After expanding the disk in the control panel, you need to expand it at the operating system level.
Open a terminal as root and type the following commands:
[root@Serverspace ~]# echo 1 > /sys/block/sda/device/rescanRun the command below using fdisk:
[root@Serverspace ~]# fdisk /dev/sdaDelete the /dev/sda2 section:
Command (m for help): d
Partition number (1,2, default 2): 2Create a section:
Command (m for help): nSelect the section type (p) - main
Select (default p): p
Partition number (2-4, default 2): 2Press Enter twice - accept the values by default
First sector (XXX-YYY, default ZZZ):
Last sector, +sectors or +size{K,M,G} (XXX-YYY, default ZZZ):Change the section type
Command (m for help): t
Partition number (1-2): 2
Hex code (type L to list all codes): 8e
...Save the changes:
Command (m for help): wNotify the kernel of the change:
[root@Serverspace ~]# partx -u /dev/sda2Make changes to the physical volume:
[root@Serverspace ~]# pvresize /dev/sda2Now you need to get the name of the logical volume:
lvdisplayLook for the name of the volume ending with XXXXXXX/root (in the example below it is /dev/centos_vg/root).
--- Logical volume ---
LV Path /dev/centos_vg/swap
....
--- Logical volume ---
LV Path /dev/centos_vg/var
...
--- Logical volume ---
LV Path /dev/centos_vg/root
...Expand the logical volume:
[root@Serverspace ~]# lvextend -l +100%FREE /dev/XXXXXXX/root
......
Logical volume root successfully resizedExpand the file system:
[root@Serverspace ~]# xfs_growfs /dev/XXXXXXX/root
