A kernel panic often lives up to its name, causing panic for the admin. But the good news is that all is not lost; there are steps you can take.So, first...
In Chapter 3, we discussed some of the top-level disk devices that the kernel makes available. In this chapter, we’ll discuss in detail how to work with disks on a Linux system. You’ll learn how to partition disks, create and maintain the filesystems that go inside disk partitions, ...
To access data on a disk, the Linux kernel uses the system of layers shown in Figure 4-2. The SCSI subsystem and everything else described in 3.6 In-Depth: SCSI and the Linux Kernel are represented by a single box. (Notice that you can work with the disk through the filesystem as w...
you might need to upgrade lsof. In addition, if you perform a distribution update to both the kernel and lsof, the updated lsof might not work until you reboot with the new kernel. 注意:lsof高度依赖于内核信息。
Two other utilities for Linux, similar to top, offer an enhanced set of views and features: atop and htop. Most of the extra features are available from other utilities. For example, htop has many of abilities of the lsof command described in the next section. ...
