For a hard disk with three partitions: 100 M, 100 M, and 200 M, what if one day M cannot be installed? Can I divide some space of the newly added hard disk into MB space? The logical volume can be implemented, which means we can dynamically increase

1. basic concept: physical volume (pv): a physical volume can be a hard disk or a partition on the hard disk. create a physical volume using pvcreate/dev/sdb1. volume Group (vg): a volume group consists of physical volumes. you can add or delete
