Filesystem and Volumes
File system and volumes¶
In a Unix file system, there is only one root. However, the composition of a file system can come from a local disk, multiple local disks, or even the network (file sharing).
Under Unix, to keep a single tree, each tree (or part) other than the main file system is
mount) on the main tree.
On Linux, the table containing the set of volumes (tree) mounted on the main tree is obtained using the command
df makes it possible to also know all the volumes mounted but also their occupation.
