In this chapter, you learned:
Physical volumes, volume groups, and logical volumes are managed by a variety of tools such as
pvcreate,vgreduce, andlvextend.Logical volumes can be formatted with a file system or as swap space, which can be configured to be mounted or started when the system boots.
You can add additional storage to a volume group and use it to dynamically extend logical volumes.
Stratis provides an integrated way to assemble physical storage into pools that can be allocated automatically to file systems.
The Virtual Data Optimizer (VDO) is designed to reduce storage cost by optimizing storage efficiency, using zero-block elimination, data deduplication, and data compression.
Lab Controls
Click CREATE to build all of the virtual machines needed for the classroom lab environment. This may take several minutes to complete. Once created the environment can then be stopped and restarted to pause your experience.
If you DELETE your lab, you will remove all of the virtual machines in your classroom and lose all of your progress.
