How to create LVM on Fedora 34

To Create And Manage LVM on Fedora 34.

Introduction:

Logical volume management (LVM) is a form of storage virtualization that offers system administrators a more flexible approach to managing disk storage space than traditional partitioning. This type of virtualization tool is located within the device-driver stack on the operating system.

Step 1: Check the OS version by using the below command.

[root@linuxhelp ~]# cat /etc/os-release
NAME=Fedora
VERSION="34 (Workstation Edition)"
ID=fedora
VERSION_ID=34
VERSION_CODENAME=""
PLATFORM_ID="platform:f34"
PRETTY_NAME="Fedora 34 (Workstation Edition)"
ANSI_COLOR="0;38;2;60;110;180"
LOGO=fedora-logo-icon
CPE_NAME="cpe:/o:fedoraproject:fedora:34"
HOME_URL="https://fedoraproject.org/"
DOCUMENTATION_URL="https://docs.fedoraproject.org/en-US/fedora/34/system-administrators-guide/"

Step 2: Check the disk block by using the below command

[root@linuxhelp ~]# lsblk
NAME   MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
sda      8:0    0   20G  0 disk 
├─sda1   8:1    0    1G  0 part /boot
└─sda2   8:2    0   19G  0 part /home

sdb      8:16   0   30G  0 disk 
sdc      8:32   0   10G  0 disk 
sr0     11:0    1  1.9G  0 rom  /run/media/linuxhelp/Fedora-WS-Live-34-1-2
zram0  252:0    0  4.1G  0 disk [SWAP]

Step 3: Create a new Partition by using the below command.

[root@linuxhelp ~]# fdisk /dev/sdb

Welcome to fdisk (util-linux 2.36.2).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

Device does not contain a recognized partition table.

Changed type of partition 'Linux' to 'Linux LVM'.

Command (m for help): w
The partition table has been altered.
Calling ioctl() to re-read partition table.
Syncing disks.

Step 4: Once all the modification is done in the partition, restart it by using the below command.

[root@linuxhelp ~]# partprobe

Warning: Unable to open /dev/sr0 read-write (Read-only file system).  /dev/sr0 has been opened read-only.

Step 5: Now Check the disk block by using the below command

[root@linuxhelp ~]# lsblk
NAME   MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
sda      8:0    0   20G  0 disk 
├─sda1   8:1    0    1G  0 part /boot
└─sda2   8:2    0   19G  0 part /home
sdb      8:16   0   30G  0 disk 
└─sdb1   8:17   0   10G  0 part 
sdc      8:32   0   10G  0 disk 
sr0     11:0    1  1.9G  0 rom  /run/media/linuxhelp/Fedora-WS-Live-34-1-2
zram0  252:0    0  4.1G  0 disk [SWAP]

Step 6: Create the Physical volume by using the below command.

[root@linuxhelp ~]# pvcreate /dev/sdb1
  Physical volume "/dev/sdb1" successfully created.

Step 7: Create the Volume group by using the below command

[root@linuxhelp ~]# vgcreate test /dev/sdb1
  Volume group "test" successfully created

Step 8: Create a Logical volume by using the below command.

[root@linuxhelp ~]# lvcreate -n check -L 8G test
  Logical volume "check" created.

Step 9: Check the disk block by using the below command.

[root@linuxhelp ~]# lsblk
NAME           MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
sda              8:0    0   20G  0 disk 
├─sda1           8:1    0    1G  0 part /boot
└─sda2           8:2    0   19G  0 part /home
sdb              8:16   0   30G  0 disk 
└─sdb1           8:17   0   10G  0 part 
  └─test-check 253:0    0    8G  0 lvm  
sdc              8:32   0   10G  0 disk 
sr0             11:0    1  1.9G  0 rom  /run/media/linuxhelp/Fedora-WS-Live-34-1-2
zram0          252:0    0  4.1G  0 disk [SWAP]

Step 10: Make the directory by using the below command.

[root@linuxhelp ~]# mkdir /test

Step 11: Make the file system by using the below command.

[root@linuxhelp ~]# mkfs.ext4 /dev/test/check
mke2fs 1.45.6 (20-Mar-2020)
Creating filesystem with 2097152 4k blocks and 524288 inodes

Creating journal (16384 blocks): done
Writing superblocks and filesystem accounting information: done 

Step 12: Check the file type by using the below command.

[root@linuxhelp ~]# blkid
/dev/sr0: BLOCK_SIZE="2048" UUID="2021-04-23-11-17-40-00" LABEL="Fedora-WS-Live-34-1-2" TYPE="iso9660" PTUUID="6b5ab614" PTTYPE="dos"

/dev/sdb1: UUID="h26Z9p-LEJj-WWxe-Nor2-EohF-k18P-izPD6P" TYPE="LVM2_member" PARTUUID="ed5cec9d-01"
/dev/zram0: LABEL="zram0" UUID="099d2ce6-edd7-4808-a5d0-7719e84a3cd5" TYPE="swap"
/dev/mapper/test-check: UUID="e53bc8f0-8c55-495d-b9ad-b7783f4e7ef1" BLOCK_SIZE="4096" TYPE="ext4"

Step 13: Open the fstab configuration file by using the below command.

[root@linuxhelp ~]# vim /etc/fstab
/dev/sda2: LABEL="fedora_localhost-live" UUID="89d93d80-44ff-48c1-a84b-293ca2db9b3c" UUID_SUB="fc6cdf76-8e4e-4827-8821-aefedc9b76f6" BLOCK_SIZE="4096" TYPE="btrfs" PARTUUID="3f94edf1-02"

/dev/sdb1: UUID="h26Z9p-LEJj-WWxe-Nor2-EohF-k18P-izPD6P" TYPE="LVM2_member" PARTUUID="ed5cec9d-01"
/dev/zram0: LABEL="zram0" UUID="099d2ce6-edd7-4808-a5d0-7719e84a3cd5" TYPE="swap"
/dev/mapper/test-check: UUID="e53bc8f0-8c55-495d-b9ad-b7783f4e7ef1" BLOCK_SIZE="4096" TYPE="ext4"

Step 14: To Mount use the below command.

[root@linuxhelp ~]# mount -a
mount: /dev/mapper/test-check: mount point is not a directory.

Step 15: To change the directory and list the files use the below command

[root@linuxhelp ~]# cd /dev/test/
[root@linuxhelp test]# ls -l
total 0
lrwxrwxrwx 1 root root 7 Dec  7 21:15 check -> ../dm-0

Step 16: To move the files source to destination and change directory use the below command.

[root@linuxhelp test]# mv check1 check
mv: cannot stat 'check1': No such file or directory
[root@linuxhelp test]# cd

Step 17: change the directory by using the below command.

[root@linuxhelp ~]# cd /dev/test/
 [root@linuxhelp test]# ls -l
total 0
lrwxrwxrwx 1 root root 7 Dec  7 21:15 check -> ../dm-0

Step 18: Make the directory by using the below command.

 [root@linuxhelp test]# mkdir check1

Step 19: To move the directory and list the file use the below command.

 [root@linuxhelp test]# mv check check1

 [root@linuxhelp test]# ls -l
total 0
drwxr-xr-x 2 root root 60 Dec  7 21:24 check1

Step 20: To make the directory use the below command.

[root@linuxhelp test]# mkdir check

Step 21: To mount and list the directory use the below command.

[root@linuxhelp test]# mount -a
[root@linuxhelp test]# lsblk
