1 00:00:00,000 --> 00:00:09,000 All right, let's investigate the storage topology. 2 00:00:09,000 --> 00:00:10,720 A lot of storage going on. 3 00:00:10,720 --> 00:00:15,440 It looks as if NVMe 0 and 2 is the best one to use. 4 00:00:15,440 --> 00:00:21,959 So I am going to do an fdisk on dev NVMe 0 and 2 5 00:00:21,959 --> 00:00:24,000 to create two new partitions. 6 00:00:24,000 --> 00:00:26,280 Let me use Control-L to put the output 7 00:00:26,280 --> 00:00:27,600 on the top of the screen. 8 00:00:27,600 --> 00:00:30,639 Using N to create partition number 5. 9 00:00:30,639 --> 00:00:33,279 The lab is not asking for a specific size, 10 00:00:33,279 --> 00:00:36,439 so I'm making it a 1G partition. 11 00:00:36,439 --> 00:00:39,279 Using N to create partition number 6. 12 00:00:39,279 --> 00:00:42,720 Same story, plus 1G. 13 00:00:42,720 --> 00:00:44,680 This is going to be used for LVM, 14 00:00:44,680 --> 00:00:48,439 so we should not forget to set the partition type. 15 00:00:48,439 --> 00:00:52,759 For partition number 6, the alias that we can use is LVM. 16 00:00:52,759 --> 00:00:55,799 And likewise, T for partition number 5, 17 00:00:55,799 --> 00:00:58,279 and the alias is LVM. 18 00:00:58,279 --> 00:01:01,520 And now a quick P to verify what we have done. 19 00:01:01,520 --> 00:01:05,279 And as you can see, we have partition 5 and partition 6. 20 00:01:05,279 --> 00:01:06,160 Looking good. 21 00:01:06,160 --> 00:01:09,720 So W, and that will write it. 22 00:01:09,720 --> 00:01:14,559 Quick LSB OK to verify that partitions 5 and 6 show up 23 00:01:14,559 --> 00:01:17,120 as expected, and they do. 24 00:01:17,120 --> 00:01:20,239 Right, next we need to create an LVM volume group. 25 00:01:20,239 --> 00:01:24,559 I'm going to use VG Create, calling it VGLab, 26 00:01:24,559 --> 00:01:33,919 and putting in dev NVMe0 N2P5, as well as dev NVMe0 N2P6. 27 00:01:33,919 --> 00:01:35,360 Hey, hold on. 28 00:01:35,360 --> 00:01:39,120 Don't we have to create the physical volumes first? 29 00:01:39,120 --> 00:01:41,040 Yes, that's what I explained, because I 30 00:01:41,040 --> 00:01:43,440 want you to be aware of every single step. 31 00:01:43,440 --> 00:01:47,160 But the LVM utilities in general are quite smart. 32 00:01:47,160 --> 00:01:49,839 And that means even if you don't specifically 33 00:01:49,839 --> 00:01:52,879 create the physical volume, VG Create 34 00:01:52,919 --> 00:01:55,400 will find the partitions, will notice, hey, 35 00:01:55,400 --> 00:01:57,440 this is not a physical volume yet, 36 00:01:57,440 --> 00:01:59,519 and it will write the physical volume 37 00:01:59,519 --> 00:02:02,519 metadata to the partition, with the result 38 00:02:02,519 --> 00:02:06,040 that the volume group is successfully created. 39 00:02:06,040 --> 00:02:08,320 That makes it a bit easier, isn't it? 40 00:02:08,320 --> 00:02:12,639 Then we need to create a logical volume, so LVCreate. 41 00:02:12,639 --> 00:02:17,240 And how about the 75% of available disk space? 42 00:02:17,279 --> 00:02:23,360 Well, you would use minus L, lowercase L that is, 75% free. 43 00:02:23,360 --> 00:02:29,839 Minus N, because we want to give it a name, LVLab in VGLab. 44 00:02:29,839 --> 00:02:32,520 And now I want to do a quick LVS to verify 45 00:02:32,520 --> 00:02:34,639 that this worked out all right. 46 00:02:34,639 --> 00:02:35,520 And what do we see? 47 00:02:35,520 --> 00:02:38,839 We see that LVLab has a size of 1.5 gigs, 48 00:02:38,839 --> 00:02:41,759 and that is exactly what we needed. 49 00:02:41,759 --> 00:02:51,520 So mkfs.ext4 on dev VGLab LVLab to create an ext4 file system. 50 00:02:51,520 --> 00:02:54,880 And that is all that was required in this lab.
