How to Create LVM in Linux Step by Step

-

1. Add the new disk As Per requirement in your VM. ( I have add 5GB Disk Space for create the LVM. )


2. create a new Partition using fdisk tool and select partition type LVM : 

[root@rajeev ~]#  lsblk 

[root@rajeev ~]#  fdisk /dev/vdb 

[root@rajeev ~]#  partprobe /dev/vdb

[root@rajeev ~]#  cat /proc/partitions 








3. Initializes the partition /dev/vdb1 as an LVM physical volume :

[root@rajeev ~]# pvcreate /dev/vdb1

  Physical volume "/dev/vdb1" successfully created.


4. Displaying Physical Volumes :  ( You Can Use Any One Command. )

[root@rajeev ~]#  pvs /dev/vdb1

[root@rajeev ~]# pvdisplay /dev/vdb1



5. Create volume group name myvg and add /dev/vdb1 partition into the group.

[root@rajeev ~]# vgcreate myvg /dev/vdb1

  Volume group "myvg" successfully created




6. Creates a logical volume called lv_myvg that uses all of the unallocated space in the volume group vg_newlvm :

[root@rajeev ~]# lvcreate -l 100%FREE -n lv_myvg myvg

  Logical volume "lv_myvg" created.



7. Use the mkfs command to format a newly created LVM :

[root@rajeev ~]# mkfs.ext4 /dev/myvg/lv_myvg



8. Create the mount point and mount the new LVM :

[root@rajeev ~]# mkdir /mylvm
[root@rajeev ~]# mount /dev/myvg/lv_myvg  /mylvm/
[root@rajeev ~]# df -h



9. For Permanent mounting 

[root@rajeev ~]# vim /etc/fstab  ( And Add Below Line. )

/dev/myvg/lv_myvg       /mylvm/         ext4    defaults        0 0

 10.  For Test fstab entry.  

[root@rajeev ~]# df -h
[root@rajeev ~]# umount /mylvm
[root@rajeev ~]# df -h
[root@rajeev ~]# mount -a
[root@rajeev ~]# df -h
