Listing 1. Bad habits 1 Example: define each directory tree separately
~ $ Mkdir TMP~ $ CD TMP~ /Tmp $ mkdir~ /Tmp $ CD~ /Tmp/A $ mkdir B~ /Tmp/A $ CD B~
this time, the third and fourth disks are idle. When B data is written to the third Disk in a certain band, and B data is checked in the fourth disk, in this way, both data a and data B can be read and written at the same time.
