13. Create a logical volume using all of the space. The command is formatted as follows:
sudo lvcreate –L (size of Volume) (name of volume group) –n (Logical Volume Name)
In most cases, you will be allocating all the free space in the logical volume to video storage. You can accomplish that by
substituting “-L (size of Volume) in the command above with “-l |100%FREE.” In this example, the command would look like
this.
sudo lvcreate –l +100%FREE ExacqStorageServer01 –n Video_Storage_01
If you do not want to use all the space, you must specify the size. In this example, two 2TB volumes have been added at
3999.99G. To determine smaller volumes, use the figure 99.997 for every 100GB allocated in a disk. If you are close to using
all of the space, the system will round up to use all the space.
The volume group name should be the name that you provided earlier. You could use a name like Video_Storage_XX,
where XX is an incremental number for the syntax of the LV name:
sudo lvcreate –L 3999.99G ExacqStorageServer01 –n Video_Storage_01
14. You can now view you new volume using the lvs command:
15. Format the Logical volume using the ext4 format. There are a number of information-gathering steps that should be done
first before proceeding with the format.
The new device created will exist in a new directory with the name of the volume group. Use the lvscan command to get
the full path.
