MANAGING DISK SPACE WITH LVM

Thus far we have seen the development of two key operating system abstractions: the process, which is a virtualization of the CPU, and the address space, which is a virtualization of memory. In tandem, these two abstractions allow a program to run as if it is in its own private, isolated world; as i[r]

Thus far, we’ve assumed that an address space is unrealistically small and fits into physical memory. In fact, we’ve been assuming that every address space of every running process fits into memory. We will now relax these big assumptions, and assume that we wish to support many concurrentlyrunning la[r]

Beyond the basic advances found in the file systems we have studied thus far, a number of features are worth studying. In this chapter, we focus on reliability once again (having previously studied storage system reliability in the RAID chapter). Specifically, how should a file system or storage system[r]

In this chapter, we take a small detour from our discussion of virtualizing memory to discuss a fundamental aspect of any memory management system, whether it be a malloc library (managing pages of a process’s heap) or the OS itself (managing portions of the address space of a process).
