# Adding space to the data area of a Control Center thin pool

Use this procedure to increase the amount of space in the data area of a Control Center thin pool.
1. Log in to the master host as root, or as a user with superuser privileges.
2. Display information about LVM logical volumes on the host.
lvs --options=lv_name,vg_name,lv_size
Typically, the logical volume is serviced-pool and the containing volume group is serviced.
3. Add space to the data storage area of the serviced thin pool.
In the following command:
• Replace Total-Size with the sum of the existing device size plus the space to add to the device, in gigabytes. Include the units identifier, G.
• Replace Volume-Group with the name of the LVM volume group identified in the previous step.
• Replace Logical-Volume with the name of the logical volume identified in the previous step.
