160
And it just works.

107
00:06:23,160 --> 00:06:26,880
And that is what we confirm when we use LSBLK.

108
00:06:26,880 --> 00:06:31,440
There you go, three partitions on NVMe 0 and 2.
