My server has a partition and the disk size just 38GB, whereas I need about 20GB more for save my new files. With this condition I think have just two options between extend the partition before or add new disk and mount it into a folder within my partition before. Then I discuss with my friend which way is the best and the faster, finally I choose the second option which is add new disk (new partition, basically it will named as /dev/sdb/, /dev/sdc/, etc) and mount it into my specific folder, let say I will mount it into
So, how to extend new disk and mount it into our custom folder? here are the steps. This solution was tested successfully in my server Linux Centos 7.
# Check your which one is your new disk # you can check that with this sudo parted -l | grep Error # or this one # just make sure the free size still 100% lsblk # in my case I got /dev/sdb/ # so I started with this pvcreate /dev/sdb vgcreate diskaset /dev/sdb lvclear vgdisplay # Chek these line! # Alloc PE / Size 12799 / <50.00 GiB # Free PE / Size 0 / 0 # # 12799 refers to Free PE or Alloc PE lvcreate -l 12799 lv_diskaset diskaset # Format the disk into XFS # for "/disk/diskaset/" name it as you wish sudo mkfs.xfs /dev/diskaset/ sudo mkfs.xfs /dev/diskaset/lv_diskaset # Create folder for mount the disk mkdir /opt/lampp/htdocs/aset/ # Mounting mount /dev/diskaset/lv_diskaset /opt/lampp/htdocs/aset/ # Edit the "/etc/fstab" file for autostart when server startup # Save nano /etc/fstab/ # Add this line in the bottom /dev/diskaset/lv_diskaset /opt/lampp/htdocs/aset xfs defaults 0 0 # Reboot your server reboot
Finish, hope my solution above will help you sometime to extend and mount new disk into your custom folder for expanding storage in Linux Centos 7.
