Adding space to the Control Center thin pool

The procedures for adding additional space to a Control Center thin pool will vary depending on whether the data or metadata areas are being expanded.
Pay close attention to the following procedures.

Adding space to the metadata area of a Control Center thin pool

Use this procedure to increase the amount of space in the metadata area of a Control Center thin pool.

Log in to the master host as root or as a user with superuser privileges.
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.
Add space to the metadata storage area of the serviced thin pool.

In the following command: - Replace Size with the amount of space to add (in megabytes) and the units identifier (M). - 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.
```
lvextend -L+SizeM Volume-Group/Logical-Volume_tmeta
```

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.

Log in to the master host as root or as a user with superuser privileges.
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.
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.
```
lvextend -L+Total-SizeG Volume-Group/Logical-Volume
```
