assuming that the underlying principle is not understood, even learning how to use the tool will be very quickly forgotten. Maybe I'm too old-fashioned. But I always remember what the teacher who taught computer programming said. Do not use the IDE before compiling a complete program in person with the command line.It's much easier to Kprobe and jprobe, and then to learn the tools that are based on their encapsulation. Once learned is more difficult to forget.PostScript: About PanicProgramming

taking over the services and resources of the host. This frees up the resources occupied by the exception node through the fence device, ensuring that the resources and services are always running on a single node. RHCs's fence devices can be divided into two types: internal fence and external fence, common internal fence with IBM Rsaii cards, HP's ILO cards, and IPMI devices, and external fence devices with UPS, SAN SWITCH, NETWORK Switch, etc.
