How to resize/extend Windows or Linux disk space (LVM)

If you buy a plan with more than 15GB of disk space, the remaining space is empty and need to be partitioned first.

If you have Windows, you simply go to Computer Management -> Disk Management to reclaim the empty space.

If you have Centos template, you can use below instructions on how to extend the LVM to include the free space.

1. SSH and login as root to your VPS
2. type pvs then vgs then lvs (Note the name under VG, here we have centos)
3. fdisk /dev/vda
To Create new partition Press n.
Choose primary partition use p.
Choose which number of partition to be selected to create the primary partition.
Press 1 if any other disk available.
Change the type using t.
Type 8e to change the partition type to Linux LVM.
Use p to print the create partition ( here we have not used the option) (note the new partition, usually /dev/vda3).
Press w to write the changes.
4. Restart the system once completed.
5. Once up, SSH again to your VPS
6. type

vgextend centos /dev/vda3

6. type vgdisplay and note the number next to Free then say the number you see on left side of / is 40970
7. type df and note your / partition Filesystem name (say /dev/mapper/centos-root)
8. type

lvextend -l +40970 /dev/mapper/centos-root

If you need to reduce it, you type

lvreduce -l -40970 /dev/mapper/centos-root

9 Finaly step is to resize it via command

resize2fs /dev/mapper/centos-root

9. type df to see your new size for / partition
